We all know how a conventional internal combustion engine works, with a piston and a crankshaft. But that’s by no means the only way to make an engine, and one of the slightly more unusual al… ...

When it comes to engines, everyone is always looking for more. More horsepower, more torque, more efficiency. One company has ...

In this detailed 3D animation, we take you through the intricate process of assembling an automobile internal combustion engine, showcasing each step of the engine-building process from start to ...

Opposed pistons share a combustion chamber in this venerable engine design, and Achates's refined version claims fuel-economy improvements.

The opposed-piston engine has been around for over 100 years and is more efficient in almost every way. ... On one such weekend he brought a book on opposed-piston internal combustion engine theory.

The free-piston engine has some similarities to the OPOC but generally only uses two pistons per module. The pistons are attached to each end of a solid connecting rod and oscillate back and forth ...

Beyond the combustion stroke, which pushes the piston down from the top of the cylinder, there are three other strokes: intake, compression, and exhaust. Engines need air (namely oxygen) to burn fuel.

Combustion ignition is a key characteristic of a diesel engine, and the easiest way to explain it is with a fire piston. These ancient fire-starting devices consisted of a piston with a recessed ...

The power generated by a combustion engine is derived from a combination of heat and pressure, generated through a series of pistons. An engine block contains several cylinders, topped off with an ...

The Namikoshi concept engine weighs in at roughly 90 kg (198 lb), has a cubic capacity of 1,500 cc and measures approximately 800 mm (31.5 in) wide by 500 mm (19.7 in) deep and 250 mm (9.8 in) tall.

Diesel engines have pistons that look different from the ones you'd see with a gas engine. ... a diesel pulls in air by creating a vacuum in the combustion chamber as the piston travels downward.

Weighing just 22 lb (10 kg), the simple engine uses a single moving piston to develop power. Beyond vehicles, Aquarius is developing the engine for use as an off-grid micro-generator. SUBSCRIBE ...
