Manufacturers of on-highway diesel trucks are seeking new ways to reduce their products’ emissions in response to growing consumer interest in green technology. Additionally, new EPA standards increasingly tighten the amount of nitrogen oxide, hydrocarbons, carbon monoxide, and diesel particulate matter allowed to escape diesel engines. As a result, new engines have featured redesigned configurations, selective catalytic reduction (SCR) systems, and modifications that accommodate alternative fuel sources.

For many of these emission-reducing exhaust systems to work, engines must be kept at temperatures of 800°F (425°C) or greater. Temperatures of this magnitude ensure that particles circulate fast enough within the engine for catalytic filters to efficiently sift them out.

One of the most effective ways to maintain high engine temperatures is through the use of insulation blankets. These blankets fit over the engine and prevent heat radiation from escaping, particularly via the exhaust path.

Maximize Highway Vehicles’ Insulation Blankets Performance

To help vehicles get the most out of their insulation blankets, engineers in the trucking field should keep in mind:

  1. Ensure that the SCR systems are properly insulated to enhance performance and burnoff. Without proper insulation, exhaust gases lose heat as they travel along various pipes and components of the engine and exhaust system.
  2. Separate the engine from heat-sensitive cables and components using insulation blankets. Although maintaining a high engine temperature will optimize particle filtration, the extreme heat may damage other components within the vehicle. Removable insulation blankets especially benefit engine retrofitting projects, where the new engine would otherwise expose surrounding components to damaging temperatures.
  3. Install insulation blankets over exhaust piping and catalytic filters. Doing so will ensure that the engine maintains high exhaust temperatures, which will optimize filter performance even in cold-weather environments.

Insulation blankets can be endlessly customized to fit each unique system in which they’re installed—size, shape, and other physical properties can be tailored to the conditions that blankets may face in their installed environments.
