How Does an Autochoke Work?

Having read your shootout comprising the TVS Ntorq, Aprilia SR 125, and the Honda Grazia, I decided to buy the Ntorq. I have had no cause for regret so far because the scooter is quite excellent. What baffles me, though, is that there is no choke. I asked the people at the dealership and they said that the scooter comes with an auto-choke. Can you please explain how this works and what its benefits are? Priyam Bagga, New Delhi Hello, Priyam, Congratulations on your new acquisition! As for your query, what the dealer told you is correct; the Ntorq, among other TVS scooters, comes with an auto-choke. A sensor in the scooter detects if the choke is needed and automatically adjusts the air-fuel mixture to make it richer in order to help start seamlessly during a cold start. The advantage of this is that you don’t need to make the effort of activating the choke and don’t need to worry about remembering to turn it off once your scooter is running smoothly. The disadvantage is that you cannot manually regulate the application of the choke so it may run on a richer fuel mixture for a little longer than you may have opted for, causing your scooter to possibly consume a little bit of extra fuel.
