Abstract

The present invention provides an engine control method, which comprises: receiving an indication of the pedal position; pre-processing the indication of the pedal position to determine whether the received indication of the pedal position corresponds to the antisurge mode activation condition; in response to the received indication of the pedal position corresponding to the antisurge mode activation condition, using the boost pressure and the engine speed to look up the static control parameter lookup table to select a control parameter indicating an air flow requirement; and sending the selected control parameter to the ECU so as to control the engine using the air flow requirement indicated by said control parameter.

Description

technical field [0001] The present invention relates generally to engine control techniques and, more particularly, to methods and systems for providing improved engine control. Background technique [0002] Gasoline or natural gas engines have been the primary mode of propulsion for many types of vehicles for many years. Therefore, aiming to improve the performance of gasoline or natural gas engines in the areas of power and efficiency is a desirable goal. A turbocharger is an example of improving the performance of a gasoline or natural gas engine. A turbocharger can be thought of as a type of gas compressor used to increase the mass of air entering the engine to produce more engine power. Therefore, a turbocharger is an air compressor driven by the exhaust gas generated by the operation of the internal combustion engine, which can increase the air flow into the internal combustion engine or boiler, thereby improving the efficiency of the machine. Commonly used in autom...
