Abstract: The malfunction of the WP5/7 diesel engine crankshaft
timing gear was studied in a cold test system. The work conditions of
crankshaft timing, combustion, air admission and exhaust were analyzed. The
results showed that the malfunction of the diesel engine crankshaft timing gear
is accurately detected by cooperating the crankshaft timing test, combustion
test and exhaust test.
