Abstract: An apparatus for controlling oil pump pressure includes a sensor for sensing knocking of an engine, an oil pump configured to determine a pressure for discharging engine oil toward a piston of the engine, and a control unit configured to control the pressure of the engine oil discharged toward the piston by determining whether the knocking occurs based on a parameter transmitted from the sensor for determining whether the knocking occurs, and by controlling the oil pump based on whether the knocking occurs in the engine.

Abstract: Disclosed is lubrication for a slow-running two-stroke engine, especially marine diesel engines. The lubrication uses Swirl Injection Principle by locating the lubricant injectors closer to the TDC than ⅕ of the full stroke of the piston, which is closer than in typical marine diesel engines. This can be achieved by reconstructing cylinder liners or by adding new mounting holes to the cylinder. In case that such reconstruction is not possible, an improvement of SIP principles can also be achieved by directing the spray towards the TDC or to a location on the cylinder liner closer to the TDC as compared to the location of the SIP valves, for example under an angle of more than 30 degrees or even more than 60 degrees when measured from a plane normal to the cylinder axis.

Abstract: A piston cooling jet includes a first body and a second body. The first body includes a housing having an inlet fluidly coupled with nozzle outlets. The second body is coupled to the first body to form an interior chamber disposed inside the first body and the second body. The interior chamber is fluidly coupled with the inlet and the nozzle outlets. The interior chamber directs fluid received via the inlet through the nozzle outlets and out of the piston cooling jet assembly in a direction towards a spray target.

Abstract: An oil supply apparatus includes: an oil pump; a main oil supply path; a sub oil supply path connected to the main oil supply path; a first oil supply section which is connected to the main oil supply path and which supplies oil to a crank bearing section of a specific crank journal; a second oil supply section which is connected to the sub oil supply path and which supplies oil to a crank bearing section of a crank journal other than the specific crank journal; and a control apparatus which sets, as a target oil pressure, a highest required oil pressure among required oil pressures required from a plurality of hydraulic operating sections in accordance with an operation state of the engine, and which controls the discharge amount of the oil pump so that an oil pressure detected by an oil pressure sensor equals the target oil pressure.

Abstract: 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.

Abstract: A ferrous piston for gasoline powered engines having dimensions which achieve reduced mass and improved performance is provided. The piston crown has a thickness of less than 4 mm and includes valve pockets with an axial clearance between the valve pockets and an uppermost ring groove of less than 1.5 mm. The pin bosses have an axial thickness of less than 3.7% of a bore diameter, which is the largest outer diameter of the piston, measured between a pin bore and the crown at 1 mm from an inner face forming the pin bore. Each pin boss has a radial thickness of less than 3% of the bore diameter measured between the pin bore and a lower end of the pin boss. An undercrown surface presents a projected area of less than 45% of a total piston bore area, wherein the total piston bore area is πBD2/4, BD being the bore diameter.

Abstract: An internal combustion engine has a lower link rotatably mounted to a crankpin of a crankshaft, an upper link having a first upper link end rotatably connected to a piston pin of a piston and a second upper link end rotatably connected to a first lower link end side of the lower link through a first connecting pin, and a control link having a first control link end supported on a cylinder block and a second control link end rotatably connected to a second lower link end side of the lower link through a second connecting pin. When viewed in an axial direction of the crankshaft, the second connecting pin is arranged to swing along a lateral direction substantially perpendicular to a center axis of a cylinder of the internal combustion engine.

Abstract: An oil level regulating apparatus includes a valve unit and a solenoid unit. The valve unit includes a housing having an inflow hole, an outflow hole, and a leak hole, a partition separating the outflow hole and the leak hole, defining a valve chamber close to the outflow hole, and having a partition continuous hole, a valve dividing the valve chamber into an introduction chamber and a pressure chamber and having a valve continuous hole, and a valve biasing member biasing the valve. The solenoid unit has a shaft configured to open and close a leak channel. The shaft can open and close the leak channel on the downstream side of the pressure chamber. When the shaft closes the leak channel, the valve is switched to a closed valve state of closing the outflow hole.
