The oxygen sensor An automotive oxygen sensor, also known as an O2 sensor, lambda probe, lambda sensor, lambda sonda or EGO (exhaust gas oxygen) sensor, is a small sensor inserted into the exhaust system of a petrol engine to measure the concentration of oxygen remaining in the exhaust gas to allow an electronic control unit (ECU) to control the efficiency of the combustion process in the engine. In modern engines catalytic converters are controlled electronically by exhaust oxygen sensor. When it comes down to attain the lowest emissions, electronic control over these chemical processes is a must. Oxidation and Deoxidation within the catalytic converter CO + (1/2)O2 - CO2 CnH(2n+2) + O2 - CO2 + H2O NOx + CO - CO2 + N2 There is many other chemical reactions take place. For over 30 years the most effective way to reduce the emission of harmful gases and materials to clean and neutralize the combustion products subsequently has been to purify the exhaust gas with one or more catalytic converters fitted on the vehicle's exhaust system. The theory described with chemical equation: Ideal perfect combustion CnH(2n+2) + O2 - CO2 + H2O Realistic combustion CnH2(n+2) + O2 - C + H2 + O2 + CO + CnH(2n+2) HC Since the gas is polluted N2 + O2 NOx Pollution, additives S + O2 SO2 + H2O + H2SO3 The carbon-oxide, nitro-oxides, hydrocarbons and the sulfuric-acids are deemed harmful, therefore their emission level is restricted by emission regulations in most of the countries. Engine's efficiency and the amount of harmful emissions varies on several factors are related to the combustion taking place in the chambers. An Otto-engine's efficiency is not better that 30 up to 45 %. Are you in need of custom size cat?

Your Fleetwood Pace Arrow powered by GM 8.1L V8 - Gas free flow converter will fit to factory piping. Magnum free flow catalysts feature engine specific gas restriction and vehicle specific inlet / outlet diameter. As with HP, the current increase isn't anything incredible, but the massive gains tend to improve as the rest of the car's performance level. Magnum Fleetwood Pace Arrow powered by GM 8.1L V8 - Gas free flow cat converters increase this torque as well as the power capability throughout the engine RPM range. Torque in general, the power you feel in the seat while driving. It is generally reasonable to assume that cheap converters are of lower quality, but that doesn't mean that the most expensive catalyst converters are the best. There are huge differences in quality between brands, which results from the different raw materials that are used, manufacturing technology, coating materials, and numerous other factors. Contrary to the popular belief, catalytic converters are not commodities.
