本考案は、車両殊に自動車用制御エネルギーの
回収装置に関するもので、以下その実施例を図面
により説明する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control energy recovery device for vehicles, particularly automobiles, and embodiments thereof will be described below with reference to the drawings.
図において、Ｅはエンジン（この例ではデイー

吸気通路１１を開閉するバルブ、２０は排気管２
１を開閉するバルブである。３はエアタンクで、
その一方は、バルブ３０を介して排気管２１へ、
また、他方は、弁圧弁３１、バルブ３２を介して
吸気通路１１に連通している。３３はエアタンク
３の安全弁である。 In the figure, E is an engine (diesel engine in this example), 1 is an intake manifold, 2 is an exhaust manifold, 10 is a valve that opens and closes the intake passage 11 to the intake manifold 1, and 20 is an exhaust pipe 2.
This is a valve that opens and closes 1. 3 is an air tank,
One of them is connected to the exhaust pipe 21 via the valve 30,
Moreover, the other side communicates with the intake passage 11 via a valve pressure valve 31 and a valve 32. 33 is a safety valve for the air tank 3.
車両の走行時、エンジンブレーキ（排気ブレー

足を離し、排気ブレーキ操作装置（図示せず）を
ONとする（逆の順序でも可）。 When operating the engine brake (exhaust brake) while the vehicle is running, take your foot off the accelerator pedal and turn on the exhaust brake operating device (not shown).
Turn ON (reverse order is also possible).

ーとして作動し、エアタンク３には圧縮空気が蓄
えられる。これにより強力なエンジンブレーキが
得られる。 Generally, when you take your foot off the accelerator pedal,
The action of the centrifugal governor returns the injection pump rack to the zero injection amount position, cuts off the fuel, and closes the valve 20 (even if the exhaust brake operating device is turned on, if the accelerator pedal is depressed, Valve 20 is typically configured not to close). At the same time, the valve 30 is opened, the valve 32 is closed, and the valve 10 is opened (for example, a combination of an electromagnetic valve and an electric circuit), so the engine E operates as a compressor, and the air tank 3 is filled with compressed air. is stored. This provides powerful engine braking.

の圧力が規定値以下例えば１Kg／cm2となつたとき
には、バルブ１０が開、バルブ３２が閉となるよ
う構成しておけば、エンジンの運転は正常に保た

エアタンクの圧力が規定値以下になつたとき、こ
れを検知して、バルブ１０と３２の作動用電磁バ
ルブ回路をON、又はOFFするような回路を設け
ることにより容易に行ないうるものである。 When the accelerator pedal is pressed in this state, the valve 20 automatically opens. That is, fuel is supplied to the engine and engine braking is released. When the valve 20 is opened, the valve 30 is closed, the valve 10 is closed, and the valve 32 is opened, and the air tank 3 is closed.
The compressed air stored in the intake manifold 1 is maintained at a constant pressure by the valve pressure valve 31, is supplied into the intake manifold 1, and is recovered as driving force. Since the conditions for performing this recovery operation include that the accelerator pedal is depressed, it is necessary to configure this in combination with the operation of the valve. If the valve 10 is opened and the valve 32 is closed when the pressure inside the air tank 3 falls below a specified value, for example, 1 kg/cm 2 , the engine can maintain normal operation. The action of the valves 10 and 32 is, for example,
This can be easily done by providing a circuit that detects when the pressure of the air tank falls below a specified value and turns on or off the electromagnetic valve circuit for operating the valves 10 and 32.
本考案は以上のように構成したので、車両の制
