What does Mercedes-Benz CGI mean?
1 Answers
Mercedes-Benz CGI stands for the following: 1. Introduction: CGI stands for Stratified-Charged-Gasoline-Injection, which is a stratified gasoline direct injection technology. 2. Technology: The engine CGI technology completely separates the fuel supply action from the intake valve and piston system, giving the ECU more control. This enables ultra-lean combustion beyond traditional injection theory and more diverse air-fuel ratios. 3. Effect: During stable driving or low-load conditions, engines with in-cylinder direct injection design can enter the Ultralean mode. In this setting, the engine only draws in air during the intake stroke, while the fuel injector supplies fuel during the compression stroke to achieve fuel-saving effects.
