In this system, due to twin sparks, combustion will be complete. It is a means of controlling the Ignition by operating the Throttle.
The Double Spark Plug Technology was proved good for better low end torque and greater fuel efficiency in automobiles but arranging space for two spark plugs became difficult even in multi-cylinder big sized engines with 4 valves, hence the Europeans could not afford to risk their engines for the leak in compression and eventually engine failure by stacking 4 valves and 2 spark plugs together in a comparatively small sized engine head.
A microprocessor continuously senses speed and load of the engine and respond by altering the Complete history of dtsi engine timing there by optimizing power and fuel economy.
It is located at opposite sides of combustion chamber. Ignition with a Digital C. While that sounds logical and simplistic, TVS Motor claims that the same effect is achieved by employing a single spark plug with differential sparking cycles.
In a conventional combustion chamber with single-spark-plug, the rate of burning of the air-fuel mixture is relatively slower. This leads to faster combustion which raises the combustion pressure rapidly. So, this creates some areas of poor combustion inside the combustion chamber. Mercedes-Benz was also among those who have used the technology in their cars.
At higher speeds the over boost will enhance full power delivery and will stay on as long as the driver exercises maximum pressure on the accelerator. Alfa Romeo was the first automaker to use the dual spark plugs in their engines, first in their racing cars and there after in the passenger cars, followed by many other car makers of the World.
Detonation in DTS-i engine Thus, the air-fuel mixture ignites in such a way that creates two fronts the flame. Depending on the needs of the Rider whether it be cruising, acceleration or max speed, the ignition requirements constantly change.
That is the reason why even car manufacturers are refrained from this technology as it has a serious threat of jeopardizing the engine reliability. Alfa Romeo had a problem with one of its cars of rough low speed running and poor low speed fuel economy, they found that due to the long Bore of the engine the flame from the spark plug could not reach to the air and fuel mixture in the combustion chamber properly and hence the combustion was not taking place completely and efficiently resulting the unburnt fuel residue expelled out from the exhaust making the engine not only polluting but also poor fuel economic.
This simultaneous firing of the spark along-with the swirl created in the air-fuel mixture results in complete burning of fuel. This action is controlled digitally electronically by the Digital Twin Spark Ignition system. I am sure at least once all such questions and many more must have also come in your mind, lets go through the insight of "Multiple Ignition System" its significance in motorcycle engines, Advantages and Disadvantages of it.
Thus, it results in a reduction in flame travel to up to 40 percent. At low revs, the over boost is mostly used when overtaking, and this is why it cuts out automatically.
A fast rate of combustion is achieved leading to faster rise in pressure. It features two plugs per cylinder. Monday, 9 September DTSI Digital Twin Spark Ignition System It is very interesting to know about complete combustion in automobile engineering, because in actual practice, perfect combustion is not at all possible due to various losses in the combustion chamber as well as design of the internal combustion engine.
Hence, generally, this results in slower and inefficient combustion. This innovative solution, also entailing a special configuration of the hemispherical combustion chambers and piston heads, ensures a fast, wide flame front when the air-fuel mixture is ignited, and therefore less ignition advance, enabling, moreover, relatively lean mixtures to be used.
It is mapped by the digital electronic control box which also handles fuel ignition and valve timing. Decrease in the specific fuel consumption No over heating Gradual increase in the pressure hence power is uniformly distributed throughout the crank angle and hence smooth ride.
The DTS-i engine has two spark plugs, in place of the typical one. Digital twin spark ignition technology powered engine has two spark plugs. The ignition system on the Twin spark is a digital system with static spark advance and no moving parts subject to wear.
When it ignites the air-fuel mixture, its flame spreads just like a slowly inflating ball. This is overcome by the DTSi by having 2 spark source on the opposite sides which reduces the flame travel as stated above.
Originally use of Twin Spark Plug per cylinder was seen in aircraft engines. There is an inevitable delay for this inflating balloon to reach the furthest part of the combustion chamber.
As claimed by Bajaj Auto, Digital Twin Spark Ignition uses two spark-plugs to ignite the air-fuel mixture at the same time in the Twin-Spark technology. This helps in achieving a good balance between driveability and Optimum Ignition Spark advance, resulting in an almost perfect Ignition Spark advance for every Throttle opening and Engine rpm.
How Does It Works? The technology was primarily invented for safety purpose in aircraft, it provides redundancy in case of ignition failure while airborne, as if one spark plug or its ignition system gets failed the other spark plug will be suffice to keep the engine running and helps to land the aircraft to its safety.
Please do share what is your experience with this technology and what do you think about the same. Putting up dual spark plugs per cylinder is not new, it is as old as World War I technology.
This DTS-I technology will have greater combustion rate because of twin spark plug located around it.DTSI (Digital Twin Spark Ignition System) It is very interesting to know about complete combustion in automobile engineering, because in actual practice, perfect combustion is not at all possible due to various losses in the combustion chamber as well as design of the internal combustion engine.
