Next Generation of High Heat Mounting Applications: Silicone Load Bearing Hydraulic Mount

In today's automotive market there is a trend of increasing under-hood temperatures. There are package space reductions and engine innovations which contribute to these temperature increases. This trend directly affects heat-sensitive components such as engine mounts, which are traditionally made with natural rubber. Paulstra now has hydraulic engine mount technology which takes the next step in heat resistance. This technology was developed in response to BMW's desire to place a new high performance engine on a common chassis. Instead of increasing chassis complexity to relocate the engine mount away from heat sources, an engine mount was developed which could resist temperatures up to 200°C. This paper describes the design, performance, and considerations of this new technology in engine mounting. This is the first silicone hydraulic engine mount to be manufactured in North America.
