High viscosity fuel injection pressure reduction system and method
First Claim
1. An engine system, comprising:
- an internal combustion engine configured to operate by combustion of a first fuel or a second fuel;
a first fuel line 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; and
a second fuel line 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;
wherein the first pressurized volume is less than the second pressurized volume and wherein a size of the first pressurized volume is associated with a kinematic viscosity of the first fuel and a size of the second pressurized volume is associated with a kinematic viscosity of the second fuel.

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.
