The big displacement of two-wheeled(Vh>250mL) and three-wheeled(Vh>250mL) motorcycle is very small part of Chinese market, just about thousands.

The Standards for Emissions of Motorcycle (China Ⅳ draft)

Item Framework in Stage Ⅳ Remarks

Type Ⅰtest

test method

Two-wheeled motorcycles with and without side-car: GTR2(in general)

Two-wheeled and three-wheeled mopeds :ECER47Right three-wheeled motorcycles:ECER40

/

limits Equal to (EU)No.168/2013 /

Type Ⅱtest The test method and limits are required. /

Type Ⅲ test

It is not allowed that any fuel, lubrication oil or crankcase gases escape to the atmosphere from the crankcase gas

ventilation system in the draft. But the influence/suitable on Chinese market from the type Ⅲ test in EU Ⅳ draft is

being investigated.

/

The Standards for Emissions of Motorcycle (China Ⅳ draft)

Item Framework in Stage Ⅳ Remarks

Type Ⅳtest

Test method SHED Test: Diurnal+Hot Soak<2.0g/test /

BWC BWC test is required The result of approval test would be used for COP.

Durability Under discussion /

Type Ⅴtest

Test cycle The AMA cycle is used in the draft. And the SRC is studying now. /

Mileage Equal to (EU)No.168/2013 /

Noble Metal Content test

The Noble Metal Content (Pt: platinum Rh: rhodium Pd: palladium) of catalyst is

required to be analyzed.

The test result should be equal to the manufactures’

declare.

Motorcycles with CI engines

The test method and limits are listed in the draft. /

Comments on OBD(GTR NO.XX)

1

OBD emission thresholds: We support that setting the limits and offering sets of OBD threshold limits as alternatives for contracting parties. But we don’t hope that it is required in OBD Ⅰ. We suggest it would be required in OBD Ⅱ or OBD X.

2 Monitoring significant reduction of propulsion unit torque would not be requiredin OBDⅠ.

3 The functional requirements, such as ABS, could be required in OBD Ⅰ.

4 The requirement of (IUPR) should not be required in OBD1 .

5 The fault codes which influence the emissions should be consistent with ISO standards, but the fault codes which influence business secret may be not.

6 The categories of vehicle, L1 to L5, would be required OBD Ⅰ in Chia Stage IV.

We hope that the OBD Ⅰ test would be simple. The reason is that Chinese motorcycle industry is so huge, and most of motorcycles are using carburetor. The cost of changing from carburetor to Fuel Injector is too high. Suggestions as follow:
