What is a Direct Injection Engine?

[ONevaeh]

Direct injection engine refers to a gasoline direct injection (GDI) engine, which maximizes the optimization of air-fuel mixture efficiency, resolving the contradiction between high fuel efficiency and high power output. A direct injection engine employs in-cylinder direct injection technology, where fuel is directly injected into the cylinder to mix with the intake air. Direct injection is a type of electronic fuel injection, with its full name being gasoline direct injection. Representative examples of direct injection include Volkswagen's TSI and TFSI, as well as General Motors' SIDI. Compared to traditional electronic fuel injection engines, direct injection engines are more prone to carbon deposits. Vehicle owners should use specialized additives designed for direct injection engines to address carbon deposit issues.
