Gas feed system for a gas-fired diesel engine
First Claim
1. A gas feed system of a gas-fired diesel engine, said system comprising:
- a high-pressure gas compressing apparatus for compressing gas to a high pressure, said high-pressure gas compressing apparatus disposed in a passageway defined in the system between a source of gas and an intake of the diesel engine; and
a low-pressure gas compressing apparatus for compressing gas to a low pressure that is lower than said high pressure, said low-pressure gas compressing apparatus disposed in a passageway defined in the system between a source of gas and an intake of the diesel engine.

Abstract
An improved gas feed system for a gas fired diesel engine is disclosed, in which boil-off gas evaporated from liquefied gas is fed to the diesel engine. The improvements reside in that between the diesel engine and a liquefied gas tank for storing a gaseous fuel is provided a liquefied gas adding apparatus for adding liquefied gas into the boil-off gas, and in the provision of a passageway through which high-pressure gas passes pressurized by a high-pressure compressing apparatus which compresses the boil-off gas or a mixture of the boil-off gas and the liquefied gas and the provision of a passageway through which low-pressure gas passes pressurized by a low-pressure compressing apparatus.

2. A gas feed system of a gas-fired diesel engine, said system comprising:
-
a liquefied gas storing means for storing liquefied gas and for generating boil-off gas from the liquefied gas; a liquefied gas adding means operatively connected in the system to said liquefied gas storing means for adding liquefied gas to the boil-off gas generated in said liquefied gas storing means to produce a mixture of the boil-off gas and the liquefied gas; a high-pressure gas compressing apparatus for compressing the boil-off gas generated in said liquefied gas storing means or the mixture produced by said liquefied gas adding means to a high pressure, said high-pressure gas compressing apparatus disposed in a passageway defined in the system between said liquefied gas storing means and an intake of the diesel engine; and a low-pressure gas compressing apparatus for compressing gas to a low pressure that is lower than said high pressure, said low-pressure gas compressing apparatus disposed in a passageway defined in the system between said liquefied gas storing means and an intake of the diesel engine.
