13、tandardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the ri
14、ght to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Internationa
15、l Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as
16、an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 3046 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rig
17、hts. ISO 3046-1 was prepared by Technical Committee ISO/TC 70, Internal combustion engines. This part of ISO 3046 cancels and replaces ISO 3046-1:1995, ISO 3046-2:1987 and ISO 3046-7:1995, which have been technically revised and their technical content combined. ISO 3046 consists of the following pa
18、rts, under the general title Reciprocating internal combustion engines Performance: Part 1: Declarations of power, fuel and lubricating oil consumptions, and test methods Additional requirements for engines for general use Part 3: Test measurements Part 4: Speed governing Part 5: Torsional vibration
19、s Part 6: Overspeed protection Annex A forms a normative part of this part of ISO 3046. Annexes B, C and D are for information only. BS ISO 3046-1:2002vi Introduction This part of ISO 3046 establishes one “Satellite” standard of the ISO engine power measurement standards, the use of which enables on
20、e to avoid the disadvantages due to the existance of many similar, but different, ISO standards for the definition and determination of engine power. It uses the “Core” and “Satellite” approach. The “Core” standard, ISO 15550, contains the requirements that are common to all engine applications wher
21、eas this part of ISO 3046 contains as a “Satellite” standard those requirements that are necessary to tailor power measurement and declaration to suit the particular engine application as defined in clause 1. This part of ISO 3046 is intended to be applied in conjunction with the “Core” standard ISO
22、 15550 in order to completely specify the requirements for the particular engine application. The “Satellite” standard therefore is not a document that can stand alone standard but is intended to be accomplished by the requirements laid down in the “Core” standard ISO 15550 in order to become a comp
23、lete standard. The structures of both, the “Core” and the “Satellite” standard have been drafted in a very similar way in order to ensure easy use. The advantage of this approach is that the use of standards for the same or similar engines used in different applications will be rationalized and the
24、harmonization of standards in the course of revision or development will be ensured. For engines used on board ships and offshore installations which have to comply with the rules of a classification society, it is recommended that the additional requirements of the classification society be observe
25、d. It is recommended that the relevant classification society be stated by the customer prior to placing the order. For non-classed engines, any additional requirements are subject to agreement between the manufacturer and customer. If requirements from the regulations of any other authority (e. g.
26、inspecting and/or legislative authority) have to be met, it is recommended that the relevant authority be stated by the customer prior to placing the order. It is recommended that any further requirements be subject to agreement between the manufacturer and customer. BS ISO 3046-1:2002 1Reciprocatin
27、g internal combustion engines Performance Part 1: Declarations of power, fuel and lubricating oil consumptions, and test methods Additional requirements for engines for general use 1 Scope This part of ISO 3046 specifies the requirements for the declaration of power, fuel consumption, lubricating oi
28、l consumption and the test method in addition to the basic requirements defined in “Core” standard ISO 15550. This part of ISO 3046 defines codes for engine brake power in accordance with “Core” standard ISO 15550, in order, where necessary, to simplify the application of the statements of power and
29、 to facilitate communication. This applies, e.g., to statements of power used on engine data plates. It applies to Reciprocating Internal Combustion (RIC) engines for land, rail-traction and marine use. This part of ISO 3046 may be applied to engines used to propel road construction and earth-moving
30、 machines, industrial trucks, and for other applications where no suitable International Standard for these engines exists. It is a “Satellite” standard and is intended to be applied in conjunction with “Core” standard ISO 15550 only, in order to completely specifiy the requirements for the particul
31、ar engine application. NOTE In addition to the terms used in the three official ISO languages (English, French and Russian), this International Standard gives, in Table 3, the equivalent terms in German; these have been included at the request of Technical Committee ISO/TC 70 and are published under
32、 the responsibility of the member body for Germany (DIN). However, only the terms given in the official languages can be considered as ISO terms. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of I

40、2002 clause 5 apply. 6 Test method 6.1 General Test method 1 in accordance with 6.2 of ISO 15550:2002 applies. The manufacturer shall specify which of the following procedures is applicable to the engine for this test method: a) power adjustment; b) power correction. BS ISO 3046-1:2002 36.2 Adjusted
41、 engines 6.2.1 The test power may be determined, where necessary, using equations (1) to (6) (see 10.3) in one or more of the following ways: a) by adjusting the ISO power from the standard reference conditions to the test ambient conditions; b) by adjusting the declared service power from the site
42、ambient conditions to the power under the test ambient conditions; c) by making the test power equal to the declared service power and testing under conditions altered artificially in accordance with 6.2.5 in order to simulate the site ambient conditions; d) by testing under conditions simulating so
43、me of the site ambient conditions in accordance with 6.2.5 and adjusting the declared service power to allow for the remaining differences. NOTE Power adjustment by using equations (1) to (6) is only permissible if the turbocharging equipment or timing of the engine is not changed or modified for si
44、te ambient conditions. 6.2.2 When adjusting the power, the engine manufacturer shall state which of the formula references given in Table 2 shall be used. If there is no suitable formula reference for power adjustment shown in Table 2, the method of adjustment shall be agreed in writing by the manuf
45、acturer and customer. 6.2.3 If a turbocharged engine at the declared power and under the standard reference conditions attains neither the turbocharger speed limit nor the exhaust gas temperature limit at the turbine inlet, nor the maximum combustion pressure, the manufacturer may declare substitute
46、 reference conditions as specified in 10.3.2 for the power adjustment. 6.2.4 When adjusting the declared power on site for the test ambient conditions, results may be attained where, e.g., the maximum combustion pressure in the engine cylinder exceeds the permitted value. In this case, the engine te
47、st shall be carried out at a power considered safe by the manufacturer, at which the permitted value is not exceeded. The values of the engine parameters corresponding to the required power may be extrapolated from the measured values by a method agreed upon between the manufacturer and customer. 6.
48、2.5 Engine tests may be carried out under ambient conditions created artificially to simulate site ambient conditions by one of the following: a) altering the air temperature at the engine inlet by artificial heating; b) altering the coolant temperature at the inlet of the charge air cooler, etc.; c
49、) other appropriate methods considered safe by the manufacturer.
