Variable Cylinder Managementとは 意味・読み方・使い方

Variable Cylinder Management (VCM) is Honda's term for a variable displacement technology. It uses the i-VTEC system to disable one bank of cylinders during specific driving conditions (for example, highway driving) to save fuel. The 2008 Accord takes this a step further allowing the engine to go from 6 cylinders, down to 4, and further down to 3 as the computer sees fit. Honda's VCM uses overhead cams as opposed to DaimlerChrysler's Multi-Displacement System and General Motors' Active Fuel Management pushrod systems.
