How does a 4 stroke diesel engine work?

How does a 4 stroke diesel engine work?

Intake stroke

  1. Piston moves down the cylinder bore from top dead center (TDC) to bottom dead center (BDC)
  2. Intake valve is open, the exhaust valve is closed.
  3. Downward piston motion creates a vacuum (negative air pressure) that draws that air/fuel mixture into the engine via the open intake valve.

How does diesel engine start?

As with petrol engines, diesel engines are started by being turned with an electric motor , which begins the compression-ignition cycle. When cold, however, diesel engines are difficult to start, simply because . compressing the air does not lead to a temperature that is high enough to ignite the fuel.

How a diesel generator works?

When the Diesel Generator is started, the engine goes through its four process of combustion, i.e Suction, Compression, Power and Exhaust. And as a result the chemical energy of fuel converts into mechanical energy, which we get as an output at the shaft of the engine.

What is a silent diesel generator?

A silent diesel generator is a combination of a diesel engine and an electric generator that is often used as a secondary source of electrical power in industrial and residential units. It is available in a variety of physical and electrical configurations.

What are the working principles of diesel engines?

This animation describes the working principles of diesel engines in the context of an inline-four engine that operates in a four-stroke mode. This kind of engine has four cylinders mounted in a straight line. Unlike the typical Otto-cycle engine, a diesel engine takes in only air through the intake valves during the 1st stroke.

How does a diesel engine run on alternating current?

This causes a great deal of electrical current to flow back and forth through the wires – what we call ‘alternating current’ or ‘AC’ mains power. This is typically the diesel fuel supply for the engine. The most obvious part is a tank holding enough fuel for at least 6-8 hours of operation.
