Product of the Month: Fuel and Ignition Management System (FIMS)
For Gaseous-Fueled, Spark-Ignited Engines
The Fuel and Ignition Management System (FIMS) provides a low-pressure advanced engine management solution for gaseous-fueled, spark-ignited engines and is designed to meet tough exhaust emission control standards in the United States and across the world.
GAC provides two ways to manage control. The Air/Fuel Ratio Control (AFR) and Ignition Control Module (ICM) 200 Series together provide a low-cost solution to meet emissions standards. The AFR control creates a closed-loop fuel system when combined with five simple components:
• A digital precise stepper motor fuel control valve to adjust the flow of fuel into the system or into the static venturi mixer
• An electrically controlled throttle body valve or universal actuator to control the flow of the air/fuel mixture that enters the engine intake manifold based on engine speed and load
• An oxygen sensor that provides feedback to control how lean or rich the fuel mixture is
• A Manifold Absolute Pressure (MAP) sensor to determine engine load
The Ignition Control Module (ICM) Series controller is an intelligent electronic control module that is part of GAC’s distributor-less ignition system.
The complete-system approach results in a cost-effective solution that offers the greatest potential for improvements in both engine efficiency and exhaust emissions.
Application of the Month
Using GAC’s Fuel and Ignition Management System (FIMS), two Scania DC13 072A engines power a 270 KW generator supporting three water pumps in a Brazilian town.
The GAC ATB throttle body combined with the AFR speed controller is set to run these engines lean, saving fuel for the town.
This generator runs efficiently, consumes less fuel and produces more power.

Teaching the Next Generation About Manufacturing
“Can you teach me how to make that?“ asked one of the 30 students from the Duggan Academy in Springfield, Massachusetts, during a tour of GAC’s manufacturing floor this past December.
Part of a partnership between Duggan Academy and the Spark Photonics Foundation, the tour was meant to introduce the students to careers in manufacturing.
The 8th and 11th graders, who were all wearing safety glasses and doing their best to stay within the yellow ESD lines, gained a real-world look at how engine control systems, actuators and electronics are built. The students also learned how a manufacturing plant functions through stops at the quality, assembly and, automation areas as well as the machine shop.
The visit began with a welcome from the president, CEO and owner of GAC, Sean Collins.
“I am passionate about manufacturing and passionate about the next generation being a part of manufacturing,” Collins told the students. “Making things is important to our country.” He explained that GAC is a vertically integrated manufacturer which means they both design and build products. Collins told the students to remember: “The only person to get you where you want to go is you.”
During the tour, GAC’s manufacturing engineer manager asked the students, “Do you like to make money?” After receiving a loud “Yes!” the manager used their answer to explain how a manufacturing plant must make the best use of time and space, as this ultimately affects how much money the company makes.
The students asked some great questions such as, “How much does it cost to make a coil?” and, “What do you do when the part is bad?” after they heard about what quality means from the quality manager.
“It’s extremely important to get them out and let them see what it means to be in manufacturing, to get them thinking,” said Vanessa Mahoney of the Spark Photonics Foundation , which is an integrated photonics services firm based in Waltham, Massachusetts.
GAC volunteers also spoke with many enthusiastic 11th– and 12th-grade students at the Springfield High School of Science and Technology. According to the volunteers, the students were engaged and excited to learn about manufacturing in the Pioneer Valley.What’s New?

The GAC KT317WB-AFR
The GAC KT317WB-AFR, a ready-to-use lean burn adapter kit for FIMS500 AFR2XX Series controllers, determines how rich or lean an engine is running at any load. Performance and operational settings are adjusted and viewed in “real-time” using GAC’s SmartVU software. The adapter kit is available in 12 or 24 V DC and provides:
• An 0.8 to 1.5 λ range.
• A plug-and-play lean burn solution.
• An included wide-band Bosch LSU4.2 Sensor.
• An accurate wide-band to narrow band conversion.
Our office will reopen after the holiday season on January 3, 2023.
