Motorcycle (L4) -a vehicle with three wheels asymmetrically arranged in relation to the longitudinal media plane with an engine cylinder capacity in the case of a thermic engine exceeding 50 cubic centimeter or whatever the means of propulsion a maximum design speed exceeding 50 kmh. (motorcycles with side cars or tricycles);

8. Motor Vehicle any vehicle propelled by a gasoline or diesel engine or by any other than human or animal power, constructed and operated principally for the conveyance of persons or the transportation of property or goods in a public highway or street open to public use;

9. New motorcycle/moped -any motor vehicle constructed entirely from new parts that has never been sold or registered with the LTO or with appropriate agency or authority, and operated on the highways of the Philippines, any foreign state or country;

10. Type Approval -the official ratification of the compliance of a vehicle type with applicable national or international regulations;

11. Vehicle Type -a category of power-driven vehicles which do not differ in such essentials as reference mass or weight, engine type, number of cylinders, body configuration, manner of transmission, fuel used and similar characteristics.

Sec. 5. Emission Limits for Type Approval of New Motorcycle and Moped - As a condition to issuance of the Certificate of Conformity (COC), all new motorcycle and moped types to be introduced in the market two (2) years after the approval of this Order shall comply with Tables 1, 1A, 2 and 3. [Ref: European Economic Community (EEC) Directive 97/24/EC(European Community)]

	Carbon Monoxide (CO)	Hydrocarbons (HC)	Oxides of Nitrogen (NOx)
<150	5.5	1.2	0.3
>150	5.5	1.0	0.3

Table 2
  Emission Limits for Motorcycle (L3)
  Level 2 with Effectivity Three Years After Effectivity of Level 1

Class (cc)	Emission Limits (g/km)

[2] Test cycle: ECE* R40 + EDUC** (emissions measured from all modes - sampling starts at T=0), with the maximum speed of 120 km/h)

* Economic Commission for Europe

** Extra Urban Driving Cycle

Table 3
Emission Limits for Moped (L1)

Effectivity Emission Limits (g/km) for Type Approval and Conformity of Production            

Level 1 - Two (2) years after the approval of this DAO
Level 2 - Three (3) years after implementation of Level 1

(1) The limit values for the masses of CO and HC+NOx are multiplied by a factor of 2 in the case of three-wheel mopeds;

(2) The limit for the mass of CO must be 3.5 g/km in case of three-wheel mopeds

The compliance of the above emission limits shall be determined using the test procedures laid down in European Community Directive ECE 40 as evidenced by a COC issued by the DENR.

SECTION 6. Issuance of Certificate of Conformity (COC). The application for a COC shall be submitted to the Environmental Management Bureau (EMB) by the Motor Vehicle manufacturer, assembler, importer or duly authorized representatives. It shall be accompanied by the following particulars in triplicate:

a. Complete and detailed description of motor vehicle and the engine;
b. Description of the emission control system installed in the motor vehicle;
c. Details of the fuel feed system;
d. Vehicle Type Approval System test result by DOTC/LTO (while the DOTC/ LTO is developing inspection capability of the motor vehicle type approval system test, the previous emission test results of pre-production engine vehicle type duly certified by the manufacturer of subject motorcyle/tricycle and moped shall be valid and sufficient; and
e. Other particulars which may be required by DENR.

SECTION 7. Validity of COC - For purposes of vehicle registration, the COC issued as a compliance with the above-mentioned emission limits shall be valid for six (6) years from the date of issue unless sooner revoked or suspended. In case of suspension, the 6-year validity period shall not be extended by the period of suspension. However, for those COCs issued under ECE Registration 40.01 type approval standards shall be valid until December 31, 2013.

SECTION 8. Emission Standards for In-Use Motorcycle/Tricycle and Moped - All in-use motorcycles/tricycles and mopeds registered on the dates indicated below shall comply with the following emission standards:
