Some agree that batteries are the clear winner in the race against hydrogen technologies, while others think the opposite. There's no such debate among internal combustion engine proponents. Almost ...

Engineers are struggling to make the combustion engine run purely on hydrogen, but scientists believe there is an easier way. Engineers at the University of New South Wales (UNSW) in Sydney have ...

Diesel engine combustion is governed by high-pressure injection of liquid fuel into hot, compressed air, leading to rapid auto-ignition and flame development. Key fuel properties—cetane number, ...

Internal combustion engines are incredibly complicated machines that many of us interact with on a daily basis, but don't completely understand. You get in your car, turn the key or push the start ...

Internal combustion engines are literally the engines of the modern world. Without the invention of these genius mechanical creations, our world would be markedly different and the pace of life would ...

Any certified gearhead knows that diesel engines do not use spark plugs. But why not? If power in an engine is created by combustion or explosion of flammable liquids, won't a spark plug in a diesel ...

Carbon emission-free engines that burn hydrogen increasingly look like a viable technology for vehicles that range from race cars to cement mixers. The motorsport department at Austrian automotive ...

The original concept of combustion engines as we understand them dates as far back as the late 1800s. And while they are more or less a solved science today, they definitely didn't start that way.
