Polimotor 2: polymer composite car engine

Four-cylinder all composite engine, Polimotor2 proves the capabilities of composites to replace metals in the variety of applications. The developmental engine is planned to be installed in a race car that will compete at the Petit Le Mans at the Road Atlanta course later this year.

The project initiator is Matti Holtzberg, an enthusiast of plastic car engines and the president of American Composite Castings, LLC. Glass fibers used for car engine are produced by AGY Holding Corp.

“This program will provide a path for auto makers to reduce the weight of their engines, thereby decreasing their fuel consumption and CO2 emissions which is one global challenge in the automotive market,” said Iain Montgomery, Director of New Business Development at AGY.

Matti Holtzberg has been trying to prove the capability of composites to replace conventional metal parts in car engines for over 30 years. The first version of the composite engine was designed by the inventor in the mid 1980’s.

Holtzberg managed to get ten patents for composite engine parts, and their methods of production. The second version, Polimotor 2 engine, uses the latest technologies available in composite casting, building upon the initial successful development of the original Polimotor engine block.

The final engine will reportedly weigh around 64 kg., which would be 41 kg. less than a similar metal engine. The first generation called Polimotor was successfully used in race cars over two seasons and weighed 76 kg. Polimotor 2 block of the engine was displayed at AGY’s stand at the Paris JEC Show in March.
