Diesel injection angle is a very important point that affects all engine characteristics. With its improper installation, detonation may occur and engine cooling radiator and others may break.
Diesel injection angle is a very important point that affects all engine characteristics. With its improper installation, detonation may occur and engine cooling radiator and others may break.
After replacing the timing belt or other engine repair, when you need to set the injection angle again, but it was not possible to find the tags, this method will come in handy. When turning the crankshaft in the direction of rotation, fuel injection will occur from the nozzles. But how to determine this moment if the nozzles are in the engine?
It is possible if you disconnect a high pressure pipe from the nozzle of the first cylinder. The fuel from the pump enters the tube with the nozzle removed slowly, growing in level. If you put on a transparent hose on it, it is easy to track the moment of the maximum level of level. This will correspond to the right moment. Naturally, the moment of injection in the diesel engine occurs with a slight lead, about five degrees before the VMT. For a smooth fuel lifting in the tube, the crankshaft must be rotated slowly, putting the head on the bolt of attaching the pulley in its end. Necessarily in the direction of engine operation.
More accurately, according to the receipt and sound of the engine, the angle is set directly by turning the pump in the mount. If the distribution type pump, like almost all modern cars, you can turn it on a small angle right on the engine operating. The sound of work should not be too tough.
The most accurate adjustment of the angle is made using a strobe, per hundred.
