Internal combustion engine and vehicle comprising the internal combustion engine

摘要

An intake system 1 of a charged internal combustion engine comprising an intake manifold 7 in communication with at least one combustion chamber 2, where the combustion chamber comprises an intake port 6 and an exhaust port 11, a fuel injection valve 14 with a fuel injection tip 15 within the intake manifold and a baffle 16 in the intake manifold or the intake port to direct the gas or fuel. The baffle may be positioned downstream or upstream from the fuel injection valve tip to produce a reduction in pre-ignition events in the cylinder. The baffle may also be positioned radially at an inner side of the intake manifold, cylinder head or intake port. The baffle can be fixed or is adjustable to occupy a variable cross-sectional area of the intake manifold or intake port, where the baffle may be rotatable. Preferably the baffle comprises a plate with at least one through hole.
