Alpha Competition Cel Fix O2 Lambda Sensor Mini Cat

Name: Alpha Competition Cel Fix O2 Lambda Sensor Mini Cat
Brand: Alpha Competition
SKU: AC-CEL-FIX
Price: 64.99 EUR
Availability: InStock

The Alpha Competition Cel Fix O2 Lambda Sensor Mini Cat, also sometimes referred to as a Cat Simulator or Cel Fix, is a device designed to address the Check Engine Light (CEL) that can illuminate after removing the catalytic converter (cat) from a vehicle’s exhaust system.

The catalytic converter plays a crucial role in reducing harmful emissions from a car’s exhaust. When a cat is removed, often in performance modifications referred to as “decatting,” the oxygen sensor (O2 sensor) downstream of the converter detects a change in the exhaust gas composition. This change triggers the CEL to illuminate, indicating a potential problem with the emissions system.

The Alpha Competition Cel Fix is a small, metallic device that screws onto the existing O2 sensor. It contains a miniature catalytic converter that mimics the function of the original cat, altering the exhaust gas signature to appear more normal to the O2 sensor. This can help to prevent the CEL from illuminating after decatting.

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.

Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content. Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
