Filed: 1976-03-09
Abstract: 1522867 Exhaust passages in cylinder heads NISSAN MOTOR CO Ltd 9 March 1976 [15 March 1975] 09373/76 Heading F1B An I.C. engine has a cylinder block defining two cylinders and a bolted-on cylinder head defining respective combustion chambers for the cylinders, the head having an exhaust passage including a first portion which extends between the exhaust ports of the two combustion chambers and a second portion one end of which connects with the first portion and the other end of which opens to a longitudinal side of the head, forming an exhaust gas outlet, the outlet being located at one of two portions of the head, the portions being defined by an imaginary vertical plane, perpendicular with respect to the longitudinal axis of the head and disposed intermediately between the two combustion chambers. Fig. 3 shows a four-cylinder engine in which passage portion 40a joins exhaust ports 41a and 41b and communicates with passage portion 40b leading to port 43 in the longitudinal side wall of the head. A similar passage leads from the exhaust ports of the other two cylinders to port 44. Exhaust gases are afterburnt in manifold/reactor 50. This arrangement reduces heating of the cylinder head in the vicinity of the head bolts 34 and prevents excessive longitudinal expansion of the bolts which can cause leaking at the cylinder head gasket. Figs. 5, 6 and 7 (not shown) relate to alternative shapes of portions 40a and 40b which provide for the distance from the exhaust ports 41a, 41b to port 43 to be the same so as to prevent interference between the gas flows from the combustion chambers. A double-walled liner (56a, 56b) Figs. 9 and 10 (not shown) may be provided in both portions of the passage. The passage may be of circular or oval cross-section and the crosssectional area of portion 40b is the same as, or up to twice the cross-sectional area of portion 40a. A duct 58 may be provided to feed secondary air into reactor 60. Fig. 18 (not shown) relates to a cross-flow four-cylinder engine in which the two outer cylinders are supplied with a richer-thanstoichiometric mixture and the two inner cylinders are supplied with a leaner-than-stoichiometric mixture. The exhaust gases are mixed and afterburnt in the reactor. The passage portions 40b and 42b may be extended, by means of tubes,  into the central region of the reactor, the tube ends being opposed so that thorough mixing of the gases occurs. Fig. 21 (not shown) relates to an engine having exhaust passages similar to those of the Fig. 3 engine, but also having auxiliary chambers in which ignition is initiated and from which a jet of flame issues to ignite the mixture in the main chamber. The auxiliary chamber mixture is richer-than-stoichiometric and the main chamber mixture is leaner-thanstoichiometric.
