FIELD: engine engineering.
SUBSTANCE: invention relates to engine engineering and may be used for fuel injectors' status monitoring during automotive vehicles maintenance. The device of fuel injector spraying quality testing includes plunger pump for fuel supply into a tested injector and pressure valve. The operating lever is installed in pump outlet and connected with pump plunger to perform driving stroke of plunger pump. The device also includes a connecting mechanism for the tested injector connection to pump outlet, and a fuel measuring unit at pump outlet. The above mentioned device is provided with operating lever limit screw (stopper) installed on the housing. The above stopper is implemented adjustable to ensure control of fuel supply by pump by controlling plunger driving stroke against scale indicating pump supply.
EFFECT: fuel supply corresponding to various types of tested injectors.
