    • In an engine, an oil level sensor (47) provided in a bottom part of an oil pan (15) storing engine oil so as to stand vertically upright is placed between a mutually parallel pair of balancer shafts (27, 28) housed in a balancer housing (21) provided between a lower face of a cylinder block and the oil pan (15). This not only enables the oil level sensor (47) to be placed compactly by utilizing effectively dead space formed between the pair of balancer shafts (27, 28), but also enables agitation of engine oil to be suppressed by the pair of balancer shafts (27, 28) and any degradation in detection precision due to engine oil splashing over the oil level sensor (47) to be prevented.
    • 在发动机中,设置在油盘(15)的底部的油位传感器(47)设置在彼此平行的一对平衡轴(27,28)之间,平衡轴 设置在气缸体的下表面和油盘(15)之间的平衡器壳体(21)。 这不仅能够通过有效地利用一对平衡轴(27,28)之间形成的空隙来紧凑地设置油位传感器(47),而且还能够使由一对平衡轴(6)抑制的发动机油的搅拌 并且由于发动机油溅射在油位传感器(47)上而导致的检测精度的任何劣化被防止。
