Study Notes

Engine Cooling System

The radiator is responsible for regulating the temperature of the engine in a car by dissipating heat from the coolant.
The water pump circulates the coolant through the engine and radiator to maintain a stable temperature.
The thermostat helps regulate the engine temperature by controlling the flow of coolant.

Exhaust System

The SCR (Selective Catalytic Reduction), DEF (Diesel Exhaust Fluid), and DPF (Diesel Particulate Filter) work together to reduce NOx emissions and particulate matter in diesel engines.
The catalytic converter is responsible for reducing toxic emissions from the engine.

Turbocharger

The turbocharger is responsible for increasing the power output of an engine by compressing air and forcing it into the engine's cylinders.
The turbocharger is powered by the exhaust gases, which drive the turbine.

Coolant System

Ethylene glycol and water are used as a coolant mixture to transfer heat from the engine to the radiator.
The coolant mixture prevents the engine from overheating and freezing.

Power Trains

The sprocket is a toothed wheel that transmits power from the engine to the vehicle's wheels.
The turbocharger is also used in the power trains to increase power output.

Lubrication System

Synthetic oil is used in the lubrication system due to its superior performance in extreme temperatures and its ability to protect the engine from wear.

Refrigeration Cycle

The compressor is responsible for compressing the refrigerant in a compressed gas refrigeration cycle.

Engine Oil

SAE (Society of Automotive Engineers) and API (American Petroleum Institute) viscosity ratings are used to classify engine oil based on its thickness and flowability.
