1 Scope
This part of GB/T 6072 specifies the common measurement techniques of the main performance parameters of reciprocating internal combustion engines, in addition to the basic requirements defined in GB/T 21404-2008. This is to ensure that the required accuracy of measurement is achieved for comparison of the measured values with those values specified by the engine manufacturer. Where necessary, individual requirements may be given for particular engine applications.
This part of GB/T 6072 applies to reciprocating internal combustion engines for land, rail-traction and marine use.
It may be applied to engines used to propel road construction machines, industrial trucks, and for other applications where no suitable standards for these engines exist.
