摘要： A constitution of protecting a fuel delivery tube of an engine, includes: 1) an engine body including: a) a cylinder head, and b) a ladder cam bracket defining an outer wall on a side section thereof, including: i) an outer frame, ii) an intake cam bracket, and iii) an exhaust cam bracket integrated with the outer frame and holding an exhaust cam shaft; 2) the fuel delivery tube disposed beside the engine body and extending in a direction substantially along a row of a cylinder; and 3) an intake manifold made of a material free from a metal. The outer wall of the ladder cam bracket is formed with a protrusion which protrudes toward a branch section of the intake manifold in such a manner as to prevent the branch section of the intake manifold from causing an interference with the fuel delivery tube.

摘要： A crankcase emission control device of an internal combustion engine comprises a gas/liquid separator that separates an oil mist from blow-by gases flowing therethrough. A first passage is defined in both a crankcase and a cylinder head to connect an interior of the crankcase to a valve rocker cover chamber defined by the cylinder head. A second passage extends from the valve rocker cover chamber to the gas/liquid separator. A third passage extends from the gas/liquid separator to an intake system of the engine. For reducing the height of the entire construction of the engine, the gas/liquid separator is integrally formed by the cylinder head at a position below intake ports of the cylinder head.
