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 ...

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 ...

When we here in the modern age think of an “engine,” we are usually thinking of a four-stroke, four-cylinder, gasoline-fed, internal-combustion engine with the valves on the top. But why must that be ...

Bill Wong saw some interesting things at the Military Vehicles Exhibition and Conference (MVEC) including a quad opposed piston engine and a modular, off-road vehicle that can hit 120 mph using active ...

Achates Power’s cleaner, heavy-duty diesel engine it developed in a project funded by the California Air Resources Board and several partners has entered fleet service with Walmart in a Peterbilt 579 ...

Utah's Transcend Energy Group claims it has a relatively simple and cheap way to dramatically increase the torque output of combustion engines, simply by replacing the standard connecting rods with ...

Designed in the U.S and tested in a Walmart delivery vehicle all summer long, this revolutionary opposed piston 3-cylinder seems set to prolong the life of ICEs. However, you won’t be seeing it inside ...

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, ...

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 ...

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 ...
