The causes of diesel engine speed a lot, but the basic is divided into two categories: one is the fuel supply; The second is to burn oil. Two coasters are characterized by overdrive diesel engine, the manifestation but there are differences. Diesel super for cause coasters, exhaust smoke, generally can be used to cut off the fuel supply method to stop; Blue smoke coming oil caused by diesel engine speed, exhaust pipe, only to cut off the oil supply can't effectively stop at this moment, must cut off air supply and rapid depressurisation to stop at the same time.
       Diesel engine "ride" troubleshooting methods

       When there was a "flying car" diesel engine, should be calm, resolute to take effective measures to make it stop, don't be panic.

       Chocked up with fast forcibly remove the air filter, intake pipe, such as air filter to remove, can use clothes or towels tightly cover the air inlet of the air cleaner, make the air could not enter the cylinder in diesel engine flameout, this is the most effective way to stop flying cars.

       Heavy vehicle, it can increase diesel engine load and make the engine stops. Unscrew the high pressure hose connector nut, quickly cut off the supply of diesel. If temporary can't find a wrench, high-pressure tubing will also be smashed, make the engine stops.

       Just "ride" decompression can be handle to stress position, make the engine stops. If the speed of the diesel engine is very high, you can't use this method.

       To stop the "speed", the first cut off the supply of diesel, quickly loosen high-pressure hose connector nut, such as "speed" to immediately stop, then diesel engine "speed" is caused due to excessive supply of diesel. At this moment, can check arm pump plunger oil mediation from sliding out from the speed control lever fork handle or pump plunger and speed regulating lever is stuck in the largest oil position. If the "speed" in just after the replacement oil pump plunger matching parts, should check whether oil pump plunger oil mediation arm embedded control lever fork handle, should also pay attention to the plunger axis to the oil return hole for processing problems and did not drill through. For the lever of the gear oil pump, the assembly, should check the oil quantity adjusting gear and gear lever assembly mark for accurate.

        Special stress is that diesel engine speed occurs, absolutely forbidden to reduce or remove the load of diesel engine, so as not to cause a dramatic increase in speed. Secure parking, speed causes should be analyzed in a timely manner and troubleshooting, to prevent happen again coasters phenomenon. If when driving speed phenomenon in a diesel engine, should also be stepped on the brake to suppress fire engine, but it is strictly prohibited on the clutch pedal.
