According to the time-type electronically-controlled VE pump, the working voltage is boosted to 50-60V directly only through a control system of the ECU, boosting circuits are not required to be added, a set of boosting circuits can be omitted for the control system, the production cost is reduced substantially, and the reliability of the circuit control system is improved.
Description
Technical field
The utility model relates to diesel fuel system energy-saving and emission-reduction field, relates in particular to the automatically controlled VE pump of a kind of time formula.
Background technique
Last year, (2011) China diesel engine output reached nearly 2,000,000, but most diesel engines that actual entrucking is used all only rest on Europe II emission level (having the considerable part diesel engine also not reach Europe II emission level), bring for the energy waste of China and environmental pollution and seriously influence, this mainly is because backward in technique the causing of oil pump nozzle that diesel fuel system now uses.
Be close on during 2,000,000 diesel engine produces in China, what 80 percent oil-fired system was used all is mechanical oil pump nozzle, the fuel feeding inaccuracy, and the fuel feeding injection pressure is low, causes fuel injection quantity too much, and it is insufficient to burn.Be difficult to reach diesel engine Europe III and the above emission request of Europe III.
Automatical control system will be greatly developed, and common rail system is wherein arranged, electronically controlled unit pump, automatically controlled VE pump etc.Wherein, the automatically controlled VE pump of time formula, only the ECU-V5 of Japan electric coating company production is the most representative.
The automatically controlled VE pump of time formula (ECU-V5), be in the diesel engine for automobile oil-fired system developed since 2000 of Japan electric coating company, it is one of state-of-the-art a Electrocontrolled high-pressure oil pump, it is by the vehicle-mounted ECU control system, the diesel engine real-time working condition is monitored, at any time the delta data of diesel engine after handling, ECU is sent instruction to oil pump, after the core component of oil pump-the high speed injection valve is received instruction, the control oil pump sprays high pressure fuel timely accurately to diesel engine, thereby saved fuel oil effectively, reduced emission of harmful substances, can reach the emission request of diesel engine Europe III easily, if diesel engine adds after-treatment device the potentiality that reach Europe IV emission request be arranged equally.
The automatically controlled VE pump of time formula (ECU-V5) must make the operating voltage of injection valve rise to the 130-150 volt, just can make the injection valve proper functioning.But 12-24 can only be provided on the automobile operating voltage of volt, so, in former ECU circuit, increased by one group of boost pressure circuit.This organizes boost pressure circuit, at present domesticly exists very big difficulty designing and producing, and also makes The whole control system complicated, is difficult to also determine reliability in the short time that making and producing has all increased very big cost.
The model utility content
At above-mentioned defective and the problem of prior art, the utility model purpose provides need not increase the automatically controlled VE pump of a kind of time formula that boost pressure circuit, control system are simple, control is reliable and with low cost.
In order to achieve the above object, the utility model provides following technological scheme:
The automatically controlled VE pump of a kind of time formula comprises:
