Study Notes
Engine Classification
- Engines need fuel, ignition, and compression to run.
- Four-stroke gasoline engine: Uses a four-stroke cycle for combustion.
- Two-stroke gasoline engine: Uses a two-stroke cycle for combustion.
- Diesel engine: Uses compression ignition.
Engine Parts
- Cylinder block: Main part of the engine where combustion takes place.
- Cylinder: Holds the piston and is a part of the cylinder block.
- Cam shaft: Operates the intake and exhaust valves.
- Cam lobe: Changes rotary motion into reciprocating motion.
- Double Overhead Cam: Refers to the camshaft being located above the cylinder head.
- Valves: Inlet and exhaust valves control the flow of air and exhaust gases.
- Valve springs: Close the valves after they've been lifted by the camshaft.
- Valve lifters: Ride on the cam lobe and help open the valves.
- Spark plug: Provides ignition for gasoline engines.
- Piston: A movable part fitted into a cylinder that transforms the power of the explosion into rotational movement.
- Cylinder head: Covers the cylinder and contains cooling fins or water jackets, as well as valves.
- Connecting rod: Attaches the piston to the crankshaft.
- Crankshaft: Converts the up-and-down motion of the piston into circular motion.
- Piston rings: Help seal the combustion chamber and prevent oil from entering it.
- Blow-by: Can cause oil burning and blue/gray smoke.
- Flywheel: Attached to the crankshaft, reduces vibration, and transfers power to the drivetrain.
- Manifold: Distributes air-fuel mixture or collects exhaust gases.
- Gaskets: Seal the cylinder head and cylinder block.
- Engine Bearings: Reduce friction between moving parts.
- Firing order: The sequence in which cylinders ignite or inject fuel.
Cylinder Arrangement
- Inline engine: Cylinders are arranged in a line, in a single bank.
- V-engine: Cylinders are arranged in two banks, angled to each other.
- Flat engine: Cylinders are arranged in two banks on opposite sides of the engine.
