Variable Intake Manifold with an Integrated Rotary Valve

High Output is Achieved by Switching Intake Ports According to Driving Conditions

  • Cost and weight are reduced by applying resin intake manifolds and variable valves
  • Engine output is improved by optimally controlling air flow to cylinder chambers by switching passages having different length
  • To improve engine output, a rotary valve, which has low intake pressure loss, is used for a variable intake portion
