Powertrain Systems

The Delphi Internally Insulated Catalytic Converter is a critical element of the system used to help reduce vehicle exhaust emissions. The catalyst element inside the converter is specifically designed to convert the harmful engine emissions into less harmful gasses. Unlike conventional catalytic converters, the internally insulated design has insulation inside the converter to keep the converter housing relatively cool.

Benefits

• Internally insulated construction provides improved durability, reduced heat rejection and lower noise
• Custom designs are available for specific applications to help achieve emissions performance objectives, to maximize engine performance and for engineered heat rejection
• Accelerated testing protocol enables faster time to market and lower implementation costs
  

Typical Applications

The Delphi Internally Insulated Catalytic Converter was developed for applications having high durability requirements. These conditions are often observed under high engine loads, high speed driving, or close-coupled positions. The Delphi Internally Insulated Catalytic Converter can be designed to meet specific customer requirements.

Performance Advantages

The Delphi Internally Insulated Catalytic Converter is designed to withstand very high temperatures and severe operating conditions. Because the insulation is packaged inside the converter, the outside surface temperatures are significantly lower, resulting in remarkably lower heat rejection into the surrounding components. The obsolescence of external heat shields eliminates exhaust system rattling and pinging and avoids corrosion issues raised by fibrous insulation material being exposed to the environment. The reduced converter temperatures also contribute to enhanced component durability.

The Delphi Advantage

Delphi is a global leader in engine management systems, including exhaust aftertreatment systems. Leveraging this expertise can help customers develop strategies to optimize fuel economy and exhaust emissions from air intake to the tailpipe. Delphi catalytic converters can play a significant role in helping create cost effective, environmentally friendly exhaust systems.

Since 1975, Delphi has produced more than 100 million catalytic converters. Delphi's exhaust emissions control technologies have helped prevent the release of an estimated 50 million tons of hydrocarbons, 245 million tons of carbon monoxide, and 60 million tons of oxides of nitrogen (NO_x) into the atmosphere.
