Diesel engine start

Diesel engine start
First, no cooling water or by adding boiling water, start the engine started after the addition of cooling water, make hot cylinder, cylinder head and other important parts caused by a sudden burst or cold deformation; to the cold body suddenly to 100 °C of water, the same cylinder head and the body will be stimulated crack, the water temperature should be reduced to 60 ~ 70 °C then add.
Second, oil is not required when the engine should not start the decompression lever into “work” position after the oil, but should be in place before the start of oil will throttle lever position. Do not operate according to the provisions of the harmful effects are: a waste of fuel; extra diesel will wash the cylinder wall, piston, lubrication between the piston ring and cylinder liner wear and tear aggravated deterioration; the remaining oil into the pan and reduce lubrication oil will dilute the effect; Excessive cylinder diesel in the formation of incomplete combustion of carbon.
Third, start the engine pulling cars viscous oil in the case of cold start the drop-down cars, will increase the wear between the moving parts, thereby reducing the service life of locomotives.
Fourth, bogey is not scheduled for lubricants, fuel in cold weather season, if not change the low viscosity lubricants and fuel, diesel engine it is difficult to start.
Fifth, Note baking pan with the fire and into the trachea at the fire started in order to prevent fire, the application of a slow coal fire at a distance of diesel oil pan baking, while the oil slowly crank shaft, so that uniform heating oil , so that all parts have been lubricated. If the fire in the engine intake manifold at the start, make the material burning ash and debris sucked into the cylinder hard, resulting in intake and exhaust valve closure is accelerated cylinder wear loose.
Sixth, Avoid prolonged use of glow plugs, glow plug pre-heater flame, flame preheater heating elements are electric wire, the power consumption and heat are large, long-term use may be due to the rapid discharge and damage to the battery, but also electric wire can burn out. Therefore, the glow plug used in each successive time should not exceed 1 minute each successive flame preheater to control the use of time. System in 20 seconds or less.
Seventh, added directly to the oil cylinder to cylinder oil added, though sealed pressurized warming may play a role, cooler engine starts easy, but can not burn oil, easy to produce coke, reduced the flexibility of the piston rings, cylinder sealing performance; In addition, cylinder liner wear will be accelerated, resulting in decreased engine power to make it more difficult to start, so the oil can not be added directly to the cylinder.
Eighth, gasoline poured directly into the trachea lower than that of diesel burning gasoline than diesel fuel before combustion. Therefore, gasoline poured directly into the trachea, will make the engine work and have a strong brutal knock phenomenon can also occur in severe engine reverse.
Ninth, on the long straight start diesel engine at low voltage, high current case work, prolonged use may damage the battery. The continuous period of not more than 5 seconds; a start none, should be re-started every 15 seconds.
Tenth, just start on high speed diesel engine has just started, the oil temperature is low, poor mobility, high-speed operation immediately, could easily lead to lack of lubrication of all moving parts and rapid wear, serious will happen Burnt axle.
