Components of an engine in Automotive_.pptx

Presentation about automotive.

1. UNDERSTANDING COMPONENTS OF ENGINE PARTS

2. Objectives At the end of the lesson, The learners will be able to; Define the Components of an engine Identify The various parts of an engine Explain the importance Each part of engine and its Functions

3. Motivation guess the picture 🤔

4. Components an engine PISTON A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion.

5. Intake or exhaust valves The up and down motion of the valve opens and closes the engine’s combustion chamber. Intake valves open and close the fresh air intake (or air/fuel mixture intake, depending on the engine). Exhaust valves open and close the outlet for exhaust gases.

6. The engine block houses all of the major components that make up the bottom end of a motor. The block, which is also known as the cylinder block, is where the crankshaft spins, and the pistons move up and down in the cylinder bores, fired by the fuel combusting.

7. Camshafts are integral components of internal combustion engines, responsible for controlling the opening and closing of the engine’s intake and exhaust valves. As the camshaft rotates, its lobes push against the valves, allowing the intake of air and fuel and the expulsion of exhaust gases.

8. A crankshaft is a mechanical component in a piston engine that converts the reciprocating motion of the pistons into rotational motion. It’s a rotating shaft with crankpins that are driven by the pistons through connecting rods.

9. A spark plug is a small electrical device that ignites the fuel and air mixture in an internal combustion engine, allowing the engine to run:

10. A lubrication system is a method for reducing friction between two surfaces that rub together by introducing a substance called a lubricant. Lubricants are usually oils or greases.
Lubrication systems are important for the efficiency and longevity of rotating equipment. They help to: Reduce friction and wear, Absorb and reduce shocks, and Protect from corrosion.

11. A cylinder head is a crucial part of an internal combustion engine that covers the top of the cylinders and forms the roof of the combustion chamber. It’s responsible for many functions, including:
Controlling airflow
The cylinder head has passages, also known as ports or tracks, that allow air to travel to the inlet valves.
Fuel deployment
The cylinder head holds the fuel injectors.
Thermal insulation
The cylinder head is uncooled to reduce heat rejection and improve engine efficiency.
Absorbing heat
Coolant from the radiator flows through passages in the cylinder head to absorb heat from the engine.
Resisting stress
The cylinder head is the most highly loaded element in the engine and must resist high levels of thermal and mechanical stress.

12. Flywheel, heavy wheel attached to a rotating shaft so as to smooth out delivery of power from a motor to a machine. The inertia of the flywheel opposes and moderates fluctuations in the speed of the engine and stores the excess energy for intermittent use.

13. A cooling system is a system of pipes, vessels, and pressure components that removes heat from a space or equipment to prevent overheating. Cooling systems are used to keep temperatures under control, ensure comfort in enclosed spaces, and prevent damage to machinery.

14. Assessment GIVE AT LEAST ONE OF THE COMPONENTS OF an ENGINE and Explain its function

15. Assignment Advance study of internal combustion engine
