Camless Engine


  • What is the Camless Engine?
    • It replaces Camshaft with Smart Valve Actuation
    • Intake & Exhaust Valves control electronically
    • The implementation of fully variable intake/exhaust valve timing and lift control in Spark Ignition engines can significantly improve
  • Characteristics
    • Fuel Efficiency (10%)
    • Engine Torque increase
    • Pollutant Emission reduction
  • Schematic of the Camless Engine Valve Actuator System
