摘要： The object of the present invention is to facilitate an appropriate oil supply to the tensioner without a complex apparatus. A valve chamber 3A is formed in a cylinder head 3 which is connected to a cylinder block 2. An opening 23—for discharging the oil in the valve chamber 3A into a chain case 6 which is placed on the side of the cylinder block 2—is formed on a chain case mounting surface 20. Inside the chain case 6 on the chain case mounting surface 20 of the cylinder block 2 are placed a timing chain 15 and a tensioner 30 for applying tension to the timing chain 15. An oil dropping rib 24 for guiding the oil discharged through the opening 23 to the tensioner 30 is provided on the chain case mounting surface 20.

摘要： A multi-cylinder internal combustion engine includes an intake manifold having branch pipes connected to one side of a cylinder head and curved to allow the intake manifold to extend to directly above a cylinder-head cover, and intake-side spark plugs and fuel injectors which are incorporated in the cylinder head. The spark plugs are disposed outside a valve train chamber on a side of the valve train chamber where curved portions of the branch pipes are disposed, and the fuel injectors and ignition coils provided above the spark plugs are disposed between the valve train chamber and the curved portions in a direction normal to axes of the cylinders as viewed from a direction in which cylinders are arranged. The ignition coils are disposed so as not to overlap the branch pipes as viewed from a direction in which the ignition coils are attached to the cylinder head.

摘要： Disclosed is a process for the preparation of maleic anhydride which comprises subjecting an aliphatic hydrocarbon having four or more carbon atoms to gas phase oxidation reaction in the presence of a catalyst, wherein supposing that the function of reaction product gas composition is FL and the function of temperature and pressure of reaction product gas is FR, the safety index F satisfies the following relationship (1): F=FL−FR>0 (1) According to the present invention, it is possible that the loss of unreacted hydrocarbon and maleic anhydride as reaction product due to non-catalytic oxidation reaction is prevented while effecting the reaction in a stable manner, whereby the yield of maleic anhydride can be kept maximum while assuring safety.
