The internal combustion engine, for all its mechanical sophistication, still runs on a 19th-century mechanical idea: pistons ...

In a single-cylinder engine, the ability to homogenize and maintain the fuel-air blend prior to and during the burn is a classic combustion-engine problem. Add additional cylinders, and introduce ...

Human creativity, it seems, knows no bounds when it comes to inventing new ways to build a petroleum-based fire inside an enclosed metal space and then convert the resulting energy pulse into forward ...

Through the history of internal combustion engines, there has been plenty of evolution, but few revolutions. Talk of radically different designs always leads to a single name – Wankel. The Wankel ...

It's amazing that an object as simple as a piston can withstand the rigors of combustion for hundreds of thousands of miles without failing. There's a lot more to a piston than meets the eye, matey.

Antony Ingram April 30, 2014 Comment Now! Despite the recent advent of usable, talented electric vehicles, combustion engines are likely to persist for quite some time, often as a component in plug-in ...

According to fleet executives as well as fleet maintenance managers, the death of the internal combustion engine may prove to be greatly exaggerated in spite of the excitement about electric ...

Half a dozen countries, including the U.K. and possibly also Germany, have now laid out plans to ban gas- and diesel-powered vehicles, while tough U.S. and Chinese emissions and mileage standards are ...
