Default Next-gen Bajaj Pulsar to get Variable Valve Actuation

According to a media report, the next-generation Bajaj Pulsar will get a brand-new engine with Variable Valve Actuation. Now, we have seen a similar system in other motorcycles before and it may not sound revolutionary. However, in the case of Bajaj, it's the implementation of this system that's unique.

Unlike most variable valve actuation systems that use complex and expensive setups, Bajaj has developed a simpler system that uses an electric motor to control the different cam profiles.

It's quite an ingenious setup that uses a camshaft with a sliding lobe drum and a slider mechanism that's operated by a lead screw. This in turn is operated by an electric motor. The slider mechanism moves a pin that switches the cam profile.

The CAD drawings of the engine you see here has three settings that would change the valve lift and timing, depending on the riding style. The system would use sensors to detect the engine rpm and other parameters to select the optimal cam profile.

This Variable Valve Actuation system is expected to debut on the Pulsar 250F. It might also be implemented in smaller capacity engines.

Default Re: Next-gen Bajaj Pulsar to get Variable Valve Actuation

Perhaps this technology might be used for the Triumph Bajaj lovechild in the making, be anyone's guess. Great to see Bajaj always taking the first-mover advantage in bringing excellent tech to masses at affordable prices. Great move by Bajaj, after the KTM stake. Other brands have a helluva lot of following up, catching up and whatever they need to get it up.

Cheers!
