Question Exhaust emissions

Does anyone know of a site to obtain a list of emissions in car exhast for a gasoline engine. We make a device to measure methane in low (ppm) concentrations and need to determine if car exhaust will interfere with the measurement.

Thank you

If the engine is running properly, I don't think there should be any methane at all. Of course there is no such thing as an ideal engine, but I think the biggest problem would be if the engine isn't running correctly, and then I can't imagine there is any precise documentation of a poorly running engine?

Just thinking out loud...
