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.

The CVCC (Compound Vortex Controlled Combustion) engine debuted in 1975 and was offered alongside the standard Civic engine. The optional 53 hp (39 kW) CVCC engine displaced 1488 cc and had a head design that promoted cleaner, more efficient combustion.

The CVCC system has today been superceded by innovations such as the three-way catalytic device and electronic fuel injection. But through the enhancement of a reciprocating engine using technologies available in the 1970s, Honda was able to meet stringent regulatory requirements.

2022年7月14日 · Honda’s success in the U.S.—its largest market across the globe—began with the Civic, and especially the novel and efficient CVCC engines it came equipped with. To …

The Civic CVCC is more than just a charming little car that drives better than most mid-1970s cars. Its combination of smart engineering and environmental concern laid the blueprint that made Honda on

2024年2月16日 · This compact car, launched in 1973, was not only a response to the growing demand for fuel-efficient vehicles but also a pioneering model in terms of emissions control technology. The Civic CVCC, which stands for "Compound Vortex Controlled Combustion," was designed to meet stringent emissions standards without the need for a catalytic converter.

2022年6月8日 · With CVCC, Honda became the first carmaker to comply with provisions stated in the US Clean Air Act of 1970, even fulfilling the 1975 threshold where all passenger cars were to reduce emissions 90% versus 1970 levels. Honda’s feat established the carmaker as a force to reckon with, and left Detroit’s big 3 looking like spoiled bickering kids.

2022年11月10日 · Having said that, there’s no question that the Civic CVCC was a genuine milestone car in the history of the American automobile industry. It convincingly showed that it was possible to meet three seemingly impossible criteria (super compact size, super efficient engine, low-emissions), right here and right now.

2022年10月11日 · The CVCC engine was not only clean-burning, it got great mileage, and was ranked the most fuel efficient car in the U.S. for four consecutive years, 1975-78. Additionally, the fact that it didn’t need a catalytic converter proved to be a boon at a time when some gas stations still only offered leaded fuel (lead is damaging to catalytic ...

2023年1月28日 · All of the Honda Civic’s success can be pin pointed to one special model featuring an engineering advancement that poised it perfectly for the American audience in the ‘70s. We’re taking a look back at the Honda Civic CVCC, the car that gave Honda that foothold it needed to stand where it is today.
