OIL JET AND ENGINE ASSEMBLED THE OIL JET

摘要

PURPOSE: An oil jet and an engine employing the same are provided to reduce frictional resistance through fast warm-up of engine oil sprayed to a piston because the oil jet is press-fitted to a bulkhead to pass through a breath hole. CONSTITUTION: An engine comprises a cylinder block(10) and an oil jet(1). The cylinder block has a hole bored from a bulkhead(11) to a breath hole(12). The oil jet is press-fitted to the hole and sprays oil, which is provided from a crank bore, upward from the underside of the cylinder at a fixed angle.
