Abstract: The present invention relates to leakage detection unit (100) comprise of an upper housing (5), a lower housing (6) accommodating an electromechanical valve (1), a pump assembly (2), a pressure sensor (3) and a bush (4), wherein the pump assembly (2) includes a pump that permits flow of air that, due to which pressure in passage of the pump becomes constant after a time interval and that pressure is considered as reference pressure. The pressure is measured by help of the pressure sensor (3) and in case the measured pressure is not equal or above to the reference pressure than there is leakage in the isolation valve (100), whereas in case the measured pressure is equal or above the reference pressure that there is no leakage or some permissible amount of leakage in the fuel tank within the time interval.

Abstract: The present invention discloses a dual mode fuel tank leakage detector (100), comprising of an electromechanical valve (1) with a canister port, an engine control unit, pump assembly, a sensor (3) and works in pressure condition by comparing a measured pressure with reference pressure; in case there is leakage then the pressure is not upto the reference pressure within time interval. In case of no leakage, the pressure will be equal/above than the reference pressure, the leakage detector (100) works in vacuum condition by comparing a measured leakage with a reference leakage, in case there is a leakage the measured vacuum is not able to reach to the reference vacuum within a time interval and when there is no leakage, the measured vacuum will be equal or above from the reference vacuum and fuel tank leakage detector (100) enables to monitor leakage detection either in vacuum or pressure conditions.
