Improving On-Highway Vehicle Emissions and Safety with Insulation Blankets

Manufacturers of on-highway diesel trucks are looking for new methods to decrease truck emissions in response to the increasing consumer demand in green technology. Along with this, new EPA standards are increasingly restricting the amount of carbon monoxide, nitrogen oxide, hydrocarbons, and diesel particulate matter released by diesel engines.

Therefore, new engines have been released with redesigned configurations, selective catalytic reduction (SCR) systems, and modifications that allow for alternative sources of fuel.

For the majority of these emission-reducing exhaust systems to work, engines need to be kept at temperatures of 800 °F (425 °C) or more. Temperatures of this magnitude make sure that particles circulate quickly enough within the engine for catalytic filters to properly sift them out.

The utilization of insulation blankets is one of the most useful ways to maintain high engine temperatures. The blankets fit over the engine and reduce the chances of heat radiation from escaping, especially through the exhaust path.

Maximize Highway Vehicles’ Insulation Blankets Performance

To allow vehicles to reap the benefits of their insulation blankets, engineers in the trucking industry should consider the following recommendations:

  1. Make sure that the SCR systems are correctly insulated to maximize burnoff and performance. Without correct insulation, exhaust gases lose heat as they move along different components of the engine, pipes, and the exhaust system.
  2. Using insulation blankets, separate the engine from heat-sensitive cables and components. While keeping a high engine temperature will optimize particle filtration, the extreme heat may cause harm to other vehicle components. Removable insulation blankets are particularly beneficial in engine retrofit projects where the new engine would otherwise make nearby components vulnerable to harmful temperatures.
  3. Install insulation blankets over catalytic filters and exhaust piping. Doing this will make sure that the engine keeps high exhaust temperatures, which will maximize filter performance even in environments where there is cold weather.

Insulation blankets can be customized in many ways to adhere to each distinct system in which they are installed. Size, shape, and other physical characteristics can be customized to the environmental conditions that blankets may face.
