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 ...

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 ...

Port fuel injection and direct injection are similar but distinct systems, so why do some engine designs include both?

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 ...

While significant sooty black deposits—and even, occasionally, visible puffs coming from the tailpipe—used to be a sign your gasoline car needed a tune-up, they’re a normal fact of life with many ...

But the industry shift didn’t happen without complications; these new engines have faced three big challenges: chain wear, fuel dilution, and LSPI. In this video we’ll discuss the differences between ...

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 ...

SAE International Journal of Engines, Vol. 13, No. 1 (2020), pp. 77-92 (16 pages) At gasoline direct injection, light-duty engines operated with homogeneous, stoichiometric combustion mode, ...

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 ...
