Smokeless diesels for Spirit

摘要

In a working partnership between Carnival Corporation and Waertsilae Corporation, the 86,000-ton cruise ship Carnival Spirit will be fitted with what is claimed will be the cruise industry's first smokeless diesel engines. Initially, two of the ship's six Waertsilae 9 L46D engines will be modified with the new "smokeless" engine technology. They will use a common rail fuel injection system that enables injection pressures to be kept sufficiently high at all engine speeds—even at the lowest levels—to ensure clean combustion with no visible smoke emissions.
