A device for preventing water from entering an electronically controlled voltage regulator

Abstract

The invention discloses a device for preventing water from entering an electronic pressure regulator. The device comprises the electronic pressure regulator and an air inlet pipe connected to a mixer. A pressure feedback pipe is connected between the electronic pressure regulator and the air inlet pipe. A water filter is connected with the middle of the pressure feedback pipe and installed below the electronic pressure regulator and the air inlet pipe. A water level sensor is arranged in the water filter and electrically connected with an alarm indicator lamp. A water drain valve is arranged at the bottom of the water filter. By connecting the water filter with water filtering and dust removing functions to the pressure feedback pipe between the air inlet pipe of the mixer and the electronic pressure regulator, vapor entering the pressure feedback pipe through the air inlet pipe falls down under the gravity to be condensed in the water filter; meanwhile, the water level sensor in the water filter is connected with the alarm indicator lamp, and when the water level in the water filter reaches a detection line, the alarm indicator lamp is switched on to remind a driver to drain water in time, so the problem that when water enters an electronic pressure regulator, reflection accuracy and sensitivity are lowered is solved.

Description

technical field [0001] The invention belongs to the technical field of automobile production and relates to a water ingress prevention device, in particular to an electric control voltage regulator water ingress prevention device. Background technique [0002] The electronically controlled voltage regulator is a microprocessor-based voltage regulator, which integrates an actuator with a high response frequency. CAN connection is used to communicate with the engine ECU, receive the engine ECU fuel pressure command and transmit the feedback information and operating parameters to the engine ECU for analysis and processing. Specific gas consumption and transient response to meet the performance requirements of equivalent combustion and lean combustion engines, so it is very important to ensure the stable operation of the electronically controlled voltage regulator. [0003] Since the electric air-conditioning regulator is very sensitive, if it encounters water, the accuracy an...

Problems solved by technology

[0003] Since the electric air-conditioning regulator is very sensitive, if it encounters water, the reflection accuracy and sensitivity of the electronically controlled voltage regulator will be affected, thereby affecting the performance of the engine

During the operation of the engine, although the air in the intake pipe of the engine is filtered to remove water, it is not 100% completely filtered, and some water vapor and impurities will enter from the intake pipe, and some water vapor and impurities are caused by the engine running process. At the same time, when the car is being washed or in a rainy and humid environment, water vapor may enter the intake pipe, and then enter the electronic control voltage regulator through the pressure feedback tube of the electronic control voltage regulator, affecting its work. , it is necessary to provide a device that can effectively prevent water from entering the electronically controlled voltage regulator, and this case arises from this
