Cold-Cranking Simulator CCS ASTM D5293

Cold-Cranking Simulator ASTM D5293

Cold Cracking Simulator (CCS) is a professional equipment that complies with ASTM D5293 standard, used to determine the starting performance of engine oil in low-temperature environments. Its core function is to simulate the high shear conditions during engine cold start, evaluate the flowability of the oil within the range of -35 ℃ to -5 ℃ by measuring the apparent viscosity of the oil, and ensure that the engine can still start quickly and provide effective lubrication under extremely cold conditions.

Test Principle:

Shear simulation: Simulate the high shear environment between the piston ring and cylinder wall during engine cold start by rotating the rotor at a certain shear rate in the stator.

Viscosity calculation: Based on the relationship between rotor speed and driving current, combined with calibration oil data, calculate the apparent viscosity of the oil.

Technical Parameters：

Features:

1. Using imported motor drive with high precision;
2. Automatically calculate the results after calibration with standard oil;
3. All testing processes are fully automatically controlled without manual intervention. The machine will automatically stop and heat up after the test is completed;
4. The instrument automatically recommends the refrigeration temperature; the rotary encoder detects the rotation speed;
5. Viscosity measurement range: 1500~25000CP;
6. Editable 10 kinds of standard oil results;
