Smoke Opacity Meter for real-time monitoring of diesel engine’s exhaust stack emissions (on the meter’s integral LCD) with output for simultaneous data capture and display via optional DYNOmite data-acquisition computer and DYNO-MAX. Adjustable stack-mounted sensor adapts to most diesel exhaust stacks. Integral 12-volt supply battery plus 120-volt AC supply allows on-highway, or in-shop, testing. Analog output jacks and harness for connecting to DYNOmite-Pro data-acquisition computer with DYNO-MAX software.
Exhaust Measuring System five-gas analyzer for real-time monitoring of engines emissions during chassis or engine dynamometer testing. Large integral LCD panels. Simple user interface includes both manual and automatic zeroing, low-flow warnings, out-of-range detection, etc. five-gas analyzer includes O2 (0-25%), CO (0-10%), CO2 (0-20%), HCs (0-2000 ppm), and NOX (0-5000 ppm) readouts. Lambda and AFR are also calculated and displayed when using the (all digital) link to a PC running the optional DYNO-MAX software. (Requires an available RS-232 serial port and DYNO-MAX standard or “Pro” software). Integral vacuum pumps and water separator make the system compact and easy to maintain. Flexible stainless-steel tailpipe “sniffer” probe and 25' hose includes quick disconnect coupling. Less than five-minute warm-up time with typical accuracy of ±1% (or better) of full scale. Fast response time < 9 seconds to 90% of actual. 12-volt lighter plug DC operation allows the DYNOmite EMS to go on the road for real-world emissions monitoring (also includes 120-volt AC supply).
Air/Fuel Ratio Exhaust Sensor Module and harness for measuring the engine’s mixture on the dyno or road. Its ultra-wide 9 through 16 A/F Ratio range DYNOmite sensor is broad enough for high-performance gasoline-engine tuning. (Works with most pump fuels.) Sensors are individually offset-trim matched, so multiple sensors can be used for cylinder-to-cylinder comparison testing (with one switch-controlled module). Outputs include both a near-linear 0-5 volt analog signal (requiring no correction mapping over most of its working range) and an (all digital) RS-232 link to DYNO-MAX. The digital interface avoids the multiple analog conversion errors – common in other units! This system’s typical accuracy of ±2% (or better when near the stoichiometric ratio) and fast response time make it suitable for even many research laboratory grade, transient dynamometer test programs. Semi-automatic offset calibration in free air allows for easy field verification. (Requires available 0-5 volt channel and DYNO-MAX software.)
Air/Fuel Ratio Exhaust Probe and Pump with harness for measuring a vehicle’s mixture from its tailpipe – during chassis dyno testing. This kit combines our AFR module (#430-186) with a reliable vacuum air pump – for extracting hot sample gases at the tailpipe outlet. The pump is powered directly from your shop’s compressed-air supply. The extra-long (bendable) sampling tube avoids fresh-air dilution and sensor-damaging water vapor separation. Your O2 sensors stay accurate and cleaner longer – without constant filter-jar maintenance hassles. The adjustable retention hardware adapts the probe and pump to almost any vehicle’s tailpipe configuration. A remote mount Pulse Dampening Pump Hose kit (#430-189) should also be ordered for most bikes and single-cylinder exhausts. (Requires an available 0-5 volt channel and DYNO-MAX software.)
