MPFI ( multi point fuel injection system ) Vs CRDI(Common rail direct injection system)

(Actually an open office format. Use open office to open it)
MPFI : mean multi point fuel injection system ie. in petrol engine for gaining more uniform Air Fuel blending fuel is injected at various point in the path of air. this tech is used in light weight car running on petrol. there is also milage improvement due to this.

but in case of DTSI(digital twin spark ignition) : the
engine cylinder consist of two no of spark plu ....etc

“THE EFFECT OF OXYGEN ENRICHMENT WITH INTAKE AIR IN A DIRECT INJECTION DIESEL ENGINE FUELED WITH COTTONSEED OIL ”
ABSTRACT :-
 With the increasing demand for fossil fuels, a stronger threat to clean environment is being posed as the burning of fossil fuels is associated with dangerous emissions like CO, SOx, NOx and particulate matter, which are currently the dominant global source of emissions.
 These emissions are major causes of air ....etc

Fuel Injection Pressure Effect on Performance of Direct Injection Diesel Engines Based on Experiment
Abstract
Ever increasing rate in the production of fuel injection vehicles and the significance of decreasing the pollutions in nature trigger numerous researches in optimizing the fuel injection system and recognizing the fuel behavior as well as the process of preparation of mixtures in the inlet port of fuel injection vehicles. Fuel injection pressures in diesel engine plays an important role for engine perf ....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
Although current systems relay almost exclusively on mixture formation outside the combustion chamber, concept based on internal mixture formation. With the fuel being injected directly into the combustion chamber were actually the foundation for first gasoline injection system. As there system are superb instruments for achieving further reductions in fuel consumption. There are now becoming an increasingly significant factor.

Fuel Injection in the CI Engine
For the compression ignition engine, it is very important to promote a means of injecting fuel into the cylinder at the proper time in the cycle. This is so because the injection system starts and controls the combustion process.
Objectives of the Injection System
The injection system of the compression ignition engine should fulfil the following objectives consistently and precisely:
Meter the appropriate quantity of fuel, as demanded by the speed of, and the load on, the en ....etc
