How does a 4 stroke diesel engine work?
Intake stroke
- Piston moves down the cylinder bore from top dead center (TDC) to bottom dead center (BDC)
- Intake valve is open, the exhaust valve is closed.
- 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.
