Claims (1)
回動軸を中心に閉弁方向に常時附勢された排気ブ
レーキバルブを、暖機バルブとして使用するよう
にした車両の暖機装置において、前記排気ブレー
キバルブの回動軸を前記排気管の軸心に直交する
ように配設すると共に、前記排気ブレーキバルブ
のうち前記排気ブレーキバルブの回動中心以外の
箇所であつてかつ前記回動中心に対して排気ガス

特徴とする車両の暖機装置。 In the warm-up device for a vehicle, the exhaust brake valve is used as a warm-up valve, and the exhaust brake valve is always energized in the valve-closing direction around the rotation axis while being inclined with respect to the exhaust pipe of the engine. The rotational axis of the exhaust brake valve is disposed so as to be orthogonal to the axis of the exhaust pipe, and the rotational axis of the exhaust brake valve is located at a location other than the rotational center of the exhaust brake valve and located at the rotational center of the exhaust brake valve. On the other hand, a vehicle warm-up device is characterized in that a communication hole or a notch is provided in a portion on the upstream side of exhaust gas.
