ClearFlame Engines is a startup company based in Chicago, IL. The ClearFlame technology enables heavy-duty engine manufacturers to produce engines at lower cost, while simultaneously providing their customers with higher performance and fuel cost savings. We're breaking the paradigm that ties heavy engines to petroleum fuels by 'taking the Diesel out of the Diesel engine'​. Our engine modification enables Diesel engines to run on cleaner burning, sootless fuels in the most efficient manner, unlocking benefits in cost savings, performance, and air quality. We view our technology as being applicable wherever Diesel engines are used - including big markets like heavy duty transportation and distributed power generation, as well as marine, agriculture, construction, mining, and locomotive applications.
