How shipping industry can benefit from advanced Common Rail Technology and state of the art Exhaust Cleaning Systems in 4-Stroke Propulsion Plants.

International shipping is already, by far, the most carbon efficient mode of commercial transport in relation to freight capacity and distance travelled. In recent years, global and local regulations covering exhaust gas emissions have become progressively more stringent. In the case of 4-stroke marine engines, they concentrate on limiting emissions of oxides of nitrogen (NOx) and the content of sulphur in the fuel. Most recently, emissions of the greenhouse gas carbon dioxide (CO2) have also come under scrutiny. Ship operators, -designers and shipyards are faced with the legal demand to fulfill environmental sustainability while keeping operational costs as low as possible.

For MAN Diesel & Turbo’s current range of maritime 4-stroke engines, a major development focus has been the reduction of pollutant emissions while continuing to improve engine efficiency and thus lowering fuel consumption and operational costs. Especially further optimization of the combustion process needs to be aligned with the development of latest exhaust after treatment technologies.

The webinar will give insights how state-of-the-art technology leads the way to master both economic and ecological challenges. The speakers will reflect on how engine efficiency can be boosted by clever use of latest Common Rail Injection Systems (CR) and how MTD’s Selective Catalytic Reduction (SCR) solutions will help make shipping as clean as possible.

Our experts Lex Nijsen and Dr Gunnar Stiesch will round off their presentation with an outlook on further promising technologies (e.g. enhanced fuel switchover system for Sulphur compliance) and will be happy to answer your questions.

Presented by

Alexander (Lex) Nijsen,

Vice President, Head of 4-stroke Marine

Dutchman Alexander Nijsen, commonly known as Lex, has the overall responsibility of MAN Diesel & Turbo's 4-stroke Marine section. Until 2015, he had been the Head of Sales of the same business area. He started his professional career in 1990 as Engineer on board of tankers. Lex has then been working for MAN for almost 20 years - first at an MAN partner company in several service and sales related management positions, and then since 2006 directly at MAN Diesel & Turbo.

Dr. Gunnar Stiesch,

Vice President Advanced Engineering and Exhaust Aftertreatment, 4-Stroke Engines

Gunnar Stiesch has dedicated his professional life to combustion technology. After finishing his engineering studies at the Universities of Wisconsin (USA) and Hannover (Germany) with a doctoral degree, he held several positions within diesel engine development. He joined MAN Diesel & Turbo in 2008. Besides these duties, he shares his deep knowledge in technical combustion and large engine technology through an external professorship at Leibniz University Hannover.
