Two or three-wheels motor vehicles: maximum design speed, torque and net engine
1991/0371(COD)
1) OBJECTIVE
To harmonize national laws and establish a type-approval
procedure with regard to maximum design speed (measurement
method), maximum torque (measurement method) and maximum net
engine power (permissible limit value and measurement method) of
two- or three-wheeled motor vehicles.
2) CONTENTS
1. This Directive forms part of the type-approval procedure for
two- or three-wheeled motor vehicles covered by Council Directive
92/61/EEC.
2. The vehicles covered by the Directive are divided into the
following types:
* mopeds: two- or three-wheeled vehicles fitted with an engine
having a cylinder capacity not exceeding 50 cm3 and a maximum
design speed of not more than 45 km/h;
* motorcycles: two-wheeled vehicles with or without sidecar,
fitted with an engine having a cylinder capacity of more than
50 cm3 and/or having a maximum design speed of more than
45 km/h;
* motor tricycles: vehicles with three symetrically arranged
wheels fitted with an engine having a cylinder capacity of more
than 50 cm3 and/or a maximum design speed of more than
45 km/h;
* quadricycles: four-wheeled vehicles whose engine cylinder
capacity does not exceed 50 cm3, whose maximum design speed
is not more than 45 km/h and whose unladen mass is less than
350 kg are considered to be mopeds, while other quadricycles
are classed as tricycles.
3. Requirements relating to the method of measuring maximum
design speed and covering test conditions and procedure and the
maximum speed of the vehicle.
4. Requirements relating to the maximum permissible power and
methods of measuring maximum torque and maximum net engine power:
* a study is planned to check whether there is any connection
between accidents and maximum engine power of more than 74 kW;
* specific requirements concerning spark-ignition engines for
mopeds, motorcycles and tricycles and relating to:
* accuracy of torque and power measurements under full load;
* the measurement test and the test report;
* the correction factors for torque and power;
* the maximum torque and maximum net power measurement
tolerances.
5. Procedure for adapting requirements to technical progress.
6. Procedure for granting type-approval:
* the application for type-approval is submitted by the
manufacturer to the competent authority of a Member State;
* the competent authority grants type-approval in respect of the
maximum design speed, the maximum torque and the maximum net
power if these conform to the technical requirements of this
proposal and to the data provided by the manufacturer;
* to this end, it fills in the type-approval certificate
contained in the annex to the proposal.
7. The requirements relating to the maximum design speed, the
maximum torque and the maximum net power form part of a list of
47 characteristics set out in Council Directive 92/61/EEC all of
which have to be complied with for two- or three-wheeled motor
vehicles to be approved and marketed in the Community.
8. Restrictive clause: in their territory Member States may
reject the first registration and subsequent registrations of
vehicles with a maximum net power of more than 74 kW.
