ABSTRACT
The object of developing a Digital Twin Spark-Swirl induction (DTS-Si) technology is to provide a better mileage to vehicles without compromising the performance of the vehicle. Usually better performance vehicles don’t have a better mileage and better mileage vehicles aren’t able to give a better performance. The objective is to develop an engine which delivers good mileage and good performance at the same time.
In former technologies only one spark plug was used. The use of one spark plug didn’t make the combustion process instantaneous and it didn’t ensure complete combustion and fuel benefits.
When the cylinder head is equipped with two spark plugs, instead of the usual one the two sparks at either ends of the combustion chamber, (approximately 90° to the valve axis) the air-fuel mixture gets ignited in a way that creates two flame fronts and, therefore, a reduction in flame travel of the order of 40 per cent is achieved. A fast rate of combustion is achieved leading to faster rise in pressure. The obvious outcome of this is more torque, better fuel efficiency and lower emissions.
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. So the objective of developing a DTS-Si is to overcome these faults of a single spark plug equipped combustion chamber.
