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 ...

In response to stricter global emissions standards, automakers are looking for new ways to wring every last bit of efficiency out of the internal-combustion engine. In this Engineering Explained video ...

Can Entry Ignition Save Combustion Engines? New Efficient Technology! How do Entry Ignition (EI) engines overcome the biggest flaws of combustion engines? We know that Spark Ignition (SI) engines are ...

Rotary engines differ from conventional ones in many respects — and one of them is the fact that they use two different spark ...

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 ...

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 ...

There is no shortage of people around the world today who seem pretty certain that the days of the internal combustion engine (ICE) as the primary form of propulsion for transportation are effectively ...
