Versions with petrol engines
A 4-2-1 type exhaust system has been adopted, which reduces the residual amount of exhaust gases in the engine cylinders due to the scavenging effect, and also promotes a high compression ratio. In addition, this type of exhaust system takes up less space on the vehicle.
Versions with diesel engines
A feature of the exhaust system of the SKYACHV-D 2.2 diesel engine is that, thanks to the use of an exhaust port in the cylinder head, the exhaust manifold has been eliminated.
