Section 2 Essential Requirements


201. Engine identification


1. Each engine is to be clearly marked with the following information:

(1) engine manufacturer's trademark or trade-name;

(2) engine type, engine family, if applicable;

(3) a unique engine identification number; and

(4) CE marking, if applicable.

2. These marks must be durable for the normal life of the engine and must be clearly legible and indelible. If labels or plates are used, they must be attached in such a manner that the fixing is durable for the normal life of the engine, and the labels/plates cannot be removed without destroy- ing or defacing them.


3. These marks must be secured to an engine part necessary for normal engine operation and not nor- mally requiring replacement during the engine life.


4. These marks must be located so as to be readily visible to the average person after the engine has been assembled with all the components necessary for engine operation.


202. Exhaust Essential requirements


1. Propulsion engines are to be designed, constructed and assembled so that when correctly installed and in normal use, emissions are not exceed the limit values obtained from the following table:


Table 12.1 limit values of exhaust emission

2. Where A, B and n are constants in accordance with the table, ĀÀ is the rated engine power in kW and the exhaust emissions are measured in accordance with the ISO 8178-1.

3. For engines above 130 kW, either E3 (IMO) or E5 (recreational marine) test cycles may be used.

4. The reference fuels to be used for the emissions test for engines fuelled with petrol and diesel are to be of those accepted by this Society.


203. Durability


1. The manufacturer of the engine is to supply engine installation and maintenance instructions, which if applied, is to mean that the engine in normal use will continue to comply with the above limits throughout the normal life of the engine and under normal conditions of use.


2. This information is to be obtained by the engine manufacturer by use of prior endurance testing, based on normal operating cycles, and by calculation of component fatigue so that the necessary maintenance instructions may be prepared by the manufacturer.


3. The normal life of the engine is considered to mean:

(1) inboard or stern drive engines with or without integral exhaust: 480 hours or 10 years, which- ever occurs first;

(2) outboard engines: 350 hours or 10 years, whichever occurs first.


204.

Owner's manual


1. Each engine is to be provided with an owner's manual in english or languages, which may be de- termined in which the engine is to be used. This manual is to :

(1) provide instructions for the installation and maintenance needed to assure the proper of the engine to meet the requirements of 203.(durability); and

(2) specify the power of the engine when measured in accordance with the ISO 8665. image
