Equipment at the EECL
back to Facility and Capabilities index

Since 1992, the EECL has created a legacy of developing products which improve engine efficiency and reduce harmful emissions from engines as small as 1 hp to as large as 2500 hp. Our work is primarily focused on advancing ignition system (laser, micropilot, pre-combustion chamber) and after-treatment (SCR, 3-way catalysts, NSCR, oxidation catalysts).
