Guidance document on Off-Road Compression-Ignition Engine Emission Regulations: chapter-1

A. Introduction

This guidance document provides information about the requirements of the Off-Road Compression-Ignition Engine Emission Regulations. A first version of this guidance document was published in March 2006 after the original regulations covering these engines were published in February 2005.Footnote1 This guidance document has since been modified to reflect the changes to the regulations as a result of the Regulations Amending the Off-Road Compression-Ignition Engine Emission Regulations (DORS/2011-261), published in December 2011.

In general, Canadian manufacturers of off-road compression-ignition engines and importers of engines and machines containing these engines have legal obligations under these regulations. Compression-ignition engines are typically diesel-fueled engines; however, the regulations are not limited to this particular fuel. For simplicity, these engines will be referred to as diesel engines in the remainder of this guidance document.

Examples of diesel engines covered by these regulations include those that are found in construction, forestry and agricultural machines. A factsheet has been developed to assist persons and companies in determining if they are subject to the regulations or not. The factsheet is also a good first step to get a sense of the different general requirements of the regulations.
