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 ...

Engine cylinders can misfire due to problems with the ignition system, the fuel system, air and compression, or sensors and ...

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 ...

Cylinder misfires can turn a smooth commute into a rough, fuel‑wasting slog, and they almost always leave a trail of ...

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 ...

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 ...

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 ...
