This Code provides rules for testing, and for the computation and tabulation of the results of tests for all types of reciprocating internal combustion engines, in order to determine power and fuel consumption. The objects of testing under this Code is the determination of: (a) Net power output, and (b) Rate of fuel consumption and/or energy input. Application of this Code is limited to engine assemblies as defined by Code Engine Assembly: In the absence of specified stipulations the engine assembly to be tested shall consist of the engine complete with essential apparatus for self sustained continuous operation. Generally these consist of the equipment required for: fuel introduction, air induction, (i.e. scavenging or supercharging), ignition, lubrication, and primary engine and charge air cooling.
