Neon, and the Belvidere Assembly Plant where it is produced, continue Chrysler's commitment to setting the standard for environmental excellence.
Pollution prevention was incorporated into Neon's planning process. It was factored into decisions about the product, raw materials, distribution and manufacturing processes. The success of this proactive planning process has increased the awareness of its benefits in other platforms.
The environmental accomplishments of Neon and the Belvidere plant are a combination of continuing past pollution prevention efforts and incorporating new ones.
Recycling efforts on Neon are one area where considerable new ground has been achieved, said Susan Yester, Chrysler manager of vehicle recycling programs. "Plastics pose one of the most significant challenges in vehicle recycling," Yester explained. "We've attempted to address this in the Neon by labeling as many components as possible for recycling with SAE designations, and to design plastic components to increase their recyclability. This can include how the plastic parts are designed for disassembly when the vehicle is ready for scrapping, or engineering the components with as few plastic compounds as possible which may impede the recycling process. Examples of these include use of plastics which may not be shredded together, or other assembly pieces which may make disassembly difficult, such as plastic and metal combinations in components."
Yester also said that the Neon will use more components made from recycled materials than any other Chrysler product to date. In all, the Neon will hove recycled materials in more than 30 major assemblies or components.
"The ultimate goal is to recycle waste and scrap materials from the plant and reuse the material in other components." Yester said. "A technical problem the industry is facing in accomplishing this is that color-molded materials contaminate the recycling process. Right now, we are able to use this process on the Neon's plastic fascias."
Other major recycling features in Neon's manufacturing and vehicle design include:
A three-way catalytic converter provides primary control of exhaust emissions. Exhaust gases fed to the converter are produced by combustion of air and fuel maintained in stoichiometric proportions by electronic controls that use a heated oxygen sensor in the exhaust manifold.
Exhaust gas for EGR (exhaust gas recirculation) that minimizes NOx emissions produced during combustion is diverted through a passage off the #4 cylinder exhaust port to the EGR valve attached to the rear of the cylinder head. A steel tube delivers the metered exhaust flow to a thermally isolated connector at the inlet elbow of the intake manifold.
A charcoal-filled canister forward of the right front wheel collects vapor from the fuel tank to avoid releasing it to the atmosphere. A duty-cycle solenoid valve allows vapor to flow from the charcoal canister to the engine in proportion to engine mass air flow controlled by the PCM. The solenoid is rubber-isolated to reduce noise transmitted to the body.
Neon is the first Chrysler vehicle to have OBD II diagnostics, a technology-forcing requirement intended to ensure that emission control systems are functioning effectively for at least 100,000 miles (160,000 km). OBD II requires monitors for emission control systems to determine misfire, catalyst efficiency, fuel injection system operation, EGR flow, oxygen sensor heater operation and response, secondary air (aspirator) operation, and evaporative system operation. In addition, 50 sensors, switches and actuators are checked for rationality of action in addition to determining their presence or operation. Malfunctions in any of these areas turns on the CHECK ENGINE indicator light and records a diagnostic test code in the PCM memory that can be accessed via a scan tool. OBD II also requires a common data link connector for diagnosis of all on-board electronic systems and common vehicle diagnostic outputs for all required functions on all vehicles regardless of manufacturer. A generic scan tool must be able to read the required outputs. The only hardware addition needed to provide OBD II capabilities is a downstream oxygen sensor at the catalytic converter outlet which is used in monitoring catalyst efficiency. Other new functions are provided through additional diagnostic software.
