Abstract
Abstract The invention relates to the structure of an internal combustion engine having a plurality of cylinder banks, and more particularly to the structure of an internal combustion engine for a vehicle suitable for use as an internal combustion engine of the V-shaped arrangement, and it is an object of the invention to provide a multi-cylinder internal combustion engine having two cylinder banks wherein the structure which incorporates a plurality of different types of valve operating mechanisms can be realized while enhancing the facility in assembling operation and the production efficiency. To this end, the internal combustion engine of the present invention comprises at least first and second cylinder banks (8B, 8A) each including a plurality of cylinders or a single cylinder, a first valve operating mechanism (10) provided for each of the cylinders of the first cylinder bank (8B) for operating an intake valve or an exhaust valve (2, 3) of the cylinder to open and close, and a second valve operating mechanism (9) having a valve operating characteristic different from that of the first valve operating mechanism (10) and provided for each of the cylinders of the second cylinder bank (8A) for operating an intake valve or an exhaust valve (2, 3) of the cylinder to open and close.
