 SPECIFICATIONS FOR VEHICLE EXHAUST REMOVAL SYSTEM - NO SMOKE 2
The intent of these specifications is to define a device, system, method, etc. (hereafter referred to as "system") that will reduce gaseous matter in the diesel exhaust generated by internal combustion engines and meet all applicable federal, state, and local standards. Apparatus-mounted does not require more than one system to fully protect your firefighters. For example, hanging hoses require firefighters to inhale the toxic gases when hooking up the hose.
SYSTEM OPERATION
The system shall reduce gaseous matter from the exhaust for an adjustable time period of 10 to 99 seconds after the vehicle starts. This is to provide ample time to start the vehicle and move away from the building. The time of system operation shall be easily set by a mechanic or service person with common tools.
The system shall also reduce gaseous matter from the exhaust whenever the vehicle is in reverse gear. After the vehicle's transmission is shifted out of reverse gear the system will continue to operate for the pre-set time period. This will provide ample time to back the vehicle into the building and shut it off.
The system shall be completely automatic, not requiring action by any personnel at any time, with the exception of "normal maintenance." However, a manual override option is available to allow operation for service or special purposes.
Normal functioning of the system is in no way detrimental to the operation of the vehicle. Further, the system shall protect the engine by automatically preventing itself from activating when back pressure exceeds 1.8 PSI. At 1.5 PSI an indicator light on the cab dash shows that the system needs servicing by an authorized Ward Diesel technician.
SYSTEM COMPONENTS
The system shall consist of a ceramic substrate, a diverter unit and an electronic control module, all of which are completely self-contained on the vehicle. Therefore the system may be operated at any time, regardless of the vehicle's location.
The substrate shall be made of a porous ceramic material with proprietary wash coat measuring 11.25 inches in diameter and 6 inches long, designed and manufactured specifically to reduce gaseous matter from diesel exhaust. The substrate is encased in stainless steel with a high-temperature cushioning material between the ceramic and stainless steel. The substrate is installed using four tie rods with hex nuts so that it can be removed with no special tools.
The diverter unit shall be installed in the existing exhaust pipe and shall direct the engine exhaust either through the substrate or through the muffler. The diverter is operated by a double acting air cylinder controlled by an electrically activated, four-way, single solenoid valve.
The electronic control module, which drives the diverter unit, features a circuit board housed in a small (5" x 6" x 8”) metal enclosure. This is conveniently mounted for access. The circuit board holds the timer control where the duration of the filter cycle is set. The board also features a series of LED lights that monitor each function of the system. An hour meter mounted in the electronic control module shows the number of hours that the substrate has been in use.
System installation shall be completed and tested at the customer's location, or the provider's location as determined in the original purchase order agreement. Additionally, the provider will explain the operation and maintenance of the system to the personnel who will be responsible for routine maintenance.
A written warranty will be provided to ensure that the system is free from defects in materials and workmanship for a period of one (1) year from the date of installation.
