The wedge-shaped combustion chamber is used to provide high knock resistance and fuel efficiency of the engine. A vertical inlet port is used to increase the efficiency of the intake process. Installing fuel injectors in the cylinder head allows fuel to be delivered as close to the combustion chamber as possible. This prevents fuel from depositing on the intake port walls, which reduces CH emissions in the exhaust gases. The layout of the cooling jacket channels in the cylinder head has been optimized to increase cooling efficiency. In addition, an additional cooling channel appeared below the exhaust ports, which reduced the number of parts and made it possible to achieve weight reduction (pic. 2.6).
