The Netherlands: Yanmar to Exhibit CHS Diesel Engines at SMM 2012

Yanmar to Exhibit CHS Diesel Engines at SMM 2012

Yanmar Europe will exhibit Yanmar commercial high-speed (CHS) diesel engines for marine applications at the SMM 2012 trade fair in Hamburg. The SMM takes place from 4 to 7 September. It is the largest trade fair for the international shipping industry.

At the SMM Yanmar will display its new V-12 engine; 12AY.

With easy installation and maintenance, the purpose-built 12AY is ideal for offshore support vessels, ferries, tugs, commercial fishing craft and other demanding applications. A key element of the improved performance and efficiency is a new staggered injection nozzle and patented combustion chamber design. They allow a very wide rpm range with low fuel consumption and emissions.

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 (882 kW) at 1,850rpm and 1,400mhp (1,030 kW) at 1,900rpm. The 12AYM-WET is available at 1,550mhp (1,140 kW) at 1,840rpm and 1,659mhp (1,220 kW) at 1,900rpm. The 12AYM-WGT produces 1,822mhp (1,340 kW) at 1,940rpm.

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’s own fuel system components further enhance reliability.

Compliant with the latest IMO Tier II emissions regulations, the 12AY series has type approval by the six major classification societies.
