Exhaust Emissions Testing
Comprehensive Emissions Testing for Engines & Equipment
Excel Engineering provides a full suite of exhaust emissions testing services to ensure your products meet all applicable EPA Part 1065 and CARB regulations. Our advanced facilities are equipped to measure regulated criteria pollutants, greenhouse gases (GHG), and particulate matter (PM) for a wide range of vehicles and equipment.
Exhaust Emissions Testing:
Our test cells are fully compliant with EPA Part 1065 and CARB guidelines. They are equipped with advanced analyzers to provide precise, repeatable results for your emissions certification and development programs.
Our Capabilities Include:
- Gaseous pollutants – We conduct direct gaseous emissions sampling for THC (total hydrocarbons), NMHC (non-methane hydrocarbons), NOX (nitrogen oxides), and CO (carbon monoxide).
- Greenhouse gases – Our analyzers measure GHG (greenhouse gas) emissions, including CO2 (carbon dioxide), CH4 (methane), and N2O (nitrous oxide).
- Particulate matter (PM) – We use a Sierra Instruments BG3 with heated sample lines, which is fully capable of transient cycle emissions testing for particulate matter.
- Testing procedures & specifications – We can perform testing in accordance with On-Highway Motorcycle Procedures (40 CFR §86.410-2006) and California ARB Title 13, CCR, §1976 guidelines.
