Stage-V Baudouin marine engines

The M26.3 family is finished Stage-V certified by Motors Baudouin.

 

Why a Baudouin Stage-V engine?

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 be easily carried out on board and that the engine can be overhauled on board if necessary.

The overall performance of the engine is without a doubt solid. The documentation of the engine has also been expanded and options such as a PTO are possible.  

These are the capabilities:

6M26.3-V IWA: e6*2016/1628*2016/1628AC4/D*0001*00
12M26.3-V IWP: e6*2016/1628*2016/1628PV4/D*0004*00

Common rail technology, what is the advantage of this?

The Baudouin engines are equipped with a common-rail injection system with piezo injectors. Common rail technology has been used in the automotive world since the arrival of EURO III. That brought a big 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 creates a more efficient combustion with 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 allows a compact post-gas treatment package to work. This saves considerable installation space and costs.  

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 in a way that it should fit into most engine rooms.

Finally, the Stage-V waste gas treatment package is also easy to maintain, because it can be unscrewed and the elements can then be easily inspected and replaced. So a really good solution for the maritime world!  

The 6M26.3 engine is a 6-inline engine 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.

Operating system

The engine is equipped with an ECU from Bosch. This ECU communicates with a Comap ID DCU. The Comap ID DCU is again coupled to the bridge panel and simultaneously to the control of the after-treatment system.

The after-treatment system is linked to the optional industrial PC that connects to the internet via a GSM modem.

After-treatment system Stage V: build-up

The complete after-treatment system, shown in the adjacent figure, consists of:

  • The DOC with inlet and outlet cone
  • The modular emission aftertreatment system
  • The urea mixer mixing pipe
  • The urea dosing package
  • The main tank pack
  • The wire harness
  • The hydraulic package
  • The control box

The system concept will be attached to the turbo outlets, each turbo outlet will have its own DOC and mixer. The package contains 10 elements; (2 rows of 5). The Modular Emissions Aftertreatment System is a standardized modular emissions package developed for marine, generator sets and other large industrial applications.

Different emission technologies can be fitted within the same design, SCR (SCR only for Marine IMO TIER III), SCR+ (with DOC and ASC for TIER 4 F and EU Stage IV), a stage V package (with DOC, DPF, SCR, ASC) and SCR + ASC + OC for gas engines and greenhouses.

The temperature sensors, NOx and oxygen sensor, the pressure drop across are an integral part of the package. System components are selected to maintain emissions in line with requirements, taking into account typical lifecycle expectations for marine and CHP applications

The service intervals can be synchronized with the engine maintenance and overhaul intervals (provided the correct fuel and lubricating oil is used).

The catalytic converter service is clearly structured. The system is designed to last. All elements can be easily removed by hand and no special tools are required. The weight of an individual catalytic converter element is less than 20 kg. The fasteners are made of stainless steel, but even after many heating and cooling cycles, they can be easily removed and replaced with new bolts if damaged or overloaded.

The complete exhaust package is made of premium stainless steel quality: 316 (L).

It is corrosion resistant both inside and out and resistant to urea, ammonia, sea water and many other unknown chemical components that may be present in exhaust gases.

The assembly is supplied with a DN PN6 flange set of the selected pipe diameter. The flanges are not welded to the pipes, which allows installation according to the customer's wishes. ABATO is happy to make a specific design of the inlet/outlet of the DOC - mixing pipe - SCR for each project in conjunction with the customer's needs. This way we can design the system in the engine room. All our major components come with a 20 year spare parts availability guarantee. The figure below shows the 12M26.3 with the compact integrated after-treatment system

The DOC with inlet and outlet cone

The DOC substrate (diesel oxidation catalyst) is made of metal Fecraloy® and coated with a powerful and stable oxidation coating. The coating enables and promotes passive regeneration of the DPF (diesel particle filter) and, if necessary for emergencies, also active regeneration through Diesel HC (hydrocarbon) dosing.

The DOC catalytic converter comes with an inlet and outlet cone that tapers the DOC to the diameter of the exhaust bend and compensator after the turbo.

At the inlet of the DOC is a 1 meter stainless steel straight tube with the connection ports for the sensors and actuators listed below:

  • Temp 1 sensor
  • Back pressure sensor exhaust system
  • DO NOTx 1 sensor
  • Diesel dosing unit

The assembly is supplied with a DN PN6 flange set, which is correlated with the pipe diameter. The flanges are not welded to the pipes, which allows installation according to the customer's wishes.

The urea mixer or mixing pipe

The system is always supplied with a 2-stage low pressure drop mixer. This technology enables airless urea dosing. This method is cost effective as a compressor is not required. Because no compressed air is required, the energy required to operate the system and thus the CO2footprint of the system is virtually zero.

  • There is no overdose of urea
  • There is no need for an oversized catalyst pack because we can use the total surface area of ​​the catalyst;
  • System diagnostics improve thanks to homogeneous reading of exhaust emissions

 

The urea dosing package

Electronic control unit

The dosing system uses an ECU as the center of the system. This Electronic Control Unit (ECU) has been developed as a link between the engine and the emission aftertreatment system. The ECU controls the AUS (Urea/AdBlue) dosing, tanks and pumps while constantly monitoring performance, engine operating conditions and pressure drop across the exhaust. A number of parameters are stored in the ECU, according to the Stage-V regulation. Each engine has its own individual controls.

Most important features
