INTRODUCTION
In recent years, legislative and market requirements have driven the need to reduce fuel consumption while meeting increasingly stringent exhaust emissions. This trend has dictated increasing complexity in automotive engines and new approaches to engine design. A key research objective for the automotive engineering community has been the potential combination of gasoline-engine specific power with diesel-like engine efficiency in a cost-competitive, production-feasible power train. One prom ....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

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.

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

Abstract
The development of four-stroke, spark-ignition engines that are designed to inject gasoline directly into the combustion
chamber is an important worldwide initiative of the automotive industry. The thermodynamic potential of such engines for
significantly enhanced fuel economy, transient response and cold-start hydrocarbon emission levels has led to a large number of
research and development projects that have the goal of understanding, developing and optimizing gasoline direct-injection
(GDI) combustion systems. The proces ....etc

The gasoline-powered internal combustion engine has seen more improvement in the last five years than in the last twenty, Quieter timing chain technology, direct fuel injection, and variable intake and exhaust valve timing, among others, have led to better fuel efficiency and reduced emissions.

Everyone knows that, in the case of a gasoline-powered ICE, three things are needed, compressed air, fuel, and spark, which are facilitated by, respectively, the crank and pistons, the injection system, and the ignition system.

By eliminating ....etc

Gasoline direct injection or GDI is a variant of fuel injection employed in modern four stroke petrol engines. The gasoline or biobutanol is injected right into the combustion chamber of each cylinder, as opposed to conventional multi point fuel injection that happens in the intake manifold.

GDI enables stratified charge (ultra lean burn) combustion for improved fuel efficiency and emission levels at low load. Further improving efficiency and high-load output-power, the engine power is governed by modulating fuel injection, like a diesel eng ....etc
