Opis:: Structure of the fleet of the passenger cars registered in Poland in the 1991-2006 years has undergone significant changes due to a dynamically developing situation, both on the domestic and international automotive market. Over the last fifteen years there has been a growing tendency observed in Poland, which led to an over twofold increase of passenger cars being registered. Changes in both makes and age structure of the fleet of the passenger cars registered in Poland are affected by fluctuations of sales figures of the new cars, but first of all by the used cars import. The 90-ties brought about an improvement in the financial situation of certain social groups in Poland as well as increased availability and ease to obtain loans to buy cars. This resulted in the increase of the new passenger cars sales. Since 2000 there has been a decreasing tendency observed in this aspect, but at the same time growing interest in the individual import of used passenger cars to Poland. Especially, since Poland's accession to European Union on the 1-st of May 200 Analysis of both makes and age structure of the fleet of the passenger cars registered in Poland for the first time in the years 2004-2006 as well as those removed from the register, indicates a constant growth in the population of old cars, and increase of their share in the car fleet structure. In the period under scrutiny, cars removed from the register, were dominated by the cars of at least mp-teen years of age, including those over 20 years. Those removed from the register were first of all the cars of makes and models whose low technological quality, and additionally high fuel consumption, excluded them from their further economical and safe usage.

Opis:: The article presents political and legal aspects regarding the recommendation for the development of hydrogen technology in the economy and in transport. The development of electric cars with hydrogen-powered fuel cells, which took place in recent years in the world, has been outlined. The principles of calculation of average vehicle operating costs applicable in the transport economics are discussed. The estimated average unit operating costs of a statistical passenger car using conventional energy carriers, estimated in the studies of the Motor Transport Institute are quoted. The assumptions and results of the estimation of the average cost per 1 vehicle-kilometre of the electric passenger car’s mileage (BEV) have been presented, as well as the assumptions and results of the estimation of the average unit operating costs of a hydrogen powered passenger car (FCEV). The average unit costs of the mileage of these vehicles have been compared. The predictions regarding the future changes in the average prices of FCEV vehicles have been cited and the average unit costs of operating electric cars with fuel cells by the 2050 have been estimated. The project of administrative support for the development of low-emission transport in Poland was indicated.

Opis:: The thermal management system is the one most important unit in the electric car which controls temperature of electric devices by obtaining a stability of their operation in different load and ambient conditions. For the other side the removable pack installed in the closed cradle for easier service during exchange of the modules should be cooled by the air. It is also better for safety during exploitation for the vehicle parts and people. The paper presents the proposal of ventilation of battery packs, assumptions of the battery pack cooling system, mathematical model of heat exchange and graphical results obtained from simulation carried out using the CFD program. During modelling it took into account two models: two-dimensional and three-dimensional for evaluation of the air flow and cooling rate of the battery modules. It was assumed four modules in one row of the cradle with total electric capacity above 4 kWh. The paper shows geometry of the whole battery unit with ventilation passages in 3D configuration. The aim of the work was determination of thermal parameters of the battery modules cooled by the air flow in the close chamber. The proposed cooling model of the cradle with air flow caused by fans in the pipe inlet shows that it is not possible to decrease temperature in the same way of each battery modules.

Opis:: Personal cars are the largest group of vehicles on the road. Every year a significant increase in this group of vehicles enforces the need to shorten the time of the study of the technical condition on vehicle inspection stations. One of the major components checked during the inspection is vehicle suspension that has a decisive influence on the comfort and safety. Currently, vehicle inspection stations to assess the condition of the suspension mainly use EUSAMA method, which allows obtaining approximate results. The paper presents the verification of the effectiveness and operation of the developed method called Procedure of Matrix Decimation (PMD), which allows for useful application of research results using FFT spectral analysis of nonstationary, transient signals recorded on the vehicle during the EUSAMA test method. Verification of this method of signal processing was done with the use of vibration signals recorded on the vehicle during the EUSAMA test method on vehicle inspection stations. It consists of a comparison of the FFT spectra obtained for the secondary signal (after processing method based on PMD) with STFT analyzes made for the original signal.

Opis:: The article presents scenarios for the EU and national development of passenger electric and hybrid cars. The forecast for 2030 of the shares of such vehicles in the total number of new passenger cars sold in various categories in the EU, has been presented. The expected carbon dioxide emissions for this time horizon, in so-called, life cycle of cars in the EU and in Poland, in relation to conventionally powered passenger cars and electric and hybrid cars, have also been presented The results of surveys conducted by the Motor Transport Institute on the interest of residents of the Polish agglomerations in the acquisition and operation of the electric cars in the coming years have been d. Questions and answers referred to the socio - demographic structure of the respondents and their households, the number of classes of the cars owned, monthly household income and self-evaluation of the quality of the income management. Also, the questions were asked about the ownership and extent of use (frequency of use of a car owned and the average annual mileage) and the criteria for the current and future choices of passenger cars (e.g. price class, purpose). The questions also concerned the technical and economic knowledge of electric cars (such as the impact on the natural environment, operating costs), as well as willingness to incur possible costs associated with the purchase of an electric car. The focus was also placed on getting to know the vulnerability of the consumers to the influence of the actions of the propaganda, administrative and economic nature, which may affect the consumers’ decisions concerning the purchase of electric cars and learning about the reasons for any reluctance to use such vehicles.

Opis:: The fact that we live in a new era of informational civilization compels us to fulfil new requirements also in the area of transportation and motorization. The paper deals with the problems of the cars of the first years of our century. Basic assumptions for the concepts of such cars are as follows: alternative forms of personal transportation are inevitable, cars must be environment friendly and friendly for human beings, and general design concept of the cars will not be changed. Some examples of such vehicles are presented using the concept of ultra light automobiles described by Q .R. Riley. The paper also describes "zero emission" cars and there are mentioned ideas of the vehicles with engines which are yet known in the sphere of science-fiction only. Design requirements for construction of future cars, ideas on construction of cars of the future as well as requirements which should realize motor vehicles friendly to humans and the environment, example solutions of various technical nature which can contribute to fulfilment of requirements imposed on SPNS and the proposal according to the author (R. Q. Riley) of Alternative cars in the 21st Century [3] are represented in the paper.

Opis:: The automotive market is developing very dynamically. In recent years, we can observe activities of automotive concerns in the production of new models of electric, hybrid and hydrogen vehicles, and conventional cars are supplied with increasingly economical and low-emission engines. There are also increasingly stringent standards related to exhaust emissions from the exhaust system. From September 1, 2018, passenger cars have to comply with the Euro 6d-Temp emission standard and be homologated according to the WLTP test procedure including the WLTC driving cycle and emission measurements in road traffic conditions. The exhaust components measured during the test, such as carbon oxides, nitrogen oxides or hydrocarbons, are toxic to living organisms. However, it seems that the most important issue in the long term may be the value of carbon dioxide emissions, the excess of which poses an ecological threat to the entire planet. The production of new vehicles equipped with modern complicated combustion engines, batteries, fuel cells and electronic devices is associated with a very high emission of this greenhouse gas The authors of the following article, based on their own research, sought to estimate the ecological profitability of replacing a used passenger car meeting the Euro-4 emissions standard for a new vehicle bearing in mind the value of carbon dioxide emissions during vehicle production. The analysis was to indicate how intensive the annual operation of the vehicle should be to make it profitable to recycle and replace it with a modern car with lower emissions considering the global sum of carbon dioxide emissions.

Opis:: The article discusses the development of the world EV fleet in years 2010-2017. Estimates of fleet of plug-in hybrid electric vehicles (PHEV) and BEV in the world are presented. The total number of PHEVs registered in the world in 2016 was roughly 800 thousand (650 thousand in EU). Despite the fact that the sale of electric vehicles has increased considerably in recent years, in particular over 1.1 million in 2017, and also hybrid electric vehicles (PHEV) to approx. 760 thousand in 2017. The article also discusses the development of the electric vehicles market and annual new registrations of vehicles in a breakdown into respective countries. China is the definite leader in this area. In 2017 there were almost twice more BEVs registered in China than in the US and EU together. While the increase in the sale of BEVs in years 2016-2017 in the EU and the US accounted for approx. 50%, it came to over 90% in China. Among eight top worldwide BEV producers, there are four Chinese manufacturers. In the analysed 2017, there were slightly more than 7 thousand of hydrogen-fuelled passenger cars (FCEV) in use, with over 3,500 in the US, 2,300 in Japan and approx. 1,200 in Europe, and several hundred hydrogen-fuelled buses and several dozen hydrogen-fuelled trucks. The article also addresses the development of hydrogen refuelling stations (HRS) in recent years in different countries in the world, bearing in mind that the quantitative development of the hydrogen-fuelled car fleet is strongly associated with the number of hydrogen refuelling stations.

Opis:: In this paper research results of ability vibration's suppression steel and composite leaf springs were presented. Polymeric composite leaf springs and steel were studied. Composite leaf springs were made from epoxy-glass composite reinforcement by glass fibre. Composite springs became designed to can replace steel spring of van. Executed investigations base on dynamic loadings of leaf springs and registering of vibrations amplitude and reaction of props. Load was realized through lowering from definite height of mass which hit into spring wresting it from balance. Mass stayed on spring to total atrophy of vibrations. Measured and registered parameters permitted to count logarithmic decrement suppressions of tremblings and coefficient of suppression of tremblings. This coefficient was counted for composite and steel leaf springs. Basic exploational parameters of leaf springs were compared as well as basic advantages of applying to vehicles building of composite materials were analysed. Analyses lead to conclusion that composite leaf springs in comparison to steel springs: about three times better suppress of tremblings, they are about five times lighter and give smaller dynamic burdens of vehicles body. Wide applying of composites materials on carrying structures of vehicles will contribute to lower of vehicles mass and to decrease of emission greenhouses gases.

Opis:: The invisible nanoparticles (NP) from combustion processes penetrate easily into the human body through the respiratory and olfactory ways and carry numerous harmful health effects potentials. NP count concentrations are limited in EU for Diesel passenger cars since 2013 and for gasoline cars with direct injection (GDI) since 2014. The limit for GDI was temporary extended to 6 x 1012 #/km. Nuclei of metals as well as organics are suspected to significantly contribute especially to the ultrafine particle size fractions, and thus to the particle number concentration. In the present paper, some results of investigations of nanoparticles from four gasoline cars – an older one with MPI and three never with DI – are represented. The measurements were performed at vehicle tailpipe and in CVS-tunnel. The results show that the older vehicle with MPI emits high particle count concentrations. The size distributions of this vehicle are decisively bimodal with high numbers in nuclei mode. The emissions of the newer vehicles with DI show sometimes no typical uniform shape of particle size distributions and are at lower level, than for the older vehicle. There is no visible nuclei mode and the ultrafine particle concentrations below 10 nm are insignificant. Some of the newer, low-emitting vehicles show at constant speed operation a periodical fluctuation of the NPemissions. Increased NP-emissions at cold start were confirmed.

Opis:: The article provides a discussion upon the structure of a measuring head designed and manufactured with the purpose of acquisition of data required by a diagnostic system for hydraulic telescopic shock absorbers of passenger cars operating based on vibroacoustic methods. The basis for the design development was a set of initial assumptions adjusted to the multidimensional methods of analysing vibration signals applied. For the design of the measurement track, a block diagram was proposed which was then extended by auxiliary electronic elements of the measuring system conforming with all the relevant requirements. The main components of the measurement track included: a three-axis sensor for vibration acceleration constructed based on one-axis converters, an angular displacement sensor usedfor measuring the rotation angle and linear velocity of a car and a laser road unevenness sensor. For the computer recording of the signals being measured, an analogue-digital cardwas used. The measuring head in question was mounted on a measuring trolley and then test and trial examinations were conducted while driving at various speeds up to 50 km/h in normal operating conditions. The repeatability of the measurement results obtained proved the measuring head's usability in testing.

Opis:: Police cars are very often driven as priority vehicles, reaching high speed in the open road traffic. That is why the parameters related to vehicle stability and steerability should be very high. This paper is an attempt to answer the question to what extent a typical driver can feel, and what is more important – take advantage of technical changes in the chassis in order to increase the speed in the performance of a test, or to enhance the safety of the drive. In this paper the authors attempt to assess to what extent the results of measurements of vehicle dynamics are affected by the driver and to what extent by particular technical solutions. The work was carried out under research and development project no. OR00000911 "Determination of the technical requirements and the equipment necessary in police cars on the basis of tests on model demonstrators" and previous results obtained in tests carried out in the Military Institute of Armored and Automotive Technology (WITPiS).The tests were carried out on the basis of a KIA CEED, currently one of the models most frequently used by the Police.

Opis:: Regenerative braking and damping are effective approaches for electric cars to extend their driving range. A disk Faraday generator regenerative braking strategy integrated with controlled charging of a supercapacitor is developed in this article to advance the level of energy-savings on the car board. The kinetic energy of the car suspension during driving regenerated effectively to electric energy by using shock absorber is harvested and then used to charge the vehicle’s battery, the power electronics and the supercapacitor. One of the advantages of supercapacitors is their high power capability, which is applicable for high rate of charging and discharging operations like motor starting and regenerative braking of an electric vehicle. This article presents a new charging method for supercapacitors. Common for regenerative braking and damping chargers for supercapacitors are usually equipped with electronic PWM converter performing two states of operation per switching cycle. A simple open-loop control system is applicable for the whole charging state. The proposed circuit consists of a minimum number of components. It is free of stability problem and protects itself from being overloaded by supercapacitor with zero initial charge. Simulation results for regenerative braking processes corresponding to three velocity tests are included.
