How secondary air induction system works. ✔

[@TechTrixInfo]

yes what you have said is absolutely correct. it doesn't reduce pollution, i have uploaded another video on this topic which explains that, have a look.

Ok Great. You can visit our web site at techtrixinfocom and android app techtrixinfo from Google play.

yes correctly said, i believe you are much a technical person, please have a look at our other videos too and rate us. you can also connect with us on face book.

If only mixing of exhaust gas with fresh air reduce the pollution then why we need special unit for it when it carried out in atmosphere automatically

[@swarnalatha8046]

please explain how secondary induction system valves are working. you said due to pressure difference it happens. but how exactly it happens. as SIS is connected at both inlet and outlet. how air fuel mixture from carburetor is not getting disturbed by SIS. Please explain in detail.

U may need to update your explanation. Basic EGR (Exhaust Gas Recirculation) flows back into the cylinder chamber not out. In other words, about 5 to 15% I think flows back in with fresh oxygen and fuel mix to help reduce NOx (nitrogen oxide) emissions. Of couse this is the simple way of explaining it... modern engines (namely petrols) now have other ways of regulating the EGR flow as well as cooling it before being reused. This helps the engine be more efficient with power strokes and fuel use.

Maybe in car. Indian bike it doesn’t go back to cylinder

Secondary air filter _purge unit or purge valve how it works can you show me a practical example or demonstrate its actual working of Honda activa, I want service that unit of my vehicle it will be much more useful for my work on activa. Thanking you

[@Nazmulsaidi]

Please work on your last part of your explanation. Its not right. You never mention what happens in catalytic converter with this air.

thanks bro

Secondary air induction has no connection to the inlet port. It operates with a reed valve between the air box and the exhaust port and an vacuum or electric valve to have the system active at idle or when engine is cold to induct air into exhaust supporting burning of unburnt fuel in this situations. I believe the drawing is wrong.

Please learn more on the system, before you teach some body else, dear !

[@NPOSK]

It is crap. when piston sucks air and fuel mixture, the exhaust gas also get sucked. Sending carbon monoxide back to the combustion chamber.

[@Nazmulsaidi]

It doesn’t suck exhaust. There is a reed valve connected in exhaust side piping
