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

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 ...

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 ...

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 ...

Building a diesel engine that does not use traditional pistons may seem odd, but in today's modern age of high efficiency, low emissions, and weight reduction, an engine with a nonconventional rotor ...

Diesel engines can technically run backwards, though there's very little (if any) practical applications for this, especially ...

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 ...

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, ...
