They allow a very wide rpm range with low fuel consumption and emissions.<\/p>\n<p>The 40L, 12-cylinder turbocharged diesel engine is available in five power ratings across three models. The 12AYM-WST models are available at 1,200mhp (882kW) at 1,850rpm and 1,400mhp (1,030kW) at 1,900rpm. The 12AYM-WET is available at 1,550mhp (1,140kW) at 1,840rpm and 1,659mhp (1,220kW) at 1,900rpm. The 12AYM-WGT produces 1,822mhp (1,340kW) at 1,940rpm.<\/p>\n<p>A new V-cylinder block configuration offers improved rigidity compared to previous models, with inspection ports providing easy access to connecting rod assemblies. A mechanical engine governor control and Yanmar&#8217;s own fuel system components further enhance reliability.<\/p>\n<p>Compliant with the latest IMO Tier II emissions regulations, the 12AY series has type approval by the six major classification societies.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Yanmar has recently launched its new V-12 engine, the 12AY.<\/p>\n","protected":false},"author":2,"featured_media":796,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[7],"tags":[],"sponsor":[],"class_list":["post-795","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-power-propulsion"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/posts\/795","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/comments?post=795"}],"version-history":[{"count":1,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/posts\/795\/revisions"}],"predecessor-version":[{"id":797,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/posts\/795\/revisions\/797"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/media\/796"}],"wp:attachment":[{"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/media?parent=795"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/categories?post=795"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/tags?post=795"},{"taxonomy":"sponsor","embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/sponsor?post=795"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
