Description

CNG and LPG double fuel distance increasing unit fuel gas supply control gear

Technical field

The utility model relates to double fuel distance increasing unit fuel gas supply control apparatus field, particularly relates to a kind of CNG and LPG double fuel distance increasing unit fuel gas supply control gear.

Background technique

Stroke-increasing electric automobile is a kind of electric vehicle using other energy (as gasoline) to carry out electric energy supply when dead battery capability.Its groundwork feature (theory) is that in most cases (large probability) is operated in electric-only mode, be operated under a few cases (small probability) and increase journey pattern, namely distance increasing unit produces electric energy provides the driving of motor or charges for battery.China academia circle and the Ministry of Science and Technology generally believe that stroke-increasing electric automobile belongs to pure electric automobile field, and do not belong to hybrid vehicle.Relative to other hybrid vehicles, stroke-increasing electric automobile has simple configuration system, the more important thing is more reliable performance and less cost; Relative to pure electric automobile, the continual mileage that stroke-increasing electric automobile is without fear of an attack from the rear and lower cost.From current technological accumulation and inheritance and the market demand, stroke-increasing electric automobile is one of product having industrialization prospect most; Natural gas engine is on bus, use maximum gas engines, and its utilization is not only due to the economical of it and emission performance, the more important thing is increasing of China's natural gas gas station, makes public transport company's aerating convenient.Area northeastward, due to the impact of being transferred natural gas from the west to the east, the construction of natural gas filling station slightly will lag behind middle part and the southern area of China, and what price was relative will be more expensive, so the public transport company of the Northeast seldom uses gas fuel and major part all adopts liquid gas.

Summary of the invention

In order to overcome the above problems, the utility model provides a kind of CNG and LPG double fuel distance increasing unit fuel gas supply control gear, it has installed the supply system of another fuel additional on the basis of original single fuel distance increasing unit, under the prerequisite not affecting power character, adds the economical of distance increasing unit and practicability; Two kinds of fuel all adopt the Closed-loop Control Strategy performed by CNG closed loop final controlling element, LPG closed loop final controlling element simultaneously, add the emission performance of distance increasing unit.

The technical solution of the utility model is: provide a kind of CNG and LPG double fuel distance increasing unit fuel gas supply control gear, it is by CNG gas cylinder group, CNG pressure transducer, CNG reduction valve, CNG closed loop final controlling element, the manual power valve of CNG, LPG tank body, LPG closed loop final controlling element, the manual power valve of LPG, mixer, double fuel ECU and distance increasing unit composition, CNG gas cylinder group is by CNG pressure transducer, CNG reduction valve becomes low pressure gas, low pressure gas is at CNG closed loop final controlling element, enter mixer under the manual power valve of CNG controls and define fuel supply distance increasing unit, LPG tank body is at LPG closed loop final controlling element, enter mixer under the manual power valve of LPG controls and form fuel supply distance increasing unit, double fuel ECU is control CNG reduction valve simultaneously, CNG closed loop final controlling element, the process of LPG closed loop final controlling element.

Compared with prior art, the beneficial effects of the utility model are: can be applied to the automatically controlled range extender system of various double fuel, increase LPG tank body supply system, effectively can solve the problem of the Northeast's difficulty in starting, add the practicability of distance increasing unit; Increase CNG gas cylinder group supply system, the effective power character increasing distance increasing unit; Increase CNG closed loop final controlling element, LPG closed loop final controlling element, limited adds the economical of distance increasing unit and emission performance.
