The dynamic development of the automotive industry makes the consumption of diesel oil grow rapidly. Due to the increasing ecological requirements, research is conducted that aims at the reduction of the negative influence of this branch of industry on the environment. One line of research is the search for ecological fuels, such as dimethyl ether. The application of this fuel with a simultaneous...
The article describes the impact of toxic components of exhaust gases on the environmental pollution and the resulting problems that have a direct impact on human health. It presents the legal regulations in force in the European Union which oblige vehicle manufacturers not to exceed the limit values for emissions of toxic exhaust components. It shows the influence of the motor vehicle speed on the...
The article presents the particulate matter measurement analysis of a passenger vehicle equipped with diesel particulate filter in real operating conditions. The tests were conducted in the Poznań urban agglomeration on routes with variable speed limits. The procedure included two different driving styles – aggressive and normal. The measurement of particulate matter included their mass, surface area,...
The article discusses the subject of light duty vehicles exhaust emissions in real driving conditions and their connection with fuel consumption. Tests were carried out in the Poznan agglomeration area on roads with various speed limits. The driver was to drive the same distance first driving in an aggressive manner than normally. Emissions of the following compounds were measured using a SEMTECH...
This article presents a comparison of CO2, CO and NOx emission from Saab 9-3 1.9 JTD and Fiat Bravo 2.0 JTD engines. The tests were conducted on the same route and reflect real driving emission from following passenger cars. Fiat Bravo engine is an evolution of 1.9 engine redeveloped to meet EURO 5 requirements. Despite cylinder diameter enlargement and increased fuel consumption harmful exhaust gases...
Non-road vehicles are a large group of machines and a vast majority of them utilize CI engines. This group includes agricultural vehicles, construction machinery, stationary engines, etc. Their regulations are less restrictive compared to vehicles from the HDV category which use similar engine units. For this reason, the Stage V standard will be introduced in 2018, adding reductions in the form of...
