Abstract: The invention is directed to an improved mass emissions measuring system (15) for an internal combustion engine (17). In the preferred embodiment, the system is comprised of a particulate monitor (16), four sensor (18, 22, 23 or 29) which may be temporarily attached to the engine for sensing operating parameters of the engine, an engine-control interface (21), a processor (19) programmed to collect and manipulate data from the monitor and the sensors and/or engine-control interface, a display (20) for displaying the particulate emissions of the engine, an exhaust sampling system (31) which is adapted to be temporarily connected between the exhaust system of the engine and the particulate monitor, and an opacity meter (56 or 58).

Abstract: The invention is directed to an improved portable on-board mass emissions measuring system for internal combustion engines. In the preferred embodiment, the system is comprised of an exhaust analyzer (16), at least one sensor (18, 22 or 29) which may be temporarily attached to the engine for sensing parameters of the engine, and a processor (19) programmed to collect and manipulate data from the analyzer and the sensor, whereby the mass emissions of the engine may be calculated. The system may further comprise a display (20) for displaying the mass emissions of the engine and an engine-control interface (21). The sensor may be capable of sensing engine RPM, engine oil temperature, or intake manifold pressure. The exhaust analyzer may be capable of measuring concentrations of the engine exhaust constituents, particulates, aerosols, and gases in the engine emissions.
