ＨＣ型エンジン。 The intake valve and exhaust valve are V with respect to the combustion chamber.
In a DOHC type engine in which the intake valve and the exhaust valve are driven to open and close by their respective camshafts, a head bolt fastening valve is installed at a portion of the camshaft located above the axis of the head bolt that fastens the cylinder head to the cylinder block. A through-hole is formed with a margin for inserting the tool, and the relationship between the tool insertion range above the head bolt and the through-hole is such that one camshaft overlaps, and the other camshaft overlaps the notch at the end of the through-hole and the insertion range. A DO characterized by being configured as follows.
HC type engine.
