A DUAL FUEL SUPPLY SYSTEM FOR AN INDIRECT-INJECTION SYSTEM OF A DIESEL ENGINE

摘要

The present invention relates to fuel systems for diesel engines. In particular, the invention relates to a dual fuel supply system (10) for a diesel engine having an indirect-injection system (12). The invention extends to a diesel engine incorporating the dual fuel supply system (10) and to a vehicle that incorporates a diesel engine having the dual fuel supply system (10). The dual-fuel supply system (10) includes a mixed fuel supply system (17) that includes a first stage (14) having a diesel tank (42) and LPG tank (44), and as second stage (16) to supply the fuel mixture to the injection system (12). The dual-fuel supply system (10) also includes diesel supply system (80) for delivering diesel to the injection system (12). Moreover, the dual fuel system (10) is configured to permit selective change over between the diesel supply system (80) and the mixed fuel system (17) to supply the injection system (12) selectively with either diesel or liquid fuel mixture respectively.
