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 ...

While most engines have the same number of spark plugs and cylinders, some four-cylinder blocks have two plugs for each ...

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 ...

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 ...

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 ...

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 ...
