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 I4 DOHC engine
With the discontinuation of the Sierra in 1993 and the RS2000 in 1996, the I4 engine continued in more workaday applications, appearing in the Ford Galaxy MPV launched in 1995. By this time, a longer-stroked 2.3 litre 16-valve version of the engine was available alongside the original 2.0 which was still available in both 8-valve and 16-valve versions. This 2.3 litre unit also appeared in the Ford Scorpio and the Ford Transit van. The I4 remained the main petrol unit for the original Galaxy until its 2006 redesign.
