Abstract: The present invention provides a cooling structure of a fuel injection valve that can cope with the high load operation of the engine by efficiently transferring heat from a nozzle to a cylinder head, thereby improving the cooling efficiency of the injection valve including the nozzle valve. In the cooling structure, fuel is injected through an injection hole by opening and closing of the needle valve 2 that is reciprocatably fit inside the nozzle and removably attached to a seating portion of the nozzle at a tip. The cooling structure comprises a metal ring member 10 which is interposed between an outer circumferential face of the nozzle nut 3 and an inner circumferential face of the outer sleeve 6 so as to transfer heat from the nozzle 1 to the cylinder head 110 via the nozzle nut 3 and the outer sleeve 6.

Abstract: An object of the present invention is to propose a structure of a crankcase capable of coping with increased combustion pressure inside a cylinder of an engine by a simple and inexpensive means for suppressing the deformation at a middle section between adjacent fastening bolts in a direction connecting the centers of adjacent cylinders. The structure of the crankcase which has a plurality of cylinders and a plurality of bolts arranged on both sides of each of the cylinders for fastening the cylinders to a cylinder head, the structure of the crankcase comprises a reinforcing rib 6 formed on an outer wall of the cylinder at a middle section between the adjacent fastening bolts 3 in a direction 20 connecting centers of the adjacent cylinders, the reinforcing rib extending downward continuously from the cylinder top plate in a direction parallel to a center line 4a of the cylinder.

Abstract: A tire inflation pressure monitoring device includes transmitters for transmitting air pressure signals indicative of air pressures in tires, detected by respective air pressure sensors, and a receiver for generating a warning signal in accordance with the air pressure signals received from the transmitters. The air pressure signal transmitted from each of the transmitters includes an ID of the corresponding transmitter as an ID signal. When the receiver is in an ID registration mode in which the IDs of the transmitters are registered (S12), the transmitters are forced to transmit the air pressure signals, and if the number of the received air pressure signals is equal to a predetermined value, the receiver registers the IDs of the transmitters based on the ID signals included in the received air pressure signals (S20, S26).
