DANSK DS/ISO 4164 PDF

This International Standard specifies methods for evaluating the performance of engines designed for mopeds as defined in ISO 3833, in particular with a view to the presentation of power curves and specific fuel consumption at full load as a function of engine speed, for net power assessment. It is applicable to reciprocating internal combustion engines (spark-ignition) - excluding free-piston engines - and rotary piston engines, either naturally aspirated or pressure-charged and equipped with either mechanical pressurecharger or turbocharger.
