1.Precise Oil Control for the VVT System
It receives real-time electrical signals from the Engine Control Unit (ECU) and, through high-frequency displacement of the internal spool, accurately controls the flow path, volume, and pressure of high-pressure engine oil. Based on engine operating conditions (such as speed, load, and water temperature), it precisely distributes oil to the "timing advance" or "timing retard" oil chambers of the camshaft phaser, providing stable and controllable hydraulic power for valve timing adjustment. It serves as the "power switch" for the VVT system to achieve dynamic timing changes.
2.Dynamic Optimization of Camshaft Phase
By regulating oil pressure to drive the rotation of the rotor inside the camshaft phaser, it changes the angle of the camshaft relative to the crankshaft, thereby dynamically adjusting the opening/closing timing of the intake valves and the valve overlap angle. For example: under low-speed and low-load conditions (e.g., urban traffic congestion), it advances the intake valve opening time to improve cylinder charging efficiency, enhance low-speed torque, and optimize the power response of Honda models during start-up and following traffic; under high-speed and high-load conditions (e.g., high-speed overtaking), it retards the intake valve closing time to extend the intake stroke, increase maximum power, meet power demands for high-speed driving, and achieve a balance between power and fuel consumption across the entire speed range.
3.Adaptation to Engine Operation Under Multiple Working Conditions
It dynamically optimizes valve timing parameters for different engine operation scenarios: during cold starts, it shortens the valve overlap angle to reduce mixture leakage, improve start-up success rate and idle stability, and avoid vibration and stalling risks during cold starts; during idle speed, it precisely controls oil flow to reduce VVT system energy consumption, lowering idle fuel consumption and engine noise (by approximately 3-4 decibels); during rapid acceleration, the spool response time is ≤0.25 seconds, quickly switching oil flow direction to adjust the camshaft phase to "power mode," shortening power lag time and ensuring smooth and powerful acceleration—aligning with the "high-rev power characteristics" of Honda engines.
1.Honda OE-Level Adaptation for Worry-Free Installation and Compatibility
Manufactured in strict accordance with Honda’s original equipment (OE) technical standards for engines, the valve body interface size, spool stroke, and electrical signal connector specifications are fully matched to the cylinder head oil passages and ECU signal system of specific Honda models (e.g., some Accord and Civic models equipped with R20A/K24Z engines). It can directly replace original parts without additional modification or adjustment, avoiding issues such as oil leakage (failure rate of approximately 12%), abnormal pressure, and timing disorder caused by poor adaptation of aftermarket parts. The installation success rate is 100%, while ensuring high compatibility with Honda’s original vehicle systems.
2.High-Durability Design for Long Service Life
The valve body is made of high-strength aluminum alloy specified by Honda, with a dual surface treatment of "hard anodization + anti-corrosion coating," capable of withstanding oil pressure above 12bar and extreme temperatures from -40℃ to 160℃ inside the engine—adapting to complex climates and long-term high-load working conditions. The spool seal uses fluororubber material that is oil-resistant and high-temperature-resistant, with strong resistance to oil sludge adhesion, effectively resisting erosion from oil oxidation products and avoiding pressure loss caused by seal failure. Tests show that its service life can reach 80,000-100,000 kilometers under normal operating conditions, far exceeding the 40,000-50,000 kilometers of ordinary aftermarket parts, reducing the frequency of subsequent replacements and maintenance costs.
3.High Control Precision for Improved Engine Performance and Economy
Adopting Honda OE-calibrated spool and coil design, the oil flow control error can be limited to within ±2% (vs. approximately ±6% for ordinary aftermarket parts), ensuring the accuracy of valve timing adjustment. Through optimized timing control, the fuel combustion efficiency of Honda engines can be improved by 3%-5%, with a comprehensive fuel consumption reduction of 0.2-0.4L/100km (for example, for the Honda Accord 2.4L model, urban fuel consumption is reduced from 10.2L/100km to approximately 9.8L/100km). At the same time, it reduces unburned fuel and nitrogen oxide (NOx) emissions, helping the vehicle stably meet strict emission regulations such as China’s National VI B and the EU’s Euro 6d, and avoiding annual inspection issues caused by non-compliant emissions.
