Some of the world’s most complicated engines were created to achieve a specific objective. These engines were built to ...

No experienced engine builder would intentionally bolt a cylinder head to an engine block without installing a gasket between the block and cylinder head. The gasket seals the block-deck surface to ...

Pop the hood on a classic Mazda RX-7 or RX-8 and the engine bay looks […] ...

Navistar International Corporation today announced it has reached a development agreement with EcoMotors International in support of the company’s opoc (Opposed-Piston, Opposed-Cylinder) engine ...

V-shaped engines like the V6 and V8 power lots of cars, but you probably never think about what, exactly, that V angle is.

Over the roar from a 110-cc, two-cylinder engine, Pinnacle Engines founder James Cleeves (nicknamed Monty), pointed out a window in the block. "You can see the cylinder sleeve moving for the intake ...

1. EcoMotors is developing high-efficiency engines — specifically the unique opoc (Opposed Piston Opposed Cylinder) engine — for use in cars, light trucks, marine applications, agricultural vehicles, ...

The first recognizable internal combustion engine was developed by Nikolaus Otto in 1861. Since then, the gasoline-powered engine has evolved immensely. However, the principles that underlie how ...

Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

Ford once sketched a road where an engine's pistons never saw oil and engines ran hotter on purpose. In a late‑1980s patent application filed and granted in Europe, the company described an "uncooled ...

While Tesla, General Motors, Nissan, BMW and other automakers doggedly push to bring battery-powered vehicles into the mainstream, Achates (a-KATE-ezz) Power engineers are betting that an old ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...
