摘要:
Provided is a slide bearing 1 with which friction can be reduced and the total amount of effluent oil can be reduced. In the slide bearing (1) in which the halved members (2), (2) made by dividing the cylinder in two in the direction parallel to the axial direction are disposed vertically, the narrow grooves (33) are provided at an end of the lower halved member (2) in the circumferential direction from a mating surface on a downstream side of a rotation direction to a predetermined bearing angle (ω1) and peripheral edge parts (32a) are provided outside the narrow grooves (33) in an axial direction.
摘要:
An oil deterioration suppressing apparatus for an internal combustion engine comprises a first oil filter (45, 55) and a second oil filter (20, 46, 46', 56), wherein the first oil filter comprises a first filter (45, 55) member for filtering oil from an oil pan (41) in which oil is stored, and the second oil filter (46) comprises a second filter member for filtering oil from the oil pan (41), and wherein the second filter member is made of a ceramic material and has a mean pore size smaller than the mean pore size of the first filter member.
摘要:
Provided is a control apparatus for an internal combustion engine which can favorably achieve a good balance between the prevention of an excessive increase in the piston temperature and the prevention of deterioration of various performances of the internal combustion engine as a result of execution of abnormal combustion suppression control, even when abnormal combustion occurs continuously or substantially continuously over a plurality of cycles. An in-cylinder pressure sensor (34) is provided to obtain the in-cylinder pressure P of an internal combustion engine (10). When continuous pre-ignition is detected using the in-cylinder pressure sensor (34), the control apparatus makes it more difficult for continuous pre-ignition suppression control to be executed when the Pmax at the time of pre-ignition is low than when the Pmax at the time of pre-ignition is high.
摘要:
The present invention is provided with a configuration which makes it possible to inhibit contact between an oil (L) and a gas in an oil pan (10a) properly. The oil pan (10a) according to the present invention contains a film (S1) which covers an oil surface (F) of the oil (L) to separate the stored oil (L) and the gas above the oil (L). The film (S1) can float by receiving buoyancy in the oil (L). The film (S1) may be formed of a liquid. The film also may be configured by a film member.
摘要:
A body of an oil jet is provided with: an oil supply port; a cylinder; and an oil injection port. A piston valve is accommodated in the cylinder. The piston valve forms in the cylinder a differential pressure room which is a closed compartment. In the piston valve, an orifice which makes the differential pressure room being communicated with a side of the oil supply port is formed. The piston valve is biased toward a position at which the oil injection port is closed by a spring. A first oil injection nozzle is connected to the oil injection port. A leak hole which allows oil to be leaked outside of the cylinder from the differential pressure room is open at the side surface of the cylinder. Further, a second oil injection nozzle is connected to the leak hole.
