Procedures of removal and installation of components of system of production of the fulfilled gases are completely similar 4.2 l described for carburetor engines.
Models with the engine of 4.2 l of EFI (since 1992 вып.)
The design of system of production of the fulfilled gases of models of 4.2 l of EFI generally differs from presented on illustrations, except for installation between a reception pipe and the exhaust silencer of the catalytic converter a little.
The catalytic converter is a component of system of decrease in toxicity of the fulfilled gases and represents the ceramic core placed in a metal casing covered with a layer of platinum, палладиума and rhodium. Passing through the converter, hydrocarbonic connections containing in fulfilled gases, oxides of nitrogen (NOH) and carbon monooxide (WITH) will be transformed as a result of chemical reactions to carbon dioxide, nitrogen and water.
In normal conditions the catalytic converter does not need regular service or replacement. However, it can be put out of action or irreversible is polluted as a result of influence of excessive temperatures of the fulfilled gases, hit of crude fuel or when using etilirovanny fuel (with the high content of lead). In order to avoid casual filling by etilirovanny fuel the fuel tank of models of 4.2 l of EFI is equipped with a jellied mouth of smaller diameter which besides is equipped with a podpruzhinenny door trap. The ceramic core also can be damaged as a result of blows and strong pushes. At an overheat or a zasvintsovyvaniye of the core there is a violation of its passableness that conducts to decrease in section of a final path through passage, increase of resistance to production of gases and decrease, thereby, overall performance of the engine.
In order to avoid damage of the catalytic converter it is necessary to observe rules:
