What is the Function of an Engine Solenoid Valve?

The function of an engine solenoid valve: A solenoid valve uses the electromagnetic force generated by an electric current flowing through a coil to attract the valve core. It is divided into normally open and normally closed types, commonly used to cut off the flow of substances such as oil, water, and gas. It works in conjunction with electrical equipment like pressure and temperature sensors to achieve automatic control. Its characteristic is that it can operate normally under vacuum, negative pressure, and zero pressure, but the diameter generally does not exceed 25mm. More details are as follows: 1. The principle of an engine solenoid valve: When energized, the electromagnetic coil generates an electromagnetic force that lifts the closing component from the valve seat, opening the valve; when de-energized, the electromagnetic force disappears, and the spring presses the closing component onto the valve seat, closing the valve. 2. Automotive solenoid valves also include distributed direct-acting solenoid valves, direct-acting solenoid valves, and pilot-operated solenoid valves.

What is the method to reactivate ETC after removal?

ETC reactivation method after removal: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth is on". If "Tag invalid" appears when inserting/removing twice without the electronic tag attached, this is normal and doesn't affect activation. Alternatively, you can directly press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth and open the corresponding mobile APP (usually there's a download QR code on the electronic tag), then enter the device activation interface. Click "Device Connection" and wait patiently for the "Connection successful" prompt. After successful connection, upload a photo of the vehicle's front to complete activation. ETC installation process: When receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-removal button on the back of the OBU - a red light will briefly illuminate, and the OLED screen will display "Tag invalid" or "Please insert card", indicating the device is functioning normally. Clean the windshield, ensuring the glass surface is smooth, clean and dry. Then peel off the OBU's adhesive backing and stick it to the installation position, pressing firmly for 2-3 minutes to remove air bubbles. Insert the ETC card with its front facing the driver and back facing the windshield, making sure the chip is properly inserted into the OBU device.

What Causes the Oil Light to Illuminate When There's No Oil Shortage?

The reasons for the oil light illuminating when there's no oil shortage are as follows: 1. Engine temperature is too high. Prolonged aggressive driving keeps the engine in a high-temperature, high-load state. Although the oil level is sufficient, excessive thinning of the oil due to high temperature causes it to leak through the clearances, leading to a drop in oil pressure. 2. Oil pump failure. Excessive wear or improper assembly of the oil pump components creates excessive clearances, causing abnormal operation. If the oil pump fails to deliver oil or delivers insufficient oil, the oil light will activate. 3. Incorrect oil selection. If the owner uses oil with a lower grade or viscosity that doesn't match the manufacturer's specifications, oil leakage may occur, resulting in insufficient oil pressure and triggering the warning light. 4. Improper clearance between the crankshaft's main and connecting rod bearings. Owners who have undergone major engine repairs should check whether there was an issue during assembly—excessive tightness can increase oil pressure, while excessive looseness can reduce it. If the oil light comes on, it's crucial to address the issue promptly. Continuing to drive without identifying the cause may lead to severe engine damage, such as cylinder scuffing or crankshaft seizure, necessitating a major engine overhaul.
