1. An industrial combustion liquid propane-fueled engine, comprising:
- at least one intake port;
a fuel injection system comprising at least one fuel injector configured to inject liquid propane into the at least one intake port; and
an engine controller comprising a governor device configured to maintain the speed of the engine at or near a predetermined value, wherein the engine controller controls the at least one fuel injector to control a rate and a timing of fuel injection into the at least one intake port based on at least one of;
the predetermined value as selected by a user, the predetermined value as selected by the engine controller, and the predetermined value as sensed by a powertrain control module and communicated to and controlled by the engine controller.

15. A method for starting an industrial internal combustion liquid propane-fueled engine, comprising:
-
providing an industrial internal combustion liquid propane-fueled engine, comprising; at least one intake port, a fuel injection system comprising at least one fuel injector configured to inject liquid propane into the at least one intake port, an engine controller comprising a governor device configured to maintain the speed of the engine at or near a predetermined value, and a starter; providing a fuel cell configured to hold the liquid propane, wherein the fuel cell comprises a fuel pump capable of both transferring the liquid propane to the fuel injection system and removing a propane vapor from the fuel injection system; operating the fuel pump in a first configuration wherein the fuel pump removes propane vapor from the fuel injection system; operating the fuel pump in a second configuration wherein the fuel pump transfers liquid propane to the fuel injection system; activating the fuel injection system to cause the at least one fuel injector to inject liquid propane into the at least one intake port; and activating the starter. - View Dependent Claims (16, 17, 18, 19, 20)
