Embodiment Construction

[0014] Gas injection valves for internal combustion engines must be regularly controlled since gas leakage can lead to the escape of explosively hazardous gases.

[0015] figure 1 A system for testing gas injection valves according to the present invention is illustrated. The system includes a valve holder 1 etc., to which detection gas, seal oil, and control oil can be supplied. exist figure 2 perspective and Figure 3a and 3b The valve holder 1 and the gas injection valve provided in the valve holder 1 are illustrated in section of . exist Figure 3a The valve holder 1 illustrated in has a first chamber 2 and a second chamber 3 . A valve disposed in the holder includes a body with a continuous opening in the longitudinal direction. A valve spray nozzle 11 is mounted to the lower part of the body by means of a coupling 8 with an incoming collar. The valve spray nozzle 11 has an elongated opening connected to a through hole in the body, in which opening there is a spi...

Abstract

A method for testing a gas injector valve for an internal combustion engine. The valve is arranged in a holder (1) having a first chamber (2) and a second chamber (3), the valve spray nozzle (11) is arranged in said first chamber (2), after which, in the closed state The lower valve is affected by a test gas under pressure to control whether the valve seat and valve gasket (13a, 13b) are leak-proof. This method can indicate the location of a leak, if any.

Description

technical field [0001] The invention relates to a method and a system for testing gas injection valves for internal combustion engines. Background technique [0002] WO 9824014 discloses a system for testing fuel injection valves by means of compressed air. However, such systems are insufficient for testing gas injection valves for internal combustion engines, in which even small leaks are unacceptable and could cause an explosion. [0003] Systems exist for testing gas injection valves for internal combustion engines. However, this system is not satisfactory. Contents of the invention [0004] The object of the present invention is to provide a method for testing gas injection valves which should also be able to detect even the smallest leaks. The method should also be simple. [0005] A method according to the invention of the above type, characterized in that the valve is arranged in a holder having a first chamber and a second chamber, the valve spray nozzle of the...
