Abstract

Engine control unit (ECU) will be described. In which each parameter of the machine's operating parameters The engine will be detected as follows: Engine rate (60) Throttle position (62), manifold manifold pressure (MAP) (64), gas pressure (66), gas temperature. (68) Battery voltage (70) Boost valve feedback (BPCU) Each of these parameters is provided. As an input in the form of an electrical signal to the ECU's regulator (20) for controlling the operation of an engine (10), a gas-fired internal combustion regulator (20) of E. The CU provides a known engine speed (60) and the position of the throttle (62). To calculate the percentage of full load (PEL) for an engine, the PEL is a metering value that No load or torque units are produced by or required from the engine, the calculated PFL (78) can be applied by the ECU's regulator (20) to calculate the injection time on the injector (IOT) (80. ) For each gas injection in the gas delivery system For a typical engine (10), the PFL (78) value is used in conjunction with the engine speed (60) to calculate the required manifold absolute pressure 9MAP) (82), and then the calculated value may be taken. The required MAP (82) is used together with the PFL (78) to calculate the percentage of the value. Allowable load (PAL) (84) The PAL (84) value is then used by the ECU's regulator (20) to calculate the IOT (80) and spark conductivity (88) for the engine by Using a gas injector and accurate IOT calculations, the ECU (20) can control the exact amount of gas that is received. Injection into each cylinder To accomplish Optimal engine performance under the range that Full range of load and engine speed:

1. Regulation of operation control of gas-fired internal combustion engines Which this engine There will be a gas injection for the injection of gas into In each cylinder This methodology consists of steps of Detecting the position of the throttle in the current time of the engine, calculating the percentage of full load for the engine. It is based on the current position of the throttle, such time and the INGECTOR ON TIME calculation for each cylinder on the basis of a percentage of the dozen tag values:
