compression ignition engine emission
Opis:: The volatile organic compounds (VOC's) are significant group o air pollution emitted during fuel combustion in diesel engines. This research work is continuation of research where the influence of an inert catalyst on toxic emission from a self-ignition engine has been investigated. In particular volatile organic compounds VOC's emissions which are known to have mutagenic and carcinogenic properties, have been studied. The experimental results show that implementation of catalytic coating on chosen elements of diesel engine causes change of percentage participation of particular compounds in their sum and decrease of their concentration. The analysis of chosen compounds (benzene and formaldehyde) shows that the modification which was proposed causes increase of concentration of those substances when engine works in specific conditions, what is connected with change of engine exhaust toxicity and decrease in PAHs concentration, what is connected with toxicity decrease in exhaust gases. In particularly research work stand, the comparison of total VOC's concentration with and without catalytic coating, the comparison of benzene concentration, the comparison of formaldehyde concentration, the comparison of toxicity level with and without catalytic coating are presented in the paper.

Opis:: The inner atmosphere of a car vehicle became one of the most important environments of human life. Many elements inside of a car cabin are potential sources ofvolatile organic compounds (VOC's) which hazardous effect on human health is proved. To estimate quality of indoor air of a car the qualitative analysis of hydrocarbons is very important considering the fact that some substances (i.e. benzene, acetone and xylene isomers) despite low concentration level characterize toxic and carcinogenic properties. A significant impact on VOC's concentration has vehicle cabin eąuipment and quality of applied materials. The internal sources of the pollution are elements of cabin equipment (textiles, foams, plastic materials), solvents in glues, paints, lacąuers and car cosmetics. The external sources of the pollution are pollutants emitted to environment in gas phase by mobile or static sources. This paper presents the results of the research which aim was qualitative and quantitative analysis of VOC's concentration inside of various classes of car vehicle cabins. The research was done in Emission Research Laboratory of the Division of Motor vehicles and Internal Combustion Engines. The analysis was done according to European standard (EN ISO 16017-1: 2006) on gas chromatograph (Varian 450 GC) eąuipped in capillary column and flame-ionization detector (FID). Keywords: Volatile hydrocarbons, indoor measurements, car vehicle cabin.

Opis:: The new passenger car, BMW 225 XE was tested. The results of measurements of concentration of VOCs carried out inside the car cabin depending on the temperature were presented. The investigation was carried out in a special climatic chamber isolated from external factors such as outside air pollutants and weather conditions. The following temperature values have been set: 17ºC, 20ºC, 35ºC and 50ºC. The samples were located inside and outside of the vehicle’s cabin. As expected, the concentrations of each compound increased with increasing temperature (volatility of VOCs increases with the temperature). Values of concentrations obtained in the measurements have been compared with the values of highest acceptable concentration specified in polish law. The article describes the investigation, which was provided in a special climatic chamber. The chamber was isolated from external weather conditions and pollutants. Before each sampling interior of car cabin was ventilated to remove all pollutants from inside. Concentrations of BTX measured in different temperatures were converted to temperature of 20ºC.

Opis:: Nowadays, with the current dynamic development of the automotive industry, we spend more and more time indoors, including in vehicles. The air used for ventilation of the vehicle's cabin comes from the outside. Pollution enters into the vehicle. This research presents the results of tests conducted to assess the exposure of the driver and passengers to volatile organic compounds entering the vehicle with atmospheric air. The simulation researches were conducted on a chassis dynamometer at the Department of Vehicle Engineering at the Faculty of Mechanical Engineering Technical University of Wroclaw and the tests under real conditions, i.e. traffic urban conditions, were taken as well. The measurements were conducted in the centre of Wroclaw during peak hours, when the traffic jam is the most frequent. The measurements were taken in order to organic compounds analysis, which includes gas chromatography. The analysis results were averaged from three measurements to get these studies more reliable. Results show that during mobile tests the vehicle was exposed to much more pollution than in the stationary tests in the simulated conditions of traffic congestion. Therefore, the studies present that the pollution in the traffic congestion is the real danger to drivers.
