    摘要： In multi-cylinder engine in which an intake valve and a first spark plug arranged side by side along an axis of a camshaft and an exhaust valve and a second spark plug arranged side by side along the axis of the camshaft are disposed in a cylinder head for every combustion chamber, the position of a central portion of an upstream end of an intake port provided in the cylinder head with the intake valve interposed between the intake port and each of the combustion chambers and the position of a central portion of a downstream end of an exhaust port provided in the cylinder head with the exhaust valve interposed between the exhaust port and each of the combustion chambers are set to correspond with each other in the direction along the axis of the camshaft. Thus, the length of the cylinder head is reduced.

    摘要： An engine cylinder head in which a water jacket and an EGR passage are formed therein, the EGR passage opening into an exhaust passage at one end and opening into a side of an intake side at the other end thereof, the engine cylinder being characterized in that the EGR passage is provided outwardly in a cylinder arrangement direction of head bolt pass-through holes formed in one end of the engine cylinder head in the cylinder arrangement direction. Thus, because the EGR passage can be made much longer, the cooling capacity for re-circulating gas can be improved. Moreover, because the EGR passage can be provided without head bolts being spaced apart from the combustion chamber, the surface pressure around combustion chambers in the cylinder head relative to a cylinder block can be prevented from being lowered.

    摘要翻译： 一种发动机气缸盖，其中形成有一个水套和一个EGR通道，该EGR通道在另一端开入一端的排气通道和一个进气侧的侧面，其特征在于： EGR通道沿着气缸排列方向在发动机气缸盖的一端形成的头螺栓通孔的气缸排列方向向外设置。 因此，由于可以使EGR通路长得多，所以可以提高再循环气体的冷却能力。 此外，由于在没有与燃烧室隔开的头螺栓的情况下可以设置EGR通路，所以能够防止气缸盖内的燃烧室周围相对于气缸体的表面压力的降低。

    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.
