Tank for checking the tightness of the diesel fuel system
To do this, combine the fuel line from the fuel tank, which removes excess fuel, seal it with a plug, then disconnect the supply fuel line from the tank and attach a hose to it (1) tank (4). Fuel from a tank filled to 4/5 of its volume, controlled by a fuel gauge tube (2), is supplied to the system at a pressure of 0.3 MPa, which is created by the air pump in the tank (3). The appearance of air and fuel bubbles at the joints indicates their leakage.
Checking the tightness of the intake air path of the engine
Loss of tightness of seals and air ducts leads to the ingress of abrasive (dust) into the engine cylinders, which causes increased wear of the cylinder-piston group and premature engine failure. Places of air leakage when the engine is running at maximum speed are detected by an indicator.
Indicator for checking the tightness of the intake air path
To do this, unscrew the screw (2) to the bottom edge of the hole (1), then take the indicator with the eye towards you with your left hand, and with your right hand, taking the rubber tube with a plug and a tip (3), attach the tip to the places of a possible violation of the tightness of the air path. If the liquid level starts to drop, then a gap has been detected. It is necessary to check all possible places of leakage, mark and eliminate them.
After finishing work, tighten the screw until it stops (2) and put the indicator in the pencil case. The fluid used is antifreeze, diesel fuel or kerosene.
