• Converter, Model E, Silicone, Blue Spring

The IMPCO Model E Series is a two-stage converter/regulator. It is engine coolant heated to assist liquid fuel vaporization.  Diagnostic test ports are standard for both the primary and secondary pressure chambers, and a choice of diaphragm materials is available. The Model E Series converter/regulators are renewable with the appropriate repair kits.

The Model E Series provides a negative outlet pressure, with two pressures available. The only difference between the standard and the optional unit is the secondary outlet spring. The standard model EB utilizes a blue spring which supplies fuel at -1.5" WC, while the optional EO model uses an orange spring (-0.5" WC). These optional pressures can be used to fine tune special engine applications. The orange spring makes a good choice for cold weather start-ups due to the lower negative "give-up," however, it will also provide for richer fuel mixtures relative to the standard blue spring. A manual primer is standard on the Model E.

In industrial applications, the Model E converter/regulator is rated at 150 kW (200 hp) while in automotive applications it is rated at 242 kW (325 hp).  The difference in rating is due to the lower water flow expected in industrial engines.

A fuel lock is required upstream of the Model E converter/regulator.  Impco recommends mounting the Model E horizontally.
