Method of testing a gas injector valve and a system for exercising the method

摘要

Method of testing a gas injector valve for a combustion engine. The valve is placed in a holder (1) with a first chamber (2) and a second chamber (3), the valve spraying nozzle (11) being placed in the first chamber (2), after which the valve in a closed condition is influenced by a test gas under pressure to control whether the valve seat and the valve gaskets (13a, 13b) are leak proof. This method makes it possible to indicate the position of a leak if any.

1. A method of testing a gas injection valve for a combustion engine, by which method the valve is placed in a holder (1) having a first chamber (2) and a second chamber (3), the valve spraying nozzle (11) of the valve being placed in the first chamber (2) and the valve in closed condition being influenced by a non-burnable test gas under pressure to check whether the valve seat and the valve gaskets (13a, 13b) are close, whereby the gas which during the supply of gas escapes at the valve seat, is detected separately eventually through a gas discharge tube (20a), which from the first chamber (2) is connected to a separate container (28) with liquid, and the gas which during the supply of gas escapes as a result of leaky valve gaskets (13a, 13b) is detected separately eventually through a gas discharge tube (19) connected to the valve, said gas discharge tube (19) being connected to a second container (29) with liquid.
