Description
Technical field
The utility model is related to a kind of mechanical device, more particularly to a kind of cetane test method machine oil supply system.
Background technology
Cetane number is to represent pyrophorisity index when diesel oil burns in diesel engine, and Cetane number Tai Gaotai is low not
It is good.Cetane number is too low, and vehicle can produce pinking, and cold start is difficult, and oil consumption is increased, is unfavorable for vehicle and normally uses；16
Alkane value is high, and diesel oil has good burning performance, but Cetane number is too high and is also not suitable for, be further continued for after diesel cetane-number is higher than 50
Improve, the shortening to time lag of inflammation acts on little, and the too high diesel oil molecules amount of Cetane number is larger, makes the low temperature stream of diesel oil
Dynamic property, atomization and volatility all effected, can make incomplete combustion, cause engine power to decline, oil consumption is raised and is vented
Over-emitting black exhaust.
Cetane test method machine is used for the Cetane number for measuring diesel oil, and measuring principle is by the stagnant combustion to diesel combustion
Phase, to test diesel oil ignitability, the Cetane number of diesel oil is calculated by the delay period corresponding to different standard specimens.
The oil supply system of existing cetane test method machine, using EFI mode fuel feeding, the data for determining machine testing are not smart enough
Really, data redundancy is poor.
Utility model content
In view of the above-mentioned problems, the utility model purpose is to provide a kind of cetane test method machine oil supply system, to solve
The problem of inaccurate data, poor repeatability are detected in certainly existing production.
To achieve these goals, the technical solution of the utility model is as follows：
Cetane test method machine oil supply system, including high-pressure oil pump, cylinder volume, connecting rod, the high-pressure oil pump pass through
Oil feed line is connected to cylinder volume fuel feeding, one end of the connecting rod with the Oil Switch of the high-pressure oil pump, the movement of connecting rod
The break-make of Oil Switch can be achieved, the connecting rod other end is connected with electromagnet, the control system connection of the electromagnet and measuring machine,
The measuring machine control system is by controlling the flexible drive connecting rod of electromagnet to move, so as to control high-pressure oil pump throttle to open
The break-make of pass.
Cetane test method machine oil supply system of the present utility model, existing EFI side is replaced using high-pressure oil pump fuel feeding
Formula fuel feeding, sets connecting rod on the Oil Switch of high-pressure oil pump, and connecting rod is connected with electromagnet, and measuring machine control system passes through control
Flexible, the drivening rod movement of electromagnet, so as to control the break-make of high-pressure oil pump Oil Switch, makes fuel feeding more safety and stability,
Will not abnormal driving, the data of detection are more accurate, repeatability more preferably.
Brief description of the drawings
Fig. 1 is the utility model cetane test method machine oil supply system structural representation.
Embodiment
In order that technological means of the present utility model and implementation are apparent to, it is further with reference to specific embodiment
Illustrate the utility model.
Referring to Fig. 1, cetane test method machine oil supply system of the present utility model, including high-pressure oil pump 100, cylinder volume
200, connected between high-pressure oil pump 100 and cylinder volume 200 by oil feed line, so that high-pressure oil pump 100 is to cylinder volume 200
Middle fuel feeding, is connected with connecting rod 300 on the Oil Switch 110 of high-pressure oil pump 100, and the achievable throttle that moves left and right of connecting rod 300 is opened
The break-make of pass 110, the other end of connecting rod 300 is connected with electromagnet 400, and electromagnet 400 is connected with the control system of measuring machine；Survey
The control system of machine is determined by controlling the flexible of electromagnet 400, and drivening rod 300 is moved, so as to control the oil of high-pressure oil pump 100
The break-make of door switch 110.
Cetane test method machine oil supply system of the present utility model, is set on the Oil Switch 110 of high-pressure oil pump 100
Connecting rod 300, connecting rod 300 is connected with electromagnet 400, and measuring machine control system is by controlling the flexible of electromagnet 400, drivening rod
300 movements, so as to control the break-make of the Oil Switch 110 of high-pressure oil pump 100, make high-pressure oil pump 100 to the fuel feeding of cylinder volume 200 more
Accurately, the data for determining machine testing are more accurate, repeated more preferable.
Principal character of the present utility model, working method and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply principle of the present utility model, the utility model also has respectively on the premise of the utility model spirit and scope are not departed from
Changes and improvements are planted, these changes and improvements are both fallen within the range of claimed the utility model.
