When the Converter is Damaged...

		Partial Melting of the Unit (Converter)
	Errors in petrol consistency will result in the exhaust containing petrol, and hence lead to overheating of the unit. The Monolith begins to partially melt.
		Inconsistencies in petrol mixtures, or a malfunction of the ignition system lead to extraordinary heat development in the Converter.
	Damaging the Monolith due to ground contact, resulting in deformation.

Converter damage schemes

Decreasing catalysing abilities during the transformation of exhaust may be due to thermal degeneration of the system or wear on the motor and its aggregates. Leaking fuel or oil droplets may precipitate the partial melting of the unit.

Influences of wear, tear and pollution

In essence there are two influencing factors that reduce catalysing properties. The first is the chemical pollution of the catalysing metal elements, by petrol (Lead, Magnesium and other elements). Secondly it will be reduced due to thermal degeneration of the active elements.

Melting of the Monolith

The melting point of the ceramic body that carries the unit, is set way above 1000 Celsius. The essential cause of this melting effect is the malfunctioning of the ignition system, resulting in petrol being incinerated in the catalytic unit, rather than in the engine cylinder.
