What is the use of the car switch
The main function of the automobile transfer switch is to adjust the working mode of the gearbox and the speed of the engine, thereby changing the driving performance and fuel economy of the vehicle . Specifically, the ECT (Electronic Controlled Transmission) switch on the car can achieve the following functions:
Improve vehicle performance : When the ECT switch is enabled, the vehicle enters motion mode. At this time, the engine speed is rapidly increased, the throttle response is more sensitive, the torque output is increased, and the acceleration performance of the vehicle is significantly improved. In this mode, the transmission shift point is usually set in the higher engine speed zone to ensure that the vehicle is able to consistently deliver high power output .
Automatic downshift : When driving downhill or at a lower speed, press the ECT switch to automatically downshift the vehicle to a lower speed. This not only ensures the safety of driving, but also reduces the burden on the brake system and avoids overheating and damage caused by frequent braking .
Fuel economy : When the ECT switch is off, the vehicle enters economy mode. At this time, the gear shift logic of the gearbox will be intelligently adjusted according to the actual road conditions and the driver's intention, keeping the engine speed in a relatively constant range, so as to achieve the purpose of saving fuel. After ECT is turned off, the relevant indicator on the dashboard also goes off .
Application scenario and Precautions :
Driving at high speeds : Enabling ECT mode provides more power and more direct throttle response when you need to overtake or drive at high speeds.
Everyday driving : When driving on ordinary roads or in cities, economy mode is recommended to save fuel and extend the life of the vehicle.
The working principle of the automobile switch is to control the on-off of the circuit by mechanical or electronic means. For example, the oil and gas transfer switch controls the fuel supply through complex mechanical and electronic operations to switch between gasoline and natural gas . Usage methods include:
In the cold start, the gas switch is set to the gas-diesel mode, and the hot start is performed.
When the water temperature rises to 70 degrees, switch the switch to natural gas mode.
When parked on the side of the road and the vehicle is idle, switch the gas switch back to the gas diesel mode to prevent the use of natural gas for a long time.
When stopping for a long time, set the switch to gas-diesel mode to ensure that the gas does not leak .
Care and maintenance advice
In order to ensure the normal operation of the car switch, the following points need to be noted:
Operation should be gentle and avoid prolonged continuous use.
Clean and check the switch regularly to prevent water vapor and dust from entering the interior.
Ensure that the wires do not touch the metal parts of the vehicle to prevent short circuits .
