DIESEL ENGINES ARE MAINLY USED FOR FINAL SUPPORTING PRODUCTS, SUCH AS HIGH-POWER HIGH-SPEED DIESEL ENGINES THAT ARE MAINLY USED FOR HEAVY-DUTY VEHICLES, LARGE BUSES, CONSTRUCTION MACHINERY, SHIPS, GENERATOR SETS, ETC. THEREFORE, THE DEVELOPMENT OF THE DIESEL ENGINE INDUSTRY LARGELY DEPENDS ON THE MARKET SITUATION OF RELATED END PRODUCTS. SIX PRECAUTIONS SHOULD BE TAKEN WHEN STARTING A DIESEL ENGINE DURING LOW TEMPERATURES IN WINTER.IN THE FIELD OF AGRICULTURAL DIESEL ENGINES, THE MARKET GROWTH IN DEVELOPING COUNTRIES WILL COMPENSATE FOR THE MARKET DECLINE IN DEVELOPED COUNTRIES. THE RAPID GROWTH OF THE GLOBAL POPULATION AND THE UPGRADING OF OLD EQUIPMENT ALL HAVE A GREAT DEMAND FOR AGRICULTURAL MACHINERY, AND THE GLOBAL AGRICULTURAL DIESEL ENGINE MARKET WILL SHOW HIGH-SPEED GROWTH.LOW WINTER TEMPERATURES CAN CAUSE DIFFICULTIES IN STARTING DIESEL ENGINES. IN THIS CASE, SOME PEOPLE INTENTIONALLY USE INCORRECT METHODS TO QUICKLY START THE DIESEL ENGINE, VIOLATING REGULATIONS AND CAUSING DAMAGE TO THE DIESEL ENGINE. SO WHEN STARTING A DIESEL ENGINE DURING LOW TEMPERATURES IN WINTER, PAY ATTENTION TO THE "SIX PRECAUTIONS".1、 PREVENT HEATING THE FUEL TANK AND BAKING THE OIL PAN WITH OPEN FLAMES. HEATING THE FUEL TANK WITH AN OPEN FLAME NOT ONLY DAMAGES THE PAINT ON THE SURFACE OF THE BODY, BUT ALSO EASILY BURNS OUT THE PLASTIC OIL PIPES, CAUSING OIL LEAKAGE. IT MAY EVEN EXPLODE DUE TO THE RAPID EXPANSION OF GAS INSIDE THE FUEL TANK, RESULTING IN THE DESTRUCTION OF THE BODY AND CASUALTIES; BAKING THE OIL PAN WITH AN OPEN FLAME NOT ONLY AFFECTS THE SERVICE LIFE OF THE ENGINE, BUT ALSO EASILY CAUSES THE OIL TO DETERIORATE AND REDUCES THE LUBRICATION EFFECT.2、 PREVENT NOT ADDING COOLING WATER DURING STARTUP. SOME DRIVERS OFTEN USE THE ABNORMAL STARTING METHOD OF WATERLESS STARTING TO QUICKLY START THE DIESEL ENGINE. ADDING COOLING WATER AFTER THE DIESEL ENGINE IS STARTED WILL CAUSE CRACKS IN THE ENGINE BODY AND CYLINDER HEAD DUE TO SUDDEN CONTACT WITH COLD WATER IN THE WATER TANK THAT HAS RISEN IN TEMPERATURE.3、 PREVENT ADDING ENGINE OIL FROM THE INTAKE PIPE. ADDING ENGINE OIL TO THE INTAKE PIPE CAN CAUSE CARBON BUILDUP ON THE PISTON AND PISTON RINGS, REDUCING THEIR LIFESPAN.4、 PREVENT IGNITION WITH OPEN FLAMES. THE AIR FILTER CANNOT BE REMOVED. INSTEAD, DIP COTTON YARN IN DIESEL AND IGNITE IT TO CREATE A FLAME STARTER, WHICH CAN BE PLACED IN THE INTAKE PIPE FOR COMBUSTION ASSISTANCE. IN THIS WAY, DURING THE START-UP PROCESS, THE DUST LADEN AIR FROM THE OUTSIDE WILL BE DIRECTLY SUCKED INTO THE CYLINDER WITHOUT FILTERING, CAUSING ABNORMAL WEAR OF PARTS SUCH AS PISTONS AND CYLINDERS, AND ALSO CAUSING ROUGH OPERATION OF THE DIESEL ENGINE, DAMAGING THE MACHINE.5、 PREVENT FORCED STARTUP WITHOUT PREHEATING. USING OTHER POWER SOURCES TO FORCIBLY START A DIESEL ENGINE WITHOUT PREHEATING CAN CAUSE DRY OR SEMI DRY FRICTION BETWEEN THE CRANKSHAFT AND THE BEARING, WHICH CAN EASILY LEAD TO THE CRANKSHAFT STICKING TO THE BEARING.6、 PREVENT PREMATURE RELEASE OF WATER OR FAILURE TO RELEASE COOLING WATER. RUN AT IDLE SPEED BEFORE TURNING OFF THE ENGINE. WAIT UNTIL THE COOLING WATER TEMPERATURE DROPS BELOW 60 ℃ AND THE WATER IS NOT HOT TO THE TOUCH BEFORE TURNING OFF THE ENGINE AND DRAINING THE WATER. IF THE COOLING WATER IS DRAINED TOO EARLY, THE BODY WILL SUDDENLY SHRINK AND CRACK WHEN EXPOSED TO COLD AIR AT HIGH TEMPERATURES. WHEN DRAINING WATER, THE REMAINING WATER IN THE BODY SHOULD BE COMPLETELY DRAINED TO PREVENT IT FROM FREEZING AND EXPANDING, CAUSING THE BODY TO CRACK.SO, HOW TO START THE DIESEL ENGINE CORRECTLY DURING LOW TEMPERATURES IN WINTER? ONE IS TO USE LOW POUR POINT "0" DIESEL AS FUEL; THE SECOND IS TO PREHEAT DIESEL AND ENGINE OIL WITH HOT WATER; THE THIRD STEP IS TO ADD HOT WATER AT AROUND 70 ℃ AS COOLING WATER AND PREHEAT IT WHILE ADDING IT; THE FOURTH STEP IS TO PREHEAT THE OIL PAN BOTTOM, FUEL INJECTOR, HIGH-PRESSURE OIL PIPE, AND ENGINE BODY SEPARATELY WITH CHARCOAL OR HOT WATER BEFORE STARTING.
