Direct-injected engines helped modern vehicles produce better fuel economy and stronger performance, but mechanics are ...

Direct injection engines deliver fuel at high pressure directly into the combustion chamber. When the fuel spray strikes surfaces such as the piston crown or liner, a thin liquid film forms. This film ...

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 ...

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

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 ...

Three and a half years of engineering have brought this beast to life with direct injection, variable valve timing, and way ...

Direct injection systems, in which a high-pressure fuel pump pressurizes the fuel for injection directly into the cylinder by an injector, provide greater freedom in the injection timing and volume ...

Turns out the old technology did a few things no computer has matched.

Knowing the inner workings of a vehicle comes with its set of benefits. You know the risks associated with potential issues, understand the causes, and can quickly fix things DIY-style. It is ...
