The diesel engine has a more comprehensive understanding of the diesel engine's purchase time, use and sales reasons, repair status, and which major parts have been replaced, and what problems are in use.
Second, look at the first is to see whether the model belongs to the phase-out model, and then look at the new and old degree of the diesel engine from the outside, and finally check whether the parts are complete, with or without damage.
Three tests are test machines. The specific steps are as follows:
1. Shake the crankshaft to make the fuel supply for the oil supply pump, such as the injection nozzle emitting a crisp injection sound, indicating that the performance of the plunger and the injector is still good; if the gear chamber has no abnormal sound, it indicates that the gear wear is not serious.
2. Shake the flywheel up and down, if there is no noise, no obvious shaking, indicating that the crankshaft main journal and the bearing shell is not large; turning the flywheel, if there is no "click" sound, indicating crankshaft connecting rod between the journal and connecting rod wear Nothing serious.
3. Depressurize the cylinder and crank the crankshaft. When the decompression is removed, if the repulsion force of the piston is large, the flywheel rotates quickly, indicating that the cylinder sleeve, the piston, and the piston ring have little wear. At this time, the oil pressure gauge should read no less than 1 or the oil pressure indicates that the red buoy can rise quickly. Hand pressure buoys should be laborious.
4. It is relatively easy to start the diesel engine, the exhaust is colorless or light gray, the rotation speed is stable, and there is no noise, indicating that the diesel engine is in good technical condition.
They seem simple, but Breathe Right Nasal Strips have unique engineering that make them an effective tool for managing nighttime congestion and improving sleep.
Nasal Strips are made of flexible, spring-like bands that fit right above the flare of the nostrils. The underside is adhesive so that once positioned on the nose, they stay there. As the bands attempt to straighten back to their original shape, they lift the sides of the nose and open the nasal passages.
This lifting action helps open inflamed sinus passages and makes it easier to breath. Nose strips provide relief for congestion due to colds, allergies, or a deviated septum and reduce snoring caused by nighttime nasal congestion.
