Gasoline Direct Injection
Diesel engines vibrates more than a petrol engine due to 1. High compression ratio 2. More ignition timing advance 3. Incorrect valve timing 4.Incorrect combustion chamber 5. Direct injection of diesel on the piston crown 6.Inline Fuel injection pump 7. Type of injectors used and their opening pressure
Gasoline direct injection
Gasoline Direct Injection
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.
Turbo diesel direct injection
Direct Diesel Injection System
Turbo Diesel Injection. NO! it means TURBO DIRECT INJECTION.
Turbo Direct Injection. Usually on diesel powered vehicles.
Complexity and expense
Rudolf Diesel invented the Isobaric Compression engine in 1892, however Herbet Akroyd Stuart did patent a direct injection design two years earlier which was later termed a 'semi-diesel'
Direct injection works somewhat similar to regular fuel injection, but at a MUCH higher PSI. say a non-direct injection car's fuel pressure is anywhere from 40-60SPI, a direct injection fuel pressure runs in the couple of thousands of PSI for gasoline and up to and more than 20,000 PSI for diesel direct injection.the other difference is instead of the injector spraying the fuel into the intake manifold runner (where it has to travel a short distance to the combustion chamber, some fuel doesn't stay as a fine mist, it will stick to the wall of the runner and bead up, like rain on a window) direct injection sprays, you guessed it, DIRECTLY into the combustion chamber. it gives a good boost to compression, which gives you more power and better efficiency
