Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has ...

Power Stroke Diesel engines provided thrust for Ford Super Duty rigs for decades, but there are some key differences between ...

When I went to school for engine repair in the 1980s, we studied the differences between two- and four-stroke engine cycles extensively. If you're not familiar with engine strokes, understanding the ...

The two-stroke gasoline engine was once a marvel of engineering, offering up huge doses of power in small and lightweight packages. Unfortunately, gas two-strokes also burn oil by design, making them ...

The 6.0 Power Stroke diesel's distinctive whistle came from its turbine wheel. Its design was updated after 2003, thus removing the whistle.

The problem with that design is that it means lubrication cannot be added below the cylinder, as that is now a pre-combustion intake chamber. And in order for the compression stroke to work as the ...

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 ...

One of the most significant contributions in the history of propulsion technology came from a 19th-century engineer named Rudolf Diesel. While his idea was patented in the 1890s, it wouldn't be until ...

Have you ever wondered why you need to add oil to your chainsaw’s fuel supply? Or why some dirt bikes have a higher pitched exhaust note than others? We’ve all been burdened with yard work or been ...
