What is ExhausTEC?
For - Improved low and mid-range torque of the engine. By - Bajaj Pulsar
How does Exhaust Torque Expansion Chamber work?
The Exhaust Torque Expansion Chamber device fits in the exhaust system of Bajaj Pulsar. Thus, it is a resonator (or a tuned-box) that fits onto the header pipe of the exhaust. According to Bajaj Auto, this technology improves 'scavenging,' which is the process of pushing the exhaust gases out of the cylinder.
Furthermore, Bajaj Auto claims that the system helps to build negative pressure or vacuum at the exhaust valve in the lower rpm zones of the engine. And, it eventually results in sucking more air-fuel mixture into the cylinder during the opening of the intake valve.
Thus, it improves the low and mid-range torque of the engine. Bajaj Auto developed this technology and implemented it in its Pulsar models.
