Compared with prior art, the pressure charging system of V-type gas engine according to the present utility model has following beneficial to effect
Fruit: for the pressure charging system of the V-type gas engine using the double mixer arrangements of double boosters, charging efficiency is high, starts conducive to raising
The power of machine；And pipeline connection and reasonable arrangement, it ensure that overall performance and reliability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram according to the pressure charging system of the V-type gas engine of the utility model first embodiment.
Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical
Novel protection scope is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1, according to the pressure charging system of the V-type gas engine of the preferred embodiment in the utility model using double pressurizations
The double mixers arrangements of device, specific structure include: the first mixer, preceding booster 1, the second mixer, rear booster and in it is cold
Device 2, wherein combustion gas arrives separately at two mixers, mixes with the air after air filter, forms gaseous mixture, then before respectively enteing
Booster 1 and rear booster.Preceding booster 1 and rear booster are pressure charging system independent, are then aggregated into cold in one
Device 2, gaseous mixture after compression, improve the atmospheric density for being filled with cylinder, ignition system it is good fit under, make more to fire
Material is able to full combustion, improves power, and improve economy.Charge inter cooling is by the cooling of compressed gaseous mixture, into one
Step improves density, increases air inflow, to further increase power, while reducing the temperature of combustion chamber.
The upstream of first mixer is connected with the first mixer connecting tube, and the upstream of the second mixer is connected with the second mixing
Device connecting tube, the first mixer connecting tube and the second mixer connecting tube respectively with two of gas inlet three-way connection after pipeline
Connection, combustion gas arrive separately at two mixers by three-way connection, mix with the air after air filter, form gaseous mixture.
The downstream of first mixer is connect with preceding booster 1, and the downstream of the second mixer is connect with rear booster, preceding pressurization
Device 1 and rear booster are the precision machinery to run at high speed, can not arbitrarily be tampered, and breaking down should send maintenance center to repair.Two
Booster is likewise, only installation direction is different, and a turbine end is preceding, another turbine end is rear.Engine from
Rear and front end air inlet enters booster after mixer and combustion gas mixing.
Preferably, preceding booster 1 and rear booster are assemblied on engine top, and whirlpool end is arranged at whirlpool end, and outlet converges
Facilitate subsequent arrangement silencer to one outlet.
Preferably, the equal length of the first mixer connecting tube and the second mixer connecting tube.If the two deviation is too big, then
It is unbalanced to may cause engine two sides.
Preferably, the caliber of the preceding pipeline of three-way connection is greater than the first mixer connecting tube or the second mixer connecting tube
Twice of caliber, to guarantee airflow smooth.
Intercooler 2 belongs to the water tank intercooler component of gas engine, the compressor of both preceding booster 1 and rear booster
Outlet side is connect with intercooler 2, i.e., it is cold in one that preceding booster 1 and rear booster are that pressure charging system independent is aggregated into
Device 2.The gaseous mixture that supercharger air compressor comes out is not directly entered the air inlet pipe of engine instead of, will be pressurized gaseous mixture with pipe
It is air-cooled but to lead to intercooler progress water-.Herein, compression gaseous mixture further increases its density, is conducive to mention through supercooling
The power of high engine improves performance.
When engine with supercharger 3 works, the exhaust gas from the exhaust pipe of engine enters turbine, and the thermal energy in exhaust gas pressure makes whirlpool
Wheel rotation, and make to rotate with the coaxial compressor of turbine.Gaseous mixture (air+combustion gas) is sucked and is compressed by compressor, is then led to
Piping enters engine air inlet tube, and the exhaust gas for having cooled down and having expanded for leaving turbine guides engine exhaust system by turbine case
And enter atmosphere.
Gaseous mixture after compression, improves the atmospheric density for being filled with cylinder, ignition system it is good fit under, make more
Fuel be able to full combustion, improve power, and improve economy.Charge inter cooling is to cool down compressed gaseous mixture,
Density is further increased, increases air inflow, to further increase power, while reducing the temperature of combustion chamber.
To sum up, the pressure charging system of the V-type gas engine is using the double mixer arrangements of double boosters, and charging efficiency is high, benefit
In the power for improving engine；And pipeline connection and reasonable arrangement, it ensure that overall performance and reliability.
The description of the aforementioned specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be limited to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out
It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the utility model
