ClearFlame Engine Technologies has matched torque and power of diesel with ethanol

In Massachusetts, ClearFlame Engine Technologies, a start-up dedicated to the development of clean engine technology for the heavy-duty truck, off-highway and industrial markets, announced that it has successfully matched the torque and power of a commercial diesel engine using ethanol in place of diesel fuel, delivering more than 500 horsepower and over 2,500 foot-pounds of torque while eliminating the need for additional aftertreatment such as selective catalytic reduction or diesel particulate filter systems.

ClearFlame achieved these results on a Cummins X15, a 500hp 15L heavy-duty engine using the company’s high-temperature stochiometric combustion process, which leverages higher temperatures to achieve true diesel-style combustion of any decarbonized fuel. Temperatures are achieved by optimizing existing engine thermodynamics and adding insulation on key engine components. The fuel injection system is also engineered to accommodate decarbonized fuels like ethanol.
