MPFI is Multi-Point Fuel Injection, which is the fuel system used with gasoline engines. CRDI is Common Rail Direct Injection, which is the fuel system used in diesel engines.
There is no difference. Petrol is just another name for gasoline. MPFI just means Multi-Point Fuel Injection. A petrol (gasoline) engine can be MPFI or it can have a carburetor. It can have many different ways to get gasoline (petrol) to the cylinders.
it spilts the fuel into vapour under high constant pressure mpfi stans for it ejects the fuel into each cylinder
CRDi
crdi gives more mileage
MPFI= Multi Port Fuel Injection
Frederick William lanchester invented the earliest MPFI engine
both are same technologies ...CRDI is Common rail DIRECT INJECTION
PREMIER AUTOMOBILES LIMITED, INDIA HAS INVENTED THE FIRST CRDi DIESEL ENGINE CRDI FUEL PUMP WAS INVENTED BY BOSCH, GERMANY. Answer by Soney Thomas
DICOR is nothin but refurbished term for crdi and it stands for "Direct Injection Common Rail engine" and the simple funda of crdi is a modern variant of direct injection system for diesel engines. It features a high-pressure (1000+ bar) fuel rail feeding individual solenoid valves, as opposed to low-pressure fuel pump feeding pump nozzles or high-pressure fuel line to mechanical valves controlled by cams on the camshaft. and yeah crdi and dicor is for diesel engines....where as mpfi (multiple point fuel injection) is for petrol engines and if we talk in layman language when we used carburettor fed engine.....the main problem was that the fuel air mixture was not uniform in all the cylinders. it was always that the first chamber got the richest mixture and the last chamber got the lean mixture so to get rid of this problem the engineers developed a system where we injected the fuel rather than m ixing it with air and just air was sucked in the suction stroke. i hope this would help Regards Punit
A CRDI, which is also known as a Common Rail Direct Injection Engine is used with engines which use diesel fuel. The function of the CRDI is similar to a regular engine with the utilization of modern computer systems. The CRDI is known for reduced emission release as well as better performance.
The first MPFI technology is believed to have been invented in 1925 by Jonas Hesselman. MPFI technology refers to Multi Point Fuel Injection systems.
