Gap location between ring, to allow, the mist of oil of generation can shorten circulation path and reaches lubrication pair with being lost less；
Air intake duct is used for the inflow of extraneous air；
Air inlet branch road one, the combustion chamber for extraneous air to be introduced to engine；
Air inlet branch road two, for extraneous air to be introduced oil duct；
Control valve is set between air intake duct and air inlet branch road one, air inlet branch road two, and being used for controllably will be in air intake duct
Extraneous air is assigned in air inlet branch road one and air inlet branch road two；
Controller is signally attached to oil pressure sensor, liquid level sensor, ultrasonic atomizer and control valve, when oil pressure passes
Sensor monitors that the pressure of lubricating oil in oil duct monitors the liquid of the lubricating oil in fuel tank less than first threshold or liquid level sensor
When position is less than second threshold, controller starts a ultrasonic atomizer and with the first operation power to soaking the lubrication contained in oil storage ring
Oil carries out atomization process, meanwhile, controller control control valve progressively reduces the aperture of air inlet branch road one with the first deceleration, into
The aperture of gas branch two is then correspondingly increased, and to make the flow of the air of introducing engine chamber gradually reduce, and is drawn
The flow for entering the air of oil duct incrementally increases, and the mist of oil in oil duct is blowed secondary as profit to lubrication by the air in air inlet branch road two
Supplemental lubrication when lubricating oil pressure deficiency；
When the pressure of lubricating oil is further reduced to third threshold value or liquid level is further reduced to the 4th threshold value, controller opens
It moves all ultrasonic atomizers and atomization process is carried out to soaking the lubricating oil contained in oil storage ring with the second operation power, to increase mist of oil
Formation speed and production quantity, and control control valve and the aperture of air inlet branch road one progressively reduced until complete with the second deceleration
Contract fully makes the flow of the air of introducing engine chamber be gradually decreased to zero, and the flow of the air of introducing oil duct is gradually
Increase until the air in air intake duct is fully introduced into oil duct, to accelerate the process of engine shutdown；
Second operation power is more than the first operation power, and the second deceleration is more than the first deceleration；
After air inlet branch road one is fully closed, after postponing scheduled duration, controller closes all ultrasonic atomizers.
It is unexpected in lubricating oil pressure deficiency to avoid engine for the operation that engine charge is gradually reduced due to taking
Shut down and bring bad driving experience to driver, while taking the means of supplemental lubrication, engine dead halt it
It is preceding also to be protected well, engine will not be pulled because of lack of lubrication.
