These engines are designed from the drawing board for maritime purposes. As a result, the engine has inspection covers, loose liners and a number of features such as readable thermometers. The engine also has water-cooled manifolds and turbos, which means that the heat emission in the engine room remains limited. The design ensures, for example, that maintenance can easily be done on board and that the engine can be overhauled on board if necessary.
The Baudouin engines are equipped with a common rail injection system with piezo injectors. Common rail technology has been used in the car world since the arrival of EURO III. This brought a major improvement in fuel consumption and engine torque.
A common rail engine has several injection moments per cycle. In addition, different amounts can be injected at a time. This is recorded in the so-called ‘engine mapping’. Due to the higher pressures, the fuel is finer and better distributed. This results in more efficient combustion, resulting in less formation of NOx and soot particles.
Also, due to the use of common-rail technology, the permitted back pressure after the turbo is many times higher. This makes a compact after-gas treatment package work.
The dimensions of the DOC-DPF-SCR combi for the large V12 engine of 1650 hp are very compact. The orientation of the package is flexible, so it can be positioned to fit into most engine rooms.
Finally, the Stage-V waste gas treatment package is also easy to maintain, because it can be screwed open and the elements can then be easily inspected and replaced. This makes it a really good solution for the maritime world!
The 6M26.3 engine is a 6-in-line and has a displacement of 16 liters. The larger 12M26.3 is a 32 liter V12. The models are completely improved versions of the proven and well-known M26.2 predecessor.
