It's important to keep in mind that the combustion process occurs in a very brief period of time. Due to a variety of conditions that include mixture density, homogeneity, temperature, fuel ...

It's been a long time since the automotive world has bothered with the mixing of oil and gas of the two-stroke combustion cycle — but soon, it may come time to rid ourselves of four-stroke engines, if ...

NOTE: With this issue of HOT ROD, your Shop Series begins a slightly different and more comprehensive approach to the discussion of engine and vehicle basics. In the coming months, you'll find a frank ...

The utilization of thermodynamics-based modeling emerged as a valuable technique to simulate various complex phenomena and their interactions occurring in a thermodynamic system. This paper presents a ...

Internal combustion engines typically have low efficiency, with modern gasoline engines around 35% and diesel engines ...

An experimental hydrogen engine developed by researchers at the University of Magdeburg offers better performance than diesel ...

Almost all gasoline engines, whether they're efficient-yet-less-refined four-cylinders, high-horsepower V6s, or growly and torque-rich V8s, use much the same process to create power. The "Otto cycle" ...

Aerojet, a GenCorp Inc. company, announced today that America’s only staged combustion liquid rocket booster engine currently in development achieved an important milestone July 12 at NASA’s Stennis ...

I want you to picture this scenario in your head: It’s a Sunday morning, and you wake up excited to go on your usual Sunday morning ride. You head to your garage, all geared up for the ride. You put ...

The realm of pistons and internal combustion has been on an evolutionary arms race since the very first power stroke of the Big Bang that started the reciprocating piston revolution. Stronger, faster, ...

A better mousetrap? Even now, as electrification seems poised to end the internal combustion engine’s long run as the transportation motivator of choice, enterprising tinkerers continue to propose ...
