The Honda CVCC: The Little Engine That Beat the Clean Air Act - While Detroit Said It Was Impossible

The story of the Honda CVCC engine: when the 1970 Clean Air Act demanded huge cuts in vehicle emissions and many automakers argued the targets couldn't be met in time, a small company that had only recently started building cars came up with a clever solution. Honda's CVCC used a small pre-chamber with a rich mixture to ignite a lean mixture in the main chamber, and it met the 1975 emissions standards in EPA testing without a catalytic converter. We cover the Civic CVCC, the 1973 oil crisis, how other automakers responded, why catalytic converters and fuel injection eventually replaced the idea, and how the CVCC changed the image of Honda and Japanese cars in America.
