37、 all the auxiliaries which affect the power output are fitted. 3.2.1 declared propeller shaft power power at the propeller shaft of an engine sold with complete propulsion units or at the coupling to the propeller shaft of an engine sold with reduction and/or reversing gears 3.2.2 declared crankshaf
38、t power power at the engine output shaft of an engine sold without reduction or reversing gears, or stern drives or sail drive units 4 Declarations The declared powers as defined in 3.2 shall be so named in manufacturers documentation.

40、5.1 Engine or propulsion system 5.1.1 The test engine or propulsion system shall be representative of the manufacturers production units. It shall be run-in according to the manufacturers recommendations and shall be fitted with an exhaust system. All auxiliaries fitted shall be listed and described
41、. 5.1.2 Carburettor wedges may be removed or added to maintain the carburettors at a normal running angle if the engine is tested in a horizontal position. 5.1.3 If the exhaust system as delivered is not complete, the back-pressure at the declared engine speed shall be within?0,75 kPa of the maximum
42、 back-pressure specified by the manufacturer at which the declared power can be achieved. If the exhaust system as-delivered is complete, the laboratory exhaust system shall maintain the exhaust pressure at the unit outlet within?0,75 kPa of the barometric pressure at the test bed. NOTE 1The maximum
43、 permissible back-pressure declaration is required by ISO 3046-1. 5.1.4 If the engine air inlet is connected to a laboratory air system, the system shall supply air to the engine within?0,75 kPa of the barometric pressure at the test bed. 5.1.5 For liquid-cooled engines, the temperature of the coola
44、nt at the raw-water inlet shall be maintained at 298 K?15 K (25?C?15?C), except that for engines with charge air cooler the temperature shall be maintained at 298 K?5 K (25?C?5?C). The coolant pressure shall not exceed 50 kPa. The coolant outlet temperature shall be within the range specified by the
45、 manufacturer if such a range is specified. 5.1.6 Fuel temperature at the inlet of the diesel engine fuel-injection pump shall be maintained at 313 K?3 K (40?C?3?C). NOTE 2These requirements do not apply to diesel engines running on intermediate or heavy fuels. 5.2 Fuels and lubricants 5.2.1 Fuels u
46、sed shall conform to the manufacturers specifications. 5.2.2 For spark-ignition engines, record the octane number determined in accordance with ISO 5163 (motor method) and ISO 5164 (research method), and density determined in accordance with ISO 3675. 5.2.3 For diesel (compression-ignition) engines,
47、 record the cetane number determined in accordance with ISO 5165, the density determined in accordance with ISO 3675 and lower calorific value. Use ISO-F-DMX (see ISO 8217) or equivalent fuel if compatible with the engine. 5.2.4 Lubricating oil used shall conform to the manufacturers recommendations
48、. Record lubricating oil type, grade and, if applicable, viscosity of the lubricant. 6 Test conditions 6.1 Operating conditions Test conditions shall be maintained as near to standard reference conditions as possible (see 3.2) in order to minimize the magnitude of the correction factor. Adjustments
49、shall be made before the test in accordance with the manufacturers instructions. No changes or adjustments shall be made during the test, except as indicated in the test procedure. 6.2 Generator and hydraulic systems The generator or alternator, hydraulic systems and similar systems intended for intermittent load only shall be operated under no-load conditions.
