CONSTRUCTION
A scavenging pump assembly is adopted that forcibly returns oil from the cylinder head sub-assemblies to the oil pan sub-assembly. Even during cornering that exceeds 1G, oil level fluctuation in the oil pan sub-assembly is controlled to ensure a stable oil supply.
The scavenging pump assembly is a belt driven 2 rotor pump, both rotors operate in parallel, one for the left bank and one for the right bank. A compact high efficiency cycloid type rotor which has 4 lobes on the inner rotor and 5 on the outer rotor is used.
