Dimpled pistons might sound strange, but some say they could be the future for diesel power. We've looked at the arguments ...

Modern piston engines are incorporating advancements such as fuel injection, turbocharging, and electronic controls (like Lycoming's iE2 system). Weight reduction is a key focus; engines like the ...

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 ...

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 ...

Gasoline and diesel engines feature many differences aside from fuel type. Compared to gasoline engines, a diesel is typically a lower-revving, torquier design, hence why it's often preferred over ...

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 ...

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 ...

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, ...

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 ...

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 ...
