TAKING CONTROL OF GAS ENGINE ISSUES: Retrofit with new air/fuel ratio control valves helps California wastewater plant station meet emissions goals

摘要

In an effort to gain maximum engine performance and stay within the local exhaust emission limits over a wide range of engine load and ambient conditions, operators at the County Sanitation Districts of Los Angeles County's Joint Water Pollution Control Plant wastewater treatment plant near downtown Los Angeles have installed Continental Controls Corp. ECV5 air/fuel ratio control valves on five gas-fueled engines in an effluent pump station. The engines were installed during a facility upgrade to comply with an EPA-mandated expansion of the facility's secondary treatment process to increase flow.
