Abstract: An internal combustion engine with a supercharger with a piston arranged to be inserted into a cylinder so as to move in a reciprocating way, which has a bore size of the cylinder ranging from approximately 43 mm to 67 mm; a volume of a single chamber of the cylinder ranging from approximately 110 cc to 400 cc; a ratio of a stroke of the piston to the bore size of the cylinder being larger than 1; and a compression ratio of the engine being 9 or larger.

Abstract: An internal combustion engine of a spark ignition type is so arranged as to set an air-fuel ratio of a mixed fuel to become substantially stoichiometric in the range of from A/F=13 to A/F=16 at the time of running in a high load region and to recirculate exhaust gases into the intake system. For the internal combustion engine of a natural intake type, the compression ratio is preferably set to 11 or larger; for the internal combustion engine of a supercharging type, the compression ratio is preferably set to 9 or larger. The rate at which the exhaust gases are recirculated is preferably set to be constant or to become larger as the load of the engine becomes larger.

Abstract: The supercharged internal combustion engine is so adapted as to set the air-fuel ratio to become a lean air-fuel ratio which is leaner than stoichiometric and lean enough to maximize improvements in a rate of consumption of fuel, for example, to the A/F ratio of 16, when the supercharger exists in such a supercharging region as demonstrating its sufficient degree of supercharging capability. When the air-fuel ratio is made lean in the supercharging region, exhaust gases are recirculated into the intake system of the engine, in addition to a mixed fuel. Preferably, the exhaust gases having lower temperatures are recirculated at the time of a high load of the engine in the supercharging region, while the exhaust gases having higher temperatures are recirculated at the time of a low load of the engine therein.

Abstract: A cam shaft support device for an engine includes a cam carrier. A plurality of bearings are integrally formed with the cam carrier so as to rotatively support two cam shafts installed on a cylinder head. Each of the bearings are provided with a slit on a lower portion thereof so as to reduce the sliding resistance between the bearings and the cam shafts.

Abstract: The engine is provided with an auxiliary chamber having an auxiliary chamber port with an opening communicated with the combustion chamber. The auxiliary chamber port is arranged to be opened or closed with an auxiliary chamber valve. The timing of closing the auxiliary chamber valve is in between a final stage of compression stroke in which the temperature within the cylinder becomes higher and an initial stage of explosion stroke. On the other hand, the timing of opening the auxiliary chamber valve is in a middle stage of the compression stroke, thereby allowing the mixed fuel cooled in the auxiliary chamber to be replaced with a portion of the mixed fuel in the combustion chamber, thereby lowering the temperature within the cylinder.

Abstract: In a V-type engine with two bore-offset banks opposed to one another at a predetermined angle, an accessory mechanism is provided between the two banks. A drive belt for the accessory mechanism is disposed on the side of one of the banks which is recessed inwardly due to the bore offset. In another embodiment, the accessory mechanism is a supercharger driven by a balancing shaft which, in turn, is driven by the crank shaft. In yet another embodiment, the V-type engine has a separate timing belt for each bank, that is, a first timing belt for the bank which is recessed inward because of the bore offset, and a second timing belt for the bank which juts out because of the bore offset. A drive belt is provided for driving the supercharger. The belts are arranged in the following order from the inside outward: the second timing belt, the first timing belt and the accessory belt.

In addition to a fuel injector disposed in one of the intake ports, a secondary fuel injector, energized so as to inject fuel when the engine operates at lower loads, is preferably disposed adjacent the intake valve located in the one intake port.

Abstract: A coating method contains a coating step for spraying the surface of a coating substrate paint with a paint and a drying step for drying the paint coated thereon. The paint coated on the substate is then caused to flow or sag artificially within the coat in the drying step by application of an action from the outside at least in one of the coating and drying steps, namely, by heating or vibrating the paint coated thereon. During the flowing or sagging of the paint artificially, the substrate is rotated about its axis extending substantially horizontally in a longitudinal direction of the substrate at a speed which is high enough to rotate the substrate before the paint coated thereon substantially sag due to gravity yet which is low enough so as to cause no sagging as a result of centrifugal force.

Abstract: Engine valve driving apparatus including a camshaft rotatable with a crankshaft of the engine with a movable cam member supported in sliding fit by the camshaft for axial movement but prevented from any rotation relative to the camshaft. An engine valve is driven by the movable cam member, and a hydraulic system axially shifts the movable cam member between an operative position where the movable cam member is brought into cooperation with the engine valve and an inoperative position where the movable cam member is completely out of cooperation with the engine valve. The hydraulic system causes the shifting movement of the movable cam member according to engine operating conditions so that the engine valve is driven at different speeds or different timings.
