Over time and miles, your car might start to slow down. It might not accelerate as quickly as it once did; the engine may not run as smoothly as you remember, or the fuel economy may dip—but ...

Gasoline direct injection, or GDI, is one of the most crucial bits of technology in the modern internal combustion engine. In engines equipped with GDI, highly pressurized gasoline is sprayed directly ...

Over time and miles, your car might start to slow down. It might not accelerate as quickly as it once did; the engine may not run as smoothly as you remember, or the fuel economy may dip—but ...

Gasoline direct injection (DI) engines have been lurking in the shadows of gasoline-burning, internal combustion engine development for decades but are now becoming mainstream. This is all good, as DI ...

Fuel injectors certainly can suffer from a build-up of carbon and the problem will be worse if the engine is not burning its fuel and air completely every time its cylinders fire. But 58,000km would ...

Most new petrol cars you see today are equipped with fuel injection systems or injector motors. These have almost wholly supplanted older carburetor motors. They are more reliable, effective, and ...

Times are a-changin’, folks. 2010 was twelve years ago, and a lot of the affordable used performance cars available today are more technologically advanced than ever. And none of those technologies ...

Port fuel injection (PFI) was a major milestone in the early '80s. The integration of PFI rapidly changed the way fuel was delivered by increasing fuel economy and improving engine performance. Even ...

The fuel injection pressures used in gasoline direct injection (GDI) engines have increased in recent years to improve fuel efficiency and reduce emissions. Current GDI engines use injection pressures ...
