The core functions of the Engine Oil Control Valve (OCV Valve) can be divided into the following two major modules, covering lubrication system protection and Variable Valve Timing (VVT) collaborative control:
1. Lubrication System Pressure Regulation
①Dynamic Oil Pressure Limitation
· Installed in the oil passage at the outlet of the oil pump, it limits the maximum oil pressure through mechanical or electromagnetic adjustment to prevent oil passage leakage, seal damage, or oil pump overload caused by excessive oil pressure.
· Automatically triggers a protection mechanism in case of abnormalities to avoid lubrication failure due to insufficient oil pressure in the engine.
②Pressure Stability Assurance
·Balances the output pressure of the oil pump with system requirements to ensure stable oil pressure at all lubrication points (such as crankshaft bearings and camshafts) and reduce wear.
2.Variable Valve Timing (VVT) Control
① Dynamic Adjustment of Valve Timing
· Receives ECU pulse signals through the solenoid valve, controls spool displacement to switch oil passages, and drives the VVT controller to adjust the camshaft angle, optimizing valve opening and closing timing.
·Achieves optimal intake/exhaust efficiency under different engine operating conditions, increasing torque by 10-15% and reducing fuel consumption by 5-8%.
②Multi-condition Adaptability
·Delays valve timing at low speeds to improve idle stability, and advances timing at high speeds to enhance power output.
3.Fault Chain Protection
·Valve body failure can cause abnormal oil pressure (too high/too low), leading to rich mixture, power loss, stalling, or excessive emissions.
·The integrated diagnostic function can monitor oil pressure fluctuations through OBD to warn of jamming risks in advance.
(Note: Some models integrate the OCV valve with the ECU to further optimize response speed.)
As a core component of the lubrication system and Variable Valve Timing (VVT) system, the product advantages of the Engine Oil Control Valve (OCV Valve) are mainly reflected in the following technical dimensions:
1.Precise Pressure Regulation Capability
①Dynamic Oil Pressure Adjustment
·Controls the spool displacement through solenoid valve pulse modulation signals to adjust the oil pressure in real time, with the error range controlled within ±0.1bar, ensuring stable pressure in the lubrication system.
·Compared with traditional mechanical valves, the response speed is increased by more than 50%, which can avoid oil passage leakage or component damage caused by excessive oil pressure.
②VVT System Collaborative Optimization
It links with the camshaft phase sensor to dynamically adjust the intake/exhaust valve timing angle, increasing engine torque by 10-15% while reducing fuel consumption by 5-8%.
2.Material and Reliability Advantages
① Extreme Environment Resistance Design
· The valve body is made of hard anodized aluminum alloy, which can withstand high temperatures of 150℃ and oil corrosion, with a service life of over 200,000 kilometers.
·The return spring is made of high-carbon steel, and its fatigue resistance is 3 times better than that of ordinary springs.
②Fault Protection Mechanism
·Built-in redundant oil circuits can automatically switch to a backup channel when the main oil circuit is blocked, avoiding the risk of engine oil cutoff.
·Triggers the ECU degradation mode in case of abnormalities to limit the rotation speed and protect the engine.
3. Energy Efficiency and Environmental Performance
①Improvement of Fuel Economy
·Reduces pumping losses by optimizing the valve timing, lowering fuel consumption by 3-5% under NEDC conditions.
·Reduces high-temperature carbonization of engine oil, extending the oil change interval to 15,000 kilometers.
②Emission Control
· Precise adjustment of the valve overlap angle reduces HC/NOx emissions by 20%, meeting the National VI B standard.
4.Modularity and Compatibility
① Multi-type Adaptability
·Provides four major series of valve bodies such as single-seat, double-seat, and sleeve types, covering more than 90% of engine models.
·Supports integrated design (e.g., integration with ECU), reducing the complexity of wire harnesses.
②Convenience of Maintenance
·Plug-in circuit interface design allows valve body replacement in only 10 minutes without the need for professional equipment calibration.
