Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating the ...

When you're at an airport and see propeller aircraft, you likely think it is powered by a piston engine. This is usually true among smaller planes, like the Cessa 172 Skyhawk and the Piper Archer, or ...

Researchers are working to study the fundamental physics of diesel engines. Understanding the fundamentals could lead to better engine performance, fuel economy and power. The compression-ignition, ...

Just about every piston engine is defined by two basic measurements: bore and stroke. Bore is the diameter of the cylinder. Stroke is the distance the piston travels from bottom dead center to top ...

Golf balls have dimples, so they fly farther than balls that don't. Apply the same principle to diesel engines, and you have a gross oversimplification of why dimpled pistons were invented. It's a ...

During this fast chat, we will be discussing the fundamentals of Piston Aviation Engine Oil. We'll dive into everything you need to know, covering topics such as viscosity, lubricant functions, ...

The piston skirt and pin account for about 17 percent of the frictional loss in a combustion engine as they are the most difficult to keep lubricated and have the largest contact surfaces. OE ...

The opposed-piston engine has been around for over 100 years and is more efficient in almost every way. The engine has no traditional valves, cams, or camshafts, and no head, so it’s simpler and ...
