An engine for an outboard motor is provided with an engine body, an intake system configured to supply combustion air to the engine body, an exhaust passage formed by connecting the engine body and middle and lower units thereunder, a catalyst provided in the exhaust passage, and an air pump configured to supply secondary air to an upstream side of the catalyst. The intake system is arranged in a side portion of one side of the left or right side of the engine body, and the exhaust passage and the air pump are arranged in a side portion of the other side of the left or right side of the engine body.

Engine for outboard motor

An intake system is arranged in a side portion of one side of an engine body in a left-right direction, and the exhaust passage and the air pump are arranged in a side portion of the other side of the cylinder block and the cylinder head of the engine body in the left-right direction.

In an exhaust passage, an exhaust manifold connected to exhaust ports of each cylinder of an engine body and formed to extend vertically is arranged in a side portion of a cylinder head. A secondary air supply system has an intake silencer, a check valve configured to permit only a flow to the exhaust passage side, a secondary air supply control valve configured to control a flow rate of the secondary air, and a secondary air supply passage configured to connect those components to each other and the exhaust passage. The secondary air supply system is arranged in a side portion of a cylinder block placed between a crankcase of the engine body and an assembly of the exhaust manifold and the cylinder head.

An engine for an outboard motor is provided with an engine body, an intake system configured to supply combustion air to the engine body, an exhaust passage formed by connecting the engine body and the middle and lower units thereunder, a catalyst provided in the exhaust passage, and an air pump configured to supply secondary air to the upstream side of the catalyst. The air pump is driven by an electric motor.

A snowmobile having improved drive stability of the vehicle body during steering includes a pair of left and right skis on a front side of the vehicle body, a steering shaft disposed on a front of a saddle type seat for steering the skis, an engine mounted in a cowling that covers the front side of the vehicle body, and a crawler disposed on a rear side of the vehicle body for driving the snowmobile. The engine is mounted by inclining a cylinder axis thereof forward, and the steering shaft is disposed on the front of a cylinder head of the engine.

A method for manufacturing a semiconductor device comprises dry-etching a thin film using a resist mask carrying patterns in which at least one of the width of each pattern and the space between neighboring two patterns ranges from 32 to 130 nm using a halogenated carbon-containing compound gas with the halogen being at least two members selected from the group consisting of F, I and Br. The ratio of at least one of I and Br is not more than 26% of the total amount of the halogen atoms as expressed in terms of the atomic compositional ratio to transfer the patterns onto the thin film. Such etching of a thin film avoids causing damage to the resist mask used. The resulting thin film carrying the transferred patterns is used as a mask for subjecting the underlying material to dry-etching.

Semiconductor device and etching apparatus

An engine for a snow vehicle has a crank shaft supported by a crank case along the width direction of the snow vehicle. An oil pan is disposed below the crank case. A cylinder block is disposed above the crank case. The engine is mounted on the snow vehicle such that an axis of the cylinder block is inclined rearward. An oil pump is disposed behind and below the crank shaft. An oil filter is disposed in front of the crank shaft.

Arrangement structure of auxiliaries of engine for snow vehicle

A breather device provided in a 4-cycle engine which is configured to be mounted on a front part of a vehicle body of a snow vehicle, the 4-cycle engine including a crankcase, a crankshaft rotatably supported on the crankcase and provided in a state substantially parallel to the snow vehicle width direction, and a magnet unit connected to one end of the crankshaft, wherein the breather device includes a breather chamber integrally provided on a lateral side of the 4-cycle engine at the same side of the magnet unit and the breather chamber is disposed above the magnet unit in a side view.

Breather device and engine

An engine starter mechanism arrangement for snow vehicles, in which a starter mechanism is disposed so as to maintain excellent traveling stability of the snow vehicle. A crankshaft () extends through an engine () in a transverse direction of a body frame. A rear balancer shaft () is disposed in a rear part of the engine at a location rearward of the crankshaft in a manner extending substantially parallel to the crankshaft. A starter motor () is disposed in the engine at a location above the rear balancer shaft.

A lubricating structure for engines, wherein an oil feed pump and an oil recovery pump are disposed so as to avoid interference between the oil feed and recovery pumps and a clutch mechanism and an increase in the size of the engine. The clutch mechanismis disposed at a location toward a left end of a crankshaftas an output shaftwhich is rotatably supported between an upper crankcaseand a lower crankcasethat is, disposed on a left side of an engine room. A magnet coveris fixed to right side parts of the two crankcasesA magnet MG is disposed between the two crankcasesand the magnet coverat a location toward a right endof the crankshaftAn oil pump FEP for feeding lubricating oil is disposed between the two crankcasesand the magnet coverand an oil pump SCP for recovering lubricating oil is disposed between the two crankcasesand the magnet cover

Lubricating structure for engines, lubricating structure for engines for snow vehicles, and snow vehicle

A four-stroke-cycle engine of a vehicle such as snowmobile comprises a crank case, which is dividable into a plurality of crank case components having mating surfaces, through which the crank case is assembled, a crank shaft rotatably supported in the crank case at a portion between the mating surfaces of the crank case components, and a belt driven-type continuously variable transmission mechanism operatively connected to one end of the crank shaft through a clutch belt. The continuously variable transmission mechanism includes a drive shaft, and the clutch belt is stretched around the drive shaft and the crank shaft so that a tensioning direction of the clutch belt is shifted from a line passing the mating surfaces of the crank case components at a predetermined angle therebetween.

Four-stroke-cycle engine provided with belt driven-type continuously variable transmission mechanism

A snowmobile provided with a water-cooling type engine has a body, half of which is covered by an engine hood so as to form an engine room therein. The water-cooling engine is transversely mounted in the engine room, and the engine includes a crank case, a cylinder block disposed above the crank case, a cylinder head disposed above the cylinder block, and a crank shaft rotatably supported in a manner inclined rearward. The cylinder head is covered by a head cover so that a mating surface thereof is inclined forward such that a front side of the cylinder head is lower, in level, than a rear side thereof.
