Section 169.1. Purpose

Latest version.

This chapter provides a procedure for the assessment of transient and steady-state smoke emissions from vehicular diesel engines using an engine dynamometer cycle which simulates normal operating conditions. While intended for engine development and evaluation, it is similar to a procedure which has been used for regulatory approval by the United States government.

The provisions of this § 169.1 adopted August 26, 1977, effective August 27, 1977, 7 Pa.B. 2432.
