To optimize arrangement of a lubrication pump and a cooling pump.SOLUTION: A motor vehicle has: two front wheels; two rear wheels; an internal combustion engine 5 including multiple cylinders 18 in each of which a piston slides, a drive shaft connected to the pistons, multiple intake valves and exhaust valves operated by cam shafts 23, 26; and a cylinder head 21 in which the cam shafts 23, 26 are disposed; at least one lubrication pump 60 configured to circulate a lubrication oil; and at least one cooling pump 63 configured to circulate a coolant. The cam shaft 23 protrudes in an axial direction on at least one side of the cylinder head 21. The lubrication pump 60 is provided coaxially with the cam shaft 23 and directly connected to the cam shaft 23 so as to be rotated by the cam shaft 23.SELECTED DRAWING: Figure 28

    【課題】潤滑ポンプおよび冷却ポンプの配置を最適化すること。【解決手段】2つの前輪と、2つのの後輪と、内燃エンジン5であって、内部で各ピストンが摺動する複数のシリンダ18と、ピストンに接続された駆動シャフトと、各カムシャフト23、26によって作動される複数の吸気バルブおよび排気バルブと、カムシャフト23、26が配置されるシリンダヘッド21と、を備える、内燃エンジン5と、潤滑油を循環させるように構成された少なくとも1つの潤滑ポンプ60と、冷却液を循環させるように構成された少なくとも1つの冷却ポンプ63と、を有する自動車。シリンダヘッド21の少なくとも一方側には、カムシャフト23が軸方向に突出しており、潤滑ポンプ60は、カムシャフト23と同軸上に設けられ、カムシャフト23によって回転させられるようにカムシャフト23に直接接続されている。【選択図】図28
