abstract
An opposed-piston hydraulic free piston engine operating with homogenous charge compression ignition (HCCI) combustion, has been proposed by State Key Laboratory of Engines as a means of significantly improving the IC engine s cycle thermal efficiency and lowering exhaust emissions. Single and multi-zone Chemkin model with detailed chemical kinetics, and unique piston dynamics extracted from one dimensional gas dynamic model, have been used to analyze the combustion characteristics and engine performance. Intake heating, vari ....etc

Abstract

-In this paper, a combustion simulation model for a 4-stroke, direct injection diesel engine is described.
- The combustion modeling was based on the assumption that the combustion process was taken to be only a heat addition process and the in-cylinder conditions are spatially uniform. as the heat release model, the well known wiebe s combustion function and the white house-way s heat release model were studied and successfully employed to the combustion simulation
- A comparison has been m ....etc

ABSTRACT
Combustion chamber deposits are found in all internal combustion engines. When fuel and air burn inside an internal combustion engine, deposits form on the walls inside the cylinder. The factors influencing deposit formation are changes in fuel composition, coolant temperatures, engine speed and load, and spark timing. One way to discourage deposit formation is to prevent condensation. Raising the wall temperature prevent condensation. With increased wall temperature, hydrocarbon condensation te ....etc

ANALYSIS OF CATALYTIC COATING IN THE COMBUSTION CHAMBER IN FOUR STROKE ENGINES

ABSTRACT:


The analysis of catalytic coating in the combustion chamber in four

stroke engine is done in order to improve the performance of the vehicle and also to

reduce the percentage of harmful pollutants in the exhaust gas. In four stroke engines,

the combustion chamber is modified by applying catalytic coating means of

electroplating. Catalytic materials are used in order to provide minimize the pollutant

content in the exhaust an ....etc
