Two-Wheeler Engine Technology | DTS-i | HET | APDV | ASFS | SEP | i3s | DTS-Si | ATFT | BLUE CORE

You might have seen the words like DTS-i, HET, APDV, SEP, ATFT or i3s written on motorcycles or scooter. These words in actual are the names of advanced technologies patented by the motorcycle companies. These Motorcycle companies has developed many state of the art technologies over the past few years. These technologies have not only improved the performance but have also increased the sells volume. Some of these technologies have even become trade mark of these companies. Customers get attracted by the fancy names of these technologies without even knowing the real concept behind them.

Digital Twin Spark Ignition ( DTS-i)

The first innovation in the series of amazing motorcycle technologies is DTS-i. Digital Twin Spark Ignition or DTS-i is a technology patented by Bajaj Motors. It is being used on motorcycles like Pulsars and XCD 125. 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 one. These twin spark-plugs generate two sparks at opposite ends of the combustion chamber which are approximately 90° to the valve axis. Thus, the air-fuel mixture ignites in such a way that creates two fronts of the flame. It results in a reduction of 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, better fuel efficiency, lower emissions and smooth operation. The firing of sparks is controlled digitally by Engine Control Unit ECU. Twin sparks if used in 4 valve engines can deliver amazing performance.

DTS-Si Technology

DTS-Si means Digital Twin Spark Swirl Induction. This is an improved version of DTS-i Technology. This involved the optimisation of inlet port design, in order to create swirl in the supplied charge. This swirl helps in proper mixing of air and fuel.. This helps in quick flame propagation and hence better combustion. This technology is also patented by Bajaj Motors.

APDV Technology

The next amazing motorcycle technology is APDV. It stands for advance pro series digital variable ignition system. Basically, it is an electronically controlled ignition system used by Hero Motocorp in its 100 cc motorcycles. This technology promises better combustion, improved mileage and superior engine performance.

Advanced Swirl Flow Induction System (ASFS)

You might have noticed ASFS word written on hero motorcycles. It is another master piece in the list of amazing motorcycle technologies. It is generally used in 125 to 150 cc motorcycles. Its basic purpose is to create conditions suitable for proper mixing of air and fuel. ASFS stands for “Advanced Swirl Flow Induction System”.

Advanced Tumble Flow Induction Technology Or ATFT

This is a little improved version of ASFS technology. It is also patented by Heromotocorp and is used in their higher cc bikes. This technology focuses on improving particle to particle contact between air and fuel by preparing a better mixture.

I3S Technology

Idle Start Stop System or more popularly I3S is again a patented technology of Heromotocorp. With this technology the company claims to improve the mileage of their bikes. All the lower cc motorcycles of Heromotocorp are available with an option of I3S.

Honda Eco Technology (HET)

For increasing efficiency and boosting up the mileage, Honda came out with HET . This amazing technology focuses on a three fold approach. This approach is quite similar to Blue core technology of Yamaha with some minor differences. It focuses on reducing friction, improving combustion and optimizing the transmission.

Blue Core Technology

Blue Core Technology is implemented by Yamaha in its motorcycles. It works on four principals to increase efficiency and performance.

Suzuki Eco Performance Or SEP

Suzuki is famous for state of the art motorcycle technologies. Suzuki Eco Performance is developed by Suzuki specially for medium and small engines. SEP promises to provide fuel efficiency along with performance.
