Common rail direct fuel injection is a direct fuel injection system for petrol and diesel engines.

On diesel engines, it features a high-pressure (over 1,000 bar or 100 MPa or 15,000 psi) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). Third-generation common rail diesels now feature piezoelectric injectors for increased precision, with fuel pressures up to 3,000 bar (300 MPa; 44,000 psi).

In petrol engines, it is used in Gasoline direct ....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.

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

ABSTRACT
Compared with petrol, diesel is the lower quality product of petroleum family. Diesel particles are larger and heavier than petrol, thus more difficult to pulverize. Imperfect pulverization leads to more unburnt particles, hence more pollutant, lower fuel efficiency
and less power.
Common-rail technology is intended to improve the pulverization process. Conventional direct injection diesel engines must repeatedly generate fuel pressure for each injection. But in the CRDI engines the pressure i ....etc

The world is surely and steadily moving towards the newer generation of direction injection diesels, be it unit injected or common-railed. Mercedes Benz had already introduced the common rail engine in India a few years back but then they are the technology leaders worldwide and augur no comparisons. so. it was a matter of time before one of the other car manufacturers in India took up the challenge and introduced the engine in a car that could be available to a much larger segment of the car-buying populace.

As it has done on a number of ....etc

COMMON RAIL DIRECT INJECTION (CRDi) AS A POWER GENERATING UNIT IN AUTOMOTIVE SYSTEM


INTRODUCTION
While the Japanese are leading in petrol direct injection technology, Germany's Bosch, working in conjunction with several European car makers, Have pioneered Common-Rail Direct Injection for diesel engines. Compared with petrol, diesel is the lower quality ingredient of petroleum family. Diesel particles are larger and heavier than petrol, thus more difficult to pulverize. Imperfect ....etc
