1.Precise Oil Pressure Control and Diversion for the VVT System
It receives real-time electrical signals from the Engine Control Unit (ECU) and, through the high-frequency response (response frequency ≥40Hz) of the internal high-precision spool (displacement accuracy up to 0.005mm), accurately controls the pressure (adjustment range: 0.6-12.5bar) and flow path of high-pressure engine oil. Based on the engine’s operating conditions (speed, load, cooling water temperature), it precisely distributes oil to the "timing advance chamber" or "timing retard chamber" of the camshaft phaser (camshaft position actuator), providing stable and controllable hydraulic power for camshaft phase adjustment. Ensuring a phase adjustment accuracy error of ≤±0.6°, it serves as the "hydraulic core" for the VVT system to achieve dynamic timing changes.
2.Dynamic Optimization of Camshaft Phase to Adapt to Audi Engine Characteristics
By regulating oil pressure to drive the rotation of the rotor inside the camshaft phaser, it changes the relative angle between the camshaft and crankshaft, thereby dynamically adjusting the intake valve opening/closing timing and valve overlap angle to match the dual usage scenarios of Audi models ("urban commuting + high-speed cruising"):
·Low-speed and low-load conditions (congested roads/start-up): Advances the intake valve opening time and increases the valve overlap angle to improve cylinder scavenging efficiency, boosting the engine’s low-speed torque by 6%-8% (e.g., for the Audi A4L 2.0T low-power version, torque at 1500rpm increases by approximately 20N·m), and optimizing power response during start-up lag and low-speed following;
·High-speed and high-load conditions (high-speed overtaking/full load): Retards the intake valve closing time and extends the intake stroke. Combined with Audi’s engine technologies such as "variable-displacement oil pump" and "AVS variable valve lift," this increases maximum power output (power increased by approximately 4%-5%) to meet power demands for high-speed driving and avoid high-speed power attenuation.
1.Audi OE-Level Adaptation with High Compatibility Covering Multiple Models
Manufactured in strict accordance with Audi’s original equipment (OE) technical standards, 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 a variety of mainstream Audi models (e.g., A3 Limousine, A4L B9, Q5L 40 TFSI). It can directly replace original parts without additional modification or adjustment. Compatible with multiple Audi engine series such as EA888 Gen3 (1.8T/2.0T) and EA211 1.4T, its compatibility far exceeds that of ordinary aftermarket parts "adapted for a single model," reducing the parts inventory pressure for repair businesses. The installation success rate is 100%, avoiding issues such as oil leakage (aftermarket part failure rate of approximately 13%), abnormal pressure, and timing disorder caused by poor adaptation.
2.Design for Severe Operating Conditions with Service Life Far Exceeding Aftermarket Parts
Targeting the characteristics of Audi engines—"high compression ratio (e.g., 11.7:1 for EA888 Gen3) and turbocharged high load"—enhancements are made in materials and structure:
·Valve Body Material: Adopts high-strength die-cast aluminum alloy specified by Audi (tensile strength ≥300MPa), with dual anti-rust treatment of "hard anodization + multi-layer epoxy resin coating," achieving salt spray corrosion resistance of 900 hours (vs. approximately 350 hours for aftermarket parts). It can withstand oil pressure above 12.5bar and extreme temperatures from -45℃ to 175℃ inside the engine;
·Spool and Seals: The spool is made of stainless steel (hardness ≥HV540) with excellent wear resistance; the seals are made of a composite material of oil-resistant and high-temperature-resistant fluororubber and polytetrafluoroethylene (PTFE) (temperature resistance range: -45℃~200℃), with strong resistance to oil sludge adhesion and chemical corrosion. It can effectively resist erosion from oil additives and turbocharged high-temperature products, 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.
