Context paragraphs:
CVCC: CVCC is a trademark by the Honda Motor Company for an engine with reduced automotive emissions, which stood for "Compound Vortex Controlled Combustion".  The first mention of Honda developed CVCC technology was done by Mr. Soichiro Honda February 12, 1971, at the Federation of Economic Organizations Hall in Otemachi, Chiyoda-ku, Tokyo.  Honda's engineers at the time, Mr. Date conferred with Mr. Yagi and Mr. Nakagawa about the possibility of creating lean combustion via a prechamber, which some diesel engines utilized.  The first engine to be installed with the CVCC approach for testing was the single-cylinder, 300 cc Honda EA engine used in the Honda N600 hatchback in January 1970.  This technology allowed Honda's cars to meet Japanese and United States emission standards in the 1970s without a catalytic converter.  A type of stratified charge engine, it first appeared on the 1975 "ED1" engine.  As emission laws advanced and required more stringent admissible levels, Honda abandoned the CVCC method and introduced PGM-FI, or Programmed Fuel Injection on all Honda vehicles.  Some vehicles in Japan had a combination of electronically controlled carburetors, called PGM-Carb on specific, transitional Honda D, E and ZC engines.
