For car enthusiasts and performance seekers, optimizing engine response is a thrilling endeavor. Ignition systems play a ...

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 ...

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 ...

Spark plugs can only ignite the fuel at one end of the chamber. A laser ignites the fuel in the middle of the chamber instead, burning more of the fuel and improving combustion efficiency by 27 per ...

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 ...

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 ...

All combustion type engines require two variables to make power-air and fuel (gas, alcohol, methanol, etc). More air and fuel in the combustion chamber means more power potential. However, in reality ...

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...

Something about engine spark plugs that rarely seems to get mentioned is indexing. What is it, actually? Should you index the ...

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 ...

In the interest of making sure we all know they've got a mapped strategy for powertrain technology, GM is taking its message on the road. Recently, we got the chance to talk to a few of GM's experts ...
