'''CVCC''', or {{Nihongo|2=複合渦流調整燃焼方式|'''Compound Vortex Controlled Combustion'''|3=''Fukugō Uzuryū Chōsei Nenshō Hōshiki''|lead=yes}}, is an [[internal combustion engine]] technology developed and [[trademark|trademarked]] by the [[Honda|Honda Motor Company]].<ref name=":0">{{Cite web|title=Honda Global {{!}} Introducing the CVCC / 1972|url=https://global.honda/heritage/episodes/1972introducingthecvcc.html|access-date=2020-12-15|website=global.honda|language=en}}</ref>

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.<ref name=":0" />

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]].<ref>{{cite journal |last1=Roeser |first = Justin |date=2022 |title=Milestones: The Journey of Honda in America.| url= https://images.squarespace-cdn.com/content/v1/583c9490be659429d110c269/1663197766454-U2WPYP6SW44BIP7T11BY/AVANTS~1.JPG |
