Description du produit:
The Rolls Royce part number 16136760242 leak diagnosis pump is used to pressurize the evaporative emission (EVAP) system for leak checking. The EVAP system is designed to collect and store fuel vapors from the fuel tank and engine. These vapors are then routed to the intake manifold and burned in the engine.
The leak diagnosis pump closes the EVAP system vent to atmospheric pressure so the system can be pressurized for leak testing. The diaphragm is powered by engine vacuum. It pumps air into the EVAP system to develop a pressure of about 7.5' H20(1/4) psi.
If there is a leak in the EVAP system, the leak diagnosis pump will detect it by the drop in pressure. The pump will also indicate the location of the leak by the sound of the escaping air.
The leak diagnosis pump is a necessary part of the EVAP system and should be replaced if it is faulty. Driving without a leak diagnosis pump can damage the EVAP system and cause fuel vapors to leak into the atmosphere.
Here are some of the symptoms of a bad leak diagnosis pump:
If you notice any of these symptoms, it is important to have your car checked by a qualified mechanic.
