Regulation No. 24

UNIFORM PROVISIONS CONCERNING,

        I. THE APPROVAL OF COMPRESSION IGNITION (C.I.) ENGINES WITH REGARD TO THE EMISSION OF VISIBLE POLLUTANTS

        II. THE APPROVAL OF MOTOR VEHICLES WITH REGARD TO THE INSTALLATION OF C.I. ENGINES OF AN APPROVED TYPE

        III. THE APPROVAL OF MOTOR VEHICLES EQUIPPED WITH C.I. ENGINES WITH REGARD TO THE EMISSION OF VISIBLE POLLUTANTS BY THE ENGINE

IV. THE MEASUREMENT OF POWER OF C.I. ENGINE

1. SCOPE

1.1 This Regulation applies to,

                 1.1.1 PART I. The emission of visible exhaust pollutants from C.I. engines which are intended for fitting to road vehicles.

                 1.1.2 PART II. The installation into road vehicles of C.I. engines that have been type approved to Part I of this Regulation.
                 1.1.3 PART III. The emission of visible exhaust pollutants from a motor vehicle that is fitted with an engine that has not been separately type approved to Part I of this Regulation.

        1.2 The secondary scope of this Regulation is the ECE procedure to be applied when only the power output by C.I. engines is to be measured.

2. DEFINITIONS COMMON TO PARTS I, II and III
        2.1 For the purpose of this Regulation the following definitions are common to Parts I, II and III:
        2.2 "Net power" means the power of a C.I. engine as defined in annex 10 to this Regulation;
