PART 89_CONTROL OF EMISSIONS FROM NEW AND IN-USE NONROAD 

COMPRESSION-IGNITION ENGINES--Table of Contents

 

              Subpart D_Emission Test Equipment Provisions

 

Sec.  89.301  Scope; applicability.





    (a) This subpart describes the equipment required in order to 

perform exhaust emission tests on new nonroad compression-ignition 

engines subject to the provisions of subpart B of part 89.

    (b) Exhaust gases, either raw or dilute, are sampled while the test 

engine is operated using an 8-mode test cycle on an engine dynamometer. 

The exhaust gases receive specific component analysis determining 

concentration of pollutant, exhaust volume, the fuel flow, and the power 

output during each mode. Emission is reported as grams per kilowatt hour 

(g/kw-hr). See subpart E of this part for a complete description of the 

test procedure.

    (c) General equipment and calibration requirements are given in 

Sec.  89.304 through 89.324. Sections 89.325 through 89.331 set forth 

general test specifications.

    (d) Additional information about system design, calibration 

methodologies, and so forth, for raw gas sampling can be found in 40 CFR 

part 1065. Examples for system design, calibration methodologies, and so 

forth, for dilute exhaust gas sampling can be found in 40 CFR part 1065.
