Renault 8B

The Renault 8 Bd was a liquid-cooled V-8 aero engine, of 190 hp.

Construction used separate cast iron blocks for each pair of cylinders, mounted on a light alloy crankcase. Vee angle was 50°. Each bank had a single overhead camshaft, shaft-driven through bevel gears. Single dual-choke updraught Zenith carburettor. Twin spark ignition, through 4 magnetos. Crankshaft was a flat plane with three bearings and four throws, each pair of cylinders sharing a master-slave rod onto the same crankpin.
