Abstract
A gas supply device for diesel and natural gas double fuel engine is provided, wherein the upper part of the device is provided with a natural gas inlet which is connected with a natural gas common rail pipe, a valve seat of an electromagnetic valve and a natural gas supply channel which supplies gas for a cylinder of an engine which are communicated with each other, while the lower part is provided with a natural gas channel with one end which is communicated with an inlet pipe of the engine and the other end which is communicated with the inlet channel of the cylinder of the engine. The utility model has the characteristics of simple manufacture and convenient use, the natural gas can be guaranteed to enter into the cylinder directly without changing the structure of any component of the prior diesel engine, and good effect of uniform mixing of the gas of each cylinder is guaranteed.
Description
Technical field
The utility model relates to a kind of natural gas supply device, particularly a kind of diesel/natural gas dual-fuel engine air feeder.
Background technique
At present along with the attention of society to environmental protection, and the improving constantly of people's environmental consciousness, also just strict more to the requirement of motor vehicle exhaust emission, thereby, continually develop the new clean fuel of development in the world for reducing the pollution of vehicle exhaust to air.As rock gas is exactly the fuel of a kind of economy, cleaning, particularly diesel/natural gas dual-fuel engine, and promptly compliance with environmental protection requirements is more suitable for the use of the large-scale bus in city.But, how guaranteeing the supply that can not waste uniformly when diesel engine provides gas fuel, this is to need the problem that solves.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of can be on former diesel engine directly arrangement just can evenly not waste provide the diesel/natural gas dual-fuel engine air feeder of rock gas to diesel engine.
The technological scheme that the utility model adopted is: have the valve seat of placing solenoid valve on the device, one side of device body has the rock gas suction port that joins with the rock gas common rail pipe, this suction port communicates with the solenoid valve valve seat, also have the natural gas supply passage that communicates with suction port and electromagnetism valve opening in the air-breather to the cylinder air feed, and also have an end and communicate the air passageways that the other end communicates with the intake duct of cylinder with the engine air suction tude.
The utility model is owing to adopt said structure, thereby it is simple to have design and manufacture, characteristics easy to use, the structure that need not change any parts of former diesel engine, just can guarantee that natural gas straight taps into into cylinder, and guarantee that the gas mix uniformly effect of each cylinder is good.
Description of drawings
Fig. 1 is the utility model overall structure sectional view.
Embodiment
Provide specific embodiment below in conjunction with accompanying drawing, further specify the utility model and how to realize.
As shown in Figure 1, this air-breather is to have the valve seat 1 of placing solenoid valve on the device body, side at the device body has the rock gas suction port 2 that joins with rock gas common rail pipe 10, this suction port 2 communicates with solenoid valve valve seat 1, also have the natural gas supply passage 3 that communicates with suction port 2 and solenoid valve valve seat 1 in the air-breather body to the cylinder air feed, and also have an end and communicate with engine air suction tude 4, the air passageways 6 that the other end communicates with the intake duct 5 of cylinder, its rock gas suction port 2, solenoid valve valve seat 1 and natural gas supply passage 3 all are arranged at the top of air feeder, air passageways 6 can be arranged at the bottom of air feeder, the air supply channel 3 of rock gas can communicate with air passageways 6, also can be connected to one directly to the rock gas air pipe 7 of rock gas cylinder air feed locating with one voice of communicating with air passageways 6 of natural gas supply passage 3, air pipe 7 joins with natural gas supply passage 3 by flange 9 and lock screw 8.
The cross section of the air inlet passage 6 on the above-mentioned said air feeder is identical with the cross section of engine air inlet tube 4.
