Common Rail injection system The Common Rail injection system represents a fuel injection system for diesel engines with a high- pressure battery. The Common Rail injection system represents a fuel injection system for diesel engines with a high-pressure battery.

steam engine principle steam engines need fuel to make fire fire boils water which turns into steam steam goes through a valve and then pushes on a piston piston goes back and forth and turns wheels connecting rod hooks piston to a wheel

diesel engine diesel engine air is compressed more than in a gasoline engine injector squirts fuel within cylinder when fuel hits hot air it ignites the fuel diesel engine doesn't need a carburetor or spark plug

gasoline engine1 ( spark plug) ignites air and fuel to make much heat 175 explosions per minute per cylinder when your car is idling

gasoline engine2 ( carburetor) -controls gas and air amount -lets them into cylinders

gasoline engine 3 (radiator1) engine water takes heat away from engine into radiator radiator cools this water

gasoline engine 4 (radiator2) to blow through the radiator to cool the engine

INTERNAL COMBUSTION ENGINE1

INTERNAL COMBUSTION ENGINE 2 1.combustion inside a cylinder 2.to mix fuel and air together 3.mixing happens within carburetor 4.mixture of fuel and air goes through a valve into cylinder 5.here fuel and air get compressed by piston

INTERNAL COMBUSTION ENGINE 3 6.spark plug makes a spark and ignites air and fuel mixture 7.explosion pushes the piston down 8.piston pushes the connecting rod which turns crankshaft 9.crankshaft turns the flywheel 10. spinning fly wheel is used to do some kind of work

STATIONARY ENGINE PARTS (engine block and cylinder) engine block contains cylinder cylinder holds gas and air

ROTARY ENGINE PARTS1 (camshaft) to move intake valve exhaust valve

ROTARY ENGINE PARTS 2 ( crankshaft) -hooks all eight connecting rods together -makes circular motion

RECIPROCATING ENGINE PARTS1 ( valves) Exhaust Valve lets the burned fuel and air out of the cylinder up to 1200 degrees F Intake Valve lets air and unburned fuel into the cylinder

RECIPROCATING ENGINE PARTS 2 (connecting rod) connects piston to crankshaft

RECIPROCATING ENGINE PARTS 3 ( valve lifters) …intakes the fuel …is big …gets burned valve lifter2 …lets fuel out …is not big …gets burned the most

Conclusion and tasks Now you know about…. --rail injection system. --steam engine principle. --diesel engine. --gasoline engine. Let work with… --internal combustion engine. --stationary engine parts. --rotary engine parts. --reciprocating engine parts.
