Patent ID: 8312865

Claim:
A kit for reducing exhaust emissions from an existing EMD 567/645 two-cycle diesel engine by retrofitting the engine from mechanical fuel injection to electronic fuel injection, the kit comprising: a plurality of electronic unit fuel injectors for installation in the engine at locations where preexisting mechanical fuel injectors were removed from the engine; an electronic control module to be electrically connected to the electronic unit fuel injectors for delivering electronic injection signals to the electronic unit fuel injectors; connectors for connecting fuel lines of the electronic unit fuel injectors to a preexisting fuel manifold of the engine from which the mechanical fuel injectors were removed; an angle-drive-replacement timing gear unit adapted for attachment on the engine at a location where a preexisting governor angle drive was removed from the engine and having a timing gear driven like the governor angle drive by the engine and a sensor for sensing angular position and speed of the timing gear; wherein the sensor of the timing gear unit is connectable to the electronic control module and the electronic control module is programmed to utilize a signal from the sensor of the timing gear unit to indicate an angular position to be used in timing fuel injection by the electronic unit fuel injectors; and wherein the electronic control module is programmed for operating the electronic unit fuel injectors to improve emissions performance of the EMD 567/645 two cycle diesel engine and meet EPA locomotive Tier 2 emission standards.
