Free piston engines could achieve efficiencies of 50% which is almost double a regular gas combustion engine. However, new super efficient diesel engines could be even better, plus diesels would be ...

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, ...

An engine with no crankshaft, where the pistons float on air? It’s not a dream; it’s a free piston engine and it might be the next major advance in car tech. When we think of automotive technology of ...

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 ...

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 ...

Piston heads form a significant part of all gasoline, diesel, and alternate fuel passenger and commercial vehicles. They bear the brunt of high pressure and temperature and are, hence, made of special ...

Horizontally-opposed engines are often referred to as "boxer" engines because the motion of the pistons sort of resembles a boxer, punching. Really, though, if any engine should be named for a boxer, ...

Hannover, Germany, September 23, 2014- Federal-Mogul Powertrain, a division of Federal-Mogul Holdings Corporation (FDML) has significantly reduced the friction of heavy-duty diesel piston rings by a ...

Achates Power’s heavy-duty opposed-piston diesel engine is the only diesel engine operating on the road capable of meeting CARB’s 2027 regulation. Achates Power’s cleaner, heavy-duty diesel engine it ...

Solid lubricants such as graphite and carbon fibre reinforced polymer form the EcoTough coating for diesel engine pistons to reduce friction, and improve efficiency, refinement and durability of ...
