GB/T 21405-2008
ActiveReciprocating intenal combustion engines - Determination and method for the measurement of engine power - Additional requirements for exhaust emission tests in accordance with ISO 8178
往复式内燃机 发动机功率的确定和测量方法 排气污染物排放试验的附加要求
Application Summary AI generated
This standard specifies the additional requirements for determining and measuring engine power specifically during exhaust emission tests conducted in accordance with ISO 8178. It is applied to reciprocating internal combustion engines used in non-road mobile machinery, such as agricultural tractors, construction equipment, and industrial vehicles, ensuring consistent power measurement under regulated emission testing conditions. The standard ensures that power output data collected during emissions certification is accurate and comparable across different engine types and test facilities.
