GB/T 19055-2003 in English

《GB/T 19055-2003汽车发动机可靠性试验方法》由TC114（全国汽车标准化技术委员会）归口，TC114SC16（全国汽车标准化技术委员会发动机分会）执行，主管部门为工业和信息化部。
本标准规定了汽车发动机在台架上整机的一般可靠性试验方法，其中包括负荷试验规范（如交变负荷、混合负荷和全速全负荷）、冷热冲击试验规范及可靠性评定方法。本标准适用于乘用车、商用车的水冷发动机，不适用于摩托车及拖拉机用发动机。本标准可作为发动机制造厂和汽车制造厂之间交往的技术依据。

This standard specifies the general reliability test methods for complete motor vehicle engine on rack, including load test specification (such as alternating load, mixed load and full-speed full load), cool and hot shock test specification and reliability assessment method.
This standard is applicable to water cooling engines of passenger vehicles and commercial vehicles, not applicable to engines for motorcycles and tractors. This kind of engines is reciprocating, rotating and free of free piston, including spark-ignition engines and compression ignition engines, two-stroke engines and four-stroke engines, non-superchargers and superchargers (mechanical supercharging and turbo supercharging, water to air and air to air intercooling), is applicable to gasoline, diesel oil, natural gas, liquefied petroleum gas and alcohol powered engines.
The reliability test may be carried out according to methods specified in this standard for type approval of newly-designed or significantly-modified motor vehicle engines, certification of transfer-plant produced engines as well as quality inspection of currently produced engines.
This standard may also serve as technical basis for association between engine manufacturer and motor vehicle manufacturer.
