Highway Vehicle Insulation

A particularly broad segment of the automotive industry is made up of on-highway vehicles, which consist of a variety of different types, such as RVs, special purpose vehicles, trailers and semi-trailers, buses, concrete mixers, and both heavy and medium-duty trucks.

The Different Industry Challenges for On-Highway Vehicles

There are a number of challenges facing on-highway vehicle manufacturers today Some of the  main issues in question are:

  • Meeting emissions targets
  • Protecting against high exhaust temperatures

At Firwin, we manufacture removable insulation blankets that can help address these challenges.

Meeting Emissions Targets

Manufacturers of on-highway vehicles continue to search for ways to reduce emissions as a result of continuing stringent governmental pollution control regulation. One of the main ways to do this is via catalytic filters. These filters function optimally at high exhaust temperature—sometimes upwards of 800° F (425° C). These high temperatures force the particles to circulate rapidly within the engine and exhaust components, which then causes them to be efficiently sifted out by catalytic filters.

Protecting Against High Exhaust Temperatures

While necessary to reduce emissions, this increase in exhaust temperatures can create some challenges for on-highway vehicles and their drivers. Cabin interiors can become too hot simply due to their proximity to the exhaust piping, which has a detrimental effect on personnel comfort. Additionally, heat-sensitive components and cables can malfunction when perpetually exposed to such high temperatures. Finding ways to increase exhaust temperatures while decreasing ambient heat is vital for long-term success in emissions reduction.

Meeting the challenges: How Insulation Can Help

Lack of proper insulation can result in the exhaust losing heat as it travels from the engine to the catalytic filter; this cooling can lead to suboptimal performance and a reduction of burn-off. Removable insulation blankets offer an excellent, cost-effective way to maintain engine exhaust temperatures, while at the same time reducing ambient heat and protecting personnel from hot exhaust components.
