copper-asbestos washer, and then secured by a cross-shaped clamp which was bolted to the crankcase with four long studs. Airflow for cooling the cylinders was generated with a fan driven from the rear end of the crankshaft. The fan was blowing air into the sheet metal enclosed chamber between the two rows of cylinders, which then left the enclosure through the narrow spaces between the cylinders, passing through the cylinder's cooling-fins.

combustion chamber, with the inlet valve situated below the exhaust valve. The inlet valve was operated directly from the camshaft via a tappet, whereas the exhaust valve was operated via a push rod and a rocker lever. The propeller was mounted directly on the camshaft, which was driven from the crankshaft via reduction gearing consisting of spur gears.

A single camshaft was situated between the two rows of cylinders and operates the inlet and exhaust valves of both cylinder rows, with each valve operated by a separate cam on the camshaft. The inlet and exhaust valves sat vertically opposed in a lateral pocket of the cylinder head on the side of the

The
Renault 100 hp V-12 engine was development from an earlier 90 hp Renault V-12. The main change was the increased bore size of 96 mm instead of 90 mm in the 90 hp engine. Otherwise the general design of the engine was left relatively unchanged, and like its predecessor its

The V-12 engine had its two rows of cylinders angled at 60 degree to each other and had a cylinder bore of 96 mm and a stroke of 140 mm. The cylinders and cylinder heads were separate cast-iron pieces with cast fins for air-cooling. The cylinder head was tightened to the cylinder with a

A dual carburetor was fitted on one side of the crankcase, with each barrel of the carburetor feeding one cylinder row. Ignition was supplied by two Bosch magnetos, with each magneto separately serving one cylinder row. The two magnetos were mounted transversely on the top of camshaft on the

The lower part of the crankcase served as an oil reservoir. A pressurized oil lubrication system was fed by a gear pump located on the lowest point of the crankcase. The oil pump was driven over a vertical shaft from the camshaft via helical gears. The crankshaft was supported by five plain

intermediate bearings and two outer ball bearings. Contrary to their V-8 predecessors, the V-12 engines had master-and-slave connecting rods instead of the side-by-side placement of the connecting rods on the same crank journal. This design was kept on the later
