HCCI has characteristics of the two most popular forms of combustion used in IC engines: homogeneous charge spark ignition (gasoline engines) and stratified charge compression ignition (diesel engines). As in homogeneous charge spark ignition, the fuel and oxidizer are mixed together. However, rather than using an electric discharge to ignite a portion of the mixture, the concentration and temperature of the mixture are raised by compression until the entire mixture reacts spontaneously. Stratified charge compres ....etc

seminor ppt on new concept of homogeneous combustion in i c engines using the porous medium combustion engine

The paper summarizes the knowledge concerning porous media combustion techniques as applied in engines. One of most important reasons of this review is to introduce this still not well known technology to researchers doing with internal combustion engine processes, thermal engines, reactor thermodynamics, combustion, and material science. The paper gives an overview of possible applications of a highly porous open cell structures to in ....etc

Hello,
I am looking for matter on a seminar titled Lean Burn Spark Ignition Engines on your website. It is possible to view a small abstract of this seminars, but I somehow cannot obtain the entire matter. I require this very urgently. Please do let me know if I can get access to the complete seminars.

Thank you,

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

Lean-burn refers to the burning of fuel with an excess of air in an internal combustion engine. In lean-burn engines the air:fuel ratio may be as lean as 65:1 (by mass). The air / fuel ratio needed to stoichiometrically combust gasoline, by contrast, is 14.64:1. The excess of air in a lean-burn engine combusts more of the fuel and emits fewer hydrocarbons. High air fuel ratios can also be used to reduce losses caused by other engine power management systems such as throttling losses.
A lean burn mode is a way to reduce throttling losses. An e ....etc

ABSTRACT
Laser ignition has become an active research topic in recent years because it has the potential to replace the conventional electric spark plugs in engines Compared to conventional spark ignition. Laser ignition allows more flexible choice of the ignition location inside the combustion chamber with the possibility to ignite even inside the fuel spray .Modern engines are required to operate under much higher compression ratios, faster compression rates, and much leaner fuel-to-air ratios than gas engines toda ....etc

ABSTRACT
A high-frequency electrical resonance-based ignition concept
is in development to replace conventional spark ignition
functionality for gasoline engines employing various types of
fuel injection methods. The concept provides the benefit of a
continuous discharge phase and the electrical power of the
discharge can also be adjusted to the needs of the combustion
conditions.
This concept employs an alternative method of generating
high voltages, using inductors and capacitors trimmed such
that the supplied energy steadily ....etc

HEAT RELEASE:

Rate at which the chemical energy of the fuel is released by the combustion process.

It can be calculated from cylinder pressure versus crank angle data, as the energy release required to create the measured pressure, using the known techniques.

Spray structure:

The fuel is introduced into the combustion chamber thro one or more nozzles or orifices with large pressure difference between fuel supply line and cylinder.
Std diesel inj ....etc
