Exhaust Emission - Rcd2 Durability - Beta Marine Beta 50 Operator's Maintenance Manual

Emission Durability
IN RESPECT TO THE RECREATIONAL CRAFT DIRECTIVE 2013/53/EU
AND IN PARTICULAR RESPECT TO EXHAUST EMISSIONS.
The engine must be installed, maintained and operated within the parameters detailed in the
Operator's Maintenance Manual. Maintenance must use approved materials, parts and consumables.
Should the engine lie unused for a period in excess of 6 months it must be inhibited otherwise it
will deteriorate with resulting decrease in performance. See also the Winterising and Laying Up
procedures in the Operator's Maintenance Manual.
The fuel settings of the diesel injection system must not be tampered with otherwise the guarantee
will be invalid and the performance may fall outside prescribed limit. Such adjustment cannot be
allowed under the terms of the emission certification.
Performance of the engine depends upon the use of correct fuels, lubricants and inhibitors. These
are fully detailed in the Operator's Maintenance Manual.
Particular attention must be paid to the installation with respect to the exhaust system. The system
must be designed so that water cannot back feed into the engine. The run must be such that
the back pressure at the engine manifold does not exceed the limit detailed in the Operator's
Maintenance Manual. Wet (water injected) exhaust systems must be at least the bore mentioned
in the Operator's Maintenance Manual and should the run be excessive this bore must be increased
accordingly. Back pressure is measured at the outlet of the engine manifold before the water
injection bend or dry bellows.
Our experience has proven that properly installed and maintained engines hold their performance
without major mishap even when running hours exceed those mentioned in the Recreational Craft
Directive. It is the owners / users responsibility to ensure that the engine continues to function
properly and any malfunction must be immediately investigated. The Trouble Shooting section as
detailed in the Operator's Maintenance Manual is particularly helpful in this respect.
Engine performance, especially with respect to erratic running, exhaust condition, low power output
and high oil consumption are indications of engine conditions that may result in emissions outside
the prescribed limits and must therefore be investigated and rectified immediately. Only genuine
Beta Marine or Kubota approved parts must be used.
