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 ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

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 ...

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 ...

There are engine assemblers, and then there are engine builders. It's one thing to merely bolt a bunch of parts together. It’s quite another thing to carefully assemble machined components to precise ...

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 ...

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, ...

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 ...
