Automobile engines have undergone tons of changes over the years, primarily to make them more efficient. For the most part though, engine changes result from a string of iterative improvements on ...

Combustion optimisation in direct injection (DI) diesel engines seeks to enhance fuel–air mixing, improve thermal efficiency and mitigate pollutant formation within increasingly stringent ...

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 ...

Gasoline direct injection (GDI) engines have become prevalent in modern light-duty vehicles owing to their improved thermodynamic efficiency and lower fuel consumption compared with ...

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 ...

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 ...

The 5.3-liter V8 Ecotec3 might seem like the stepchild of the General Motors family, especially with the LS series of engines around, but it's a winner in its own right. This naturally aspirated ...

Only years of tough real-world use can truly tell just how reliable an engine is. These are Ford's best.

Carbon buildup can create some big issues while you're driving. A few engine parts are more susceptible to it than others, so ...

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 ...
