ABSTRACT:
An internal combustion engine having a cylinder head with integral intake manifold and a planar mounting face which is secured to the cylinder block and on which the exhaust manifold is also mounted. The head member incorporates an open bottomed mixture plenum closed by a heated wall of the exhaust manifold for supplying mixture heat. The plenum receives mixture through an inlet tube perforated to distribute recirculated exhaust gases from an annular chamber in the head. Mixture passes from the plenum through a pair of upwardly angled feeder passages to separate longitudinally aligned distribution passages feeding the intake ports of front and rear groups of cylinders. The head also incorporates an open topped secondary air gallery connected through distribution tubes with the exhaust ports and closed by an extended flange on the engine rocker cover through which air is supplied. The arrangement provides advantages in manufacturing and mixture distribution for improved operation.
