How does the pressure sensor glow plug work?

How does the pressure sensor glow plug work?

Optimised combustion: the PSG Glow Plug measures the pressure in the combustion chamber with an integrated sensor and reports this to the engine control electronics; Integrated concentric automotive plug. The following pressure curves show the course of a PSG signal and a reference sensor signal in the combustion chamber of a test bench engine.

How do you test a glow plug in an engine?

Testing Glow Plugs in the Engine Grab a multimeter. Set your multimeter to ohms. Find resistance value of your multimeter. Test the voltage of the battery. Locate the glow plugs. Remove the caps or connectors to the glow plugs. Clip the multimeter’s negative lead to a ground point in the engine.

What are the features of a PSG glow plug?

Technical features 1 Optimised combustion: the PSG Glow Plug measures the pressure in the combustion chamber with an integrated sensor and reports this to the engine control electronics; 2 Sensor principle: piezoresistive; 3 Flexible heating rod for pressure transmission; 4 Robust sealing element between body and heating rod;

Where are the ground points for glow plugs?

The main two ground points can be found by following the wire that leads from the negative battery terminal into the engine wall or following the wire that leads from the alternator into the engine wall. These wires are attached to bolts. Attach the negative lead onto one of these bolts for grounding.

What does a PSG glow plug do for an engine?

Optimized combustion: the PSG measures the pressure in the combustion chamber with an integrated sensor and reports this to the engine control electronics PSG is a glow plug with an integrated pressure sensor to improve engine efficiency.

What should I do if my glow plug is not working?

First, disconnect the wires from each of your glow plugs. Then, hook the clip of your 12 volt test light to the battery POSITIVE terminal. Touch the probe of your test light to the terminal of the glow plug itself (NOT the wiring harness!). Any glow plugs that does not light the test light is bad.
