sidi means Spark Ignition Direct Injection
SIDI in automotive, stands for "Spark-Ignition Direct-Injection" which is a type engine by GM. An example is Cadillac CTS 3.6 SIDI. It produces more horsepower and torque than a PFI engine (Port Fuel Injection).
Gasoline direct injection
Turbo diesel direct injection
CRDI is an abbreviation for common rail direct fuel injection. This is a direct fuel injection system that is used in diesel and petrol engines.
CGI stands for Charged Gasoline Injection, which means the model's engine uses direct injection.
Fuel Stratisfied Injection. It uses gas more efficiently and economically by direct injection into the engine.
It refers to the type of fuel injection system, in this case High-pressure Direct Injection.
both are same technologies ...CRDI is Common rail DIRECT INJECTION
FSI or Fuel Stratified Injection is another term for Direct Injection where the fuel is injected directly into the cylinder instead of the intake tract.
FSI stands for Fuel Stratified Injection, which describes the stratified petrol direct injection attained by this engine designed by Volkswagen.
crdi means common rail direct injection system there will e a rail(straight pipe) structure in that fuel wil pass into that there is an another method "dicor" direct injection common rail
TDI means Turbocharged Direct Injection. The important part is the "DI"--Direct Injection. There is an Indirect Injection. With it, the fuel is injected into a low-pressure prechamber where it starts burning before it enters the combustion chamber. In Direct Injection, the car shoves fuel into the combustion chamber itself at well over 10,000 psi. This gives much better efficiency.
