The diesel engine, however, actually burns oil in its liquid state.
In the diesel engine, which is a constant pressure engine, the ratio is usually 1⁄12th.
The cough of a diesel engine exhaust and the clanking of gear told him that a ship was nearing.
The diesel engine is in a class by itself, its cycle and method of control being somewhat different from the others.
We found in the diesel engine that when air is highly compressed it becomes very hot.
In the diesel engine there are no spark-plugs and no magneto: the engine fires itself without241 electrical help.
Inherently the diesel engine must stand higher pressures and therefore is heavier per horsepower.
An internal-combustion engine in which the fuel oil is ignited by the heat of air that has been highly compressed in the cylinder, rather than by a spark. Due to the need for the engine to withstand very high pressures, diesel engines are relatively heavy; however, they are relatively fuel-efficient, especially when running at low power.
