YSMXYPZKRCar Turbocharger Valve 1628ZT 3M5Q-9E882-BA Fit For Peugeot 206 307 1007 Fit For Citroen C2 C3 Xsara 1.4 2.0 HDI 1999-2009
Main highlights- 5. Adapt to multiple working conditions: Support adaptive adjustment modes (such as high-altitude compensation and cold start protection), automatically increase the boost pressure by 0.1-0.2 Bar (compensating power attenuation of 10% -15%) when the altitude is above 3000 meters, limit the boost pressure to<0.6 Bar during cold start, and protect the engine thermal load.
- 4. Extend turbine life: When the engine decelerates rapidly (speed drop rate>500rpm/s), the control valve quickly releases pressure (pressure release time<100ms), reduces turbine speed fluctuations (peak speed drop ≤ 10%), reduces bearing wear (wear amount reduced by 40%), and the turbine life can be extended to more than 250000 kilometers.
- 3. Optimize fuel economy: Under high-speed conditions (>3000rpm), by precisely controlling the exhaust gas flow rate (adjustment accuracy ± 5%), the turbine efficiency is maintained in the high-efficiency range of 75% -85%, and the air-fuel ratio (λ=1.05-1.1) is adjusted in conjunction with the ECU, reducing fuel consumption by 0.5-1.2L per hundred kilometers.
- 2. Improve low-speed responsiveness: When the engine speed is less than 2000rpm, the control valve opens the bypass valve in advance (delay angle ≤ 5 ° CA) to reduce turbo lag (turbo pressure rise time shortened by 0.3-0.5 seconds), allowing the torque platform to intervene 200-300rpm in advance and increase low-speed torque by 15% -20%.
- 1. Precise adjustment of boost pressure: Through electromagnetic or pneumatic control (response time<50ms), the boost pressure fluctuation can be controlled within ± 0.02Bar, avoiding engine knock caused by excessive pressure (such as limiting peak pressure to the safe range of 1.2-1.5Bar), and improving power output stability (power fluctuation ≤ 3%).
