will a solenoid cause my voltage gauge
Will a solenoid cause my voltage gauge or valve in the circuit interfere with my display circuit when it acts ? The answer is yes . This interference is often caused by the fact that the solenoid valve is an inductive device , which will generate a spike voltage on the power supply line when it acts . Once the circuit design is unreasonable , it will be coupled to the control and signal lines , and eventually lead to circuit abnormalities. The fundamental reason is that the circuit layout and design are unreasonable , but there are many times because of the constraints can not be avoided . I have also encountered space problems . At this time , we need to isolate the inductive device such as solenoid valve from MCU to prevent mutual interference . The mode of isolating power module and optocoupler can be adopted . When inductive devices such as solenoid valve , relay and motor are involved in the general circuit , we should isolate the power supply and signal for the safety of the system . The common isolation can select the direct 12V to 5V power module , and 5V generally supplies power to MCU. For example , wide voltage input has many similar modules on the market .
The failure of automobile solenoid valve will directly affect the action of switching valve and regulating valve . When the solenoid valve of the car is broken , the following conditions will occur : the engine's idle speed is unstable , and the acceleration is weak . The car will stop when I shift into gear . The engine is easy to shut down or difficult to start . When the air conditioner is turned on, it will shut down . Automobile solenoid valve is the executive component of electronic control system . The carbon canister solenoid valve is a device installed on a car or motorcycle to reduce air pollution caused by fuel evaporation emissions and increase fuel efficiency at the same time .
When the engine starts , the oil vapor adsorbed in the carbon canister is delivered to the engine as fuel . The activated carbon canister of a car is usually designed as a long "box" , which is connected between the fuel tank and the bow engine intake manifold.
