Automatic Cold Cranking Simulator (CCS) ASTM D2602 ASTM D5293

Automatic Cold Cranking Simulator 

Measure the apparent viscosity of engine oil using the Cold Start Simulator (CCS) method. Automatic cold cranking simulator can be tested within a temperature range of -10 ℃ to -35 ℃ and is suitable for engine oils with an apparent viscosity between 900mPa. s and 25000mPa. s

 Working principle:

• Temperature control principle: The cold cranking simulator  has a precise temperature control system inside. Cold cranking simulator  can lower the temperature of the test oil sample to a specified low temperature environment, such as -30 ℃ or even lower. Through the collaborative work of refrigeration systems (such as liquid nitrogen refrigeration or compressor refrigeration) and temperature sensors, the test temperature can be accurately controlled to achieve a simulated cold weather state for the oil sample.

• Simulated start-up process:In a low-temperature environment, the instrument simulates the crankshaft rotation when the engine is started by driving it through a motor. When the motor rotates, it drives the rotor in the testing chamber where the test oil sample is located to rotate. This rotor is similar to the engine crankshaft, and the oil sample flows in the gap between the rotor and the stator. The cold cranking simulator  measures the torque required for the motor to start, in order to evaluate the fluidity and pumpability of the oil sample at low temperatures. Because in the actual engine start-up process, oil needs to be quickly pumped to various key components of the engine for lubrication. If the oil flow is poor, it can cause difficulty or even damage to the engine start-up.

 Application area:

• Lubricating oil industry: Cold cranking simulator is an essential tool for the research and quality control of lubricating oil production enterprises. By using a cold start simulator, it is possible to test the performance of different formulations of engine oil at low temperatures, optimize the formulation of lubricating oil, and ensure that it can provide good lubrication and protection for the engine in cold weather conditions.

• Automotive manufacturing and maintenance industry: When choosing engine oil, car manufacturers need to conduct cold start simulator testing to ensure that the selected oil can meet the usage requirements of the car in different regions (especially cold regions). Car repair shops can also use this instrument to test the performance of engine oil and provide reasonable oil change suggestions for car owners.

• Petrochemical product quality supervision department: Used to conduct quality supervision and testing of engine oil sold in the market, ensuring that the products meet relevant standards and quality requirements, and protecting consumer rights and interests.
