Information:
The Electronic Control Module (ECM) provides the air/fuel ratio control. The fuel flow is controlled in order to maintain exhaust emissions. The fuel flow is also adjusted for changes in the fuel energy content. The system includes the basic components that are shown in Illustration 1.
Illustration 1 g00905946
Schematic of the air/fuel ratio control
(1) ECM in a remote panel
(2) Manifold air pressure sensor
(3) Oxygen buffer
(4) Oxygen sensor
(5) Inlet manifold temperature sensor
(6) Actuator
(7) Fuel valve
(8) Caterpillar Electronic Technician (Cat ET)
(9) Digital Diagnostic Tool (DDT) ECM (1) is the main component of the system. For the air/fuel ratio control, three inputs are provided to the ECM by sensors on the engine: inlet manifold air pressure, inlet manifold air temperature and exhaust oxygen level. The ECM uses the inputs to calculate the desired fuel flow.Manifold air pressure sensor (2) is mounted on the engine. The sensor measures the engine's inlet manifold air pressure (absolute pressure). The ECM uses the information to calculate the engine load.Oxygen buffer (3) is mounted on the engine. The buffer provides an interface between oxygen sensor (4) and the ECM. The buffer controls the sensor's heater and the supply of voltage to the sensor. The buffer also converts the sensor's output current into a signal that is sent to the ECM. The ECM converts the duty cycle into a percent of oxygen.Oxygen sensor (4) is mounted in an adapter ring on the exhaust elbow. The sensor measures the percent of oxygen in the engine's exhaust. The exhaust oxygen level is an indication of the exhaust emissions. The sensor has a heater that is used during calibration. Voltage is input to the sensor and a current signal is output by the sensor to the oxygen buffer.The ECM is programmed with a map of desired exhaust oxygen versus the inlet manifold air pressure. The map is used to adjust the percent of desired exhaust oxygen according to the calculated engine load.Inlet manifold temperature sensor (5) monitors the temperature of the air/fuel mixture after the aftercooler. The ECM compares information from the inlet manifold temperature sensor to a programmed map. The map is used to offset the percent of desired exhaust oxygen for various inlet manifold temperatures in order to maintain a constant level of NOx.For example, the desired exhaust oxygen can be increased by 0.016 percent for each 1 °C (1.8 °F) of temperature that is greater than 45 °C (113 °F). The desired exhaust oxygen can be decreased by 0.016 percent for each 1 °C (1.8 °F) of temperature less than 45 °C (113 °F). In either case, the maximum adjustment is approximately 0.7 percent.The ECM sends a command to actuator (6) in order to move fuel valve (7). The fuel valve is located between the gas pressure regulator's outlet and the carburetor's fuel inlet. The quantity of fuel that is delivered to the carburetor is determined by the
