Abstract

A fuel injection timing management system for a dual fuel engine is configured to determine a first diesel injection timing corresponding to a first mode of operation of the engine system and a second diesel injection timing corresponding to a second mode of operation. The system may further determine a direction of change in a mode of operation of the engine system, and selectively perform a change in the diesel injection timing from the first diesel injection timing to the second diesel injection timing at a first rate of transition or a second rate of transition, based on the direction of change in a mode of operation of the engine system.

First claim

What is claimed is:

1. A diesel fuel injection timing management system for a dual fuel engine system having a diesel-gas mode and a diesel only mode, the system comprising:
a diesel fuel mass flow rate sensor configured to generate a diesel fuel mass flow rate signal indicative of a diesel fuel mass flow rate;
a gaseous fuel mass flow rate sensor configured to generate a gaseous fuel mass flow rate signal indicative of a gaseous fuel mass flow rate;
a mode selector switch con…
