If you think direct-injection diesel engines made their debut in the 1980's, think again. The first diesel without extra ...

Port fuel injection has some big advantages, but automakers increasingly are using gasoline direct injection instead. The ...

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 ...

The basic difference between direct injection (DI) and the port-fuel injection (PFI) systems we've become familiar with since the mid-1980s is that PFI sprays fuel into the intake manifold (behind ...

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 ...

Turbo Fuel Stratified Injection technology for gasoline engines was once a remarkable innovation that has since become quite commonplace. Traditional fuel-injected engines that don't use direct ...

There are numerous differences between diesel and gas engines, including the number of fuel filters each uses. Here's why ...

Filed in April 2019 then published by the USPTO yesterday, the patent titled “high-performance internal combustion engine with improved handling of emission and method of controlling such engine” is ...

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 ...

These 3-cylinder engines have proven themselves in Hondas, BMWs, Toyotas, and even Koenigseggs, delivering performance and ...
