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

Here in 2019, only the most fringe reactionaries are able to claim with a straight face that climate change is not a thing. But after years of the media doing its “two sides” thing, recalcitrant ...

ABSTRACT Turbulent Jet Ignition is an advanced pre-chamber initiated combustion system for an otherwise standard spark ignition engine found in current on-road vehicles. This type of ignition enables ...

WEST LAFAYETTE, Ind. – The same technology used in jets soon may be powering personal cars and other automobiles. Purdue University researchers are now working to develop pre-chamber technology for ...

In response to stricter global emissions standards, automakers are looking for new ways to wring every last bit of efficiency out of the internal-combustion engine. In this Engineering Explained video ...

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 ...

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 ...

Purdue University researchers are working on methods to use jet ignition technology to help power personal cars and other automobiles. (Stock photo) The same technology used in jets soon may be ...
