FOREWORD

This Indian Standard ( Second Revision ) was adopted by the Bureau of Indian Standards, finalized by the Automotive Primemovers Sectional Committee had been approved by Engineering Division Council.

after the draft the Transport

This standard was first published in 1979 and was revised in 1986 to incorporate changes considered necessary during its usage. The present revision has been undertaken to standardize the procedure for measurement of carbon monoxide emissions during idling needed for regulatory, testing and type approval agencies to determine the exhaust carbon monoxide and examine its conformity to the values stipulated by the Government from time to time.

Like in earber standard, the emission limits for different category of vehicles have not been specified as they have already been specified under Central Motor Vehicle Rules and the vehicles fitted with spark ignition ( gasoline ) engines shall comply with those prescribed limits of carbon monoxide emissions at idling.

.

While preparing the standard, considerable assistance has been derived from the following:

IS0 3929 : 1995 Road vehicles - Measurement methods for exhaust gas emissions produced during inspection or maintenance

Annexure I of Ranganathan Committee Report

Details of Standards for Emission of Gaseous Pollutants from Petrol Vehicles and Test Procedures (Part 1 of Dot No. MOSTKMVIU TAP-115-116)

The committee responsible for preparation of this standard is given in Annex A.

In reporting the results of a test or analysis made in accordance with this standard, if the final value, observed or calculated, is to be rounded off, it shall be done in accordance with IS 2 : 1960 ‘Rules for rounding off numerical values ( revised )‘. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

Title

Glossary of terms relating to air pollution (first revision )

14554 : 1998 Automotive vehicles - Exhaust emissions - Apparatus for the measurement of carbon monoxide concentration from vehicles equipped with spark ignition engines at idling - Specification

3 TERMINOLOGY

For the purpose of this standard, the definitions given below in addition to those given in IS 4167 shall

apply.

3.1 Spark Ignition Engine (SI Engine)

Means an internal combustion engine in which the combustion of air/fuel mixture is initiated at given instant by a hot spot, usually an electric spark.

3.2 Idle Speed

Means,the engine speed, in revolution per minute with fuel system controls (accelerator and choke) in the rest

position, transmission in neutral and clutch engaged in the case of vehicles with manual or semiautomatic transmission, or with selector in park or neutral position, when an automatic transmission is installed, as recommended by the manufacturer.

3.3 Normal Thermal Conditions (NTC)

Means the thermal conditions attained by an engine and its drive line after a run of at least 15 minutes on a variable course, under normal traffic conditions.

3.4 Exhaust Emissions

Substances emitted to the atmosphere from any open- ing down stream from the exhaust port of a motor vehicle.

4 TEST PROCEDURE

4.1 The vehicle when subjected to the following test shall meet the limits of carbon monoxide stipulated by Government for that type of the vehicle.

4.2 Description of Test

4.2.1 Requirements of Instrumentation

4.2.1.1 The apparatus used for the measurement of Carbon monoxide (CO) shall meet the requirements specified in IS 14554, and the apparatus used for measurement of the speed shall have an accuracy of l 50 rev/mm.

4.2.1.2 The Instrument shall be prepared, used and maintained as recommended in the instrument manufacturer’s operation manual, and it shall also be serviced and calibrated at such intervals as to ensure accuracy.

4.2.1.3 Within a period of 4 hours before the lnstru- ment is first used, and each time the instrument is moved or transferred to a new environment, a ‘span and zero’ calibration shall be carried out using calibration gas. The calibration shall be performed away from the exhaust of motor vehicles whose engines are running.

IS 9057 : 1998

4.2.1.4 Ifthe sample handling system is not integral with the analyzer, the effectiveness of the condensate traps and all connections of the gas sampling system shall be checked. It shall be checked that filters are clean and filter holders are fitted with their gaskets and they are in good condition.

4.2.1.5 If the Instrument is not self-compensated for non-standard conditions of altitude and ambient temperature or not equipped with a manually controlled system of compensation, the span calibration shall be performed with the calibration gas.

4.2.1.6 It shall be ensured that the sample handling line and probe are free from contaminants and condensates.

4.2.2 Preparation of the Vehicle

4.2.2.1 It shall be ensured that the automotive ve- hicle exhaust system is leak proof and that the manual choke control has been returned to the rest position.

4.2.2.2 It shall be ascertained that the gas sampling probe can be inserted into the exhaust pipe to a depth of at least 300 mm. Owing to the exhaust pipe configuration, if it is not feasible to insert the probe to the stipulated depth of 300 mm, a suitable extension to the exhaust pipe(s) shall be provided and such a connection shall be leak proof.

4.2.2.3 The vehicle shall have attained normal thermal conditions as specified in 3.3, immediately prior to the measurement.

4.2.2.4 The vehicle idling speed (as recommended by the manufacturer) shall be measured and set as specified in 3.2 with all the accessories switched-off.

4.2.3 Measurement Procedure

4.2.3.1 Immediately before the measurement, the engine shall be accelerated to a moderate speed with

no load, maintained for at least 15 s and then returned to idle speed as set in 4.2.2.4.

4.2.3.2 While the engine idles, the sampling probe shall be inserted into the exhaust pipe to a depth not less than 300 mm.

4.2.3.3 The reading shall only be obtained after the engine speed stabilises.

4.2.3.4 The value of CO concentration reading shall be recorded.

4.2.3.5 In cases where gadgets or devices are incorporated in the exhaust system, for dilution of the exhaust, both carbon monoxide (CO) and carbon dioxide (COz) shall be measured using an instrument having facility to measure both (CO and CO2). If the total of the measured values of CO and CO2 ( TCO and Tco,) concentration exceeds 15 percent for four stroke engines and 10 percent for two stroke engines, the measured value of CO shall be considered as carbon monoxide emissions from the vehicle.

If it does not, the corrected value ( T corrected) shall be obtained as outlined below :

T corrected = TCO x 15/(Tc0 + TCOJ for four stroke engines

= Tco x lo/( Tco + Tco,) for two stroke engines

where

TCO = concentration of CO in percentage, and

TCO, = concentration of CO, in percentage.

4.2.3.6 In case the vehicle/engine has multiple exhaust outlets they shall be connected to a manifold arrangement terminating in a single outlet. If a suitable adopter is not available, the arithmetic average of the concentrations from the multiple pipes shall be used.
