<p>An 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 despersed 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).</p> |
