Water injection application

Water injection application

Z uporabo sistema za vbrizg vode je mogoče doseči zmanjšanje emisij in povečanje učinkovitosti motorja z notranjim zgorevanjem. Eden ključnih  sestavnih elementov sistema   je črpalka s COR-tehnologijo prečrpavanja tekočine za povečanje tlaka oz. stiskanja tekočine (voda, zmes vode in  metanola) pred vbrizgavanjem v zgorevalno komoro cilindra. Tako dosežemo znižanje temperature motorja, nižjo temperaturo izpušnih plinov, zmanjšano porabo goriva in odpravimo ti »klenkanje« motorja, izboljšanje faz zgorevanja in zmanjšanje emisij NOx in CO2.

Pressure Boost Pump for ICE Water Injection
Stable flow over wide range of pressure
High efficiency for higher pressures

Pump properties

  • ADVANTAGE = HIGH Performance - SMALL size - LOW weight
  • 4 main components (motor rotor/stator | pump rotor/stator)
  • THERMOSET injection molding of dimensionally stable polymer material with high mechanical & thermal performance
  • Simultaneous engagement of complete gearing for high volumetric efficiency in middle pressure range (up to 20 bar)
  • Bi-directional operating mode (draining)
  • Particle resistance by dynamic axial displaceability of a motor rotor
  • Corrosion resistance
  • Compact dimensions
  • Motor in contact with fluid (wet design) – cooling ablility
  • Self adaptive tightening during life-time (performance stability)
  • Integrated BLDC Controller - LIN/CAN communication protocol
