Exhaust Pulse Pressure Sensor – 6008
It offers a fast and accurate method to diagnose engine problems. Used to verify the mechanical condition of the engine before using a scan tool.
Since 2004 a worldwide use of the so called Pressure Pulse Sensors – PPS in automobile diagnostics started.
In normal operation of internal combustion engines pulse waves of pressure are generated in various systems. All engines produce such waves and their shape is predictable. All engines produce a predictable pattern of these pulses so any change in shape or appearance of asymmetry of these pulses indicates a problem with the engine. PPS detects such faults as burnt valves, bad injectors and other performance problems without major disassembly of the engine. To visualize the waveform of the output signal of PPS, its electrical part is connected to an oscilloscope (motor tester; automotive scope). The screen will show in real-time the work of valves, cylinders and injectors, and by using synchronization to the first cylinder it can be determined by its performance which cylinders has a problem. The auto mechanic can therefore quickly and accurately get an idea of the actual condition of the engine. Pressure Pulse Sensor does not need an additional external power supply and it can be used with most modern digital storage oscilloscopes (motor tester).
This sensor can also be used in the intake manifold to measure intake pressure pulses. Combine this with another sensor in the exhaust and a sync signal and you can get a much clearer picture of the mechanical integrity of the engine.
This sensor comes with an information guide and some sample waveforms. There are no special settings for this tester and can be used with virtually all lab scopes that have a BNC plug in or if necessary you can purchase a BNC to banana plug adapter if that is what your lab scope uses.
Pressure Pulse Sensor we can observe the waveform of:
- Pulsation of exhaust gases in the exhaust;
- Changes in the gas pressure in the inlet manifold;
- Fluctuations in the membrane pressure regulator of the fuel;
- Crankcase gases and other;
