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 ...

The Environmental Protection Agency (EPA) proposes to establish standards for emissions of particulate matter (PM) and nitrogen oxides (NOx) from marine compression-ignition engines less than 30 ...

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 ...

Let's discuss something that is well known by diesel mechanics and hard-core enthusiasts but may not be fully understood by new diesel owners or people who may have heard the term "compression ...

Because diesel vehicles do not use spark plugs, they must rely on higher compression ratios to ignite the diesel fuel without ...

Billed as the Next Big Thing for the gasoline engine, Homogeneous Charge Compression Ignition (HCCI) allows for diesel-like operation wherein compression, not spark, combusts lean air/gasoline ...

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 ...
