What is the DTSI and also give its function and working principle ?
DTSI is Digital Twin Spark Ignition.
In normal engines, there will be only one spark plug generating sparks at a regular interval. DTSI has twin spark plugs which create sparks alternately. This means that in a given time frame there will be double the nunber of sparks than in the normal engine.
now coming to how it helps the performance is that, when the fuel passes by the heart of the engine, it is burnt by the sparks so generated. As such, the first spark burns the fuel and the second spark burns whatevr residual fuel is left in that particle of fuel passing by thus ensuring that the engine derives more power without any part of the unburnt fuel passing by thru the exhaust. This also ensures that the pollution is reduced to the minimum.
