2 Overview Looking into: The Engine 1 The Internal Combustion Engine 2 The inside of the engine 3 Applications in life

3 The Internal Combustion Engine What is an engine? 1

4 The Internal Combustion Engine the combustion of a fuel which occurs with an oxidizer (usually air) In the combustion chamber expands Applies direct force on Adapted: AA1Car.com

5 Some engines……

6 2 The inside of the engine Peering deeper into the engine……

7 The inside of…… The Engine.

8 The basic 4-stroke configuration.

9 2-stroke engine One revolution of the crankshaft -up and down stroke of the piston Makes use of -beginning of compressions stroke and ending of combustion stroke to perform -the intake and exhaust functions simultaneously One revolution of the crankshaft -up and down stroke of the piston Makes use of -beginning of compressions stroke and ending of combustion stroke to perform -the intake and exhaust functions simultaneously Provides an extremely high specific power. Uses of 2-stroke engines In a minibikeTo power a generator

10 6-stroke engine More complex than 4- stroke engine -to make it more efficient and to reduce emissions Makes use of -captured heat from the 4- stroke cycle to power -an additional power and exhaust stroke of the piston in the same cylinder More complex than 4- stroke engine -to make it more efficient and to reduce emissions Makes use of -captured heat from the 4- stroke cycle to power -an additional power and exhaust stroke of the piston in the same cylinder

11 Wankel engine Makes use of -a rotary design to convert pressure into a rotating motion instead of using reciprocated pistons. to perform -a 4-stroke cycle within it Makes use of -a rotary design to convert pressure into a rotating motion instead of using reciprocated pistons. to perform -a 4-stroke cycle within it For its compact size, its design delivers a high-rpm (revolutions per minute). Also, it is simpler and lighter with less moving parts than a piston engine Uses of Wankel engines In the Mazda A Wankel engine In a Mazda RX-8

12 Inside The Engine Internal combustion piston engine Components of a typical, four stroke cycle, internal combustion piston engine. E - Exhaust camshaft I - Intake camshaft S - Spark plug V - Valves P - Piston R - Connecting rod C - Crankshaft W - Water jacket for coolant flow Reciprocating engine (piston engine) Pistonless Rotary engine -Uses one or more rotors (rotary pistons) -Unlike a normal reciprocating engine, it does not use pistons A example of a Pistonless Rotary engine is the Wankel engine -Uses one or more rotors (rotary pistons) -Unlike a normal reciprocating engine, it does not use pistons A example of a Pistonless Rotary engine is the Wankel engine

13 3 Applications in life How do engines benefit our society?

14 In today’s modern world, transport is especially important. Fast transport is necessary. In the old days, land transports comprised of horses and bullock carts. Sea transport was by the manual-rowing of a boat. Air transport did not exist. However, how fast can these forms of transport go? Without engines, how would the people of today carry out their livelihoods? Overseas business trips would require one to embark on a journey several days long on a boat which is rowed manually. Short trips would still take a much longer time on horses and bullock carts. Engines play an important role in today’s society

15 However, in today’s modern world, technology has proven to us that it can aid us greatly in our lives. The engine has come into our lives. Engines are the source of power to power fast transports like cars and ships. In addition, engines have sparked the birth of air transport, a new phase of transport which brings us around the world at a much faster speed. Engines also lighten our work. They power machinery which replaces lots of manual labour. They are indeed more efficient. All in, engines have played an integral part in the building of today’s modern and sophisticated society.
