As a core executive component of the VVT system in Nissan HR-series engines, it receives real-time signals (speed, load, coolant temperature) from the ECU, and drives camshaft phase adjustment through an internal hydraulic mechanism. It precisely controls the opening/closing timing of the intake valve, breaking the limitation of fixed valve timing—"weak low-speed torque and limited high-speed power"—and maximizing the performance potential of the HR16DE engine.
(2) Scenario-Specific Power Optimization
1.Low-Torque Enhancement for Commuting Conditions: When the speed is < 2400rpm (startup, following in urban traffic jams), it delays the closing time of the intake valve, and uses airflow inertia to improve cylinder charging efficiency. This increases torque output by 13%-18%, improving the problem of "sluggish startup" and weak low-speed acceleration, and adapting to the frequent start-stop needs of daily commuting.
2.Power Improvement for High-Speed Conditions: When the speed is > 4000rpm (high-speed overtaking, accelerated cruising at constant speed), it optimizes the opening phase of the intake valve in advance, reduces intake resistance, and increases air intake per unit time. This boosts power output by 9%-14%, ensuring sufficient power reserve during high-speed driving and making overtaking and acceleration more smooth.
1.Micron-Level Precision Matching: Developed for Nissan’s HR16DE 1.6L engine (equipped in major models such as Nissan Sylphy and Tiida), the sprocket’s tooth profile accuracy is controlled within ±0.004mm, and the fit tolerance between the shaft hole and camshaft is only ±0.002mm. It fully conforms to the original factory’s installation interface and VVT system communication protocol, allowing direct replacement without any adaptation or adjustment. This fundamentally avoids timing deviation, fault codes (e.g., P0011/P0012), and transmission noise caused by dimensional discrepancies.
2.Cross-Model Compatibility: In addition to the target models, it is also compatible with other Nissan models based on the same HR-series engine platform (such as Nissan Sunny and Livina). There is no need to stock separate parts for different models, which significantly reduces the inventory pressure of repair shops and lowers the spare parts procurement cost for users with multiple Nissan vehicles. Its compatibility is superior to ordinary VVT sprockets designed for a single model.
1.16-Dimensional Comprehensive Testing: From raw material composition analysis and tensile strength testing to finished product dynamic timing accuracy testing (error ≤ 0.3° crank angle), 8-minute airtightness pressure retention testing, -45°C to 400°C high-low temperature cycle testing, and 350,000-kilometer durability testing (simulated fault-free operation), the entire process complies with ISO/TS16949 and Nissan QS9000 standards, with a product qualification rate of 99.96%.
2.Precision Calibration of Brand-New Parts: All parts are 100% newly produced without any refurbishment or repair traces. Before leaving the factory, the flow accuracy of the internal hydraulic oil circuit is calibrated one by one (flow error ≤ 5%), and the response time to ECU commands is ≤ 0.09 seconds. This completely eliminates power fluctuations and fuel consumption increases caused by seal aging and oil circuit blockage in refurbished parts.
