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 ...
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 ...
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 ...
A teardown of Honda’s R18 engine suggests that added complexity in modern powertrains may come at the expense of long-term ...
Port fuel injection and direct injection are similar but distinct systems, so why do some engine designs include both?
The power, fuel efficiency, and longevity of an engine will heavily depend on the fuel that’s being delivered. Furthermore, ...
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 ...
The fuel injection pressures used in gasoline direct injection (GDI) engines have increased in recent years to improve fuel efficiency and reduce emissions. Current GDI engines use injection pressures ...
