The Renault 8G was a family of French liquid-cooled V-8 aero engines of the World War I era that produced from 140 hp (100 kW) to 190 hp (140 kW).
Design and development
Construction used separate cast iron blocks for each pair of cylinders, mounted on a light-alloy crankcase with an included vee angle of 50 degrees. Each bank had a single overhead camshaft, shaft-driven through bevel gears. It was equipped with a single dual-choke updraught Zenith carburettor, and twin spark ignition through four magnetos. The crankshaft was a flat plane with three bearings and four throws, each pair of cylinders sharing a master-slave connecting rod onto the same crankpin.
