Abstract
An improved high viscosity fuel injection pressure reduction system and method is disclosed for use in an internal combustion engine. The system may include a first fuel line and a second fuel line. The first fuel line may be configured to be coupled upstream of a combustion chamber of the engine when the engine is operated with the first fuel and to provide a first pressurized volume when installed. Likewise, the second fuel line may be configured to be coupled upstream of the combustion chamber of the engine when the engine is operated with the second fuel and to provide a second pressurized volume when installed. The first and second volumes of the fuel lines may provide peak injection pressures lower than a desired pressure when the engine is operated with the first and second fuels, respectively.
