Heavy Duty Diesel Engine Coolants: Technology Update


A summary of current heavy duty engine coolant technology is provided which includes a description of heavy duty engines and applications, current problems and concerns which face the industry, industry standard specifications and test methods which are under development to address the concerns, and future directions for the technology. The special needs of heavy duty engines dictate that engine coolant formulations be developed and made available that are tailored to these engines. Efforts to improve fuel economy and durability while reducing emissions and noise will have an important impact on the application of engine coolant technology to heavy duty diesel engines in the future.
