A hydraulic control apparatus (1) is provided with an oil pump (4) that draws oil from an oil pan (3) due to the rotation of the crankshaft, a piston jet (6) that open when the hydraulic pressure of the oil that has been drawn from this oil pump (4) attains a valve opening pressure Qa and injects oil toward a piston through an oil injection path (5), a relief valve (8) that is disposed on an oil return path (7) and opens when the hydraulic pressure of the oil that has been drawn by the oil pump (4) has attained a valve opening pressure Qb, and a switching valve (9) that is disposed on the oil return path (7). The valve opening pressure Qb is set to a pressure that is lower than that of the valve opening pressure Qa.

According to an internal combustion engine of the invention, release operation of an antitheft device is selected as an event generating by necessity prior to the starting of an engine, and the pre-heat is started based on the generating timing of the selected event. The start timing of the release operation of the antitheft device is high in terms of both necessity as an event generating prior to the starting of the engine and reproducibility of the time length from its start timing to an arbitrary starting timing of the engine. The pre-heat completed state can be secured by starting the pre-heat synchronously with this timing or at a predetermined timing based on the timing, even when the engine is started at an arbitrary timing. Exhaust characteristics and fuel consumption performance can be improved by optimizing the temperature distribution of the engine at starting.

A warm-up control device for an internal-combustion engine comprises a heat storage device for storing a heating medium heated during operation of the engine, supplies the heating medium stored in the heat storage device to a drive device (a transmission and the like) prior to the start of the engine or:at the start of the engine, and supplies the heating medium stored in the heat storage device to the drive device while maintaining a condition where the heating medium is circulated in the path excluding the heat storage device and including the drive device after the start of the engine. The warm-up control device supplies the heating medium heat-insulated and stored in the heat storage device during operation of the engine, and sets the ratio between the amount of the heating medium supplied from the heat storage device to the and the amount of the heating medium supplied from the heat storage device to the drive device, on the basis of the temperature of the engine and the temperature of the drive device. At the start of the internal-combustion engine, the heating medium can be supplied to the engine or the drive device efficiently, and the warm-up can be performed as required.
摘要:
An oil pan is provided with an oil pan separator that partitions a first chamber that communicates with a moving part inside a cylinder block and a second chamber outside the first chamber. A communicating hole is provided to a bottom panel of the oil pan separator. The communicating hole is shielded from a strainer.

An oil pan separator 132 is disposed so as to divide a space within an oil pan 130 into a first chamber 30a and a second chamber 30b. The oil pan separator 132 has a protrusion 132b formed at a low position in such a manner that a portion of the first chamber 30a protrudes into the second chamber 30b. A protrusion upper-plate 132b1, which serves as an upper end portion of the protrusion 132b, is provided with an oil feed valve 138, which is a one-way valve, for allowing substantially only outflow of oil from the first chamber 30a to the second chamber 30b.

摘要:
The internal combustion engine includes an engine preheating apparatus for preheating the internal combustion engine upon or before starting thereof. This internal combustion engine further includes an air-fuel ratio controller for setting an air-fuel ratio of the internal combustion engine that is preheated, to a value higher than that of the internal combustion engine that is not preheated, and/or an ignition-timing controller for retarding an ignition timing of the internal combustion engine that is preheated as compared with the ignition timing of the internal combustion engine that is not preheated.
