<p>PURPOSE:To make the constitution of the piping of a blow-by gas passage easier by providing a stiffener to an intake manifold integrally and providing a blow-by gas passage to connect a union and a throttle body provided to the stiffener, inside the stiffener. CONSTITUTION:In a space between the first and the second cylinder banks 6-1 and 6-2 of a V-engine, an intake manifold 14 erected to the first and the second engine heads is provided, on which a stiffener 20 to hold a throttle body 24 is provide integrally. To the stiffener 20, a union 22 for blow-by gas oriented in a specific direction is provided, a hose 30 for blow-by gas is installed to one end position of the union 22, and the second cylinder head cover 4-2 is installed to the other end position of the hose 30. Furthermore, a blow-by gas passage 26 is provided in the stiffener 20, which is opened to the union 22 as the starting end, while opened in the throttle body 24 as the finishing end.</p> |
