Ignition coils last far longer than spark plugs and only need replacement when symptoms appear. Here’s how to tell if coils ...

As long as the internal combustion engine has existed, engineers have been trying to find better ways of igniting the highly combustable mixture of air and gasoline that powers cars. Everything from ...

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 ...

Most pickup trucks sold today have internal combustion engines. Passenger vehicles are powered by two main types of engines: compression, aka diesel, and spark ignition, aka gasoline. Besides the type ...

Engine cylinders can misfire for many reasons. There are four causes in particular that you should be aware of; here's what ...

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 ...

IRVINE, Calif.—Despite rumors to the contrary, the internal combustion engine is far from dead. Recently we’ve seen several technological advances that will significantly boost the efficiency of ...

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 lack of clearly identified constraints for ignition and flame propagation has hindered understanding the processes which limit lean operation in spark ignition engines. This experimental study ...

A few years ago sparkless ignition or homogeneous charge compression ignition (HCCI) in gasoline engines was all the rage, with a number of major automakers including General Motors, Daimler and ...

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 ...

You own a diesel-powered vehicle and are thinking of giving it a tuneup. But does your diesel even have spark plugs to change? The short answer is no, diesel engines do not have spark plugs. Instead, ...
