Evans Cooling Systems, Inc. reports that recent testing results by the Department of Sanitation in New York City (DSNY) and Emisstar LLC, a nationally recognized emissions testing firm, showed fuel-economy improvement while lowering exhaust emissions using Evans waterless heavy-duty engine coolant. The chassis dynamometer test program was performed on a Mack diesel refuse collection truck with an MP7 engine, owned and operated by the DSNY. Two computer-controlled test configurations were selected for the subject vehicle to produce a statistically valid comparison of fuel economy and emissions performance data. The results were fuel-economy improvements of 4.4 and 6.1%, respectively, and a reduction in CO2 emissions of 4.3 and 5.6%, respectively.
