Reduced-emissions engine by Honda
A Honda Civic engine with CVCC
CVCC, or Compound Vortex Controlled Combustion (Japanese: 複合渦流調整燃焼方式, Hepburn: Fukugō Uzuryū Chōsei Nenshō Hōshiki), is an internal combustion engine technology developed and trademarked by the Honda Motor Company.[1]
The technology's name refers to its primary features: Compound refers to the use of two combustion chambers; Vortex refers to the vortex generated in the main combustion chamber, increasing combustion speed, and Controlled Combustion refers to combustion occurring in a timely, controlled manner.[1]
The engine innovatively used a secondary, smaller auxiliary inlet valve to feed a richer air-fuel mixture to the combustion chamber around the spark plug, while the standard inlet valve fed a leaner air-fuel mixture to the remainder of the chamber, creating a more efficient and complete combustion.
