Cold start performance is an important indicator of vehicle environmental adaptability.
Taking a certain diesel vehicle as an example, this paper takes additional measures of cold start at
?41 ℃ for the whole vehicle, conducts a series of test studies in the low-temperature environment
cabin, finds out the key factors that affect the success of the test, verifies, checks and recants one
by one, and finally achieves this performance index. The whole cold start test process is to first
check the low temperature flow of vehicle battery, starter hardware configuration, as well as oil,
filter, fuel oil, wood filter, coolant and other liquids, and then arrange the test personnel and test
steps, and finally the engine intake preheating, injection rail pressure, oil pressure, starter towed
speed, engine water temperature and other parameters measurement and record. At the same time,
analyze, check, rectify and verify the failure of the first cold start test, as well as the successful
completion of the second cold start test. This ?41 ℃ cold start test provides a good idea and method
for the implementation and rectification of diesel vehicle cold start test.
