A control box (11) for a dual-fuel internal-combustion engine (6) is actuated automatically by an oil-pressure switch (16) when activated by a manual switch (30) that directs power from a battery (29) or other engine-electrical component to a current distributor such as a 24-volt bus (49) for operating control-box components that include an under-current sensor (36) for preventing use of gaseous fuel in addition to liquid fuel under no-load and low-load conditions, an over-current sensor (39) for preventing use of gaseous fuel in addition to liquid fuel under excessive-load conditions, an intake-air sensor (17) for preventing use of gaseous fuel with liquid fuel when there is inadequate supply of air, a liquid-fuel-supply sensor (22) for preventing use of gaseous fuel with liquid fuel when there is inadequate supply of liquid fuel, and an exhaust-gas-temperature monitor (23) for shutting down dual-fuel mode when exhaust heat is excessive. Red LED lights (41, 42, 43, 44, 45, 46) warn of system faults. The engine does not shut down when one or more parameters fail. Professional resetting is required in order to alert operators of possible dangers when the system has been shut down from excessive exhaust-gas heat.
A dual-fuel-engine monitoring-and-control system comprising:
A method comprising the following steps for adapting an internal-combustion engine to utilize a high proportion of gaseous fuel in proportion to liquid fuel without operative damage to the internal-combustion engine or to an engine system powered by the internal-combustion engine:
