Abstract

In a multi-cylinder internal combustion engine, the cylinders are disposed in two rows, the cylinders in one row being staggered with respect to the cylinders in the other row and the longitudinal axes of the cylinders in the first row being disposed at an angle to the longitudinal axes of the cylinders in the other row. The outlet valves are located close to the plane of symmetry between the rows of cylinders whereas the inlet valves are located out of this plane. All of the outlet valves of both rows of cylinders are provided with a common centrally located camshaft whereas the inlet valves of each row of cylinders is provided with a dedicated sidelocated camshaft for each row.
