Abstract
The utility model discloses a lubricating system for the fast starting and stopping of a mixed power diesel engine, comprising a mechanical oil pump connected with a main oil passage of the diesel engine, and the mechanical oil pump is provided with a sensor connected with a vehicle management system. The lubricating system is characterized in that the main oil passage of the diesel engine is also communicated with an electronic oil pump connected with the vehicle management system. The utility model ensures that the lubricating system of the engine can be kept to have certain pressure when the engine operates and stops, thereby reducing the abrasion of a fiction pair when the engine is started after parking and improving the reliability of the engine. The utility model can especially and greatly reduce the abrasion of the friction pair when the engine of a mixed power passenger car is frequently started and stopped so as to improve the use performance of the vehicle. The lubricating system has simple structure, convenient control and wide application foreground in the field of the mixed power passenger cars.
Description
Technical field
The utility model relates to a kind of lubrication system of diesel engine, particularly a kind of lubrication system that is applicable to the quick start-stop of mixed power diesel engine.
Background technique
When starting once more behind the engine cut-off, oil leak can not form effectively lubricating, and engine scuffing is bigger.The operation characteristic of hybrid power passenger car is to reduce engine idle and fallback zone (when motor during in idling or the operation of inefficient district, with the motor driving car load, making engine shutdown), thus reduced exhaust, fuel saving consumption.In case when vehicle management system needed motor that power output is provided, motor is necessary can instantaneous starting.The hybrid power passenger car particularly engine cut-off and the number of starts of city bus is various, and the initial start stage wearing and tearing are bigger, has a strong impact on the reliability of motor.
Summary of the invention
The utility model provides a kind of lubrication system that is applicable to the quick start-stop of mixed power diesel engine that can guarantee lubricating oil pressure in each moving element of motor and the Oil passage under outage state for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of lubrication system that is applicable to the quick start-stop of mixed power diesel engine, comprise the mechanical oil pump that links to each other with the diesel engine main oil gallery, described mechanical oil pump is provided with the sensor that links to each other with vehicle management system, and described diesel engine main oil gallery also is communicated with the electronics oil pump that links to each other with described vehicle management system.
Advantage and the good effect that the utlity model has are: keep engine lubrication system to have certain pressure in the time of can and stopping in the motor operation, thereby reduce the friction pair wearing and tearing of motor when stopping startup, improve the reliability of motor.The wearing and tearing of the pair of particularly under the state of hybrid power passenger car motor frequent start-stop, can greatly reducing friction, the usability of raising car load.This system architecture is simple, and control is convenient, has a extensive future in the hybrid power passenger car field.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, vehicle management system, 2, the electronics oil pump, 3, the diesel engine main oil gallery.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of lubrication system that is applicable to the quick start-stop of mixed power diesel engine of the utility model, comprise the mechanical oil pump that links to each other with diesel engine main oil gallery 3, the machinery oil pump is provided with the sensor that links to each other with vehicle management system 1, and described diesel engine main oil gallery 3 also is communicated with the electronics oil pump 2 that links to each other with vehicle management system 1.
Working principle of the present utility model:
Work of the present utility model is controlled by motor vehicle driven by mixed power finished vehicle electronic management system, judge engine operating state by the tach signal of its collection and the data of working state, the finished vehicle electronic management system starts electronics oil pump circuit when engine speed is lower than 350 commentaries on classics or shuts down, the electronics oil pump systems starts, the system start-up of motor rapid starting/stopping, oil pressure control system start the maintenance engine lubrication system and have certain pressure; The finished vehicle electronic management system will be controlled electronics oil pump oil-break when engine speed is changeed greater than 350, and electronics oil pump system is out of service, and mechanical oil pump works simultaneously, keeps engine lubrication system that constant compression force is arranged, and prevents that lubricating oil pressure is too high.
Claims (1)
1. lubrication system that is applicable to the quick start-stop of mixed power diesel engine, comprise the mechanical oil pump that links to each other with the diesel engine main oil gallery, described mechanical oil pump is provided with the sensor that links to each other with vehicle management system, it is characterized in that described diesel engine main oil gallery also is communicated with the electronics oil pump that links to each other with described vehicle management system.
