Honda Plans to Employ Prechamber for Engines of Mass-produced Cars (1)
Honda Motor Co Ltd is putting its energy into the development of prechamber technologies for auto engines.
Nikkei xTech and Nikkei Automotive found that Honda plans to become ready for volume production within a few years. The company will prepare for Europe's strict environmental regulations by improving thermal efficiency and reducing CO2 emissions.
"We will employ it (prechamber) at the timing of making a new engine," said Ayumu Matsuo, managing executive officer of Honda R&D Co Ltd, who leads the development of power trains at Honda. He also said, "We will establish the technology within a few years," indicating that the company will start volume production in the near future.
In recent years, prechambers are being increasingly employed mainly for racing cars. Automakers are pushing forward with the research and development of prechambers behind the scenes in the aim of applying them to mass-produced cars, considering that they will improve thermal efficiency. The development race will probably become fierce in the world because Honda declared that it will focus on the development of prechamber technologies.
Honda built up a track record by employing a prechamber for a racing car for "World Touring Car Championship (WTCC)" and plans to apply it to commercially available cars.
Return of CVCC, which surprises world as measure against Muskie's law
Honda has high hopes for prechambers. It named the technology "i-CVCC," indicating that it is the return of "CVCC (compound vortex controlled combustion)," which surprised the world as a measure against the Muskie's law in the 1970s. The basis of the CVCC is the use of a prechamber.
