What is a calibrated oil pump? -:Calibration oil pump is used to calibrate the high-pressure oil pump of diesel engine. Generally, the oil pump plunger must be calibrated after it is worn or replaced. Calibration is mainly to adjust the rated oil supply and uniformity of each cylinder, idle oil quantity, idle speed limit, start enrichment, correct enrichment, high speed limit and so on.

What is the school oil pump-:First of all, the oil pump mentioned here refers to the diesel pump of the engine, and the school oil pump is generally maintained and adjusted. Diesel pump is usually used for several years or even a year, and the engine will burn a lot of oil and emit black smoke. At this time, the oil pump needs to be calibrated, for other reasons. Diesel pump is a relatively intelligent pump, so the school is used to represent maintenance.

What is a school pump? -Check the oil supply system of multi-cylinder internal combustion engine with oil pump. Refers to the correction of oil supply time and quantity.

What is an oil pump? When the oil pump injects oil into the cylinder, there must be a stable time, which is called injection timing. If your oil pump injects oil at the wrong time, it will cause abnormal combustion in the cylinder, which will do great harm to the engine, and poor combustion will lead to increased fuel consumption.

How to calibrate the oil pump-:How to calibrate the fuel injection timing: First, the crank rotates the crankshaft, at which time the piston is at the top dead center and the intake and exhaust valves are closed at the same time; That is, the starting point of fuel injection, write down the flywheel reading, and the fuel injection advance angle will be OK. Second, another method: observe the oil return hole of the fuel injection pump and turn the car. When the fuel plunger blocks (just blocks) the oil return hole, write down the flywheel reading, and the injection advance angle will be OK. You need an oscilloscope to observe the waveform of the cam to match your fuel injection pulse width. In the idle state, the simplest method is actually to look at the cam signal top dead center corresponding to your current starting point. This is your fuel injection time. If you want to correct it, it must be that your current signal and cam signal do not have the above corresponding relationship within the fuel injection pulse width range. Just rewrite the injection timing to meet the two points I mentioned above.

What is a school pump? It is to take the oil pump to a professional test bench and test and adjust its data under various working conditions.

What is a diesel pump? -:indicates correction and repair. Oil pump calibration usually means adjusting the oil quantity. The oil quantity of oil pump used for a long time will change and need to be adjusted according to the data. So be sure to go to a regular pump calibration place, such as the service station of the oil pump, because only they can have the data of the oil pump.

Is the nozzle and the oil pump the same thing? -Hello, it's not nozzle adjustment: adjust the opening pressure, injection quantity and atomization state of the fuel injector ... check and adjust the supercharging capacity of the oil pump ... If there is something wrong with the nozzle of the oil pump, it will affect the power and economy of the car; Although the school oil pump and the school oil nozzle are not the same thing, they can be repaired in the same repair shop or company in the market.

What does it mean to calibrate the oil pump? There is white smoke when starting, which may be the wrong ignition time.
