Abstract
A heavy duty vehicle chassis dynamometer driving route, titled "City-Suburban Heavy Vehicle Route" (CSHVR) was developed. Data for designing the CSHVR were collected using a Campbell Scientific 21x. Procedures were developed to reduce statistically the speed and time data into representative speed vs. time cycles. Criteria for producing the speed vs. time cycles included average vehicle speed, standard deviation of vehicle speed and total cruise time. The speed vs. time cycle was converted into a speed vs. distance route with free acceleration ramps. Using this method, the CSHVR was developed. Testing of the CSHVR was completed using the West Virginia University transportable heavy duty vehicle emissions testing laboratory. CSHVR results showed that average emissions values in grams/mile were at levels of 23.3 (NOX), 2563 (CO2), 1.98 (HC), 0.78 (PM) and 6.03 (CO) while driving the CSHVR.
