Title:
TEMPERATURE ADJUSTMENT SYSTEM OF OIL FOR TEST
Document Type and Number:
Japanese Patent JP2017075862
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform engine operation test with high reproducibility of a practical vehicle environment.SOLUTION: A temperature adjustment system includes: a pump 11 configured to feed out oil; a thermometer 15 configured to acquire a temperature of oil passing through the pump 11; a liquid-gas separation unit 12 configured to separate gas and liquid contained in oil fed out from the pump 11; a temperature adjustment unit 13 configured to adjust a temperature of oil in which gas is separated by the liquid-gas separation unit 12; a cylinder part 14 arranged on a downstream side of the temperature adjustment unit 13, and configured to store oil and perform oil supply by driving a cylinder 14a; a transaxle 3 to which oil discharged from the cylinder part 14 and oil with gas and liquid mixed discharged from the liquid-gas separation unit 12 are supplied; and an arithmetic control unit 16. The cylinder part 14 includes a position sensor 14b configured to measure a movement amount of the cylinder 14a in supplying oil. The arithmetic control unit 16 calculates the total volume of oil by using the temperature of oil and the movement amount of the cylinder 14a.SELECTED DRAWING: Figure 1
