摘要： The purpose of the present invention is to prevent clogging of a filter without incurring an increase in cost or the complexity of a configuration. Further, an intake unit properly takes in a fuel without taking in the air even when there is a lesser amount of the fuel in a fuel tank. A joining and discharging unit (7) for joining and discharging the fuel is disposed to a site between the fuel tank (2) and the filter (10) in a fuel supply route (4). A first fuel return route (12) returns the fuel of an engine (3) to the joining and discharging unit (7). A second fuel return route (13) returns the fuel discharged from the joining and discharging unit (7) to the fuel tank (2).

摘要： PURPOSE: An waste heat recycling type of a gas engine system is provided to evaporate LNG injected into an engine using high-temperature waste gas when the engine combusts. CONSTITUTION: An waste heat recycling type of a gas engine system comprises a gas engine(27), an waste heat regenerator and a heat exchanger(33). The gas engine is operated by LNG supplied from a LNG supply line. The waste heat regenerator comprises a working fluid circulation line(41), a pump(31) and a waste heat recovery unit. The working fluid cycle line forms one closed circuit. The pump installed to the working fluid cycle line circulates the working fluids. The waste heat recovery units increase the temperature of the working fluids by heat exchanging between the working fluid and the combustion gas from the gas engine. The heat exchanger keeps LNG injected into the gas engine in an evaporated state within a constant temperature range by heat exchanging between the working fluid heated by the waste heat regenerator and the LNG injected into the gas engine through the LNG supply line.
