Plastic automotive engine
Version one was based on Ford's 2.3-liter Pinto engine and weighed (vs. for its cast iron counterpart). It was designed to produce at 9200 rpm. It was composed of metal cylinder sleeves, metal combustion chamber tops, metal piston crowns, bearings, valves and seats, and a stock 2.3L Pinto crankshaft. Nearly everything else in the engine, including the block, rods and piston skirts, were made of glass reinforced Polyamide-imide thermoplastic resins manufactured at the time by Amoco Chemicals Co. The engine was never installed in a vehicle.
Ford Pinto engine
The Pinto engine was available in five displacements: , earlier , later , and the .Later 1998cc. Due to emission requirements, it was phased out towards the end of the 1980s to be replaced by the CVH engine and DOHC engine, the latter being (contrary to popular belief) a completely new design and not a twin-cam development of the Pinto unit. The 16-valve version of the Ford DOHC unit is still used on the Ford Transit. The only DOHC direct derivative of Pinto engine is the Cosworth YB 16-valve engine, powering Ford Sierra and Ford Escort RS Cosworth variants.
