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 ...

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 ...

Spark plugs are vital for gas-powered cars. However, they can be subject to a strange phenomenon known as blow out. Here's what that means and how to fix it.

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 ...

Spark plugs are essential for gas-powered engines. However, they're not all created equal. Here's what can happen if you use ...

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 ...

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 ...

The reciprocating internal combustion engine is a well proven and familiar technology with decades of use for stationary power generation. Unfortunately, familiarity occasionally results in assumed ...

Mazda’s new SkyActiv-X engine will go against every convention you thought you understood about gasoline engines. It’s supercharged, but for efficiency purposes, not to increase power. It has a ...

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 ...

A spark plug can eject either due to poor design or a lack of sufficient torquing. You can fix this by tightening a loose ...
