Title:
CONTROL MECHANISM FOR SELECTIVELY OPERATING INTERNAL COMBUSTION ENGINE USING TWO KINDS OF FUELS
Document Type and Number:
Japanese Patent JPS58144645
Kind Code:
A
Abstract:
Disclosed herein is an apparatus which is adapted for controlling operation of an internal combustion engine operable selectively which is on gaseous fuel or liquid fuel, and which comprises a gaseous fuel supply line extending between the engine and a source of gaseous fuel, a liquid fuel supply line extending between the engine and a source of liquid fuel, and a control for controlling supply to the engine of the gaseous fuel and the liquid fuel, which control includes an operator controlled fuel selector switch movable between a gaseous fuel position and a liquid fuel position, which control is operable following prior engine operation with gaseous fuel and in response to movement of the fuel selector switch from the gaseous fuel position to the liquid fuel position for permitting liquid fuel flow through the liquid fuel supply line, for permitting continued gaseous fuel flow through the gaseous fuel supply line until initiation of liquid fuel combustion, and thereafter preventing further gaseous fuel flow through the gaseous fuel supply until repositioning of the fuel selector switch to the gaseous fuel position, and which control is also operable following prior engine operation with liquid fuel and in response to movement of the fuel selector switch from the liquid fuel position to the gaseous fuel position for preventing further liquid fuel flow through the liquid fuel supply line, for preventing gaseous fuel flow through the gaseous fuel supply line until termination of liquid fuel combustion, and for thereafter permitting gaseous fuel flow through the gaseous fuel supply line until repositioning of the fuel selector switch to the liquid fuel position.
