Abstract
The utility model relates to a gasoline-methanol inlet gas heating double fuel engine, which comprises an atomizer, a cylinder body, a cylinder head, a piston, a cylinder liner, an air inlet valve, an air exhaust valve, a connecting rod, a crankshaft, an air inlet and an exhaust port, wherein, two sets of air inlet passages are arranged between the atomizer and a combustion chamber, and an outlet of the atomizer is communicated with the air inlet of the combustion chamber. An exhaust pipe is communicated with the exhaust port of the engine, the exhaust pipe is penetrated through an air inlet pipe, and the air inlet pipe is used for burning methanol. The outlet of the atomizer is also communicated with a connecting pipe and the combustion chamber, the air inlet pipe and the exhaust pipe have separate passages, and the air inlet pipe is used for burning gasoline. A conversion valve is arranged between the two air inlet passages, and the conversion valve can be opened or closed to control the engine to burn methanol or gasoline.
Description
The utility model relates to a kind of both burnings gasoline, again the gasoline of burning methyl alcohol-methyl alcohol air inlet heating type duel fuel engine.
At present, conventional engines done to burn methanol fuel after part is improved, but, since methyl alcohol with the air mixing atomization process in a large number the heat absorption, cause air intake branch and oil nozzle temperature very low, wax in the methyl alcohol is easily in this curing, therefore oil nozzle often takes place stopped up by wax and burn and do not blow out phenomenon only.In addition, in the area of no methanol fuel, methanol vehicle can't be runed.
Consult shown in Figure 1: conventional engines air inlet, exhaust branch pipe structure and working principle: the methanol gas of atomizing enters each firing chamber of motor generation power that burns by atomizer air outlet 2 through air intake branch 1, suction port 4, waste gas after burning is discharged through exhaust branch pipe 5 by exhaust outlet 3, and air intake branch 1 is respectively two independent structures with exhaust branch pipe 5.
The purpose of this utility model is: provide a kind of simple in structure, volume is little, cost is low, energy-conservation consumption, the waste heat that utilizes engine operation to discharge is heated to the methyl alcohol atomization gas of low temperature, thereby avoids oil nozzle to be stopped up by wax and methyl alcohol burns and do not blow out phenomenon only, under the situation of no methanol fuel, by changing valve, the also gasoline of burning gasoline-methyl alcohol air inlet heating type duel fuel engine.
The utility model is achieved by the following technical solution:
A kind of gasoline-methyl alcohol air inlet heating type duel fuel engine, mainly constitute by fuel atomizer, cylinder body, cylinder cap, piston, cylinder sleeve, intake valve, exhaust valve, connecting rod, bent axle, fuel air mouth, waste gas outlet, it is characterized in that, the intake duct of motor has two groups, one group of atomizer air outlet straight through combustion chamber uses during as combustion gasoline; Another group outlet pipe passes from suction tude, outlet pipe and motor air outlet UNICOM, and atomizer air outlet and suction tude connect, suction tude and air inlet of combustion chamber connect, and between two groups of intake ducts, changing valve are set, by the unlatching and the closure of changing valve, control motor combustion methyl alcohol or combustion gasoline.Intake duct reaches more than 25% air outlet flue encirclement rate, and this uses when being combustion methyl alcohol; Close the gasoline intake duct, engines combustible methyl alcohol; Close the methyl alcohol intake duct, engines combustible gasoline.
The utility model has improved the structure of conventional engines air intake-exhaust arm, utilizes the waste heat of engine exhaust that the methyl alcohol atomization gas is heated, and experiment showed, to have significant technique effect:
One, two kinds of fuel of burning methyl alcohol and gasoline.Methyl alcohol belongs to clean fuel, and environmental pollution is very little, and price is lower, but the methyl alcohol supply station is still not general at present, not only flammable methyl alcohol of air inlet heating type duel fuel engine but also flammable gasoline have solved the matter of great urgency under the no methyl alcohol situation, make methanol vehicle not limited by fuel region.
Two, avoided oil nozzle to be stopped up and burnt clean phenomenon by wax.Content of wax composition is higher in the methyl alcohol that China produces at present, and the utility model has played the effect of heating to the methyl alcohol mixed gas, so the wax in the fuel can not solidified, has avoided oil nozzle by the wax blocking phenomenon; Because the methyl alcohol atomization gas has obtained heating, the fogging degree of methanol fuel is improved, and therefore, has solved the unclean problem of burning, has improved the utilization ratio of fuel.
Three, simple in structure, easy to operate.
Four, low cost of manufacture, easy to maintenance.
This device description of drawings:
Fig. 1 is traditional air intake-exhaust manifold configuration figure;
Fig. 2 is an air inlet heating type duel fuel engine air intake-exhaust duct ligation composition plan view;
Fig. 3 is the A-A sectional view of Fig. 2;
Fig. 4 is the B-B sectional view of Fig. 2;
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiments:
Exhaust 5 exports 3 UNICOMs with engine exhaust, and atomizer air outlet 2, intake duct 6, air inlet of combustion chamber 4 be UNICOM successively; Air outlet flue 5 passes from intake duct 6; Atomizer air outlet 2, air vent 1, air inlet of combustion chamber 4 be UNICOM successively, between intake duct 1 and intake duct 6 changing valve 7 is set.During combustion methyl alcohol, changing valve 7 cuts out intake duct 1, and the methyl alcohol atomization gas enters intake duct 6 by atomizer mouth 2, enters engine chamber through suction port 4 and burns, and waste gas after burning enters air outlet flue 5 through relief opening 3 and discharges; The methanol gas of atomizing flows around the air outlet flue 5 of higher temperature, makes the heating of methyl alcohol atomization gas, has dissolved the wax in the methyl alcohol, has increased the methyl alcohol fogging degree; During combustion gasoline, changing valve 7 is with air vent 6 sealings, and then air vent 1 is opened, and gasoline mixture enters intake duct 1 by atomizer mouth 2, enters combustion chambers burn through suction port 4 again.All the other structures are identical with the conventional engines structure, seldom give unnecessary details at this.
The utility model is a kind of with methyl alcohol, and--duel fuel engine of this fuel of----gasoline, very convenient, suitable to the anti-pollution transformation of the existing vehicle of society, its development prospect is very extensive.
