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 ...

Compression in a diesel engine is essential for effective and efficient performance. And when compression is lacking, damage can result. That is why it’s imperative to know whether your engine’s ...

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as ...

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...

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, ...

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 ...

October 3, 2005 It has been a sudden realisation - the world is running out of oil and the laws of supply and demand are set to make petrol prohibitively expensive in the very near future. Sonex ...
