PCT No. PCT/GB96/60160 Sec. 371 Date May 26, 1998 Sec. 102(e) Date May 26, 1998 PCT Filed Jul. 5, 1996 PCT Pub. No. WO97/13967 PCT Pub. Date Apr. 17, 1997An internal combustion engine is described comprising a cylinder having an intake port [14], and two manifolds [24, 34] having branches [22, 32] that are configured to supply two gas streams to the intake port [14] of each cylinder. The two streams enter the cylinder separately so as to produce a stratified charge within the engine cylinder. The first manifold [24] supplies a metered quantity of air within which the fuel to be burnt is dispersed and the second manifold [34] supplies dilution gases. A flow obstructing throttle [23] is arranged in each branch [22] of the first manifold to reduce the risk of back-filling of the branches [22] of the first manifold [24]. |
