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 ...

Compression ignition basically is the term that is used for describing the manner in which diesel engines function. It happens when intake air—which often is combined with recirculating exhaust gas—is ...

Performance diesel engines are usually the realm of European automakers, but the highest-revving diesel actually comes from ...

You probably know how diesel engines work, but it's one thing to understand the theory and a whole different thing to ...

Any certified gearhead knows that diesel engines do not use spark plugs. But why not? If power in an engine is created by combustion or explosion of flammable liquids, won't a spark plug in a diesel ...

In the race to field energy-efficient vehicles, don’t count out internal combustion technology just yet. GM recently debuted its homogeneous-charge-compression-ignition (HCCI) system in two drivable ...

Hydrogen offers a compelling pathway to decarbonise compression-ignition (CI) engines by leveraging its high energy density, wide flammability limits and rapid flame propagation. In conventional ...

Some engine designs fade into the background, quietly doing their job until regulations or fashion move on. Others keep ...

The automotive industry continues to be a hotbed of innovation, with activity driven by factors such as auto-ignition properties of the fuel, fuel concentration, and residual rate, and growing ...

What's the secret to diesel engines usually lasting longer than their gasoline-powered counterparts? To some extent, it comes ...

With every passing day the Mule provides opportunities beyond our original expectations. Since the 467ci engine belongs to HPP editor Tom DeMauro, it is at our beck and call. This affords HPP the ...
