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 ...

With every passing day the Mule provides opportunities beyond our original expectations. Since the 467ci engine belongs to HPP editor Tom DeMauro, it is at our beck and call. This affords HPP the ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

Nissan brought the first, and only, variable-compression engine to market. But its future doesn't look bright. Complexity in cars is a funny thing. It’s tempting to say that it’s all bad, that more is ...

Despite the turbulence Nissan has faced over the past few years, some of its technology is undeniably impressive. Perhaps the crowning jewel of this engineering power is its variable compression ...

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 ...

For hundreds of years of human history, the invention that has defined our ability to travel, explore, and expand our boundaries has been the combustion engine. This hallmark of mechanical development ...

Any oddball engine is clickbait crack for mechanical nerds, and the most compelling ones purport to introduce an entirely new combustion concept. "Not a four-stroke, not a two-stroke, a revolutionary ...
