Introduction A conventional 4 Stroke engine has a Single Spark Plug and leads to inefficient combustion. Required Basic design for i)Uniform power delivery in all operating conditions. ii)A high degree of drivability.

So , What is this DTSI ? ? Two spark plugs at opposite ends of combustion chamber. Hemispherical chambers, piston heads. Helps in better fuel efficiency and lower emissions.

Main Characteristics Digital electronic ignition with two plugs per cylinder and two ignition distributors. Twin overhead cams with camshaft timing variation. Injection fuel feed with integrated electronic twin spark ignition.

Maiden DTSI First 4 -wheeler to use DTS-i. Designed to achieve 1. peak torque. 2. Superior power output Cylinder capacity -1, 962 cc Bore -84 mm Stroke -88. 5 mm Compression ratio 10: 1.

Engine comprises of……. ? ? ? Four-in-line cylinder Light weight due to all Aluminium -alloy. The pressed-in cast iron cylinder liners for more effective heat dissipation.

Valve Drive Valves directly acts in Vconfiguration. Valve timing Actuator operates exhaust and intake valves. At high and medium-high engine speeds, cylinder filling is optimal.

Advantages Better starting of engine even in Winter season & cold climatic conditions. Due to two spark plugs, there will be sufficient time intervals to cool the chamber. Efficiently balances the temperature of chambers and other parts.

Advantages Increase the Thermal Efficiency of the Engine. Diameter of the flame increases rapidly. Twin Spark plugs reduces the soiling of plugs.

Ignition It is controlled by integrated digital electronic control box called Capacitor Distributed Ignition(CDI). DTS-i yields: 1. More effective combustion at low load and at idling speed. 2. A sizeable reduction in specific fuel consumption. 3. Less chance of ignition system failure.

Disadvantages The engine tends to overheat and loose power at higher speeds. Requires more investment for replacing the plugs. The engine wear and tear is somehow increased and hence these engines need frequent checkup.

So, finally I conclude…. . Perfect Combustion in Internal Combustion engine is not possible. DTSI system helps for instantaneous burning of fuels. To overcome the requirements, new patent DTS-i is introduced.
