Features and specifications
With this introduction, Bajaj Auto would achieve a close second in the race to offer a microprocessor-based fuel injected motorcycle to Indian customers, after Hero Honda's 125 cc Glamour FI motorcycle.The new Pulsar has a longer wheelbase than its predecessor, factory-fitted front and rear disc brakes and detailed digital instrumentation. The Pulsar DTS-Fi generates a maximum power of 20 bhp and a maximum torque of 19.12 N·m (14 lb·ft).
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 In fuel injection the conventional carburettor has been replaced by injector which injects fuel in to the engine in a spray form based on the instructions of the Engine Control Unit (ECU) which is a part of the Engine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 fueling 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 fueling & 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.
