Conventional spark ignition engine have defects such as high exhaust emission, low power and efficiency due to incomplete combustion which occur during idling & at part load operations conditions. The introduction swirl chamber to the engine allows proper mixing of fuel & air giving complete control on combustion and emissions and thereby increasing power and efficiency. Another significant advantage of using swirl chamber is that it is economical too as it provides a correct estimation of the quality of fuel required at proper time & provides control over combustion. Swirl chamber is becoming an important option to further optimize internal combustion engine. Accordingly a system having swirl chamber type induction system has designed and developed.
