D T S
In a conventional single-spark-plug-equipped combustion chamber, and the rate of combustion is relatively slow. The spark plug, usually situated at one end of the combustion chamber, ignites the air-fuel mixture and the ensuing flame spreads like a slowly inflating balloon. There is an inevitable delay for this inflating balloon to reach the furthest part of the combustion chamber. So, there are pockets of poor combustion within the chamber and, overall, the combustion is slow and inefficient.

when burning lean air-fuel mixtures, the two plugs provide rapid combustion, but at light loads, opportunity exists to further improve the combustion quality. Usually under such conditions, the quality and concentration of the air-fuel mixture will vary from one area to another within the combustion chamber. However, combustion efficiency in lean air-fuel mixture conditions can be further improved by generating high turbulence in the combustion chamber.
When high turbulence is generated and combustion takes place, the surface of the ballooning flame front fragments itself, with projection like fingers, and this increases its surface area, thereby improving combustion further.

The DTS- i is the mother technology for the latest Digital Twin Spark–Swirl induction or DTS-Si technology.
Based on DTS-Si technology, the new engine is expected to give good mileage without compromising on performance.
The new engine with swirl induction is expected to give an amazing mileage of 109 km/l under ideal test conditions, which is higher than the mileage the current 100cc motorcycles offer.
