Abstract
The utility model relates to an air-intake heating type methyl alcohol engine, which is composed of an atomizer, a cylinder body, a cylinder cap, a piston, a cylinder sleeve, a crankshaft, a connecting rod, an air intake valve, an exhaust valve, a generator, a starting motor and an integral air intake device, wherein, an air intake and an exhaust port of the engine are provided with a new air intake device and a new exhaust device, and an exhaust pipe of the air-intake heating type methyl alcohol engine is penetrated through an air intake pipe. The residual heat of exhaust gas exhausted during the operation of the engine is used for heating low-temperature methyl alcohol atomized gas in the air intake pipe, and thus the clogging of an oil nozzle and the blast due to incomplete combustion of the methyl alcohol engine in operating process are avoided. The utility model has the advantages of simple structure and low cost.
Description
It can methyl alcohol be the methanol engine of fuel that the utility model relates to a kind of.
At present conventional engines is done and to be burnt 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, the consumption of methanol fuel in service is also higher.
Consult shown in Figure 1: conventional engines intake and exhaust manifold configuration and working principle: the methanol gas of atomizing enters motor 6 each firing chamber generation power that burns by atomizer import 2 through air intake branch 7, suction port 4, and waste gas after burning is discharged through exhaust branch pipe 8 by exhaust outlet 3.Air intake branch 7 is respectively two independent structures with exhaust branch pipe 8.
The purpose of this utility model is: provide a kind of waste heat that utilizes engine operation to discharge that the methyl alcohol atomization gas of low temperature is heated, improve the fuel atomization degree, and can avoid oil nozzle to be stopped up by wax, motor that can burning methanol fuel.
The purpose of this utility model is achieved by the following technical solution:
A kind of air inlet heating type methanol engine, mainly be by atomizer, cylinder body, cylinder cap, piston, cylinder sleeve, bent axle, connecting rod, intake valve, exhaust valve, generator, starting motor, consubstantiality formula air inlet system constitutes, it is characterized in that: the suction port of motor, the relief opening jointing is provided with new intake and exhaust device, the suction port UNICOM of the intake duct of this device and motor, air outlet flue and exhaust opening of engine UNICOM, air outlet flue passes from intake duct, separate with interlayer between intake duct and the air outlet flue, air outlet flue is arranged among the intake duct, and intake duct reaches more than 25% the encirclement rate of air outlet flue outer surface.Utilize the waste heat of engine operation combustion gas, the methanol gas that atomizes is heated.The suction port of the new air inlet-outlet pipe after the improvement is identical with the porting of motor with the size of relief opening.
The utility model has improved the structure of conventional engines intake and exhaust arms, utilizes the waste heat of engine exhaust that the methyl alcohol atomization gas is heated, and experiment showed, to compare with existing methanol fuel automobile to have significant technique effect:
One, avoided oil nozzle by the wax blocking phenomenon.Content of wax composition is higher in the methyl alcohol that China produces at present, and the burning methanol engine after existing the improvement oil nozzle often takes place by the wax blocking phenomenon.This practical technique 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.
Two, avoid burning clean and blow out phenomenon.Because the methyl alcohol atomization gas obtained heating, the fogging degree of methanol fuel is improved, and high combustion is clean and blow out phenomenon to have solved fogging degree that conventional engines often occurs, has improved the utilization ratio of fuel.
Three, simple in structure, easy to operate.The utility model just takes off the intake and exhaust arm of regular gasoline motor, changes this device and gets final product, and other is all constant.
Four, low cost of manufacture is keeped in repair more convenient.
Description of drawings:
Fig. 1 is traditional intake and exhaust manifold configuration figure;
Fig. 2 is this device 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:
Consult Fig. 2, Fig. 3, shown in Figure 4, at engine intake 4, relief opening 3 jointings new intake and exhaust device 9 is set, the intake duct 1 of device 9 and suction port 4 UNICOMs of motor, air outlet flue 5 and exhaust opening of engine 3 UNICOMs, air outlet flue 5 passes from intake duct 1, separate with interlayer between intake duct 1 and the air outlet flue 5, air outlet flue 5 is arranged among the intake duct 1.The methyl alcohol atomization gas enters intake duct 1 by atomizer import 2, enters engine chamber through suction port 4 and burns.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.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--gasoline mixture is the methanol engine of fuel, and very convenient, suitable to the anti-pollution transformation of the existing vehicle of society, its development prospect is very extensive.
