    Abstract

    For decades, most all heavy-duty engine coolants contain nitrites in order to protect against cavitation erosion/corrosion. So much so that many industry specifications require nitrites by name as well as minimum concentration quantities as they have been found to be very effective in minimizing cavitation erosion/corrosion of heavy-duty engine cast iron cylinder liners. However, the use of nitrites has become an issue because it is commonly known that nitrites could produce carcinogens when mixed with amine-type coolants. Legislation in some countries recommend not using it. This paper introduces nitrite-free, organic acid based, long-life coolant technology that gives the desired cavitation protection.
