Shift in the Demand Curve. A shift in the demand curve occurs when the whole demand curve moves to the right or left. For example, an increase in income would mean people can afford to buy more widgets even at the same price.
Once they fail they can do massive damage like I've described above. Clogged catalytic converters cause the engine to stop running all together, or at the very least you would notice that the engine would no longer rev or accelerate the vehicle (lack of power). Customer: replied 7 years ago.
The purpose of any catalytic converter is to reduce harmful emissions from the exhaust of a properly tuned combustion engine. It accomplishes this through a combination of heat and aprecious metal catalyst that causes the harmful emissions to either oxidize or reduce to safe elements in the exhaust flow.irst, the carbon deposits prevent the catalytic converter from reducing harmful emission in the exhaust flow. And second, the carbon deposits clog the pores in the ceramic catalyst and block exhaust flow, increasing backpressure and causing heat and exhaust to back up into the engine compartment.
