초록 ▼

A turbocharged or supercharged internal combustion motive system for utilization of gaseous fuel stored as a liquid wherein the liquefied gaseous fuel is vaporized and warmed at least partially with heat removed from the compressed intake combustion air in the turbocharger or supercharger aftercooler. In a preferred embodiment, the compressed intake combustion air is first cooled in an aftercooler against an ambiently cooled coolant and is subsequently cooled in further aftercooler heat exchange passages against an intermediate coolant which transfers heat removed from the compressed intake combustion air to the liquefied gaseous fuel. Embodiments are disclosed wherein the saturated liquefied gaseous fuel is first subcooled and then pumped to pressures high enough for direct combustion chamber injection and another embodiment discloses vaporization of the saturated liquefied gaseous fuel with compression of the vaporized gas in a compression-type injection system or by low pressure carburetion into the internal combustion engine.

대표청구항 ▼

In an internal combustion engine fueled with a fuel gas vaporized from a liquefied gaseous fuel and having means for compressing the combustion intake air and an aftercooler for cooling the compressed combustion intake air against an ambient coolant source, and additional means for effecting heat exchange between the liquefied gaseous fuel and compressed combustion intake air whereby heat is removed from the compressed combustion intake air and said heat is transferred to the liquefied gaseous fuel, the improvement wherein said heat exchange means for effecting heat exchange between the liquefied gaseous fuel and the compressed combustion intake air comprises a cold fuel heat exchanger for indirect heat exchange between the liquefied gaseous fuel and a warmed intermediate circulating coolant wherein heat transferred from the warmed intermediate circulating coolant to the liquefied gaseous fuel lowers the temperature of the warmed intermediate circulating coolant to produce a chilled intermediate circulating coolant and warms the liquefied gaseous fuel to produce a warmed fuel; means for conducting the liquefied gaseous fuel to the cold fuel heat exchanger; means for conducting the warmed fuel to the combustion chambers of the internal combustion engine; means for conducting the chilled intermediate circulating coolant from the cold fuel heat exchanger to the intake air compressor aftercooler wherein the chilled intermediate circulating coolant is indirectly heat exchanged against the compressed combustion intake air to produce a chilled compressed combustion intake air charge and a warmed intermediate circulating coolant; and means for conducting the warmed intermediate circulating coolant back to the cold fuel heat exchanger.
