摘要： An engine control system is provided which calculates an optimum air/fuel ratio by minimizing the smoke produced by the engine while at the same time maximizing the engine response time for all altitudes over which the engine operates. The control system includes a microprocessor, an ambient pressure sensor, fuel injectors, and storage means. A manual adjustment is provided that allows an operator to manually adjust the air/fuel ratio within certain pre-defined limits of the optimum value.

摘要： A method for an internal combustion engine controls engine timing as a function of engine load, speed and air intake temperature to reduce engine NOx emissions and/or engine fuel consumption. The method is particularly beneficial to a large, aftercooled turbocharged engine which utilizes a cooling system having a liquid cooled, separate circuit aftercooler (SCAC) to cool the pressurized intake air. By routing the aftercooler circuit and engine coolant circuit through a common or single core radiator, the aftercooler cooling circuit temperature and associated engine air intake temperature are reduced to further reduce engine NOx emissions and/or engine fuel consumption.

摘要： A method for controlling an engine turbocharger having a wastegate control valve is provided where the turbocharger is controlled by an electronic controller which is capable of delivering a wastegate control signal to the wastegate control valve. A determination is made as to whether an engine speed falls within a predetermined speed range defined by a first predetermined speed and a second predetermined speed, where the second predetermined speed is higher than the first predetermined speed. A predetermined initializing wastegate control signal may be delivered to the wastegate control valve in response to the engine speed falling within the predetermined speed range. A determination is made as to whether an engine speed exceeds the second predetermined speed, and a determination is made as to whether an engine load falls within a predetermined load range defined by a first predetermined load and a second predetermined load, where the second predetermined load is greater than the first predetermined load. A stored control signal value is retrieved from memory associated with the electronic controller and a wastegate control signal corresponding thereto is delivered to the wastegate control valve in response to the engine speed exceeding the second predetermined speed and the engine load falling within the predetermined load range. The stored control signal value may be updated with a learned control signal value determined during certain engine operating conditions.
