THERE ARE MANY REASONS FOR THE SPEED OF DIESEL ENGINES, BUT THEY CAN BE BASICALLY DIVIDED INTO TWO CATEGORIES: ONE IS FUEL SUPPLY; THE SECOND ONE IS BURNING OIL. THE CHARACTERISTIC OF THE TWO COASTERS IS THE HIGH-SPEED DIESEL ENGINE, BUT THERE ARE ALSO DIFFERENCES IN PERFORMANCE. THE SUPER EFFECT OF DIESEL ON COASTERS AND SMOKE EXHAUST CAN GENERALLY BE USED TO CUT OFF FUEL SUPPLY METHODS; THE DIESEL ENGINE SPEED AND EXHAUST PIPE CAUSED BY BLUE SMOKE OIL CANNOT BE STOPPED AT THIS MOMENT UNLESS THE OIL SUPPLY IS EFFECTIVELY CUT OFF. THE AIR SUPPLY AND RAPID PRESSURE REDUCTION MUST BE STOPPED SIMULTANEOUSLY.DIAGNOSTIC METHODS FOR DIESEL ENGINE FAULTSWHEN THERE IS A "FLYING CAR" DIESEL ENGINE, ONE SHOULD REMAIN CALM, TAKE DECISIVE AND EFFECTIVE MEASURES TO STOP IT, AND NOT PANIC.FILLED WITH A QUICK AND FORCED REMOVAL OF THE AIR FILTER, THE INTAKE PIPE, IF THE AIR FILTER IS REMOVED, CAN BE TIGHTLY COVERED WITH CLOTHES OR TOWELS TO PREVENT AIR FROM ENTERING THE CYLINDER. DIESEL ENGINE SHUTDOWN IS THE MOST EFFECTIVE WAY TO STOP THE FLYING CAR.HEAVY VEHICLES CAN INCREASE THE LOAD ON THE DIESEL ENGINE AND STOP THE ENGINE. UNSCREW THE NUT OF THE HIGH-PRESSURE HOSE CONNECTOR AND QUICKLY CUT OFF THE SUPPLY OF DIESEL. IF A WRENCH CANNOT BE FOUND TEMPORARILY, THE HIGH-PRESSURE OIL PIPE WILL ALSO BREAK, CAUSING THE ENGINE TO STOP.RIDING "DECOMPRESSION CAN HANDLE THE POSITION OF PRESSURE AND STOP THE ENGINE. IF THE SPEED OF THE DIESEL ENGINE IS VERY HIGH, YOU CANNOT USE THIS METHOD.STOP THE 'SPEED', THE FIRST CUT OFF DIESEL SUPPLY QUICKLY RELAXES THE NUT OF THE HIGH-PRESSURE HOSE JOINT, AND THE 'SPEED' IMMEDIATELY STOPS. THEN THE 'SPEED' OF THE DIESEL ENGINE IS CAUSED BY EXCESSIVE DIESEL SUPPLY. AT THIS MOMENT, IT IS POSSIBLE TO CHECK WHETHER THE OIL INTERMEDIARY IN THE ARM PUMP PLUNGER IS HANDLING THE SLIDING SPEED CONTROL ROD FORK OR IF THE PUMP PLUNGER AND SPEED CONTROL LEVER ARE TRAPPED IN THE ******* OIL POSITION. IF THE "SPEED" IS CHANGED AFTER REPLACING THE OIL PUMP PLUNGER COUPLING, IT SHOULD BE CHECKED WHETHER THE INTERMEDIATE ARM EMBEDDED CONTROL ROD FORK HANDLE IN THE OIL PUMP PLUNGER IS CORRECT, AND ATTENTION SHOULD ALSO BE PAID TO THE MACHINING PROBLEM OF THE PLUNGER SHAFT RETURN HOLE, WHICH HAS NOT BEEN PENETRATED. THE GEAR OIL PUMP OF THE ROD SHOULD BE ASSEMBLED, AND THE OIL VOLUME SHOULD BE CHECKED TO ADJUST THE GEAR AND GEAR ROD ASSEMBLY MARKINGS ACCURATELY.IT IS PARTICULARLY EMPHASIZED THAT IT IS ABSOLUTELY FORBIDDEN TO REDUCE OR ELIMINATE THE LOAD OF THE DIESEL ENGINE WHEN THE ENGINE SPEED IS HIGH, SO AS NOT TO CAUSE A SIGNIFICANT INCREASE IN SPEED. SAFE PARKING REQUIRES TIMELY ANALYSIS AND TROUBLESHOOTING OF SPEED ISSUES TO PREVENT THE RECURRENCE OF SPEEDING INCIDENTS. IF THERE IS A PHENOMENON OF SPEED WHEN DRIVING A DIESEL ENGINE, THE BRAKE SHOULD ALSO BE APPLIED TO SUPPRESS THE FIRE TRUCK, BUT IT IS STRICTLY PROHIBITED TO USE THE CLUTCH PEDAL.
