Characteristics and treatment of Steyr diesel engine unit fault alarm
- 2019-05-15-

      Diesel engine as a very important mechanical device with high thermal efficiency, high specific power and easy operation The advantage of its operation directly affects the operation of the entire Steyr diesel engine unit. During the operation of the diesel engine, mechanical failure may occur, which may cause damage to the basic components and cause serious mechanical accidents. Usually, before the diesel engine fails, its engine speed, sound, exhaust, water temperature, oil pressure and other aspects will show some abnormal signs, that is, the characteristics of the fault. The operator should quickly make a correct judgment based on the characteristics of the omen, and take decisive measures to avoid accidents. The characteristics and treatment methods of the Steyr diesel engine unit fault alarm are introduced below.

      1. The omen characteristics of the "speeding" failure

      Before the "speeding", the Steyr diesel engine unit generally Blue smoke, fuel burning or unstable speed will occur. Treatment measures: First, close the throttle, stop the oil supply, step on the brake; second, plug the intake pipe to cut off the air intake; third, quickly release the high-pressure fuel pipe to stop the oil supply; fourth, the high-resistance of the vehicle diesel engine Heavy load (braking) stops the engine due to insufficient torsion.

      Remedy: First, close the throttle, stop the oil supply, step on the brake; second, plug the intake pipe, cut off the air intake; third, quickly release the high pressure oil pipe, stop Oil supply; Fourth, the Steyr diesel engine unit can use the high resistance heavy load (brake) to stop the engine due to insufficient torsion.

      2. The harbinger of the failure of the tamping cylinder

      The tamping cylinder is a destructive mechanical damage. In addition to the valve coming off the cylinder, the connecting rod bearing joint causes the tamping cylinder. Most of them are caused by loose connecting rod bolts, loose connecting rod bolts or increased tension clearance. At this point, a "knock" sound can be heard in the crankcase. The knocking sound is getting louder and louder. The connecting rod bolts are broken or broken, and the connecting rod and the bearing cap are thrown to break the machine. Body and related parts.

      Remedy: Shut down and repair and replace new parts in time.

      3. The omen characteristics of the failure of the adhesive tube

      When the Steyr diesel engine unit is seriously deficient in water, the sticking phenomenon often occurs. The engine in front of the viscous cylinder is running weakly. The water temperature gauge shows temperatures above 100 degrees Celsius. Cold water droplets are on the body. There is a "squeaky" voice, white smoke comes out. The water droplets evaporate quickly.

      Remedy: Steyr diesel engine unit idling for a period of time or flames the crankshaft to help cool, so that the water temperature drops to about 40 °C, then slowly add cooling water. Be careful not to add cooling water immediately, otherwise the parts will be deformed or cracked due to a sudden drop in local temperature.
