Learn how polymer engines can change the future of the automotive sector

In the automotive industry, many professionals still “turn up their noses” when it comes to a polymer engine – it was not much different when aluminium engine structures came onto the scene. After all, it is quite true that the idea of ​​an engine built from plastic alloys may seem rather unusual.

What cannot go unnoticed, however, is that this type of transformation iceland phone number list comes from a much more significant movement, which is the constant need of the industry to produce cars that consume less, are more efficient and offer more safety and comfort to users.

In this context, high-performance polymers already represent an innovation capable of having a significant impact on these indicators, since these alloys have greater mechanical, thermal and chemical resistance. This means that the arrival of these components in engines – the most critical and delicate part of cars – is nothing more than a natural reflection of this search for performance and sustainability.

Polymer engine: more sustainability and performance
Although it has been present in cars for several decades, plastic has always maintained a sort of “safety distance” from the engine. In practice, issues such as the lack of resistance to high temperatures and the risk of contamination by contact with chemicals such as oils and lubricants have always been major obstacles for the polymer engine.

However, all the technological advances to strengthen and ensure greater flexibility in the application of polymer alloys help plastic to overcome this final frontier. Today it appears applied in aggregate systems, such as intake manifolds and resonance boxes, in fuel galleries and even in the crankcase – all components in which the requirements for resistance to vibrations, impacts, temperatures and chemical interactions are quite intense.

In addition, the increasing use of plastic in engines is also in line with the constant quest to reduce the overall weight of vehicles. After all, plastic is much lighter and reduces fuel consumption. In this context, polymer-based alloys are increasingly being used in the automotive industry, as they also offer immunity to corrosion, better sound insulation and, of course, greater freedom of design.

In cylinder heads, for example, it is already possible to find plastic in the upper part of the composition, and it is even used in the manufacture of supports for ignition coils. Inside the engine, it is present in various components of the most varied sizes. It is enough to note that, although it is used in the intake manifold, polymers are also present in the covers of the camshaft sensors, in the coil support and in the covers of the timing belts.
