Alcance y aplicabilidad

This standard applies to motorcycles and mopeds equipped with spark-ignition engines, compression-ignition engine positive three-wheeled motorcycles, and hybrid electric motorcycles and hybrid electric mopeds. It is not applicable to vehicles exclusively fueled by gaseous fuels or alcohol fuels. This standard is mandatory for manufacturers seeking type approval in China.

Requisitos técnicos

The standard specifies the fuel consumption limits for various categories of motorcycles and mopeds, categorized by engine displacement and power-to-mass ratio (PMR). It defines specific limit requirements for two-wheeled and side three-wheeled motorcycles with both manual and automatic transmissions, as well as for positive three-wheeled motorcycles and mopeds. For hybrid electric vehicles, the standard introduces new fuel consumption limit requirements, aligning them with the corresponding limits for conventional vehicles. The standard also details the criteria for same type judgment, specifying the parameters for vehicle, engine, and pollutant control system characteristics that must be identical for type extension. Manufacturers must ensure their products meet these specified limits to obtain type approval. The standard references GB 14622-2026 for testing conditions and procedures.

Métodos de ensayo

The standard outlines several measurement methods for fuel consumption, including flow measurement, volumetric measurement, weighing measurement, and the carbon balance method. For hybrid electric vehicles, specific testing procedures are defined based on the vehicle's chargeability (OVC/NOVC) and the presence of manual mode selection. The testing involves chassis dynamometers and specific driving cycles as defined in GB 14622-2026.

Preguntas frecuentes

What products are regulated under GB 15744-2026?

GB 15744-2026 regulates the fuel consumption limits and measurement methods for motorcycles, mopeds, positive three-wheeled motorcycles, and hybrid electric motorcycles/mopeds.

Are there any updates from the previous version of GB 15744?

Yes, the 2026 version adds requirements for hybrid electric motorcycles and mopeds, introduces the power-to-mass ratio (PMR) for categorization, and updates the fuel consumption limit tables and measurement methods.

How is fuel consumption measured for hybrid electric vehicles under this standard?

Fuel consumption for hybrid electric vehicles is measured using specific procedures based on whether the vehicle is off-vehicle chargeable (OVC) or not (NOVC), and whether it has a manual mode selection function, involving tests under different state of charge conditions.
