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.
