摘要： A body of an oil jet including: an oil supply port which opens into an oil passage in a cylinder block of an internal combustion engine; a cylinder one end of which is communicated with the oil supply port and the other end of which is closed; and an oil injection port which opens on a side surface of the cylinder. A piston valve is accommodated in the cylinder. The piston valve forms in the cylinder a differential pressure room which is a closed compartment. Moreover, an orifice which makes the differential pressure room being communicated with a side of the oil supply port is formed in the piston valve. The piston valve is biased toward a position at which the oil injection port is closed by a spring. Furthermore, a leak hole which allows oil to be leaked outside of the body from the differential pressure room is formed in the body.

摘要： An object of this invention is to suppress the occurrence of pre-ignition by appropriately controlling a wall surface temperature of a combustion chamber based on a target temperature region in which the frequency with which pre-ignition occurs is reflected, without causing pre-ignition to actually occur.An ECU 50 acquires a wall surface temperature of a combustion chamber 14 or an engine water temperature or the like that correlates therewith as a wall temperature parameter. The ECU 50 is equipped with data for a pre-ignition suppression temperature region that is a region in which the pre-ignition occurrence frequency is smallest among temperature regions of the wall temperature parameter. In a pre-ignition susceptibility operating region A, the wall temperature parameter is controlled so as to fall within the pre-ignition suppression temperature region by operating a cooling water amount varying mechanism 38.
