Classification: CPC G  B | IPC B  G

Claim 0:
1. A portable self-contained test system for measuring emissions of an engine, comprising:
a structural assembly forming a plurality of component mounting positions;
a heated sampler mounted in said structural assembly and having an input connector adapted to receive a line carrying exhaust from the engine to the heated sampler for testing;
a Fourier-transform infrared spectrometer mounted in said structural assembly and connected to a gas output of the heated sampler;
a plurality of testing gas sources mounted in said structural assembly and connected to the heated sampler via electrically actuated valves to selectively provide testing gases to the heated sampler;
a programmable control device connected to said valves, comprising a program that automatically electrically controls said valves in a predetermined sequence to perform a series of emissions measurements;
a computing device connected to said spectrometer and containing software that receives test data and analyzes said data to produce a standardized emissions test report as an output; and
a portable electrical power source mounted in said structural assembly and connected to provide power to said spectrometer, said valves, said programmable control device, and said computing device, said source providing sufficient power to maintain operation of the connected devices for the duration of a complete standardized emissions test;
wherein the structural assembly is arranged and sized so that the system contained therein can be delivered to a test site on a truck, removed from the truck and placed in position proximate to the engine requiring emissions testing, and left there for the duration of the emissions test.
