What is DTSi Technology?
DTSi stands for Digital Twin-Spark Ignition.
How Does Digital Twin Spark Ignition Work?
Digital Twin Spark Ignition is a trademark patented by Bajaj Auto (http://www.bajajauto.com). Bajaj Auto implemented in its Avenger & Pulsar models. This technology helps in saving fuel and improving engine performance. Bajaj developed the Digital Twin Spark ignition (DTSi) technology. Besides, Bajaj had incorporated it in many of its current engines.
As claimed by Bajaj Auto, Digital Twin Spark Ignition uses two spark plugs. They ignite the air-fuel mixture at the same time in the Twin-Spark technology. This simultaneous firing of the spark and the swirl created in the air-fuel mixture result in the complete burning of fuel. This action is controlled digitally (electronically) by the Digital Twin Spark Ignition system.
About The Technology:
In a conventional combustion chamber with a single spark plug, the rate of burning of the air-fuel mixture is relatively slower. The spark plug is normally located at one end of the combustion chamber. When it ignites the air-fuel mixture, its flame spreads like a slowly inflating ball. Thus, it results in some delay for this fireball to reach the farthest point of the combustion chamber. So, this creates some areas of poor combustion inside the combustion chamber. Hence, generally, it results in slower and inefficient combustion.
Moreover, the DTS-i not only takes care of the slow rate of combustion but also improves it further. The DTS-i engine has two spark plugs in place of the typical one. These twin spark plugs generate two sparks at opposite ends of the combustion chamber. It is approximately 90° to the valve axis. Thus, the air-fuel mixture ignites in such a way that it creates two fronts to the flame.
Furthermore, it results in a reduction in flame travel to up to 40 percent. This leads to faster combustion, which raises the combustion pressure rapidly. Ultimately, it helps the engine deliver more torque and better fuel efficiency. Besides, it also helps lower emissions and smooth engine functioning.
