Cummins Diesel Cautions

DATE:2019/6/24 14:09:52 HITS:741

1 Note the use of the Cummins Engine
1), the engine start
   To check the cooling liquid level every day for the first time before the start of oil ruler, and the oil-water separator water. The starter starting time can not be more than 30 seconds, consecutive start, an interval of two minutes. Within 15 seconds after the engine is started, to observe the changes in oil pressure. A day after the first start, low-speed warm-up 5 minutes before starting the temperature is below 0 ℃ must do so.
2), the preheating of the engine and an idling
   The engine Starting preheating runtime, should gradually increase the engine speed, and prohibiting the throttle operation of the engine. Engine idling more than 10 minutes is strictly prohibited.
Note: engine idle for a long time, will lead to the combustion chamber temperature drops, causing poor combustion, form carbon deposits obstruction glib orifice and cause the piston rings and valves stalemate.
3), the engine stop
   Before shutdown of the run, the engine must idling 3 to 5 minutes, so that the lubricating oil and cooling fluid to the combustion chamber, the bearing and the friction pair of heat away, especially cold engine supercharger and a turbocharger, is particularly important.
 
2, the use of the Cummins Engine Handling Precautions
1), to avoid the continuous operation of the engine in the case of the cooling liquid is less than 60 ° C or higher than 100 ℃, should find reasons.
2) to prohibit the operation of the engine oil pressure is too low.
3), engine-throttle, maximum torque speed running time must not exceed 30 seconds.
[Note: the minimum oil pressure can not be lower than the specified value in the normal water temperature, engine speed shall not exceed, in any case, the high idle speed (3600 rev / min), the next steep slopes, to prevent engine overspeed, should be used in combination gearbox hanging files and engine or service brakes to control the speed and engine speed. Non-engine with trouble-free operation.
Reminder: The engine in the actual operation of the process, before the failure has early signs to observe the changes in the performance, the sound of the engine, as well as various parameters, if abnormal, inspection or repair should be shut down immediately.
