an engine that burns a special kind of oil

A vehicle with an engine that uses diesel fuel and compression ignition.

An internal combustion engine in which fuel oil is burnt by heat produced from air compression. The most commonly bought Industrial Diesel Engines are either Rebuilt Diesel Engine or Used Diesel Engine.   

According to 30 CFR 7.82 [Title 30- Mineral Resources -Chapter i-Mine Safety and Health Administration, Department of Labor -Subchapter b- Testing, Evaluation, and Approval of Mining Products-Part 7-T [..]

An internal combustion engine that uses compression to raise air temperature to the igniting point, whereas fuel is ignited by a spark in a gasoline engine.

An internal combustion engine in which the air fuel combustion mixture ignites entirely by the heat of compression.

Generally delivers better fuel economy and more pulling power than a comparable gas engine, but requires the use of diesel fuel, which is harder to find than gasoline and often costs more.

Oil engine in which ignition of fuel is caused by compression. Cycle comprises air compression, fuel injection, ignition, and scavenging. Cycle may be completed in two or four strokes.

A type of internal combustion engine that uses low-volatility petroleum fuel and fuel injectors and initiates combustion

An internal combustion engine that uses diesel oil for fuel. The true diesel does not use a carburetor or an ignition system (i.e., spark plugs) but injects diesel oil into the cylinders when the pist [..]
