Pulsar 220F:

 DTS-i:

              A patented technology that has made Pulsar the most followed bike both on the road and in competition R&D labs.

At the heart of every Pulsar is one of the most sophisticated engine technology this country has ever built. The DTS-i System. A technological marvel that ensures maximum performance with the lowest consumption and emission levels possible. We will be more than happy to let a Pulsarmaniac like you, get to know the secret behind this breakthrough Pulsar technology.

                                                

                                              

Twin spark ignition:

           Normal ignition system has a single spark plug. The flame front created by the spark takes some time to reach the entire combustion chamber. Hence the burning of air-fuel mixture is slow and incomplete. 

In case of twin spark, two spark-plugs fire at the same time. This simultaneous firing and swirl of the air-fuel mixture results in complete combustion. This action is digitally controlled by the DTS-i system (namely the twin spark plugs, TRICS III and intelligent CDI)

                                                  

                                                 

TRICS III:

             Power and torque requirements constantly change, depending on whether the rider is cruising, accelerating or is at high speeds/max speed. 

Throttle Responsive Ignition Control System - III is an intelligent system which can quickly adapt ignition timing to suit different riding characteristics. 

INTELLIGENT C.D.I.:

              The Intelligent Capacitor Discharge Ignition contains a microprocessor, which continuously senses different speeds and load on engine and responds by altering ignition timing. 

              Working together with the TRICSIII system, the microprocessor's memory provides optimum ignition timings for any given engine rpm, thereby obtaining the best combustion performance. 

EXHAUSTEC:

              ExhausTEC' is a device incorporated in the exhaust system. TEC stands for Torque Expansion Chamber. It is a tuned box (resonator) fitted onto the header pipe of the exhaust 

              In the lower rpm zones, the ExhausTEC helps to build a negative pressure pulse (vacuum) at the exhaust valve, thereby sucking in more air-fuel mixture into the cylinder during intake valve opening. 

                                             

                                                 

 4 VALVE:

            A typical 2 valve engine has just 1/3 combustion chamber head area covered by the valves, but a 4 valve head increases that to more than 50% area. Because of this flow area of intake & exhaust port / passages leading to valves also get increased. 

            This facilitates induction of more quantity of charge (air-fuel mixture) and also evacuation of all burnt gases inside the combustion chamber ensure faster, cleaner & more efficient combustion. This engine has 2 intake & 2 exhaust valves compared to 1 Intake & 1 exhaust Valve of a 2 valve engine. These valves are smaller & light weight compared to that of 2 valve engine. 4 Valves (2 Intake & 2 exhaust valves) are introduced to improve breathing means - intake & exhaust process of engine.
