Scavenging Air in Diesel Engine means (a) Air Used for Combustion sent Under Pressure, (b) Forced Air for Cooling Cylinder, (c) Burnt Air Containing Products of Combustion, (d) Air Used for Forcing Burnt Gases Out of Engine’s Cylinder During the Exhaust Period.

Answer: Air is used for forcing burnt gases out of the engine’s cylinder during the exhaust period.

• The compression-ignition engine is another name for the diesel engine.

• The diesel engine is named after Rudolf Diesel.

• The fuel is inoculated into the combustion chamber in diesel engines, where it is subsequently ignited by the high temperature of the air in the chamber. Because of the adiabatic compression, the air in the cylinder is extremely hot.

• When Diesel fuel is injected into the combustion chamber, it spontaneously ignites. The Diesel cycle, which consists of a constant pressure process, a constant volume process, and two isentropic processes, is used in these engines.
