Portable Gas Analyser for Petrol Vehicles

[akuldgshds]

Dear Sir,

I’m doing a project regarding Low Cost Portable Auto-mobile Gas Analyser for Petrol Vehicles. I wish to measure the hydrocarbon, carbon monoxide, carbon dioxide levels and temperature and RPM of the engine. I would like to know what sensors to use and if anyone has a circuit diagram this would be very much appreciated.

1) Should I use Infrared type gas sensor ?
2) If u know any link to get proper idea about this please let me know.

Thank U,
akuldgshds.

Put this phrase in Google:

automobile exhaust gas analyzer

Then go here:

http://en.wikipedia.org/wiki/Gas_detector

You will find good explanations and many, many, many machines for sale. Read their specifications, you will learn how others measure those items. Then you can design a lower-cost way to do it. Designing your own gas sensor is very complex. A circuit diagram is not something we can share.

Here are a couple of existing products:
