  • Publication number: 20100065011
    Abstract: A four-cycle air-oil cooled engine includes a cylinder head having a spark plug mounting hole formed therein, and a ring-like groove formed therein and surrounding the spark plug mounting hole. The cylinder head is formed with first and second co-planar sealing surfaces, disposed on a plane perpendicular to an axis of the spark plug mounting hole, and having an opening end of the ring-like groove disposed therebetween. The ring-like groove defines an oil jacket around the periphery of the spark plug mounting hole. A cover member having a flat surface opposed to the first and second flat sealing surfaces of the cylinder head is secured to the cylinder head such that a single gasket is interposed between the first and second sealing surfaces and the flat surface of the cover member.

  • Patent number: 7610139
    Abstract: An in-cylinder pressure detection device for an internal combustion engine, which is capable of detecting an in-cylinder pressure accurately without being adversely affected by changes in the atmospheric pressure even when the atmospheric pressure changes. An in-cylinder pressure sensor detects pressure within a cylinder as a detected in-cylinder pressure. An ECU estimates pressure generated in the cylinder during a non-combustion period as a motoring pressure. An atmospheric pressure sensor detects an atmospheric pressure (PA). The ECU corrects the motoring pressure according to the atmospheric pressure and identifies correction parameters such that the difference between the detected in-cylinder pressure detected during a compression stroke of the engine and the corrected motoring pressure becomes minimum, and corrects the detected in-cylinder pressure by the identified correction parameters, to thereby calculate an in-cylinder pressure.

  • Patent number: 7606650
    Abstract: An in-cylinder pressure detection device for an internal combustion engine, which is capable of calculating a hysteresis amount properly to thereby detect in-cylinder pressure with high accuracy. The in-cylinder pressure detection device comprises an in-cylinder pressure sensor that detects in-cylinder pressure as a detected in-cylinder pressure. The in-cylinder pressure detection device estimates an in-cylinder pressure generated when combustion is not performed in the cylinder, as a motoring pressure, calculates a hysteresis amount indicative of a difference between the detected in-cylinder pressure and an actual in-cylinder pressure, based on the detected in-cylinder pressure and the motoring pressure obtained during the exhaust stroke of the engine, and corrects the detected in-cylinder pressure based on the calculated hysteresis amount.

    Abstract: A lubricating structure for an engine includes a crankcase for supporting a crankshaft formed from a pair of case halves coupled to each other along a mating plane extending along a plane perpendicular to an axial line of the crankshaft. An oil reservoir in a lower portion of the crankcase extends across the mating plane. A pump chamber of an oil pump is formed between the two case halves across the mating plane. Lubricant is drawn from the oil reservoir into the oil pump using a structure which can achieve reduction of the number of parts and improve the ease of assembly. The structure includes a path groove, which forms an oil suction path for interconnecting the oil pump and the oil reservoir, formed in at least one of the two case halves.
