Abstract
The invention belongs to technology in the filed of an engine. In the past, lubricating oil is not supplied to the engine before the engine starts and moving components of the engine are in low oil content state, thus, the abrasion is large to influence the service life of the engine. The invention relates to a method for supplying the lubricating oil in advance before starting of the engine. A device 1 of the invention enables an adjustable pressure check valve, a pressure accumulation oil cylinder (an energy accumulator), and an electromagnetic valve for controlling the pressure accumulation oil cylinder (the energy accumulator) to supply the lubricating oil to a lubricating system in advance to be connected in series sequentially in the original lubricating system of the engine, and controls the electromagnetic valve by an ignition switch to realize to supply the lubricating oil to the engine in advance before the engine starts. A device 2 of the invention additionally connects an electric driver oil pump in front of a lubricating pump of the original lubricating system of the engine and controls the electric driver oil pump to supply the lubricating oil to the engine in advance by the ignition switch. By the two devices, the low oil content condition of the lubricating oil when the engine starts is improved, the abrasion is reduced and the service life of the engine is prolonged.
Description
One, technical field:
The invention belongs to a technology in the engine art
Two, background technique:
All do not shift to an earlier date supplying lubricating oil at present before the engine start, also do not see the interrelated data report, motor its moving element when starting is in few oil condition, and the wearing and tearing that cause are bigger, influenced the working life of motor.
Three, summary of the invention:
Order of the present invention is method and the device that a kind of supplying lubricating oil in advance before starting of engine will be provided, and starts the preceding motor moving element supplying lubricating oil of giving of prerequisite, and the wearing and tearing of few oil improve its working life when improving engine start.
The solution of the present invention is at the method for supplying lubricating oil in advance before starting of engine and device.But its device 1 is to insert successively by pressure regulation one-way valve, storage compressing cylinder (accumulator), solenoid valve in engine lubrication system and return lubrication system oil pipe passage again, makes oil in the storage compressing cylinder (accumulator) in advance to the lubrication system fuel feeding by the ignition switch control electromagnetic valve.
Its device 2 is outside the former engine lubrication system, installs not the electric driving machine oil pump that links with the motor moving element additional, by a switch control electric driving machine oil pump through one-way valve to former lubrication system fuel feeding.
Four, description of drawings: Fig. 1, scheme 1 oil circuit figure, Fig. 2, scheme 2 oil circuit figure
Wherein: but 1 pressure regulation one-way valve, 2 storage compressing cylinders (accumulator), 3 solenoid valves, 4 former lubrication systems, 5 electric driving machine oil pumps, 6 one-way valves, 7 former oil pump, 8 fuel tanks.
Five, embodiment:
In the scheme 1 on the former lubrication system 4 of motor, but insert successively by pressure regulation one-way valve 1, storage compressing cylinder (accumulator) 2, solenoid valve 3 and the oil pipe passage that returns lubrication system 4 again shift to an earlier date to lubrication system 4 fuel feeding the oil in the storage compressing cylinder (accumulator) 2 by ignition switch control electromagnetic valve 3.
Outside the former lubrication system 4 of motor, install not the electric driving machine oil pump 5 that links with the motor moving element in the scheme 2 again additional, and pass through one-way valve 6 to former lubrication system 4 fuel feeding, control electric driving machine pump start prerequisite forward direction lubrication system supplying lubricating oil by ignition switch.
More than in two schemes, second kind is the simplest, fault is less, preferably adopts.
Claims (2)
1. the method and the device of an engine start prerequisite supplying lubricating oil, it is characterized in that method and device at supplying lubricating oil in advance before starting of engine, its device: the 1st, but insert successively by pressure regulation one-way valve, storage compressing cylinder (accumulator), solenoid valve in the engine lubrication supply system and return oil pipe passage again for lubrication system, make oil in the storage compressing cylinder (accumulator) in advance to the lubrication system fuel feeding by the ignition switch control electromagnetic valve.
Its device 2 is outside engine lubrication system, installs not the electrically driven (operated) oil pump that links with the motor moving element again additional, by ignition switch control electric driving machine oil pump through one-way valve to former lubrication system fuel feeding.
2. the method for claim 1 and device, the input pressure that it is characterized in that one-way valve is adjustable.
