<P>PROBLEM TO BE SOLVED: To improve exhaust characteristics while suppressing deterioration in fuel distribution capability to cylinders and follow-up capability to a change in fuel amount, in a dual fuel engine that can burn a mixture of light gas oil and a compressed natural gas (CNG). <P>SOLUTION: A fuel feed system for the dual fuel engine includes: a light gas oil feeding device (10) for directly feeding the light gas oil into the cylinder of an internal combustion engine; a first CNG feeding device (21) for feeding the compressed natural gas on the upstream side relative to a compressor of a supercharger in an intake air passage of the internal combustion engine; a second CNG feeding device (22) for feeding the compressed natural gas on the downstream side relative to the compressor of the supercharger in the intake air passage of the internal combustion engine or into the cylinder of the internal combustion engine; and a switching device (24) for switching a device for feeding the compressed natural gas to the internal combustion engine between the first CNG feeding device and the second CNG feeding device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
