engine bay insulation

  • Engine Bay Insulation for Military Vehicles

    Military Land SystemsEngine bay insulation for military vehicles keeps noise and heat in the engine bay from reaching the passenger compartment. The diesel engines that power military land systems run loud and hot, raising concerns about solider health and safety. Warfighters need to be able to hear each other above engine sounds, and a vehicle where the air conditioning runs full-blast is less fuel-efficient. Hotter vehicles also have stronger heat signatures, making them more susceptible to thermal detection by hostile forces.

    Thermal-acoustic insulation is important, but manufacturers of military vehicles also need to protect on-board electronics and instruments from sound-induced vibrations. Otherwise, these noise disturbances can shorten equipment life through component failure. Resistance to flash and fire supports the mission, too. Engine bay insulation must also resist oil and automotive chemicals, withstand washdowns with water and detergents, and support cost-effective fabrication. Continue reading

  • Engine Bay Insulation for Mobile Equipment

    Engine Bay InsulationEngine bay insulation for mobile equipment keeps heat and noise in the engine compartment from reaching the cab interior. The diesel engines that power mobile equipment run hot and loud, which raises concerns about occupant comfort, health, and safety. Mobile equipment manufacturers also need to protect cabin components such as instruments from sound-induced vibrations. For a complete engine bay solution, Elasto Proxy makes thermal-acoustic insulation that can also dampen vibrations.

    With mobile equipment, the cab where the operator sits is right next to the engine compartment. Unless adequate engine bay insulation is attached to the firewall, heat and sound from the engine will spread to the cabin. Cab insulation helps, but you need a complete solution. Elasto Proxy makes firewall insulation, and also fabricates insulation that’s installed under the cabin floor. This thermal-acoustic insulation is important in mobile equipment designs where the cab is directly above the engine compartment. Continue reading

    When a manufacturer of military vehicles isn’t satisfied with a product design, more than just the bottom line is at stake. For coalition forces in Iraq and Afghanistan, armored fighting vehicles provide mission-critical force protection. Most military observers focus on features like the steel plating and the guns, but this type of vehicle won’t deploy anywhere without a big diesel engine under the hood.

    In military vehicles such as armored personnel carriers, diesel engines run hot and loud. Without engine bay insulation, this heat and noise could put both the powerplant and military personnel at risk. Thermal acoustic insulation must also meet flame, smoke, and toxicity (FST) standards. In addition, engine bay insulation must withstand vehicle wash-downs and exposure to detergents and other cleaning chemicals. Continue reading
