About Gill Instruments Product Overview With headquarters in Lymington, UK, Gill Instruments Ltd supply ignition and air/fuel ratio control systems for stationary and mobile gas engines. We have over twenty years of experience in the industry, supplying SMEs and OEMs worldwide. The Gill Engine Control range is flexible enough to offer cost-effective solutions for almost any engine configuration from 1 to 12 cylinders. Our core product range encompasses ignition and air/fuel control systems, as shown in the diagram below. All of our engine control products have been developed using the very latest...

Introduction to Inductive Ignition Technology Gill ignition systems use inductive technology to ignite the air/fuel mixture. Inductive coils are generally more efficient than capacitor discharge coils as they provide longer spark duration, ensuring complete combustion, especially on lean burn and turbo charged engines. An inductive ignition coil provides just enough energy to cross the spark gap; the remaining energy from the ignition coil is used to maintain the spark. Capacitor discharge coils release almost all their energy instantaneously, therefore considerably reducing the amount of energy...

Ignition Modules EH12 Shielded Industrial Ignition System Gill ignition modules are designed to control normally aspirated, turbocharged and lean-burn engines running on LPG, natural gas and bio gas. The GS range utilises the latest inductive ignition technology to provide a powerful spark with long duration, enabling complete combustion of low calorific value fuels as well as lean air/fuel mixtures. The Gill EH12 is a CSA® approved shielded enclosure, housing the GS6, GS8 or GS12 ignition modules. This unit allows easy internal wiring termination negating the need for additional junction boxes....

Inductive Ignition Coils Pickup Conversion Kits Gill Ignition Coils are available in several electrical and mechanical configurations. We have a frame mount ignition coil (FM40), designed for small petrol and gas engine applications, surface mount ignition coils (SM60 and CY90) with a higher energy output designed for gas engines and integral coils (IC6 and IC12). Convert your Altronic® III and Altronic® V ignition systems to a fully programmable advanced Gill ignition system. Kits are available to allow these units to use the existing housings and some gear parts and substitute a magnetic pick-up...

Air/Fuel Ratio Control AF120 Air/Fuel Control Module One Controller for Lean Burn and Stoichiometric Engines The AF120 control module can be used within a variety of control systems. In the carburettor bypass configuration the Gill AF120 fuel valve can be utilised. Alternatively the module can be used to control fuel pressure regulator systems and systems requiring turbo waste gate control. The Gill air/fuel ratio control system provides cost effective emissions control for gaseous fuelled engines used in demanding industrial applications. The system is designed to accurately control the air/fuel...

IDU10 Digital Display Compact Display for Air/Fuel or Ignition Control The IDU10 Display is designed for use with Gill ignition and air/fuel control systems (factory configured for the application type). The unit is available in both panel-mount and surface-mount configurations, with a robust case sealed to IP65 and clear, intuitive menu structure. Ignition Control Air/Fuel Control The IDU10 Display is compatible with Gill GS8 and GS12 Ignition Modules and can be used as a remote unit with the EH12 shielded protective enclosure. The unit offers users comprehensive display and control functions...
