Diesel engine combustion is the process of combusting _______________ to create an expanding gas that makes the engine operate.
Turbochargers are centrifugal compressors driven by the exhaust gas turbines.
Superchargers are:
(1) Compressors
(2) Driven mechanically by engine crankshaft
(3) Used for increasing the air pressure above atmospheric pressure
Which of the above are true?
two-pulse turbocharging
constant-pressure turbocharging
three-pulse turbocharging
Inadequate scavenging leads to low amount of oxygen availability which results in incomplete combustion leading to higher specific fuel combustion.
What is used in engines to reduce the noise at the exhaust?
The process of clearing the cylinder after the expansion stroke is called scavenging process.
If the temperature of charge intake air increases, then the engine's efficiency will:
Combustion process plays an important role in controlling and reducing the NOx emission.
The power developed by the turbocharger is not sufficient to drive the air compressor, and overcome its mechanical friction.
In a four stroke engine, the combustion process takes place every:
