News from Cummins reports that it completes air-fuel ratio control system recently. Building on current engine control capability, Cummins has developed a proprietary air-fuel ratio control system that employs a dithering control algorithm with dual-loop feedback for rich-burn engines. With 200 tests and over 4,000 test hours on the engine and emissions control system, Cummins engineers have developed a new reliable and durable air-fuel ratio controller and catalyst combination that is integrated with today’s proven engine. Cummins tests validate the air-fuel ratio control system’s capability to compensate for environmental variations such as humidity, catalyst inlet temperature, fuel quality and air intrusion into the exhaust stream.

Cummins Inc., a global power leader, is a corporation of complementary business units that design, manufacture, distribute and service engines and related technologies, including fuel systems, controls, air handling, filtration, emission solutions and electrical power generation systems.
