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 ...

Automakers have long touted the benefits of fuel injection, claiming increased efficiency and power. But as more cars have the system installed (around 73% in 2023), more and more consumers are ...

Direct-injected engines helped modern vehicles produce better fuel economy and stronger performance, but mechanics are increasingly warning that carbon buildup has become a serious long-term ...

The power, fuel efficiency, and longevity of an engine will heavily depend on the fuel that’s being delivered. Furthermore, ...

Anyone who has gone to school to learn how to repair engines of all types, such as myself, will have learned the fundamentals of how they work. It's crucial for troubleshooting and diagnosing engine ...

The study reveals the mechanisms behind wall film formation, a key contributor to particulate matter emissions under cold fuel conditions The growing concerns about air pollution and its harmful ...

The other day I dropped my car off at a European specialist shop, and while I was there, a technician was working in the engine bay of a Mk7 Golf R, cleaning out carbon deposits off the intake valves.

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 ...

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 ...

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 ...

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 ...
