DTSI stands for Digital Twin Spark Ignition. It works on the principle of twin spark produced by the two spark plugs. As compared with the single spark fired engines, in twin spark engines the combustion of the air-fuel mixture takes place at optimal level and it produces more power. Because of the use of twin spark plug, the spark produced is more which burns the fuel more efficiently and rapidly. It results in increase of mileage, power and less emission of exhaust gases. The Dtsi engine produces 26% more power as compared with conventional single spark engines of same capacity.
