In addition, when the vehicle is stopped, the engine is kept in an idle state, and the amount of fuel supplied to the engine is increased according to the amount of power consumed by the on-board equipment, increasing the exhaust energy. Supply equipment.

(Example) Next, an example of the present invention will be described in detail using the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

1 is a diesel engine that drives a vehicle, and is an insulated engine that uses ceramics as a heat insulator in the engine's cylinder liner, cylinder head, piston head, piston ring, valves, intake and exhaust ports, and other parts around the combustion chamber. It is. Since this type of adiabatic engine does not require cooling of the cylinder liner, cylinder head, etc., high-temperature exhaust gas containing a large amount of thermal energy is discharged from the exhaust pipe 11.

Note that the illustrated reference numeral 13 is a fuel tank, and 14 is an injector that injects fuel into the engine 1. Control of the fuel injection amount is issued from a controller described later.

Reference numeral 2 designates a turbocharger, which includes a turbine 21 driven by exhaust gas energy discharged from the exhaust pipe 11 and a compressor 23 directly connected to a rotating shaft 22 of the turbine 21. is driven, and the compressed air is force-fed to the engine 1 via the intake pipe 12 as supercharging air.

Reference numeral 3 denotes a rotating electric machine serving as an electric generator, and includes a rotor 31 directly connected to the rotating shaft 22 of the turbine 21 and a stator 32 having an AC winding corresponding to the rotor 31. Then, the exhaust energy from engine 1 causes turbine 2 to
1 is driven, alternating current power is output from the stator 32 of the rotating electrical machine 3. Note that when the engine 1 is at low rotation speed and high load, the rotating electric machine 3 is
is operated as an electric motor, and is configured to assist the supercharging operation of the compressor 23 and increase the output of the engine 1.

4 is a rectifier that converts AC power into DC power, and 5 is a power converter, which converts the AC output from the rotating electrical machine 3 during power generation into DC power, and makes the power suitable for charging the battery 6. be.

7 is the controller, which is composed of a microcomputer, and is equipped with a central control unit that performs arithmetic processing, various memories that store arithmetic processing procedures and control procedures, and a human/output boat.The output boat has DC power and AC power. Powerful electrical equipment such as inverters and converters are connected. Note that 71 is an inverter that converts the DC power from the battery 6 into 100cm AC power based on the commercial power source, and the controller 7 converts the injector 14 according to the consumption amount of the AC power and the power consumption of the 12V DC line. The fuel supply amount to the engine 1 is controlled by commanding the engine.

Next, the operation of this embodiment configured in this way will be explained. For example, as shown in the explanatory diagram of the inside of the car shown in FIG.
In addition to computers, facsimiles, copy machines, etc. as OA equipment, in cars equipped with electrical appliances such as air conditioners, electric refrigerators, coffee makers, etc., depending on the specifications of various equipment and products, DC 12V lines, etc.
The power cord is connected to the AC 100V line.

On the other hand, the engine 1 of the vehicle is in an idling state,
The diesel engine drives the turbine 21 through the exhaust pipe 11 to rotate the rotating electric machine 3 without reducing the amount of gas discharged unlike the gasoline engine.

Then, as the power consumption of OA equipment, home appliances, etc. increases, the controller 7 instructs the injector 14 to increase the amount of fuel supplied, which increases the exhaust gas energy and generates electricity for the rotating electric machine 3. Operation becomes active, and if the power consumption of the onboard equipment is only a few KW/H, the amount of fuel supplied only needs to increase slightly compared to when it is idling, and the power consumption can be covered by a small amount of rotating blades compared to when it is idling. .

In addition, while the vehicle is running, the engine 1 is an adiabatic engine, so the heat energy contained in the exhaust gas is large, and therefore the rotating electric machine 3 generates electricity, which is sufficient to cope with the power consumption of the onboard equipment. Sufficient power can be stored in the

(Effects of the Invention) According to the present invention, a turbocharger with a rotary cage is provided in a vehicle with an adiabatic diesel engine, and an O
Since the power consumption of A equipment and electric appliances is covered by the power generated from the rotating electrical machine that has recovered exhaust energy, there is an advantage that while the vehicle is running, the power that is generated from the rotating electrical machine that has recovered exhaust energy is sufficient to cover the power consumption. In addition, when the engine is stopped, the engine is kept in an idle state, and the amount of fuel supplied to the engine is increased in accordance with the increase in the power consumption of equipment, which increases exhaust energy, so the power generated by the rotating electrical machine is adjusted to match the power consumption. In addition, the engine speed does not change much from when it is idling, so there is an effect that the increase in engine vibration and noise is also small.
