ABSTRACT
Engine is one of the most important and costliest part/system of a vehicle, which acts like a heart of the human being, so, we have to keep it in always good condition.
It consumes around 55% of operating cost of the vehicle, due to which we have to concentrate more on ....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
Homogeneous charge compression ignition (HCCI) is a form of internal combustion in which well-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. Homogeneous charge compression ignition (HCCI) engines have
the potential for high efficiencies and low pollutant emissions.By comparison with spark ignition (SI) engines, for example,HCCI engines can yield a 15-20% increase in fuel economy while emitting lower levels of oxides of nitrogen (NOx).HCCI engines can also achieve thermal eff ....etc

Progress and Recent Trends in Homogeneous Charge CompressionIgnition (HCCI) Engines
What Is HCCI?
An HCCI engine is a mix of both conventional spark-ignition and diesel compression ignition technology.
HCCI is characterized by the fact that the fuel and air are mixed before combustion starts and the mixture auto-ignites as a result of the temperature increase in the compression stroke.
The resulting spontaneous burn produces a flameless energy release in a large zone almost simultaneously -- very different th ....etc
