Problems solved by technology

Due to the large working space, it is impossible to ensure sufficient contact between methanol and catalyst, methanol and exhaust gas, so its working efficiency and speed are relatively low
Moreover, by figure 1 It can be seen that the size of this solution is relatively large, and it is inconvenient to use due to space and weight constraints in the fields of vehicle and airborne

Embodiment Construction

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0037] Such as Figure 2 to Figure 5 As shown, the present invention provides a vehicle-mounted methanol online reforming system using a baffle separation mechanism, including an ECU 13, a methanol tank 14, an engine 15, a reforming device 16, a hydrogen-rich mixed gas valve 17, and a waste gas valve for scavenging 18. High-temperature exhaust valve 19, exhaust valve 20 for supplementing air, methanol flow valve 21, methanol injection flow control valve 22, methanol injector 23 and hydrogen-rich mixture injector 24, engine 15 is provided with intake pipe...

Abstract

The invention discloses a vehicular methanol online reforming system adopting a baffling separation mechanism, wherein an engine is provided with an intake pipe and a vent pipe; a reforming device comprises a reformer, an evaporation section and a baffling separation section; a hydrogen-rich mixed gas valve is connected with a reforming fuel gas outlet and a hydrogen-rich mixed gas ejector througha pipeline; a high-temperature tail gas valve is connected with an evaporation section entrance and the vent pipe through a pipeline; a methanol flow valve is connected with a methanol evaporation pipe entrance and a methanol box through a pipeline; an exit of a waste gas valve for scavenging is connected with a tail gas inlet for scavenging through a pipeline; an entrance of the waste gas valvefor scavenging is communicated with the vent pipe; an ECU is electrically connected with the hydrogen-rich mixed gas valve, the waste gas valve for scavenging, the high-temperature tail gas valve, a tail gas valve for gas supplement, the methanol flow valve and a methanol ejection flow control valve respectively. The vehicular methanol online reforming system adopting a baffling separation mechanism disclosed by the invention achieves aims of realizing vehicular methanol online reforming and splitting methanol fuel into hydrogen-rich combustible gas for a vehicular engine by use of the heat ofhigh-temperature tail gas of the engine and improving the combustion and emission performance of the engine.

Description

technical field [0001] The invention belongs to the technical field of waste heat utilization of automobile exhaust, and in particular relates to a vehicle-mounted methanol online reforming system and a control method using a baffle separation mechanism. Background technique [0002] Compared with traditional fossil fuels such as gasoline, diesel, and natural gas, hydrogen burns cleanly and has no emissions of particles, hydrocarbons, and carbon monoxide; if lean combustion technology is used, hydrogen combustion can further achieve zero emissions. Therefore, hydrogen has great potential to replace traditional fossil fuels and become the main fuel for vehicle engines. [0003] However, hydrogen is in a gaseous state at normal temperature and pressure, so it is not easy to transport and store. When using it, it needs to be compressed into high-pressure and high-density compressed hydrogen and stored in a high-pressure container; at the same time, its molecular weight is small...
