Claim 10:
11. A method for performing an emissions test for an engine operating at a fixed location, comprising the steps of:
providing a portable, self-contained emissions test system comprising a structural assembly having mounted therein a heated sampler with an input connector, a Fourier-transform infrared spectrometer connected to a gas output of the heated sampler, a plurality of testing gas sources connected to the heated sampler via electrically actuated valves, one or more computing devices with programs that automatically electrically control the valves and spectrometer to perform at least one standardized emissions test and provide a test report as an output, and a standalone electrical power source connected to provide power to components of the system for the duration of said emissions test;
delivering said test system to a testing site on a truck;
removing the test system from the truck and placing the test system in a position proximate to the engine to enable monitoring engine emissions;
connecting the input connector of the sampler to the engine exhaust using a heated sample line;
while the self-contained test system is in position, initiating one or more automated standardized emissions tests using the test system; and
upon completion of the test, removing the test system from its position and loading the test system onto the truck for transportation to another site.
