20080236526 | Valve actuating mechanism for an internal combustion engine, and cylinder head incorporating same - A valve actuating mechanism for an internal combustion engine includes a first rocker arm moving mechanism, a second rocker arm moving mechanism, and a trigger arm. The first rocker arm moving mechanism moves left and right rocker arms from a first operation position side to a second operation position side. The second rocker arm moving mechanism moves the left and right rocker arms from the second operation position side to the first operation position side, and the trigger arm selectively restricts the movement of the left and right rocker arms. During engine operation, left and right rocker-side key portions of the left and right rocker arms, respectively, and left and right trigger-side key portions of the trigger arm selectively maintain or remove a restriction on the movement of the left and right rocker arms, in response to a rocking state of the left and right rocker arms. | 10-02-2008 |
20080236531 | Valve actuating mechanism for an internal combustion engine, and engine incorporating same - A valve actuating mechanism for an engine having a rocker arm movement restraining device which controls opening and closing an engine valve. The rocker arm movement restraining device includes a timing arm which engages left and right rocker arms for constraining the axial movement thereof, and a timing cam disposed on an intake-side camshaft. The rocker arm movement restraining device releases the engagement of the timing arm with the left and right rocker arms by activating the timing arm when the intake-side camshaft is rotated, and when the timing arm releases the engagement with the left and right rocker arms, the left and right rocker arms move to a predetermined operating position. | 10-02-2008 |
20080264369 | Valve-actuating system for an internal combustion engine, engine incorporating same, and method of using same - A valve-actuating system for an engine, in which left and right rocker arms are moved in axial directions of a rocker arm shaft to one of a first operating position in which the rocker arms are allowed to abut on first cams, and a second operating position in which the rocker arms are allowed to abut on second cams. The rocker arm shaft is slidably supported by an engine frame so as to be movable in the axial directions thereof. During an engine operation, when the left and right rocker arms are about to be selectively moved to one of the operating positions, the rocker arm shaft is moved in advance to the same side of the selected one of the operating positions, and thereafter the left and right rocker arms are moved to the selected one of the operating position. | 10-30-2008 |
20090056654 | Valve actuating mechanism for an internal combustion engine, and cylinder head incorporating same - A valve actuating mechanism includes a first rocker arm moving mechanism including a first spring for urging left and right rocker arms from a first operation position side towards a second operation position side. The valve actuating mechanism also includes a second rocker arm moving mechanism including a second spring for urging the left and right rocker arms from the second operation position side towards the first operation position side. When a predetermined force is applied to the left and right rocker arms by one of the respective springs, the rocker arms are configured to be moved to operation positions corresponding to the applied force. | 03-05-2009 |
20100126459 | FIXATION STRUCTURE FOR VALVE SYSTEM ROTATION SHAFT OF INTERNAL COMBUSTION ENGINE - A fixation structure for a valve system rotation shaft of an internal combustion engine to support a camshaft with a cylinder head through the use of a lower cam holder and cam caps, which are formed separately from the cylinder head. The fixation structure eliminates the necessity of taking special vibration/noise control measures for a head cover thus preventing an increase in the cost, size, and weight of the head cover. A head external wall extends toward the head cover rather than toward a head middle surface in such a manner so as to cover the circumference of the lower cam holder fixed to a head middle surface. The connection to the holder fixation section is established with the base end of an external wall of the head cover abutted on the leading end of the head external wall. | 05-27-2010 |
20100242914 | INTAKE PASSAGE STRUCTURE FOR INTERNAL COMBUSTION ENGINE, AND ENGINE AND VEHICLE INCORPORATING SAME - An internal combustion engine includes an intake passage structure. The engine is configured such that a cylinder head is formed integrally with an intake manifold portion. A cylinder central axis is oriented parallel to an extending direction of an intake passage, when viewed in a side view. An injector is arranged such that it does not interfere with peripheral components, including the intake passage and a throttle body. The injector is disposed in the intake manifold portion such that a leading end thereof is oriented towards the intake valve of the cylinder head. The intake passage on the upstream side of an injector attachment position is offset from the injector in a width-direction of the internal combustion engine. | 09-30-2010 |

20100099809 | PAINT COMPOSITIONS - Disclosed is a paint composition comprising a (A) polyester resin comprising a hydroxyl group value of from 10 to 35 mgKOH/g, an acid value of not more than 15 mgKOH/g and a number average molecular weight of from 2,000 to 6,000, a (B) acrylic resin comprising a hydroxyl group value of from 50 to 150 mgKOH/g, an amine value of from 10 to 50 mgKOH/g, a number average molecular weight of from 1,500 to 8,000 and a glass transition temperature of from 0 to 50° C., and a (C) polyester resin comprising a hydroxyl group value of from 50 to 150 mgKOH/g, an acid value of not more than 20 mgKOH/g and a number average molecular weight of from 1,000 to 4,000. | 04-22-2010 |
20100129558 | PAINT FILMS WHICH HAVE EXCELLENT HEAT-RADIATING PROPERTIES, AND A METHOD FOR THEIR FORMATION - To provide paint films which have excellent heat-radiating properties and with which many colors with light colors in the main can be obtained. (Means of Resolution). A paint film which has excellent heat-radiating properties which comprises an undercoat paint film layer which contains from 1 to 20 mass % with respect to the total solid fraction of the paint film of carbon black and a top-coat paint film layer which contains 1 to 40 mass % with respect to the total solid fraction of the paint film of a pearl pigment and which does not contain aluminum powder and the paint film thickness of the top-coat paint film layer is from 11 to 50 μm which can be formed with a method of forming paint films which have excellent heat-radiating properties wherein an undercoat paint which contains from 1 to 20 mass % with respect to the total solid fraction of the paint film of carbon black is applied and hardened and an undercoat paint film layer is formed and then a top-coat paint which contains 1 to 40 mass % with respect to the total solid fraction of the paint film of a pearl pigment and which does not contain aluminum powder is applied over said undercoat paint film layer and hardened and a top-coat paint film layer of which the paint film thickness is from 11 to 50 μm is formed. | 05-27-2010 |
