Continental Controls Corp. has introduced an emissions control system for powerful natural gas engines up to 4000 hp. This system combines components like the ECV5 emissions control valve, a Zirconium Oxide O2 sensor, a three-way catalytic converter, and a monitoring unit (TCA). The ECV5 regulates fuel injection pressure based on exhaust oxygen levels, achieving optimal air-fuel ratio and catalytic converter performance. The technology meets stringent emissions standards, like those in Southern California, and contributes to cleaner engine operation.
