Little ENGINES ENGINE OPERATION FOR A FOUR STROKE ENGINE

Slide 2

SMALL ENGINES A motor is a gadget which changes over vitality into mechanical movement to do work. Little motors are depicted as inner burning motors appraised up to 25 pull . A little motor has either a start or a pressure start in light of how the fuel is touched off. Little motors are named either four-stroke cycle motors or two-stroke cycle motors.

Slide 3

PARTS OF THE ENGINE CYLINDER BLOCK Engine segment which comprises of the barrel bore, cooling balances, and valve prepare segments. Made of cast aluminum combination that are lightweight and disperse warm quickly. Chamber HEAD Engine segment made out of cast aluminum amalgam attached to the end of the barrel piece most distant from the crankshaft. COOLING FINS A necessary thin cast strip intended to give productive air course and dispersal of warmth far from the motor chamber obstruct into the air stream. HEAD GASKET A filler material put between the barrel piece and chamber go to seal the burning chamber. Made of delicate metals and graphite layered together. Start PLUG Component that detaches the power and creates the start for the motor

Slide 4

PARTS OF THE ENGINE PISTON A tube shaped motor segment that slides forward and backward in the barrel bore by powers delivered amid the burning procedure. Interfacing ROD Engine segment that exchanges movement from the cylinder to the crankshaft and capacities as a lever arm. CRANKSHAFT A motor segment that proselytes straight (responding) movement of the cylinder into turning movement. FLYWHEEL A cast press circle that is mounted toward one side of the crankshaft to give idleness to the motor. Stabilizers A jutting mass cast into the crankshaft which halfway adjusts the strengths of a responding cylinder.

Slide 5

PARTS OF THE ENGINE PISTON: A barrel shaped motor segment that slides forward and backward in the chamber bore by powers created amid the ignition procedure.

Slide 6

PARTS OF THE ENGINE PISTON: DIFFERENT PISTON TYPES: FLAT IRREGULAR DISHED DOMED

Slide 7

PARTS OF THE ENGINE PISTON RINGS: An expandable split ring used to give a seal between the cylinder and the barrel divider Three sorts: COMPRESSION RING WIPER RING OIL RING 1 2 3

Slide 8

PARTS OF THE ENGINE VALVE TRAIN VALVE HEAD MARGIN VALVE FACE VALVE SEAT VALVE NECK VALVE GUIDE VALVE SPRING VALVE ROTATOR VALVE SPRING RETAINER

Slide 9

FOUR STROKE CYCLE ENGINE INTAKE STROKE COMPRESSION STROKE POWER STROKE EXHAUST STROKE

Slide 10

INTAKE STROKE Occurs from TDC to BDC Intake valve opens Air-Fuel that was already blended in the carburetor is currently sucked into the ignition chamber because of the low weight made inside.

Slide 11

COMPRESSION STROKE Compresses the Air-Fuel blend By packing the Air-Fuel blend: Allows for more vitality to be discharged. Expands fuel vaporization Allows for more entire smoldering

Slide 12

POWER STROKE Spark happens lighting packed air-fuel blend Spark happens 20 degrees before TDC so the fire front can spread all through burning chamber Gasses touch off pushing cylinder far from the barrel head Linear movement from the cylinder is moved into a turning movement on the crankshaft

Slide 13

EXHAUST STROKE Exhaust valve opens Inertia from the flywheel and different parts push the cylinder move down toward TDC, pushing the spent gasses out of the ignition chamber.
