Emissions from automobiles vehicles are already a big part of the environmental pollution
that seriously affects the symmetrical nature of the atmosphere. Vehicle emissions contribute …

Diesel engine emissions are typically composed of several hundred chemical compounds,
partly present in the gas phase and partly in solid phase as particles, the so-called …

This paper discusses the determination of fuel consumption and exhaust gas emissions
when shredding branches in urban areas. It aimed to determine the hourly emission of …

A mixture of diesel, biodiesel (from algae), and butanol was mixed with nano-titanium
dioxide at 50 and 100 parts per million in this study under post-injection (PI) strategy and two …

All modern diesel vehicles in Europe are equipped with diesel particulate filters (DPFs) and
their particle number (PN) emissions at the tailpipe are close to ambient air levels. After the …

The air pressure change as a function of the driving altitude affects negatively the engine
performance and emissions as well as the efficiency of the exhaust aftertreatment systems …

Limits imposed by worldwide emission regulations on particulate emission from diesel
engine exhaust resulted in the employment of filters to cut down pollutants to acceptable …

Internal combustion engines working at cold conditions lead to the production of excessive
pollutant emissions levels. The use of the exhaust gas recirculation could be necessary to …

Worldwide emission standards are extending their requirements to cover engine operation
under extreme ambient conditions and fill the gap between the type-approval and real …

In diesel engines, post fuel is injected in the expansion stroke, oxidized by the diesel
oxidation catalysts and the high temperature gas re-generates the diesel particulate filters …
