A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

If your vehicle has been running roughly or seems to be losing power, it's possible that there's a lack of pressure in one or more of the cylinders. Without enough pressure, the fuel/air mixture doesn ...

Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...

Whereas up until now the automotive enthusiast knew of roughly only two large scale-use engines, the gasoline and the diesel, technological developments and new requirements imposed by economical or ...

Homogeneous charge compression ignition (HCCI) engines combine a diesel's torque and fuel efficiency with a gas engine's cleaner emissions. The HCCI technique has been a goal of automakers since the ...

What many consider the Holy Grail of combustion technology is one step closer to prime time. In the race to field energy-efficient vehicles, don’t count out internal combustion technology just yet. GM ...

We're always looking for ways to make more power without spending too much money. We bolt on carburetors and intake manifolds. We also perform cam swaps in our quest for power. When that doesn't meet ...
