A POWER UNIT FOR A VECHILE, SUCH AS AN AUTOMOBILE, INCLUDES AN INTERNAL COMBUSTION ENGINE (1) AS A PRIME MOVER FOR THE VECHILE, A GENERATOR (3), AND A STIRLING ENGINE (4) FOR DRIVING THE GENERATOR (3). THE STIRLING ENGINE (4) USES THE EXHAUST GAS DISCHARGED BY THE INTERNAL COMBUSTION ENGINE (1) AS A HIGH-TEMPERATURE HEAT SOURCE. POWER GENERATED BY THE GENERATOR (3) IS SUPPLIED TO AN ELECTRIC MOTOR (2) FOR DRIVING AUXILIARY MACHINES (7), (8) AND (9), AND TO BATTERY (5) FOR SUPPLYING POWER TO THE ELECTRIC MOTOR (2). THE ENGINE SPEED OF THE STIRLING ENGINE (4) IS CONTROLLED THROUGH THE CONTROL OF THE LOAD ON THE GENERATOR (3) BY A FIELD REGULATOR (15). AN OPTIUM ENGINE SPEED OF THE STIRLING ENGINE (4) IS DETERMINED SUCH THAT THE BRAKE HORSEPOWER OF THE STIRLING ENGINE (4) INCREASES TO A MAXIMUN OR SUBSTANTIALLY MAXIMUN BRAKE HORSEPOWER. THE FUEL CONSUMPTION OF THE INTERNAL COMBUSTION ENGINE (1) AS THE PRIME MOVER THAT PRODUCES WASTE HEAT AS A HIGH-TEMPERATURE HEAT SOURCE FOR THE STIRLING ENGINE (4) IS REDUCED, AND THE AUXILIARY MACHINES ARE DRIVEN SO AS TO FULLY EXERCISE THEIR FUNCTIONS EVEN IN A STATE WHERE THE BRAKE HORSEPOWER OF THE STIRLING ENGINE (4) IS LOW. |
