Mechanism of smokeless diesel combustion with oxygenated fuels based on the dependence of the equivalence ration and temperature on soot particle formation
free download

The equivalence ratio F and temperature T are well known to have a significant effect on the quality of particulate formation, such as the soot volume fraction, particle diameter and number density. The purpose of this work is to clarify the F-T dependence of soot 

Emissions suppression mechanism of premixed diesel combustion with variable valve timing
free download

A variable valve timing (VVT) mechanism is applied to achieve premixed diesel combustion at higher load for low emissions and high thermal efficiency in a light-duty diesel engine. By means of late intake valve closing (LIVC), compressed gas temperatures near the top 

DeNO x mechanism caused by thermal cracking hydrocarbons in the stratified rich zone duringdiesel combustion
free download

This study concerns an experimental and theoretical investigation of the deNO x mechanism caused by thermal cracking hydrocarbons during diesel combustion. A total gas sampling experiment using a rapid compression machine showed that NO x can be reduced under 

Revisit of Diesel Reference Fuel (n-Heptane) Mechanism Applied to Multidimensional DieselIgnition and Combustion Simulations

ABSTRACT Two reduced n-heptane mechanisms, previously developed in 1998 (40 species and 165 reactions) and in 2000 (65 species and 273 reactions) respectively, were revisited and the mechanism improvement was pursued. In the newly revised version, the 

Validation of a grid independent spray model and fuel chemistry mechanism for low temperaturediesel combustion
free download

Spray and combustion submodels used in a Computational Fluid Dynamics (CFD) code, KIVA-CHEMKIN, were validated for Low Temperature Combustion (LTC) in a diesel engine by comparing measured and model predicted fuel spray penetrations, and in-cylinder 

DIESEL ENGINES WITH NEW FUEL-AIR MIXTURE FORMATION AND COMBUSTION MECHANISM
free download

ABSTRACT One of the most difficult problems to be resolved during the development of diesel engines is to decrease nitrogen oxides, soot (smoke) and particulates in exhaust emissions, without decreasing performance and efficiency, to limits proposed by emission standards, 

Diesel Fuel Surrogate Oxidation Mechanism with Application to Spray Combustion Modelling
free download

ABSTRACT A numerical study has been carried out on the application of a detailed chemistry mechanism for diesel fuel surrogate to spray combustion modelling. The fuel surrogate vapour is represented by a mixture of 70% n-heptane and 30% toluene and is
