Engines and Motors
Types Internal Combustion Engines External Combustion Engines
Internal Combustion-Basic PartsCrankcase Crankshaft Piston Piston Rings Connecting Rod 4-Stroke Engine Valvetrain Camshaft Valves
Crankcase Main Structural component of the engine.
Piston Cylindrical part fitted in a cylinderTransmits power created by the combusting fuel & air
Piston Rings Seals the Piston to the Cylinder Wall
Connecting Rod Links Crankshaft to Piston
Crankshaft Converts the Linear motion of the piston to a Rotary motion.
4-Stroke Engine-ValvetrainCamshaft Operates Valves Valves Open and Close Ports
Internal Combustion Engines4-Stroke Gas 2-Stroke Gas
4-Stroke Gas Engines 4 Stroke / Cycle Intake Compression Power Exhaust
Intake Stroke Piston moves down drawing in fuel and air.
4-Stroke Gas Engines - Intake
4-Stroke Gas Engines - CompressionPiston moves up, squeezing the fuel and air
4-Stroke Gas Engines - Compression
4-Stroke Gas Engines - PowerNear Top Dead Center spark ignites the fuel and air combusting the vapor forcing the piston down.
4-Stroke Gas Engines - Power
4-Stroke Gas Engines - ExhaustPiston moves up forcing out the spent gasses
4-Stroke Gas Engines - Exhaust
4-Stroke Gas Engines 4-Stroke In Action Pros Cons Easy to RefuelLight Weight Inexpensive Cons Only 30% Efficient
2-Stroke Gas Engines Completes the 4-cycles in 2-strokes No ValvetrainUses Transfer Ports
2-Stroke Gas Engines 2-Stroke in action Advantages: Disadvantages:Less Moving Parts Light Weight Twice as Powerful Operating Position Disadvantages: Frequent Rebuilds Pollution Burns Oil

5 Principles of Engine Operation, Two- and Four-Stroke Engines.
Vigyan Ashram, Pabal. In this presentation you will learn : – What is IC engine? – How it works? – Where it is used?
Small Engine Theory What is the purpose of a Small Engine?
During the intake or admission stroke, the piston moves downward as a charge of combustible fuel and air is admitted into the cylinder through the open.
Two Stroke The biggest diesel engine in operation, work on two stroke principle. It is called two stroke because it takes two strokes of piston to complete.
