4 Operation of two-stroke engine The two stroke engine employs the crankcase as well as the cylinder to achieve all the elements of the cycle in only two strokes of the piston. 360 degrees rotation of crankshaft completes the cycle. 5.

TwoStroke engine. As the name implies, a two-stroke engine is a type of internal combustion (IC) engine that produces work in two strokes (i.e., up and down moment) of the piston. The piston travels up and down once, i.e., one revolution of the crankshaft, to complete its power or thermodynamic cycle. The history of these engines dates back to Theengines used for the main propulsion or turning the propeller/s of the normal ships are usually slow speed 2-stroke engines while those used for providing auxiliary power are usually 4-stroke high speed diesel engines. You can see both these types of engines in the pictures below, the first figure being that of a 2 stroke main propulsion

2stroke cycle = 2 stroke of the piston in one cycle. = One Compression stroke and One Power stroke. = Piston going up + piston going down. = One complete revolution. > Compression Stroke. When the piston goes downward exhaust valves open up and the scavenge port is uncovered which allows the fresh air to enter through the scavenge port

Clarification In a two stroke engine, the working cycle is completed in one revolution of the crankshaft. 2. A two stroke cycle engine gives _____ the number of power strokes as compared to the four stroke cycle engine, at the same engine speed. 30 kW two stroke diesel engine running at 750 r.p.m d) 30 kW four stroke diesel engine running Thetwo-stroke engine is a reciprocating engine in which the piston does reciprocating motion (two-time movement) ( i.e. from TDC to BDC and BDC to TDC ) to produce a power stroke. Two-stroke engines are mainly used in two-wheeler vehicles like motorcycles. Compared with four four-stroke engines, the two-stroke engine produces more power.

Powerstroke takes place in every two strokes one power stroke for one revolution of the crankshaft. 2. Due to more ideal strokes and non-uniform load on the crankshaft heavier flywheel is required. 2. The engine has a more uniform load as every time Piston comes down it has a power stroke as such a light flywheel is necessary. 3.

Theearliest two-strokes were of the uniflow type. With this design, the fuel/air mixture is forced into the cylinder by a rotary blower ( supercharger) driven by the engine.There is no inlet valve: instead, there is an elongated hole, called a port, in the side of the cylinder near the bottom of the piston's stroke.The port is opened or closed as the piston passes up ItwtO2Y.
