Twostroke engines have two types. First one is known as Spark ignition engine or better known as petrol engine, which works on Otto Cycle and other one is compression ignition engine or diesel engine, which works
Thefull form of the CI engine is a compression ignition engine. A CI engine is an internal combustion engine where the use of hot compressed air ignites the fuel. When air is compressed, heat is created, which is used to ignite and burn the fuel. In this engine, the suction stroke draws air in, which is then compressed during the compression Itcan be 2-stroke or 4-stroke (see diagram), but unlike spark-ignited spark-ignited engines, diesel engines introduce air into the combustion chamber only during the intake stroke. Diesel engines generally have compression ratios between 14 and 14. Engines with a bore (cylinder diameter) less than 600 mm can be designed as both 2-stroke and DieselCycle. This diesel cycle it also establishes the thermal behavior diagram for a 4-stroke or 2-stroke diesel engine. In this case, there are some particularities, to which must be added its higher compression ratio compared to gasoline engines. Therefore, the thermal efficiency in this case ranges from 30 to 45%.3 2 STROKE DIESEL ENGINE INTRODUCTION A two-stroke diesel engine is a Diesel engine that works by combining what is normally four cycles – intake, compression, combustion, and exhaust into only two strokes (one revolution) of the engine. It was inventedby Hugo Güldner in 1899. In a two-stroke engine, the end of the2stroke engine work consume little more fuel. Due to less number of parts two stroke engine are lighter in weight. 2-stroke engine has the power stroke then 4-stroke engine and as such develop more horsepower. For send more air in 2-stroke engine supercharger are used to that engine develop sufficient power. A 2-stroke
