The KOHLER® EFI (Electronic
Fuel Injection) engine features closed loop technology. The Kohler EFI system has been engineered for consistent easy starts, lower fuel consumption, improved load pickup and optimal performance. The onboard fuel module, 4-wire oxygen sensor and unique location of the fuel injectors complete the Kohler's closed loop system.
Benefits of a Closed Loop EFI System
Best in class fuel economy - Calibration is always being optimized for weather, engine condition, fuel supply and fuel type.
Best in class durability and repeatability-
Always delivering the correct amount of fuel.
4-Wire Oxygen Sensor
The Oxygen sensor is a critical sensor in the operation of the Kohler closed loop EFI system. The O² sensor provides information to the ECU on the amount a oxygen content in the exhaust and ECU adjust the fuel mixture to achieve the right amount of fuel when it is needed.
4 wire O2 sensor gives most robust sensing of any feedback system
provides its own ground path through wire rather muffler
has a heater for faster response and fuel adjustment accuracy
optimizes fuel delivery over the life of the engine
compensates for air cleaner changes and engine changes
