Opis:
In a conventional internal combustion engine, only electrical controls are used to prepare the fuel mixture. All parts must operate flawlessly in order for the vehicle and its components to operate correctly. Road safety may be negatively impacted by the failure of specific components. The purpose of the study was to ascertain how much the malfunction of particular electrical components affects how the vehicle operates. The vehicle’s individual electronic parts were removed, and the engine power was then assessed. The primary determinant of a vehicle’s technical condition is thought to be its engine power. The preparation of the combustion mixture was affected by the individual component disconnections, which reduced the vehicle’s performance. A vehicle with an in-line four-cylinder engine was used for the experiment, which was conducted in a lab setting. This vehicle’s eight components were gradually disengaged. The change in engine power was observed while they were disconnected. The measured values were always evaluated in terms of an automobile that had no defects and was in excellent condition. The study’s findings demonstrate that there are circumstances in which a vehicle’s usual operation is adversely affected when one or more of its electrical components malfunctions.

Opis:
This study investigated the effect on piston assembly friction after treating piston surfaces with a fine particle bombarding process, using a friction measurement apparatus with a floating cylinder liner, similar to an eco-mileage vehicle engine. Friction was measured in four conditions: (1) no treatment (standard piston in a commercially-available engine), (2) micro dimple treatment (45 μm ceramic particles were air-blasted onto the piston surface), (3) molybdenum disulfide (MoS2) shot treatment (1 μm MoS2 particles were air-blasted onto the piston surface), and (4) combination of the previous two micro dimple and MoS2 shot treatments (first 45 μm ceramic particles and then 1 μm MoS2 were air-blasted onto the piston surface). Results indicated that friction decreased in the following order: no treatment > micro dimple treatment > MoS2 shot treatment > combination of micro dimple and MoS2 shot treatments.

This paper presents an analysis of selected propulsion units dedicated to test stands for unmanned aircraft systems. It focuses on engines suitable for aircraft with a maximum take-off mass up to 150 kg. The study includes an analysis of propulsion units that can be used to power systems on stationary test stands dedicated to advanced research and measurement of prototype aerospace technologies intended for use in rotorcraft. The analysis of propulsion units shows that electric units are a better choice for powering UAV rotorcraft test stands. Their main advantages include the possibility to simplify the construction of the device by eliminating gears and to mount the motor in a vertical position, simpler power supply, cooling and control systems and the lack of an exhaust system. Additional advantages are undoubtedly lower vibration generation, cheaper and easier operation as well as better comfort.

Opis:
The paper presents the possibility of using a VCR engine as a driving unit of a generating set in rail vehicles. Thermodynamic analyzes of the engine were also performed. For the purposes of the research, the piston path was generated in the dynamic simulation in Solidworks to study the processes occurring during the combustion process. This path was used to simulate the AVL Fire program for the same initial conditions. Different variants of the engine cam control with the same compression ratio were compared. The article analyzed the moment and the period of time that the piston remains in the Upper Dead Center (TDC).
W ramach pracy przedstawiono możliwość zastosowania silnika VCR jako jednostki napędowej zespołu prądotwórczego w pojazdach szynowych. Dokonano również analiz termodynamicznych silnika. Na potrzeby badań wygenerowano drogę tłoka w symulacji dynamicznej w programie Solidworks do badania procesów zachodzących podczas procesu spalania. Droga ta została wykorzystana do przeprowadzenia symulacji w programie AVL Fire dla jednakowych warunków początkowych. Porównane zostały różne warianty wysterowania krzywki silnika przy jednakowym stopniu sprężania. W rozpatrywanym artykule analizowano moment oraz okres czasu jaki tłok pozostaje w Górnym Martwym Położeniu (GMP).

Opis:
In this paper, the author presents a study of vibrations in a passenger vehicle and the possible influence on driver’s body in the process of natural operation. The author describes the dependence of engine size and additional equipment as the possible primary source of the vibration variations and their further propagation in the entire vehicle structure. The analysis was performed on the passenger cars with naturally aspirated and turbocharged gasoline engines. The aim of this study was to verify the level of vibrations in the vehicle structure with these particular engines, especially influence of downsized power unit, during various state of engine operation. The second goal was to examine the vibrations in the specified location related to driver’s body. The measuring method used piezoelectric accelerometers, which were attached to the designated locations in the vehicle and were able to detect variations of the acceleration. The signals were collected as characteristics in the time domain. In order to achieve frequency domain for spectral analyses, the author applied the Fast Fourier Transform (FFT).

Opis:
The article deals with the concept, development and results of preliminary tests of a range extender for an electric light commercial vehicle Melex with a 48 V electrical system. The purpose of the project is to build a prototype of the range extender powered by an internal combustion engine that will increase the range of the vehicle with electric drive, and at the same time will be characterized by a high efficiency and low exhaust emissions. The developed range extender is a combination of a 163cc single-cylinder combustion engine with a generator joined through a ribbed belt transmission. The 3-phase generator from a heavy-duty vehicle was used. In order to match the output voltage of the generator to the system voltage of the electric vehicle, an external adjustable regulator and a rectifier bridge with an increased operating voltage were used. The range extender was attached to a body of the electric vehicle by means of a welded frame made of thin-walled steel profiles. Initial tests of the developed range extender showed its proper interaction with both the lead-acid battery of the vehicle as well as with the nickel-metal hydride battery (NiMH) adapted to 48 V voltage from a hybrid electric vehicle. A maximum output power exceeding 2 kW was obtained. Maximum value of the overall efficiency of the range extender reaches up to 18.8%, which is a high value considering the small size of the used engine and the type of generator. The directions for further development of the range extender were also revealed in this paper.

Opis:
Apparatus was developed to measure piston assembly friction with a floating cylinder liner against crank angle, using components of an eco-mileage vehicle engine as much as possible. This apparatus was then used to investigate the effect of different sets of piston rings on piston assembly friction in an eco-mileage vehicle engine. Results indicated that, compared to the piston with all three rings (a top ring, a second ring and an oil ring), the piston with two rings (a top ring and an oil ring) reduced piston assembly friction at all engine temperatures and engine speeds. Another configuration of two rings, with the top ring and the second ring, but without the oil ring, reduced friction at a lower engine temperature and speed, but was almost the same as the three-ring set at a higher engine temperature and speed. Finally, a one-ring set, with only the top ring, further reduced friction, except at a higher temperature and speed, where friction was greater than the two-ring set without the second ring.

Opis:
One of the ways to reduce exhaust emissions from vehicles is to replace worn-out shunting locomotives with road-rail tractors. The main purpose of this solution is to reduce the negative environmental impact of the vehicle and to reduce the fuel consumption compared to a shunting locomotive performing the same work. The tests on exhaust emissions of rail vehicles are carried out on an engine test bench, making it impossible to determine the environmental performance of these vehicles during real operation. Therefore, it is advisable to carry out measurements in real operating conditions in order to obtain reliable reference results. This enables the verification of vehicles ecological indicators in a wide range of operational work parameters. It is possible to obtain reliable results regarding the impact of the tested vehicle on the natural environment in this way and compare them with the applicable emission standards.

Opis:
Hydrocarbons, especially aromatic volatile organic compounds (AVOCs) and polyaromatic hydrocarbons (PAHs), emitted by IC engines, indisputably have a negative impact on the environment and public health. Even though current legislation strongly impacts on their low concentration in the exhausts, not quantity but the quality of those substances determines fumes toxicity. The paper presents results of the researches on a photocatalytic device dedicated to BTX (benzene-toluene-xylene) removal from IC engine exhausts, which can be applied in a vehicle cabin ventilation system. According to the results, the system is able to decrease toxic compounds concentration (caused by mobile emission sources) in inlet-air delivered to the vehicle interior. In effect, the system application reduces the users of a vehicle to exposure on contaminants.

This paper presents a study of vibrations appearing in a vehicle in the process of its operation. The authors describe the primary source of the vibrations and their propagation in the entire structure. The observations were performed on the passenger cars with various gasoline and diesel engines. The aim was to examine the level of damping factor in the different locations in the car, precisely specified for the purpose of this studies. The secondary goal was to develop an effective method of obtaining and analyzing signals generated during the engine operation. The chosen instrument was Laser Doppler Vibrometer (LDV), which is used as the non-intrusive measurement utensil to detect velocity variations in designated places. The signals are gathered and collected as group of sinusoidal characteristics in the time domain. In order to achieve specific information about every component of the original signal, the authors apply Fast Fourier Transform (FFT) as the analyzing method. It allows to distinct the basic sinusoidal characteristics in the frequency domain through the spectral analysis. Based on the results, the authors are able to distinguish the dominant modes from the complex signal and indicate their impact on the car.

The main objective of the research presented in this paper is to enhance driver-passengers Comfort of a vehicle that in turn leads to better vehicle safety and stability. The focus was put on studying the interior vibration and noise contributions originated from tire-road and engine-transmission subsystems, due to their significant impact on the dynamic performance of the vehicle. The noise and vibration measurements were recorded at the driver’s head position and on the driver legs room. Furthermore, the influence of different tire types and road surface textures on the vehicle interior noise and vibration were considered. The results indicate that the widely used conventional engine mounts and tires in commercial vehicles cannot fulfill the conflicting requirements for the best isolation concerning both road surface and engine-transmission induced excitations. The values of driver’s head position sound pressure level and floor vibration acceleration broadband averages originate for engine-transmission are lower than that for tire-road interaction. Furthermore, the values of RMS, crest factor, kurtosis and IRI for the vehicle waveform were estimated for vehicle speeds, tire types and road surface textures. Moreover, the percentage contribution for both interior noise and vibration originated from tire-road interaction is higher than the one from vehicle engine-transmission system in all the vehicle speed range, tire type and road surface texture considered.

Opis:
The use of electrically powered vehicles is becoming more and more established in practice and represents a promising solution in future ensuring quality mobility and reducing the pollution in the environment. Since these vehicles are high-priced, and there is still a low awareness among consumers in terms of energy consumption and pollution, vehicles with an internal combustion engine remain the norm. For this purpose, the study, here, provides an energy consumption estimate of an electric vehicle and thus its carbon footprint and compares it to the energy consumption and carbon footprint of a vehicle with an internal combustion engine. The results of this study reveal the orientation for the use of electric vehicles in future, in terms of raising awareness among the individual manufacturers, consumers and, last but not the least, the society as a whole, which is committed to sustainable developmental orientations.
