What is DTS-i Technology, What is DTS-Si Technology?

Monday, March 16, 2009 Leave a Comment

DTS-i and DTS-Si are Bajaj Auto exclusive technologies in India. DTS-i was first introduced in the Pulsar 150/180 models in 2003. The DTS-Si technology came in the XCD 125 in 2007 and currently also available on Platina 125 and XCD 135.

What is DTS-i Technology?

DTS-iTo understand it one first needs to be familiar with the functioning of a Conventional 4 Stroke Engine (with single Spark Plug).

DTS-i stands for Digital Twin Spark Plug Ignition. In simple words it means that there are 2 spark plugs in the single cylinder engine and the timing of sparkplugs are controlled by a digital microprocessor.


The big difference between a conventional 4 stroke engines and the DTS-i engine is the incorporation of 2 Spark Plugs. The 2 spark plug set up leads to better burning of the air fuel mixture, which results in delivering better fuel efficiency without any compromise in power.


Benefits of DTS-i Technology

With a DTS-i engine, one gets the dual benefit of good fuel coupled with good power as well.

The evidence of the effectiveness of this technology is clearly demonstrated by the eagerness of other manufacturers like Royal Enfield, which have launched a model, the Thunderbird “Twin Spark”.




What is DTS-Si Technology?

The DTS-Si stands for Digital Twin Spark Plug Swirl Induction.

DTS-Si

Like the DTS-i engine, the DTS-Si engine also has 2 Spark Plugs, the timing of which is controlled by a Digital Microprocessor. The difference between these two engines is the offset position of the inlet and outlet ports of the DTS-Si engine. This offset position creates turbulence of the air-fuel mixture inside the engine.


Benefits of DTS-Si Technology: This enhances the fuel efficiency of the engine even further.

    Good Technology , hpe it is emerged from Indian Brain or it is usual like German Brain?????

    Any way we Indians can be proud of Bajaj and its latest Technology.

    .make more models of scooters like sym yamaha kymco with dtsi tech.

    Though it seems excellent explanation, there is no clarity given on turbulence flow... When Inlet and outlet ports are offset how turbulence flow will generate. Tthat need to be defined properly. pl help me if any one knows abu this............

    Due to the offset of the inlet & exhaust port (may not be in same axis like earlier system when seen from the TOP angle),the air fuel mixture directly hits the cylinder walls will create the spin inside the chamber will be charged with ignition(TWIN SPARK) will give the maximum burn of the mixture also efficiency.Hope i clarified..DAAMO.
