What is a diesel engine?

In a gasoline or diesel engine, the fuel burns inside the cylinders themselves. Internal combustion wastes much less energy because the heat doesn't have to flow from where it's produced into the cylinder: everything happens in the same place. That's why internal combustion engines are more efficient than external combustion engines (they produce more energy from the same volume of fuel).

What does a diesel engine need to start?

The most common method for starting a diesel engine is through the use of glow plugs. Like an air intake heater, the glow plugs operate off of the power of the vehicle's battery. This pre-warming process brings the air in the combustion chamber up to a temperature conducive to cold starting.

Whereas a gas engine starts when the fuel is ignited by the spark plug, diesel engines rely on the heat created by compression in the chamber. Sometimes, such as during cold weather, the diesel fuel needs the aid of an outside source of heat to reach the appropriate temperature to start.

what is the six stroke diesel engine?

The six stroke Diesel engine is an internal combustion (IC) engine in which the piston completes six separate strokes while turning a crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction.

How is diesel engine work?

The diesel engine gains its energy by burning fuel injected or sprayed into the compressed, hot air charge within the cylinder. The air must be heated to a temperature greater than the temperature at which the injected fuel can ignite. Fuel sprayed into air that has a temperature higher than the “auto-ignition” temperature of the fuel spontaneously reacts with the oxygen in the air and burns. Air temperatures are typically in excess of 526 °C; however, at engine start-up, supplemental heating of the cylinders is sometimes employed, since the temperature of the air within the cylinders is determined by both the engine’s compression ratio and its current operating temperature. Diesel engines are sometimes called compression-ignition engines because initiation of combustion relies on air heated by compression rather than on an electric spark.
