Plastic internal combustion engine to be developed... again!

Plastic firm Solvay says it is taking a leading role in the development of a plastic internal combustion engine.

The Polimotor 2 is to be tested in a race car next year, to demonstrate advanced specialty polymer technologies in lightweighting through metal replacement. Engines are typically made of metal and are the single heaviest part in a car. The Polimotor 2 aims to develop an engine weighing 63-67kg, around 41kg less than today's standard production engine.

In Polimotor 2, Solvay will replace up to ten metal engine components using its high performing thermoplastic materials including the water pump, oil pump, water inlet / outlet, throttle body, fuel rail, cam sprockets among others.

The Polimotor 2, four-cylinder, double-overhead CAM engine will ultimately be installed in a Norma M-20 concept car in 2016 to compete at the racing of Lime Rock Park in the US.

Solvay contributed a major role toward the success of the first Polimotor engine, conceived in the early 1980s.
