The Cléon-Alu engine, also known under the code "A engine" or "A-Type" (A for aluminium) is an automotive gasoline internal combustion engine, developed and produced by Renault in 1960. A four-stroke inline four-cylinder design with aluminium-alloy block and cylinder head, it was water cooled, with a five main bearing crankshaft and a side-mounted chain-driven camshaft operating eight overhead valves via pushrods and rockers. It made its debut appearance on the Renault 16.^[1][2]
