FIELD: engines.
SUBSTANCE: invention can be used in internal combustion engine control system. Methods and system for creating sufficient negative pressure in fuel tank for detection of leaks. While pressure in fuel tank 20 is in its mechanical limits, fuel vapors flushed from tank 22 into engine 10 with open isolating valve 110 to create required level of negative pressure in fuel tank 20.
EFFECT: after that, fuel tank is isolated by closing isolating valve 110, and detection of leaks is performed simultaneously with blowing.
