Problems solved by technology

[0006] 2. Since the current temperature control mechanism of the cracker will switch frequently when it is at the critical control temperature, the temperature in the cracking chamber will fluctuate
The cracking chamber cannot be stabilized at the optimal cracking temperature required by the catalyst, which reduces the average gas production of the cracker
[0007] 3. The axial dimension of the current technical solution is long, which is not conducive to the layout of the whole vehicle

Embodiment 1

[0039] The invention provides an alcohol-hydrogen engine throttle valve with a double structure, which aims to precisely control the temperature of the gas entering the cracker, and accurately adjust the exhaust volume entering the cracking heating chamber through the throttle valve, so as to control the internal temperature of the cracking chamber the goal of.

[0040] like figure 1 As shown, the present invention provides a kind of alcohol-hydrogen engine throttle valve with double structure, including: motor 1, coupling 2, double throttle base 3, first exhaust valve disc 4, second row Valve disc 5 and throttle shaft 6.

[0041] The motor 1 is fixed on the dual throttle base 3 .

[0042] Motor 1, also called electric motor, commonly known as motor, refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The main function of the motor 1 is to generate driving torque. As a power s...

Embodiment 2

[0053] figure 1 Shown is the schematic diagram of the three-dimensional structure of the alcohol-hydrogen engine throttle with a double structure according to an embodiment of the present invention; the alcohol-hydrogen engine throttle with a double structure is in figure 1 The state in is the first exhaust valve closed state. figure 2 shown as figure 1 A schematic diagram of the first exhaust valve in an open state in the throttle valve of the hydrogen alcohol engine with a dual structure in the illustrated embodiment. image 3 shown as figure 1 The front view of the hydrogen alcohol engine throttle valve with a dual structure in the shown embodiment in the closed state of the first exhaust valve disc; Figure 4 shown as image 3 Rear view of the hydrogen alcohol engine throttle of the illustrated embodiment having a dual configuration. The following combination Figure 1 to Figure 4 The throttle valve of the alcohol-hydrogen engine with a dual structure according to t...

Embodiment 3

[0084] An embodiment of the present invention provides an alcohol-hydrogen engine, including the alcohol-hydrogen engine throttle valve with a double structure described in the first and second embodiments, and also includes a methanol cracker, an engine exhaust pipe and an exhaust bypass. The methanol cracker includes a cracking heating chamber and a cracking chamber, the first disc hole is used to communicate with the engine exhaust pipe and the cracking heating chamber, and the second disc hole is used to communicate with the engine exhaust pipe and the exhaust bypass. The cracking chamber cracks the methanol under the action of the catalyst by absorbing the heat of the cracking heating chamber.

[0085] The throttle valve of the alcohol-hydrogen engine with a double structure is set between the engine exhaust pipe and the pyrolysis heating chamber, the first disc hole corresponds to the air inlet of the pyrolysis heating chamber, and the second disc hole corresponds to the ...

Abstract

The invention discloses an alcohol-hydrogen engine throttle and an alcohol-hydrogen engine with a double-connected structure, which are provided with a motor, a coupling, a double-connected throttle base, a first exhaust valve disc, and a second exhaust valve disc slice and throttle shaft. The invention uses a motor to drive two linked throttle valves to rotate simultaneously. The motor can keep the throttle valve at any angle, so as to precisely control the exhaust gas volume entering the pyrolysis heating chamber. The two throttle valves only need one executive motor to complete accurate and stable temperature control, and the structure is simple. In addition, the present invention provides a dual throttle valve structure, and the two throttle valves are arranged on the same rotating shaft and driven synchronously. The invention can make the other throttle just close when one throttle is opened, so as to achieve the purpose of switching the exhaust passage. The invention has the advantages of stable structure, small vibration and small axial dimension.

Description

technical field [0001] The invention relates to an alcohol-hydrogen engine, in particular to an alcohol-hydrogen engine throttle valve and an alcohol-hydrogen engine with a dual structure. Background technique [0002] The alcohol-hydrogen engine was developed to improve the cold start performance of the methanol engine and improve the economy of engine operation. The alcohol-hydrogen engine is equipped with two sets of fuel systems, one is methanol fuel; the other is methanol cracked gas fuel. The methanol fuel is directly provided by the methanol fuel tank. Methanol cracked gas is provided by a methanol cracker. [0003] Methanol cracker is a kind of cracking methanol into H 2 The gas generating device for mixing gas with CO is a key component in the research and development of alcohol-hydrogen engines. The methanol cracker absorbs the exhaust heat of the engine and cracks methanol into H2 and CO under the action of a catalyst. The hydrogen produced by methanol cracki...
