dtsfi means"digital twin spark fuel injection "..
there is no any practical deta available presently..
only bajaj company going to launch a bike ,which have DTSFI system.
this bike is knon as PULSER 250 DTSFI.the company still not disclose any data about the product..

DTSFI means Digital Twin Spark Fuel Injection. The engine using this technology will use 2 spark plugs which will ensure better combustion of fuel and hence better fuel economy and less pollution.

DTS-Fi stands for "Digital Twin Spark Fuel Injection", a ‘Bajaj Patented Technology’. In fuel injection, the conventional carburettor has been replaced by injector which injects fuel in to the engine in a spray form based on the instructions of the Engine Control Unit (ECU) which is a part of the Engine Management System EMS. The Electronic Control Unit (ECU) is microprocessor based and is the brain of the fuel injection system. It processes information sent by various sensors and instantly determines optimum fuelling and spark timing for various engine-operating conditions. The ECU contains detailed information of the engine's characteristics from which it picks the necessary data for commanding both fuelling & spark timing.

The main advantages of Fuel Injection are: a. Increased power output for same cc. b. Better low-end torque. c. Lower fuel delivery & optimisation of spark timing. d. Improved cold start, quick warm-up and excellent response to sudden acceleration. e. Lower emission levels. f. Self-detection and communication of fuel system malfunctioning if any.
