A cogeneration system that is operated in system connection is disconnected from the system and operated independently at a power failure of the system. A power generatordriven by an engine E is connected to a system. A water-cooling devicerecovers exhaust heat of the engine E. When an operating switchis switched, to its independent operation mode for an independent operation apart from the system, the upper limit of the target rotation speed Ntgt of an electronic governoris increased over that at system connection operation, thereby the engine speed can be increased, and the maximum output point of the power generatoris increased for operation. When a power failure of the systemis detected by a power failure detecting unit, an operation mode judging unitoutputs a judgment result similar to that at the moment when the independent operation mode is instructed and increases the upper limit of the target engine speed Ntgt, and turns off a connection switchto disconnect the system connection.

Cogeneration apparatus

The purity of a refrigerant liquid can be maintained to an appropriate level without being varied corresponding to a change in the atmospheric condition and the loading state. A portion of the refrigerant liquid in an evaporator is conveyed from the evaporator to the upper end of a rectifier where it is used as a vapor/liquid contact fluid. A temperature sensor T,is provided at the upper end of the rectifier for detecting the temperature at the top of the rectifier or the temperature of the refrigerant vapor. The temperature and the purity of the refrigerant vapor are closely related to each other. The higher the temperature, the lower the purity is deteriorated. When the temperature T detected by the temperature sensor T,is higher than a reference temperature level Tref, a flow control valve V,is actuated to increase the flow of the refrigerant liquid to the rectifier. This recovers the purity of the refrigerant vapor, thus preventing declination of the purity of the refrigerant vapor in the evaporator.

Absorption type refrigerating apparatus

An absorption refrigerator is minimized in the size and the weight. A sensible heat exchanger 14 and a cooling fan 19 for cooling the sensible heat exchanger 14 are mounted front and rear opposite to each other to form a cooling unit. At one side of the fan 19, a regenerator 3 and a rectifier 6 are aligned vertically one over the other. At the other side of the fan 19, an evaporator 1 and an absorber 2 of a rectangular configuration are provided side by side. A condenser 9 is laid above the cooling unit. The cooling unit, the evaporator 1, the absorber 2, the condenser 9, the regenerator 3, the rectifier 6, and a set of pumps P1 to P4 all are installed in a main housing 20 of substantially a rectangular parallelopiped shape having a depth reduced axially of the cooling fan 19.

Absorption refrigerator

An absorption refrigerating/heating apparatus which performs in any of three modes; refrigerating, thermodynamic heating, and direct flame heating and improves the thermal efficiency during the operation of a direct flame heating mode to decrease the running cost. In the direct flame heating mode, the refrigerant and/or the absorbent is passed to the regenerator to decrease the concentration of the absorbent in the solution in the regenerator. Consequently, the temperature of the solution required for maintaining the vapor pressure in the regenerator at a desired rate can be lowered thus saving the heat needed for heating the solution.

Absorption refrigerating/heating apparatus

After a running stop command is released, a pump P2 for transferring a solution from the absorber 2 to a regenerator 3 is kept running. The transfer of the solution permits separation of the solution from a refrigerant during non-operation of the refrigerator. The solution saved in the regenerator 3 remains at as a high concentration of the absorbent as that before the end of the operation while the refrigerant is saved in an evaporator 1. This enables the refrigerator to restart its normal operation corresponding to an operation start command.

Method of stopping an absorption refrigerator

An absorption refrigerating/heating apparatus in which a refrigerant vapor generated in the evaporator (1) is absorbed to produce absorption heat by the absorbent in an absorber (2). There are first tube for chilled water in the evaporator, a second tube for cooling water in the absorber, a third tube in an indoor unit (15), and a forth tube in a sensible heat exchanger. The first tube and the second tube are respectively connected to the third tube and the fourth tube in a cooling operation, while to the fourth tube and the third tube respectively in a heating operation.

The current ignition delay angle is increased gradually until the delay angle reaches a maximum delay angle stored in a maximum delay angle storage unit when the failure of a traction control unit is detected by a failure detecting member while a switching member is set so as to select the output of a traction control mode ignition angle calculating device. A failure control mode ignition angle calculating device calculates an ignition angle on the basis of the increased delay angle and a standard ignition angle. In case failure occurs in the traction control system during traction control operation, ignition delay angle is increased gradually to reduce the running speed of the vehicle gradually regardless of the opening of the throttle valve. Accordingly, the vehicle is not subjected to shocks attributable to the change of control mode when failure occurs in the traction control system.

Automotive traction control system

A motor vehicle transmission system, for use on a motorcycle, for example, includes a sensor for detecting a direction in which a shift pedal is operated for an upshift or a downshift, a torque direction sensor for detecting a direction in which the torque is transmitted between an engine and a drive wheel, and an engine output power control assembly responsive to output signals from the sensors for temporarily increasing or reducing the output power of the engine, so that a transmission mechanism can be shifted without disengagement of a clutch.
