ASTM D7583-16 Standard Test Method for Cavitation Testing of John Deere Coolant

The standard “ASTM D7583-16 Standard test method for John Deere coolant cavitation testing” developed by the American Society for Testing and Materials (ASTM) describes a heavy-duty diesel engine to evaluate coolant protection with respect to cylinder liner pitting caused by cavitation.

For the purposes of this standard, the following terms and definitions apply:

• Blank reference coolant refers to a reference coolant whose identity is unknown to the test facility.
• Blow-through, in internal combustion engines, refers to the combustion products and unburned mixture of air and fuel that enter the crankcase.
• Calibration refers to determining the indication or output of a measuring device relative to a standard.
• Heavy duty refers to average speed, characterized by average speed, power output, and internal temperatures close to potential maximum.
• Heavy-duty engine, in internal combustion engines, refers to an engine that is designed to allow it to operate continuously at or near its peak output.
• Non-reference coolant refers to any coolant other than the reference coolant, such as a research formulation, commercial coolant, or candidate coolant.
• Non-standard testing refers to a test that is not conducted in accordance with the requirements in the standard test method, such as running on an uncalibrated test stand or using different test equipment, applying different equipment installation procedures, or using modified operating conditions.
• Reference coolant refers to a coolant with known performance characteristics that is used as a basis for comparison.
• Test coolant refers to any coolant that is subjected to evaluation in a specific procedure.
• Abrasion refers to the loss of material from a surface or the repositioning of material on the surface. Abrasion usually occurs between two surfaces moving relative to each other and is the result of mechanical or chemical action or a combination of mechanical and chemical actions.

This test engine is a John Deere 10,1 L displacement, turbocharged and intercooled, in-line six-cylinder heavy-duty diesel engine. The engine has an overhead valve configuration. It has mechanical control of fuel metering and fuel injection timing. The test operation includes a 19-minute engine run-in, a 20-hour coolant run-in, and a 230-hour run-in in five cyclic steps. Before each test, the engine is cleaned and assembled with new cylinder liners and gaskets. The test stand is equipped with appropriate instrumentation to control engine speed, fuel flow, and other operating parameters. Coolant performance is characterized by determining the total liner pit area.

This test method was developed to evaluate the ability of a heavy-duty diesel engine coolant to protect against damage from a phenomenon known as cylinder liner cavitation corrosion. This test method can be used for acceptance of an engine coolant specification when all details of this test method are consistent. The engine used in this test method is a production original equipment manufacturer diesel engine whose design has been modified to consistently produce operating conditions that accelerate damage from cylinder liner cavitation. This factor, along with accelerated operating conditions, should be considered when extrapolating test results.
