Every new internal combustion car and truck sold in America today is equipped with a four-stroke engine, as are the vast ...

Detroit Diesel's 2-stroke diesel engines were eventually replaced with 4-stroke models, but parent company MTU still sells refurbished parts.

The Alpha-Otto REV Force is a supercharged two-stroke engine that supposedly runs cleaner, makes tons of power, and will run on pretty much anything from gasoline and diesel to kerosene to hydrogen.

Two-stroke diesel engines are commonplace in large container ships. Their thermal efficiency is around 50 per cent while four-stroke diesels struggle to reach 35 per cent.

The early history of Cummins is linked to the Indy 500, where the company raced both four-stroke and two-stroke engines in the 1930s.

In comparison to the traditional aircraft engines the new turbo diesel not only delivers considerably higher performance and torque but also 20 percent less fuel consumption.

But as far as a numbers-smashing fantastical build, this two-stroke 18.6-liter diesel hot rod is possibly the craziest. Of course, it looks completely unhinged.
