IPC: F02B37/10
Filed: 2002-06-07
Abstract: <P>PROBLEM TO BE SOLVED: To autonomously control the rotational speed of a turbocharger having a burner of a reciprocal internal combustion engine.  <P>SOLUTION: The turbocharger 2 has a compressor 4 and a turbine 5. Compressed air from the compressor 4 is fed to an engine 10 and a burner 1. The burner 1 generates combustion gas and drives the turbine 5 together with exhaust emission from the engine. A fuel nozzle 21 of the burner 1 is a two-fluid type nozzle with external compressed air of predetermined pressure and liquid fuel fed thereto, and the flow rate is autonomously controlled, for example, the fuel flow rate is reduced when the combustion gas pressure in the burner is increased. Any complicated and expensive governor is unnecessary. An external compressed air feed means 23 is connected to the compressor 4, and compressed air is charged to the compressor of the turbocharger as necessary. Therefore, the rotational speed of the turbocharger is controlled by giving the drive energy to the turbocharger during the start of the engine with less exhaust energy, increasing the volume itself of the compressed air fed by the turbocharger, and rapidly demonstrating the performance of the burner.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-06-26
Abstract: <P>PROBLEM TO BE SOLVED: To minimize refrigerant leakage with an inexpensive means.  <P>SOLUTION: Pressure of back pressure chambers 71g and 71h is reduced by suction pressure of a compressor to open the refrigerant inlet side and refrigerant outlet side of an evaporator, and, in stopping the compressor, a first coil spring 76 and a second coil spring 77 mechanically close the refrigerant inlet side and refrigerant outlet side of the evaporator 40. Thus, the refrigerant leakage can be minimized by the inexpensive means. The refrigerant inlet side and refrigerant outlet side of the evaporator are closed during the stopping of the compressor. Therefore, even if refrigerant leakage occurs when an ignition switch is broken over a long time such as in night parking and power is not supplied to a refrigerant leakage sensor and an ECU, a lot of refrigerants can be prevented from filling a room.  <P>COPYRIGHT: (C)2004,JPO
