1. Precise Oil Flow Control
Receive electrical signals from the vehicle’s Engine Control Unit (ECU) to drive the internal electromagnetic coil, which further controls the opening/closing angle or on/off state of the oil valve. This adjusts the flow rate of engine oil delivered to key components (such as the engine’s cylinder head, crankshaft bearings, and turbocharger), ensuring each part gets the right amount of lubrication.
2. Real-Time Oil Pressure Regulation
Work with oil pressure sensors to form a closed-loop control system. When the ECU detects abnormal oil pressure (too high or too low), it sends a signal to the Oil Valve Solenoid to adjust the valve’s opening degree—reducing the opening to lower pressure if it’s too high, or increasing the opening to raise pressure if it’s too low—maintaining oil pressure within the optimal range for engine operation.
3. Lubrication On-Demand for Engine Start-Up
During cold starts, the engine’s oil viscosity is high, and traditional mechanical valves may have delayed lubrication. The Oil Valve Solenoid can quickly respond to ECU signals (within milliseconds) to open the oil valve, accelerating oil circulation to critical friction parts (like piston rings and camshafts), reducing dry friction wear at start-up.
4. Coordinate with Variable Valve Timing (VVT) Systems
Many modern engines are equipped with Variable Valve Timing (VVT) technology, which relies on oil pressure to adjust the timing of intake/exhaust valves. The Oil Valve Solenoid acts as the "switch" for oil supply to the VVT system: it controls the timing and amount of oil entering the VVT actuator, enabling the actuator to adjust the valve timing accurately, thereby optimizing engine power output and fuel efficiency.
1. Faster Response Than Mechanical Valves
Mechanical oil valves rely on oil pressure or mechanical linkage for operation, with a response time of hundreds of milliseconds to seconds. In contrast, the Oil Valve Solenoid is driven by an electromagnetic coil, responding to ECU signals in milliseconds—this rapid response ensures timely adjustment of oil flow/pressure, adapting to sudden changes in engine working conditions (such as sudden acceleration or load increases).
2. Higher Control Precision
The opening degree of the Oil Valve Solenoid can be adjusted steplessly or in multiple stages according to the strength of the electrical signal (PWM pulse width modulation signal). For example, during high-speed engine operation, it can slightly reduce the oil valve opening to avoid excessive oil pressure (which wastes engine power); during low-speed heavy loads, it can increase the opening to enhance lubrication. This precision control is impossible with traditional mechanical valves.
3. Reduced Engine Power Loss
Mechanical oil valves often maintain a fixed oil flow/pressure, which may lead to excessive oil supply (and thus unnecessary power consumption) under certain conditions (such as low-speed cruising). The Oil Valve Solenoid adjusts oil supply on demand: it only provides the required oil flow/pressure based on real-time engine conditions, minimizing the power consumed by the oil pump and improving overall engine efficiency.
4. Enhanced Engine Durability
By ensuring precise oil pressure and timely lubrication, the Oil Valve Solenoid effectively reduces friction between engine components. For example, it prevents insufficient lubrication (caused by low oil pressure) which leads to metal-to-metal contact, and avoids excessive oil pressure (which causes seal damage or oil leakage). This stable lubrication environment significantly extends the engine’s service life.
5. Support for Engine Electrification and Intelligence
As engines develop toward electrification (e.g., hybrid engines) and intelligent control, the Oil Valve Solenoid—with its ability to communicate seamlessly with the ECU—can integrate into the vehicle’s overall electronic control system. It can work with other sensors (temperature, speed sensors) to implement adaptive lubrication strategies, laying the foundation for more efficient and low-emission engine operation.
