Product Code:SAE J604
Title:Engine Terminology and Nomenclature-General
Issuing Committee:Sae Ic Powertrain Steering Committee
Scope:This SAE Recommended Practice is applicable to all types of reciprocating engines including two-stroke cycle and free piston engines, and was prepared to facilitate clear understanding and promote uniformity in nomenclature. Modifying adjectives in some cases were omitted for simplicity. However, it is good practice to use adjectives when they add to clarity and understanding.【英文标准名称】:StandardPracticeforConductinganInterlaboratoryStudytoDeterminethePrecisionofaTestMethod
