APRIL 24, 2013 — MAN Diesel & Turbo reports the 500th sale of its MAN 48/60 medium-speed engine. The milestone was reached with the order of two common-rail variants of the engine by Huta Marine of Jeddah, Saudi Arabia. They will be part of the diesel-electric system powering a self-propelled cutter suction dredge to be built in the Netherlands at an IHC Merwede Group shipyard.
The 48/60 engine was introduced in 2003 in both L- and V- versions as a major redevelopment of the successful predecessor series launched in 1989, characterized by increased output, reduced engine weight/width, and an optimised combustion that reduced both exhaust emissions and fuel consumption.
The 48/60 has been continuously developed ever since, notably including an upgrade to common-rail fuel injection in 2008 and full Tier II compliance in 2011, and more recently featuring a redesign of its cylinder head where a higher fuel injection pressure resulted in improved atomization and better combustion, ultimately reducing both fuel consumption and emission levels.
The 48/60 engine derives several, extra advantages from forming an integral part of the MAN Diesel & Turbo portfolio. The engine has many references where it has been integrated with the successful TCA turbocharger series while SaCoSone, MAN Diesel & Turbo's proven engine-management system, has also become standard issue.
