EPA Contract Number: 68D98154
Title: Reduced NOx/Hydrocarbon Emissions via Oxygen Enriched Lean Burn Engines
Investigators: Nemser, Stuart
Small Business: Compact Membrane Systems Inc.
EPA Contact: Manager, SBIR Program
Phase: II
Project Period: September 1, 1999 through September 1, 2000
Project Amount: $225,000
RFA: Small Business Innovation Research (SBIR) - Phase II (1998)
Research Category: Air Quality and Air Toxics , SBIR - Air

Description:

Lean burn engines are a promising technique to reduce emissions while simultaneously increasing fuel efficiency. Lean air to fuel ratios (AFR) improve HC/CO oxidation while cooler temperatures reduce NOx formation. Compact Membrane Systems, Inc. (CMS) has shown that the use of oxygen enriched air (OEA) supplied by membrane modules is an excellent method to extend the lean burn limit in spark ignition engines. Successes in Phase I included:

In Phase II, CMS will customize and improve membrane fabrication for lean burn applications; test and analyze membrane system on a lean burn engine; test durability on membrane modules; and design a prototype for commercialization at the conclusion of the Phase II program.
