Gasoline Direct Injection Service Challenges

Photo Credit: BG Website Fuel injection has been in use for many years because it greatly increases efficiency.  Computer controls direct a precise amount of gasoline to be injected at the moment of the intake stroke.  The amount of fuel depends on information from an array of sensors including engine temperature, ambient temperature, and oxygen levels, for example, along with input from the driver pushing on the accelerator pedal. In the past ten years or so automobile manufacturers have transitioned to “direct injection” fuel injection because it offers more power and reduced emissions.  The main difference between traditional and direct fuel injection is the point of fuel delivery. “Direct” refers to fuel being injected directly into the cylinder immediately prior to the spark which ignites the gasoline instead of the fuel spray being pulled into the cylinder.  That difference means the detergents in the gasoline never come in contact ... read more

GDI: Gasoline Direct Injection Engines

Gasoline Direct Injection = More Power, Better Efficiency!   While it’s true that direct injection engines (GDI) develop more power and produce lower emissions, it is also true that there are some maintenance challenges that have plagued the design for many years.   The evolution from carburetor to fuel injection (which was invented in the 1920’s) took until the 1980’s when virtually all new gasoline powered cars and light trucks were fuel injected.  The move to fuel injection increased fuel efficiency, lowered emissions, and enhanced reliability. Instead of the engine pulling the in the fuel, the system would deliver a precise amount of gasoline at the moment of the intake stroke.   Fuel injection systems can be prone to clogged injectors which led to better gasoline additives and maintenance services designed to “clean” the injectors and fuel intake system.  We recommend an Air Induction service as routine maint ... read more
