Скачать или смотреть Diesel engines misfire analysis using USB Autoscope

The CKP test identifies cylinder misfires in diesel engines. To perform test, record the signal from the Crankshaft Position sensor and a signal from a current transducer. The transducer must be installed on one of the electrical wires from one of the injectors. Analyze the recorded data with USB Autoscope software.
Now let’s move on to some concrete examples.
The first example is a Peugeot Boxer performs well at idle. However, during driving conditions, the engine is running very rough with low power.
The second example is an Opel Vivaro displayed a very rough running condition while driving. Additionally, the idle was very unstable until the engine had warmed up.
The third example is a Mercedes Vito engine with too thick sealing washer installed under the injector for cylinder #1. For that reason, the fuel injected in to the combustion chamber did not swirl and mix properly with the air, causing poor combustion.
