Document Type and Number:
Japanese Patent JPS5239128
Kind Code:
B2
Abstract:
An intake and exhaust manifold assembly is provided for an internal combustion engine of the type in which each main combustion chamber is connected to an auxiliary combustion chamber, respectively, through a torch nozzle. The rich mixture supplied to the auxiliary chamber is ignited to cause a torch flame to be projected through the torch nozzle to ignite a lean mixture supplied to the main chamber. The intake manifold includes a riser for the rich mixture and the lean mixture, together with intake passages for the auxiliary combustion chambers and main combustion chambers. The exhaust manifold comprises a split housing enclosing and spaced from a thin wall metal liner. The intake manifold is secured in position on top of the exhaust manifold. Heat-receiving surfaces on the intake manifold are placed above aligned openings in the liner and upper half of the housing to heat both the lean mixture and rich mixture by the heat of the exhaust gases. The liner is secured to the upper half of the split housing by means of fasteners near the aligned openings. The liner is otherwise free to move by thermal expansion relative to the enclosing housing. A baffle plate in the liner directs exhaust gases toward said aligned openings.
