卡特彼勒船舶动力系统已经开发出一种新的船用双燃料发动机平台的商业海洋市场的MAK™M 34 DF。发动机拥有的额定功率为500千瓦，每缸720和750​​转，柴油和天然气模式，作为M 32 C系列发动机将共享相同的足迹。M 34（DF）将能够使用天然气作为一种替代船用柴油或大型和复杂的洗涤装置排放控制区（ECA）运费。预计为2014年10月第一台发动机交付。

“我们很高兴能够继续我们的承诺，提供商业海洋市场带来创新，高效的解决方案，”说，麦产品定义经理卡斯滕·西伯格。“我们的客户想要省油，持续推进产品运营灵活性IMO和EPA稳压水域的，我们的目标是超越他们的期望与M 34 DF发动机。”

即将到来的燃油中的硫和氮氧化物法规经委会的带动下，将提供M 34 DF的灵活性，监管及/或较小的管制区域作业的渔船到机房或废气系统没有大的变化，配套发动机安装的易用性和简单性，认证。虽然设计用于液化天然气（LNG），船用柴油和重油的无限操作，M 34 DF气模将达到业界领先的效率。

“这是我们重要的DF，M 34和M 32 C共享相同的足迹功能，在同一个系统接口。M 34（DF）旨在为运营商提供业界领先的热效率最低的总运营成本，“说，麦产品定义经理德特勒夫Kirste。该引擎提供优化的负载响应，负载稳定度，除了众多的支持功能，如远程监控和发动机系统的诊断，帮助引擎运营商与他们的日常维修和维护工作。我们的目标是保持典型的MaK船用发动机的属性，如可靠性，安全性和效率，同时努力的发动机设计，易于维修和维护。“

发动机缸径为340毫米和460中风，被设计成气体的电气和机械推进系统的应用，尤其是在海上和货运分部的首选。发动机的设计提供新的实时燃烧监测，柔性凸轮轴技术功能以及较低的气门和一些创新的监测和组件的解决方案，以确保最大的安全，在操作过程中。

新麦双燃料发动机，，卡特彼勒将提供服务和支持，包括安装和应用，系统集成的支持，再加上客户和船员培训。M 34（DF）将在德国罗斯托克通客户验收测试和分级审批，并通过麦卡特彼勒经销商网络将被出售。

去年12月，卡特彼勒船舶解释其扩展LNG产品线最终将提供客户更容易，更昂贵的安装引擎，也将提供具有成本效益的改造方案，在现有船舶的发动机。状态监测将用于船用发动机提供无论他们在哪里工作，提供系统的简单，方便的服务和维护。

Caterpillar Marine Power Systems has developed a new marine dual-fuel engine platform for the commercial marine market, the MaK™ M 34 DF. The engine boasts a power rating of 500 kW per cylinder at 720 and 750 rpm in diesel and gas modes, and will share the same footprint as the M 32 C engine series. The M 34 DF will be capable of running on natural gas as an alternative to marine diesel oil or large and complex scrubber installations for shipping in Emission Control Areas (ECA). First engine deliveries are foreseen for October 2014.

“We’re pleased to continue to deliver on our commitment to bring innovative, efficient solutions to the commercial marine market,” said Carsten Seeburg, MaK product definition manager. “Our customers want a fuel-efficient, sustainable propulsion product with operational flexibility for both IMO and EPA regulated waters and we’re aiming to exceed their expectations with the M 34 DF engine.”

Driven by upcoming fuel sulfur and NOx regulations in ECA, the M 34 DF will provide flexibility for vessels operating in regulated and/or lesser regulated areas without major changes to the engine room or exhaust gas system, supporting the ease and simplicity of engine installation and certification.  Although designed for unlimited operation on LNG, marine diesel oil and heavy fuel oil, the M 34 DF will reach industry- leading efficiency in gas mode.

“It was important for us that M 34 DF and M 32 C share the same footprint features, and the same system interfaces. The M 34 DF was designed to provide operators with industry-leading thermal efficiency for lowest total cost of operation,” said Detlef Kirste, MaK product definition manager. “The engine offers optimized load response and load stability in addition to numerous support features, such as remote monitoring and engine system diagnostics, helping engine operators with their daily service and maintenance work. Our target was to keep the typical MaK marine engine attributes like reliability, safety and efficiency while striving for an engine design that is easy to service and maintain.”

With a bore of 340 millimeters and stroke of 460, the engine was designed to be the preferred choice for gas electrical and mechanical propulsion applications notably in the offshore and cargo segments. The engine design features new real-time combustion monitoring, Flexible Camshaft Technology functionality as well as a lower valve train and several innovative monitoring and component solutions to ensure maximum safety during operation.

Caterpillar will offer service and support for the new MaK dual fuel engine, including installation and application, system integration support, plus customer and crew training. The M 34 DF will be pass customer acceptance tests and classification approvals in Rostock, Germany and will be sold through Caterpillar’s MaK dealer network.

Last December, Caterpillar Marine explained its extended LNG product line will ultimately provide customers with engines that are easier and less expensive to install, and will also offer a cost-effective retrofit option for engines in existing ships. Condition monitoring will be offered for shipboard engines no matter where they are operating, providing system simplicity for easier service and maintenance.
