What is GDI

Engine manufacturers are switching to Direct Injection Fuel Injectors to meet emissions standards, better performance and greater fuel economy. GDI or Gasoline Direct Injection is a process where the a very fine mist of fuel is injected, at fuel pressures that vary between 450—3000 psi, directly in to the combustion chamber. To achieve these pressures, the gasoline is pressurized by a high pressure fuel pump that is mechanically driven and electronically controlled.

Because there is no cleaning agent, such as gasoline, present to clean the valves from any debris, carbon and dirt builds up behind the intake valves and ports. After 45000 miles, engines start losing performance and its costly to fix because you’ll need to remove the cylinder head to remove the dirt buildup from the intake valves and ports.

  • FSI = VW Audi ( Fuel Stratified Injection)
  • SCi = Ford (Smart Charge Injection)
  • IDE = Renault (Injection Direct Essence)
  • JTS = Alfa Romeo (Jet Thrust Stoichiometric)
  • SIDI = Holden (Spark Ignition Direct Injection)
  • HPI = BMW (High Precision Injection)
  • HPDI = Porsche (High Pressure Direct Injection)
  • Ecotec = GM, Vauxhall, Opel
  • CGI = Mercedes Benz (Charged Gasoline Injection)
  • DISI = Ford/Mazda (Direct-Injection-Spark-Ignition)
