1. INTRODUCTION
Petrol vehicles uses device called carburetor for supplying the air fuel mixture in correct ratio to cylinders in all rpm ranges. due to construction of the carburetor is relatively simple, it has been used almost exclusively on gasoline engines in the past. However in response to recent demands for cleaner exhaust emission, more economical fuel consumption, improved drivability, etc., the carburetor now must be equipped with various compensating devices, making it more complex system. ....etc

INTRODUCTION
A multi-point injection system, also called port injection, has an injector in the port (air-fuel passage) going to each cylinder. Gasoline is sprayed into each intake port and toward each intake valve. Thereby, the term multi-point (more than one location) fuel injection is used. Multipoint fuel injection (MFI) locates an injector immediately upstream of each inlet valve, which enables better control of the air/fuel mixture to each cylinder.

INTRODUCTION
You must have seen cars with specifications which mention words like MPFI and CRDI or CRDE. To an automotive engineer or enthusiast, it means something, but for a common man, it may not make much sense.
MPFI means – Multi-point Fuel-Injection


The term MPFI is used to specify a technology used in Gasoline/petrol Engines. For Diesel Engines, there is a similar technology called CRDI. MPFI System is a system which uses a small computer to control the Car’s Engine. A Petrol car’s engine u ....etc

Internal combustion engine
The internal combustion engine is an engine in which the combustion of a fuel (generally, fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber. The expansion of high temperature and pressure gases produced by the combustion applies force to a movable component of the engine(piston, turbine blade etc.) moves it over a distance, generates useful mechanical energy.

The major advantages of a GDI engine are increased fuel efficiency and hi ....etc

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 pr ....etc

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.
