Abstract: This disclosure provides a system and method that eliminates the need for manually calibrating or adjusting a dual fuel internal combustion engine to compensate for variations in composition of a gaseous fuel or other variations, such as ambient or site conditions. The system and method functions by determining an engine load, determining an advantageous gaseous fuel substitution rate from the engine load and speed in addition to an actual gaseous fuel substitution rate, modifying the advantageous gaseous fuel substitution rate by a minimum liquid fuel flow rate, engine protection parameters, and oxidation catalyst protection parameters, and then determining an error term in response to the modified advantageous gaseous fuel substitution rate and the actual gaseous fuel substitution rate. The error term is used to adjust a gaseous fuel control valve.
Abstract translation: 本公开提供了一种系统和方法，其消除了手动校准或调节双燃料内燃机以补偿气体燃料的组成变化或其它变化（例如环境或现场条件）的需要。 该系统和方法通过确定发动机负载，除了实际气体燃料替代速率之外，确定来自发动机负载和速度的有利的气体燃料替代速率，通过最小液体燃料流量来改变有利的气体燃料替代速率，发动机 保护参数和氧化催化剂保护参数，然后响应于改进的有利气体燃料替代速率和实际气体燃料替代速率来确定误差项。 误差项用于调节气体燃料控制阀。
