Detailed Description
The invention is further illustrated by the following figures and examples, which are not to be construed as limiting the invention.
The embodiment of the invention comprises the following steps: a methanol automobile cold start fuel evaporation device is shown in an attached drawing 1-2 and comprises an evaporator body 8 with 1 cavity structure, wherein an air inlet manifold port 2 and an alcohol spraying port 1 are respectively arranged at the left end and the right end of the evaporator body 8, a heating wire 3 is arranged inside the evaporator body 8, a temperature sensor 6 is further arranged in the evaporator body 8, the temperature sensor 6 and the heating wire 3 are connected with an automatic temperature controller, and the automatic temperature controller is connected with a vehicle-mounted power supply.
The working principle of the invention is as follows: the heating wire 3 is heated under the control of the automatic temperature controller, the sensor 6 is used for monitoring whether the temperature in the evaporator body 8 reaches the preset temperature or not and feeding back to the automatic temperature controller, the automatic temperature controller controls the heating wire 3 to work to keep the temperature in the evaporator body 8 at the constant preset temperature, the methanol injection port 1 starts to inject methanol fuel, the methanol fuel is heated and vaporized to reach the proper cold start temperature under the high-temperature action in the evaporator body 8, the methanol fuel vapor heated to the proper temperature enters the air inlet manifold through the air inlet manifold interface 2 and then reaches the engine to work. The device can effectively improve the cold start performance of the methanol engine.
