The Bajaj Pulsar 220 DTS-Fi from Pulsar family of motorcycles from Bajaj Auto was produced between 2007 and 2009 when it was replaced by the Pulsar 220 DTS-i. Features differentiating this bike from other members of the DTS-i family include oil cooled, fuel injected engine, front and rear disc braking, tubeless tyres, a digital speedometer console (recently introduced in all other Pulsar editions) and parabolic/ellipsoidal projector headlamps.
Bajaj displayed the 220 DTS-Fi at the Delhi Auto Expo 2006. The Indian nationwide launch happened in July 2007.
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.[1][2] 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 (15 kW) and a maximum torque of 19.12 N·m (14.10 lb·ft).
Engine technology
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 In fuel injection, the conventional carburettor has been replaced by injector which injects fuel in to the engine in a spray form based on the instructions of the Engine Control Unit (ECU) which is a part of the Engine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.
Successor
A new Pulsar model, the 220 DTS-i which has a constant-velocity carburetor instead of fuel injection, is the successor to the fuel injected 220 DTS-Fi.[3] DTS-Fi production and distribution was halted in 2009.
