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 ...

Light-duty compression-ignition (CI) engines operating on diesel fuels have the highest thermodynamic cycle efficiency of all light-duty engine types. The CI diesel thermodynamic cycle efficiency ...

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 ...

Heat initiates the internal combustion process. Diesel engines utilize the temperature buildup from extremely high compression (pressure) to ignite the air/fuel mixture, with a little help from glow ...

A German startup is developing a potential replacement for spark plugs: microwave pulse ignition. The tech is under development by MWI Micro Wave Ignition AG of Empfingen, Germany, which claims that ...

The automotive ignition system is an incredibly amazing machine that has evolved for more than 100 years already and continues to evolve as the demand drives the need to develop more efficient engines ...

Whether you service your own ignition or need more troubleshooting savvy for road rallies and cruising, this month's lesson focuses on spark and ignition system basics. Understanding ignition ...

The purpose of the ignition system is to ignite, or fire, the spark plugs in order to generate power to run the engine. Most vehicles built prior to 1974 use a non-electronic distributor ignition ...

No Ford engine project is complete without a properly functioning ignition system. This system has the important job of delivering the spark to the required cylinder at precisely the right time. Any ...

An ignition coil is a vital component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into the high voltage needed to produce sparks at the spark ...
