Motorcycles -- Engine test code -- Net power

(Not available in French)

This standard has been revised by: ISO 4106:2012


ISO 4106:2004 specifies methods for evaluating the performance of engines designed for motorcycles 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. Used in conjunction with ISO 15550, it is applicable to reciprocating internal combustion engines (spark-ignition or compression-ignition) -- excluding free-piston engines -- and rotary piston engines, either naturally aspirated or pressure-charged and equipped with either mechanical pressure-charger or turbocharger.
