Navistar International announced that it is involved in an agreement with Eco Motors International supporting the development of the latter company’s OPOC—opposed piston, opposed cylinder—engine. The ...

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 ...

Remarkable innovations have been made to automotive technology since Karl Benz introduced the world to the "Motorwagen" in 1866 and Henry Ford gave rise to the American auto industry with the Model T ...

Developing new engines that perform better, weigh less, use less fuel, and meet stringent emissions standards is the primary goal of most engineers and automotive corporations. Companies continually ...

DETROIT — While Tesla, General Motors, Nissan, BMW and other automakers doggedly push to bring battery-powered vehicles into the mainstream, Achates Power engineers are betting that an old technology ...

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, ...

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, ...

A pair of heavy-duty opposed-piston engines will be produced for an emissions-reduction project in California, officials with the program announced Nov. 8 at a press event in San Diego. The two 10.6L, ...

Motor vehicle engine design has remained fairly standard throughout the history of the technology, although things have evolved quite a bit from the T-4 engine that powered Henry Ford's pioneering ...

Terry Knight, from Engineering TV, and I had an interesting time at the Military Vehicles Exhibition and Conference (MVEC) this week. There were plenty of connectors, electronics and simulators at the ...

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 ...
