exhaustemissionsaromaticscontentparticulatesoIn this paper,the influence of aromatic content,one of main fuel properties,on diesel particulate emissions was studied at five steady-state operating conditions using a heavy-duty Perkins 4.236 engine.Detailed analysis of the particulate showed the presence of ...
Depending on operating conditions, engine-out diesel exhaust can contain significant amounts of NO2. Diesel engines using aftertreatment devices with oxidation catalysts (e.g., catalyzed DPFs) have the potential to significantly increase the amount of NO2in the exhaust system downstream of the cataly...

Diesel emissions have a significant impact on the atmosphere, contributing to air pollution, smog and global warming. As a result, diesel exhaust is dangerous to human health. While emissions reduction efforts have often focused on changing engine design or improving aftertreatment, diesel fuel modific...
In this study, regulated and unregulated exhaust emissions with petroleum diesel fuel and Jatropha-based biodiesel blends at proportions of 5%, 10%, 20%, 50% and 100% (v/v) have been investigated. This study examines four regulated emissions: nitrogen oxide, carbon monoxide, unburned hydrocarbon...
The impact of turbocharging on Diesel exhaust emissions has been investigated by studying, on a 4-cyl IDI Fiat engine different configurations including fuel injection optimization, exhaust gas recirculation and oxidant catalysts. The experimental results obtained during bench and chassis dynamometer tests ...
Fuel Consumption and Exhaust Emissions of Diesel, Gasoline and Natural Gas Fuelled Vehicles With regard to increasingly stringent emission legislation natural gas is gaining interest as an alternate fuel. Concerning mobile application natural gas is often considered to produce potentially lower exhaust ...
Several air pollutants comprising PM, e.g., benzo[a]pyrene among other carcinogenic polycyclic aromatic hydrocarbons (c-PAHs) anddiesel engineexhaust emissions, are classified as class-1 carcinogens, whereas gasoline engine exhaust emissions, carbon black, and a number of PAHs are classified as grou...
The usual approach when analyzing alternative fuels impacts on exhaust emissions is by discussing the differing physical and chemical properties of the various blends against those of the reference fuel. Consequently, the composition and properties of biodiesel, together with its combustion and emission ...
The object of this study is to experimentally evaluate a performance and exhaust emissions of a single cylinder, four stroke cycle, direct-injection type diesel engine with no modifications operating on gas oil, waste vegetable oils, waste animal fat from restaurant grease and rice oil methyl ester...
