Honda’s 1970s CVCC Engine Shows Pre-Chamber Ignition Didn’t Start in Formula 1

- Jalopnik says Honda applied pre-chamber-style combustion to the 1975 Civic CVCC decades before modern F1 popularized it.
- The CVCC system used a small chamber with a rich mixture to ignite a leaner main chamber charge.
- Honda’s design was influential enough to be licensed by several other automakers.
