In an engine that includes a blow-by-gas returning system configured to direct blow-by gas within a crankcase to an intake system through an inside of a head cover, the intake system includes a cover intake-passage disposed at a blow-by-gas outlet of the head cover, and the cover intake-passage communicates with a blow-by-gas passage of the blow-by-gas outlet.

Engine that includes blow-by-gas returning system

There is provided an engine stopping device including a stopping solenoid, where an operating shaft, interlocked to a control rack of a fuel injection pump, is rotatably supported by an engine case in a pass-through manner. The control rack is forcibly movable to a stopping position by an action of the stopping solenoid on an operation arm provided for a projecting portion of the operating shaft in an integrally rotatable manner. An extending-retracting rod of the stopping solenoid and the operation arm are interlocked by fitting engagement between a pin provided for the extending-retracting rod and a cut-out portion of the operation arm. The cut-out portion is configured in a shape elongated along a direction perpendicular to a movement trajectory of the extending-retracting rod.

A cooling structure of a water-cooled engine includes: a plurality of cylindersarranged in a cylinder block; and a water jacket W formed around the plurality of cylinders. The water jacket W includes a pair of main flow pathsformed in a state of extending in a cylinder arrangement direction outside the cylinders, and inter-bore flow pathsformed between adjacent cylindersin a state of connecting the pair of main flow paths. Guide walls, capable of guiding the cooling water flowing in the main flow pathsto the inter-bore flow paths, are formed in the cylinder block

Cooling structure of water-cooled engine

There is provided an engine capable of reducing oil consumption. The engine includes a cylinder head, a cylinder head cover mounted above the cylinder head, a rocker arm covered by the cylinder head cover, and a breather chamber provided inside the cylinder head cover. As a front-rear direction is defined by a longitudinal direction of the cylinder head cover, the breather chamber has a blow-by gas inlet at one side in the front-rear direction, a blow-by gas outlet at another side in the front-rear direction, and an oil discharging guide chamber at an intermediate part in the front-rear direction. The blow-by gas inlet is opened on a bottom wall of the breather chamber, and a peripheral wall of the oil discharging guide chamber is protruded downwardly from the bottom wall of the breather chamber toward between the rocker arm provided at a side of the blow-by gas outlet and the blow-by gas inlet.

An apparatus for and a method of measuring at least one painted layer formed on a sample to be analyzed, which sample may be, for example, a galvanized steel including a substrate having the painted layer formed thereon with or without an intervention of a primer coated layer. In the practice of the invention, radiation is directed onto a surface of the painted layer so as to excite the sample. The intensity of resultant Compton scattering rays, the intensity of resultant fluorescent X-rays emitted from zinc contained in a plated zinc and the intensity of resultant fluorescent X-rays emitted from strontium contained in the primer coated layer are measured, and also the absorption of the fluorescent X-rays are taken into consideration, to provide a basis for calculation of the amount of paint coating forming the painted layer. In this way, the amount of primer and paint material both applied to the galvanized steel can be easily measured on a non-destructive basis.
