Can a lean burn engine work with a 3 way catalytic converter?

Can a lean burn engine work with a 3 way catalytic converter?

Lean-burn engines do not work well with modern 3-way catalytic converter —which require a pollutant balance at the exhaust port so they can carry out oxidation and reduction reactions—so most modern engines tend to cruise and coastdown at or near the stoichiometric point .

Can a lean burn system change fuel economy?

A slight change in fuel economy would only be noticed if the Lean Burn system was in excellent working condition (if any change was seen at all). The electronic ignition paves the way for some special modifications such as Super Six carb rejetting, performance ignition systems like MSD, and customized timing advance curves.

Can a slant six engine be converted to lean burn?

This article outlines the Chrysler Lean Burn “conversion” to the earlier electronic ignition, or better stated as Lean Burn system removal from Mopar Slant Six engines (170 , 198 , 225). This article is also useful when converting from points to Mopar’s factory style electronic ignition (EI) or orange box (ECU).

Can a lean burn system be replaced with solid state ignition?

Removing the Lean Burn system and replacing it with solid state electronic ignition can still produce excellent results on pollution and emissions tests. A slight change in fuel economy would only be noticed if the Lean Burn system was in excellent working condition (if any change was seen at all).

How did the lean burn engine system work?

An early computerized spark-advance control system, Lean-Burn attempted to make the engine cleaner from within, rather than simply bolting on cleaners (like catalytic converters) after the fact. The system consisted of three parts: the carburetor, the spark-control computer, and a group of eight external sensors.

How to convert lean burn computer to Chrysler?

Connect the new wiring harness to the negative lead per the wiring diagram. Connect the 12v+ lead from the new wiring to a source of power which is only on with the key turned to run. If removing the Lean Burn computer is desired, the positive power to the coil should be wired using the ballast resistor diagram.
