Book Description
Significant advances have been made in heavy duty diesel engine technology to meet increasingly stringent environmental regulations for emissions. Today's heavy duty diesel engines are being designed with lighter and softer metals, greater turbocharging, increased combustion controls, and new emission reduction equipment. The cooling systems contained in these vehicles are similarly being impacted by smaller designs, new cooling system configurations, and increased usage of lighter, softer metals. Vehicle thermal loads have significantly increased due to increased power densities, higher engine temperatures, and greater metal-coolant fluxes which places greater emphasis on oxidation/thermal stability, and high temperature corrosion protection performance of the coolant. Other operating conditions (coolant flow rates, turbulence, pressure drops, deaeration) are also becoming more severe calling for improved erosion-corrosion protection, cavitation protection, and elastomer, seal, hose compatibility. This paper reviews the changes in heavy duty diesel engine technology and provides information on coolant performance in 2002-4 emission compliant engines. Predictions are also made on future engine technology and next generation engine coolants.

Book Description
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.

Book Description
Annotation Emerging from a November 1991 symposium in Scottsdale, Arizona, 19 papers report on advances in developing, testing, and applying engine cooling fluids for automobiles and heavy duty engines. Among the topics are carboxylic acids as corrosion inhibitors in engine coolant, phosphate-molybdate supplements to heavy duty diesel engines, the toxicity and disposal of engine coolants, and the characterization of used engine coolant by statistical analysis.

Book Description
This paper is a controlled extended service interval (ESI) study of the comparative behaviors of a nitrite/borate/low-silicate, low total dissolved solids (TDS) coolant maintained with delayed-release filters, and an organic acid inhibited coolant technology in heavy-duty engines. It reports both laboratory and fleet test data from 66 trucks, powered with different makes of heavy-duty diesel engines. The engines were cooled with three different types of inhibitors and two different glycol base (ethylene glycol and propylene glycol) coolants for an initial period exceeding two years and 500 000 km (300 000 miles). The data reported include chemical depletion rates, periodic coolant chemical analyses, and engine/cooling system reliability experience. The ongoing test will continue for approximately five years and a 1.6 million km (1 million miles) duration. Thirteen trucks were retained as controls, operating with ASTM D 4985 specification (GM-6038 type) coolant maintained with standard ASTM D 5752 supplemental coolant additive (SCA). Engines produced by Caterpillar, Detroit Diesel Corp., Cummins Engine Co., and Mack Trucks are included in the test mix.

Book Description
In 1995, a universal "fully formulated" antifreeze/coolant specification was published for the first time in The Maintenance Council (TMC) Recommended Practices (RP) 329 and 330. It was the intent of TMC to provide a coolant that could be used in both automotive light-duty engines and heavy-duty diesel engines. This simple, one-step coolant would allow fleet managers to decrease maintenance while complying with OEM warranty requirements. In addition, fleet managers would have only one coolant to inventory. Extensive data have been presented by various authors and are recorded in the literature regarding the application of this type of coolant in heavy-duty diesel engines. Herein are reported the positive results and documentation of the successful extended service interval (ESI) application of this coolant in light-duty automobile engines, complementing the heavy-duty performance database. Vehicles from the "Big Three" American car manufacturers were operated for a distance exceeding 100 000 km (62 000 miles) with excellent experience. This paper reports the test parameters, test methods, test data and concludes that both TMC RP-329 and RP-330 compliant, phosphate-free low-silicate coolants offer ESI performance for light-duty as well as heavy-duty applications.
