Study Notes

Engine Adaptation Component Parts

  • Engine assembly, Transaxle/Transmission, Flywheel, Clutch Assy, Starter Motor, Alternator, AC Compressor, Ac Liquid Pipe, Coolant Hoses, Hot End Assy, Air Intake assembly, Engine Mounts, Fuel Lines, Wiring Harness, and LKT Parts (Engine Belt, Tensioner, Feed brkt) are the engine adaptation component parts.

Engine

  • An engine is a machine designed to convert one or more forms of energy into mechanical energy.
  • Mechanical energy is essential for transportation and industrial processes like cutting, grinding, crushing, and mixing.
  • The engine consists of a fixed cylinder and a moving piston, which converts the expanding combustion gases into mechanical energy.
  • The main function of an engine is to transform fuel into energy.
  • There are two main types of engines: Internal Combustion Engine and External Combustion Engine.

Transmission

  • A transmission acts as a medium that transmits power generated by the engine to the wheels via a mechanical system of gears and gear trains.
  • The purpose of transmission is to vary the torque at the wheels.
  • Examples of transmission types include Automated Manual Transmission (AMT), Continuously Variable Transmission (CVT), Dual Clutch Transmission (DCT), Intelligent Manual Transmission (iMT), and Torque Convertor Auto.

Flywheel

  • A flywheel is a weighty, round disc connected to the engine's crankshaft.
  • The main job of a flywheel is to store kinetic energy that can be used to power the vehicle and prevent it from stalling.
  • There are two types of flywheel: Solid Flywheel and Dual Mass Flywheel (DMF).

Clutch Assy

  • A clutch is a mechanical device that allows the output shaft to be disconnected from the rotating input shaft.
  • The clutch acts as a mechanical linkage between the engine and transmission.
  • Types of clutches include Wet clutch, Dry clutch, Centrifugal clutch, Cone clutch, and Dog clutch.
  • Subparts of the clutch include Clutch plate, cover assy, CRC-Clutch Release Cylinder, CMC-Clutch Master Cylinder, and Clutch Fluid Hose.

Starter Motor

  • A motor starter provides defense by controlling the electrical output of the device or equipment at its initial point of operation.
  • The two main types of starters are Manual Starters and AC Magnetic Motor Starters.

Alternator

  • An alternator converts chemical energy into electrical energy to charge and replenish the battery in the engine and other electrical components.
  • The alternator function is to convert some of the mechanical energy from the motor into electrical energy.

AC Compressor

  • The compressor is the power unit of the air-conditioning system that puts the refrigerant under high pressure.
  • The compressor is responsible for compressing refrigerant vapor.
  • The compressor is the heart of the HVAC system, transferring heat from the refrigerant to the condenser.

AC Liquid Pipe

  • The AC hose pipe carries the refrigerant in both its gaseous and liquid states, depending on the specific section of the AC system.
  • The AC hose pipe helps regulate the temperature inside the vehicle.

Coolant Hoses

  • Coolant hoses carry fluid from the radiator to the engine and back again.
  • Each hose is made of different materials depending on its purpose.
  • A properly functioning hose is essential for keeping a vehicle running smoothly.

Hot End Assy

  • The exhaust system collects the exhaust gases from the cylinders, removes harmful substances, reduces the level of noise, and discharges the purified exhaust gases.
  • The exhaust system has four main functions: to control noise, to direct exhaust fumes away from passengers, to improve the performance of the engine, and to improve fuel consumption.
  • Subparts of the hot end assembly include o2, Nox Sensors, and Delta pressure Pipe.

Air Intake

  • The purpose of an air intake system is to provide oxygen to the engine, which is essential for burning gasoline.
  • More oxygen means more power from the engine, so improved airflow is an excellent way to increase the performance of the vehicle.
  • The modern automobile air intake system has three main parts: an air filter, mass flow sensor, and throttle body.

Engine Mounts

  • Motor mounts, also called engine mounts, are structural components that connect the engine to the vehicle frame.
  • They help stabilize the engine and vibrations, absorb shocks, and absorb engine movement during acceleration and deceleration.

Engine Fuel Lines

  • Fuel lines are multilayer plastic lines that supply and transport both fuel and/or fuel vapor from the filler head to the fuel tank and into the engine.
  • There are three types of fuel lines: heavyweight lines for high pressures, medium weight lines for light or medium fuel pressures, and lightweight lines where there is little or no pressure.

Wiring Harness

  • An engine wiring harness is an organized set of wires, cables, connectors, and terminals that controls a vehicle's electrical system.
  • The wire harness reduces labor time and potential for human error, enabling technicians to fit complex wiring assemblies into small or hard-to-reach spaces.

LKT Parts (Engine Belt, Tensioner, Feed brkt)

  • A serpentine belt is one long rubber belt that provides power to many vital components in the car, such as the alternator, power steering pump, air conditioning, and sometimes the water pump.
  • The tensioner is responsible for ensuring the correct amount of tension is applied to the belt so as to maintain synchronous drive.
  • The feed bracket is used to secure the alternator in place using a bracket that attaches to specific engine points.
