Abstract
A linearly aligned four-cylinder internal combustion engine system operated in a 1-3-4-2 sequence, comprising a cylinder head connected with a cylinder block wherein each cylinder has at least one exhaust port to discharge exhaust gasses via an exhaust gas discharge system, for which an exhaust gas pipe is connected at each exhaust port; wherein the exhaust gas pipes of the cylinders that merge in stages into a common exhaust gas pipe and the exhaust gas discharge system emerges outside of the cylinder head. Thus exhaust gas from consecutive ignitions in adjacent cylinders is separated for a distance throughout the engine head to reduce mutual influencing in adjacent cylinders with consecutive ignitions.
