Advantages and Disadvantages of Two-Stroke Cycle Engine

Advantages and Disadvantages of Two-Stroke Cycle Engine Points : Advantages and Disadvantages of Two-Stroke Cycle Engine, Advantages and Disadvantages of Two-Stroke Cycle Engine Over Four- Stroke Cycle Engine Advantages

1. It requires less spare parts due to its easy design.
2. There is a economy in work necessary to overcome the resistance of inlet and exhaust ports.
3. The rotating minute on the crankshaft is additional even in two-stroke cycle engine due to one working stroke for every revolution of the crankshaft, and so a lighter flywheel is necessary in it.
4. It has elevated mechanical competence due to the lack of cams, crankshaft and rockers, etc., of the valves.
5. It can be simply reversed if it is of valve less kind.
6. For the similar power, a two-stroke cycle engine is additional dense light and requires less space than a four-stroke cycle engine. So, it is additional right for auto cycles, motor cycles and scooters.

Disadvantages

1. To real density starts while the ports are totally closed by the up movement of the piston, following a little degree revolt of crankshaft.
2. It gives better noise.
3. The accuse is diluted by the burnt gases due to unfinished scavenging.
4. In two-stroke series Otto engine, the fuel use is high because the fresh charge is probable to be exhausted by evasion during the exhaust port.
5. There is a better wear and tear of moving part,
6. It consume more lubricate oil.
