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 ...

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

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 ...

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 ...

[Dan] wanted to learn a bit about solid state ignition in engines; to get started he needed a test subject, so he decided he would upgrade his old 12 horsepower lawnmower. Originally the lawnmower ...

Man, time flies. It seems like just a couple years ago when GM introduced the first major renovation of its small-block, but of course, that was back in 1991 for the '92 Corvette. At the time, one of ...

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 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 ...

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 ...

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