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 pressure-charger or turbocharger.
Abstract
Overview
ISO 4164:2012 - Mopeds - Engine test code - Net power specifies standardized methods to evaluate the performance of moped engines (as defined in ISO 3833). The standard focuses on producing power curves, specific fuel consumption at full load vs. engine speed, and determining net power and net torque for spark‑ignition reciprocating and rotary piston engines (naturally aspirated or pressure‑charged). It is intended for engine test beds and reporting of corrected net power under defined standard reference conditions.
Key topics and technical requirements
- Scope and applicability
- Applies to moped engines (reciprocating internal combustion and rotary piston) but excludes free‑piston engines.
- Standard reference conditions
- Reference barometric pressure, temperature and humidity are defined for correction to a common baseline when reporting net power.
- Measurements and accuracy
- Torque dynamometer accuracy: ±1% (±2% for
