Bikes are one of the top-preferred transportation modes because they offer ease of navigation in the ever-increasing traffic on Indian roads. There are so many different bikes available in the market that making the right choice becomes tough. One of the things that you need to consider while you purchase a bike for yourself is the engine technology that has been installed in the bike. A good engine technology ensures that your bike offers you a premium riding experience while also saving the environment.
One of the technologies that people are preferring is DTSi technology. It is considered to be one of the revolutionary bike engine technologies because it combines a powerful engine with fuel efficiency and lesser harm to the environment. Before we get into the details like the DTSi full form and what is the DTSi engine, there is another aspect of buying a bike — a two-wheeler insurance plan.
Driving on Indian roads without valid third-party two-wheeler insurance is illegal as per the law. So, ensure that you at least have a third-party bike insurance plan. A comprehensive bike insurance plan, however, can offer you all-around protection from various mishaps that can occur on the roads.
Tata AIG offers different two-wheeler insurance plans to suit your needs. You can choose the plan after researching and comparing the different plans. Also, if you think that remembering to renew your bike insurance plan yearly is a hassle, you can choose the long-term two-wheeler insurance plan with which you can insure your two-wheeler for 2 or 3 years.
What is the DTSi Engine?
DTSi is an engine technology developed and later patented by Bajaj Auto Limited. The DTSi full form is Digital Twin-Spark Ignition System. The technology first came into use in Avenger and Pulsar models produced by the company. When the technology was launched in the market, it was considered to be quite revolutionary because not only did it reduce fuel consumption but it also improved the performance of the engine.
In automobile engineering, achieving perfect combustion is next to impossible because losses occur in the bike's combustion chamber. This is because of the design of the internal combustion engine, where the burning of fuel does not take place instantaneously. However, the unique DTSi engine attempts to make complete combustion happen by making the process of combustion as quick as possible.
This engine produces twice the amount of power of a simple two-stroke engine and also provides a considerable power boost. It also has a great ratio of power-to-weight in comparison to some of the 4-stroke bike engines. The DTSi engine has the ability to adjust the idling speed and also cuts the fuel feed off when the throttle of the bike is released. Thus, this leads to control of the enrichment process of a mixture of air and fuel for acceleration and cold starts. This is the DTSi meaning.
Moreover, it ensures that the upper limit of the rev is not reached. At the lower revs, the boost is enabled, which gets cut out when it is not being used to overtake. At more speeds, the over boost helps in the full delivery of power and this will be enabled till the throttle of the bike is open.
How Does Digital Twin Spark Ignition Work?
The DTSi system of the bike uses two different spark plugs for the ignition of the mixture of air and fuel alternatively. This is to enhance the flame diameter and cause the fuel to burn instantaneously. The whole process of firing this spark, along with the swirl that is caused inside the mixture of air and fuel causes incomplete combustion. The DTSi engine electronically controls this whole process.
The two different spark plugs are placed on the different ends of the bike’s combustion chamber, leading to speedy and efficient combustion. The whole system is electronic and includes a static spark advance and there are no moving parts, so there is no occurrence of any wear or tear. This whole system is charted by the bike’s integrated digital electronic box that is also in control of the fuel injection and the timings of the valve.
There are two plugs for every cylinder and the piston heads and combustion chambers are positioned in a way that they produce a fast and broad flame in order to cause an ignition in the air and fuel mixture. The DTSi technology enables leaner mixtures and lower ignition advance and thus allows the provision of a powerful yet lightweight engine.
Top Features of the Digital Twin-Spark Ignition System

Benefits of the DTSi Engine
The DTSi engine has various benefits. Some of the benefits are listed below.
Engine parts are not subjected to wear and tear and thus have a better life span. Thus, you will not have to for the replacement of parts like valve stems and piston rings. Buying a DTSi engine bike will reduce your costs.
Better comfort levels and handling due to lesser noise and fewer vibrations in the engine of the bike. The Digital Twin-Spark Ignition System promises a smoother ride than some of the other bikes in the market.
The specific consumption of fuel is lower thus the bikes with the DTSi engine have better mileage than some of the other bikes in the market.
There is no overheating of the engine, thus you can take long rides on your bike without worrying about any discomfort.
The thermal efficiency of the engine of the bike is higher.
Due to the enhanced power of the bike, it can take higher loads with ease.
Due to the higher ratio of compression, the bike will be able to start easily in low temperatures, winter season, and cold weather. This means that there is no worry about your bike not being able to start when the weather is extremely cold.
The DTSi technology enhances the flame’s diameter which causes instant combustion of the fuel, which leads to a better output of work because of the increased work that gets exerted on the bike’s piston.
Enhanced and increased throttle response.
Resistance to temperature fluctuations and breakdowns, making the bike more sturdy and dependable for different commute purposes.
The Digital Twin-Spark Ignition System ensures that the bikes are powerful while still being fuel efficient. They also reduce the emission of harmful gases into the air which helps to reduce the pollution caused by the bikes. If you plan to buy a bike for yourself, you can consider buying a bike with this technology so that you can save on fuel expenses, get a smooth ride experience, and also contribute to saving the environment.
While you purchase a bike for yourself, do not forget to buy the right insurance for the bike. A third-party bike insurance plan is mandatory as per the law so ensure that you have a valid plan otherwise it can lead to penalties. So, ensure that you have the right bike insurance plan from Tata AIG and ride your bike on the road without having to worry.
