In low temperature weather, when the outside air temperature drops below -10°C, it is difficult to start the diesel engine cold; when the temperature drops to -40°C
In the following cases, if some low temperature start measures are not taken, the diesel engine will not start at all. Simply put together a few specific methods to start the diesel engine at low temperature:
(1) Hot water pre-warming method
This method is suitable for units that use softened hot water as the cooling liquid, and it is more convenient to soften the hot water. The specific method is: first add 40~5 to the cooling system
0°warm water (to prevent the water radiator core tube and cylinder head from bursting and cracking due to sudden boiling of water), and then continue to heat the water (let the water flow out of the cylinder) to gradually increase the water temperature
Preheat. When the temperature of the outflowing water is high, turn off the water drain switch.
(2) Steam preheating method
That is, let the steam enter the cooling system from the downpipe of the water radiator through the pipeline, or directly enter the diesel engine cooling water jacket, and use the steam to preheat the diesel engine cylinder block.
This method is suitable for the use of softened water as the coolant.
(3) Adopt disposal forced circulation fuel heater
The method is to use random diesel oil to pump out the coolant in the diesel engine cooling system through the water pump attached to the fuel heater, and heat it by the heater radiation.
After recirculation to the diesel engine cylinder, the temperature of the cylinder, piston, piston ring and other friction pairs will increase accordingly. In this way, the diesel engine cylinder block
The temperature is heated to about 40 ~ 50°C. The viscosity of the diesel engine oil is reduced after heating, and the lubrication conditions of the diesel engine are improved.
(4) Install a spiral resistance heater in the intake pipe
This device is powered by a battery. Before starting, turn on the power supply for 10 ~ 30S to heat the spiral resistor to heat the air entering the cylinder and improve the diesel engine.
The temperature of the gas in the cylinder at the end of compression.
(5) Scald the intake manifold with hot water, that is, after scalding the intake manifold with hot water, the air entering the cylinder is preheated to increase the compressed air at the end of compression.
The temperature is conducive to the combustion of diesel fuel.
(6) Install spiral resistors on the oil pan
The resistor can heat the oil in the oil pan, reduce the viscosity of the oil, and reduce the starting resistance. When applying this method, the heating time should be controlled to avoid
The heating time is too long and the oil temperature is too high, which will cause the oil to deteriorate and deteriorate.
(7) Start with flame preheating device
The flame preheating device is composed of an electronic controller, a solenoid valve, a temperature sensor, a flame glow plug (installed in the intake pipe), a fuel pipe and a wire. Should
The low working temperature of the device is -40°. Its working process is: switch on the flame glow plug before starting, and after ten seconds, the flame glow plug is heated to 900°C (the temperature
The temperature is enough to ignite the diesel.) The starter is turned on, the solenoid valve automatically opens the oil circuit, the fuel pump pumps out the diesel, and supplies fuel to the flame glow plug through the fuel pipe through the solenoid valve.
Start flame preheating.
(8) Use low temperature starting fluid to assist starting
This method is to inject a fixed proportion of low-temperature starting fluid into the intake manifold of the diesel engine before starting. The ignition point of ether in the low temperature starting fluid is low, at 3.25MP
a. The ignition point of ether under pressure is only about 57°C, so the diesel engine does not need to meet the requirement of low starting speed to ignite and start. Practice has proved that using low temperature
The starter fluid can ensure that the diesel engine starts quickly when the temperature is -45°C.
