Shielded Air/Fuel Control EH120 pages

EH12 SHIELDED IGNITION SYSTEM
The EH12 ignition housing offers a shielded enclosure for the GS6, GS8 and GS12 igniters. This
ignition system provides highly accurate and extremely powerful inductive ignition, which when
tailored with the Gill range of ignition coils, produces spark durations
well in excess of any CDI ignition system. This power and
accuracy enable the GS6, GS8 and GS12 series to control
normally aspirated or turbo-charged engines, running on
Class 1, DIV 2
Groups C & D
natural gas, biogas, LPG and CNG in either lean burn
or Stoichiometric air/fuel ratios. The enclosure
provides header type connectors to enable
quick and simple installation. Designed
to be user-programmable via the
Windows® GUI,.
