GB/T 8190.9-2010
AbolishedReciprocating internal combustion engines - Exhaust emission measurement - Part 9: Test cycles and test procedures for test-bed measurement of exhaust gas smoke emissions from compression ignition engines operating under transient conditions
往复式内燃机 排放测量 第9部分：压燃式发动机瞬态工况排气烟度的试验台测量用试验循环和测试规程
Application Summary AI generated
This standard specifies the test cycles and procedures for measuring exhaust smoke emissions from compression ignition engines under transient operating conditions on a test bed. It is applied in the development, certification, and type-approval testing of diesel engines used in vehicles, construction machinery, and industrial equipment to ensure compliance with emission regulations. The standard is critical for evaluating smoke opacity during dynamic load changes, such as acceleration or varying power demands.
