Use direct couple or belt drive to a shaft driven
refrigeration pump. Every refrigerated truck, trailer and
train car use this method. A common brand is Thermo-King. A
diesel engine is connected to a refrigeration pump. Another
example is the air conditioner in your car; it uses a belt
driven refrigeration pump.

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.
