Automotive Test Equipment

Huff Technologies Inc. designs and builds various engine and component testing and inspections systems. Today's market demands tight quality control and 100% inspection of engines, components, and accessories.


Field failures and low quality components are costly to repair and devastating to a company's reputation. Huff Technologies uses custom PC/PLC Data acquisition and control solutions, in-house software development capabilities married to various sensors, systems, and components to provide creative solutions to your testing and inspection needs.


Four Stroke Engine Test Stand

Problem: A customer producing 2 cylinder four stroke engines needed a fast, accurate way to test its engines on the assembly line. The system must be versatile enough to test different engines and save the data for records purposes. 4stroke_test_stand

Solution: Huff Technologies Inc. designed and produced three systems which allowed the customer to build a test profile for each motor type. The engine barcode is automatically scanned and the proper test profile is run for that type of motor. The system tests for fuel flow, starter amps, alternator amps, alternator volts, oil pressure, rpm, case pressures, water pump rotation, and performs a vibration analysis. All parameters must be within set limits or the engine is rejected. All data is stored under the engine serial number for record keeping purposes.

V-Twin Production Engine Dynamometer

Problem: Customer was breaking in motors on the assembly line but testing motors off line on facility dynamometers. This process was time consuming and expensive.


Solution: Huff Technologies Inc. designed and built a production line system to break-in, quality test, and then run a dynamometer test on the motors. The v-twin_prod_eng_dynamsystem runs a customer specified test profile to break-in and test the motors. Fourteen (14) separate systems and functions are tested during the break-in and dyno test. At the end of the break-in period, a sweep type dyno test is preformed and six pass/fail plots are generated. All data is stored for quality control and records purposes.


Wiper Motor Test System

Problem: Customer needed a final quality test system for its rebuilt wiper motors. With over 500 different motors, the system had to be versatile and simple to operate.


wiper_motorSolution: Huff Technologies Inc. designed and built a computer controlled test system which allowed the customer to run a different test profile for each type of motor. The motor barcode is scanned and a test profile for that motor is loaded. By engaging a start button, the test profile is run which checks for proper motor speed , amps, voltage fluctuations, all against a variable load. The system is then capable of printing a QC Pass Barcode and serial number to be placed on the motor.


Robotic Test Cell

This robotic test cell automatically inspects fuel pumps. The pumps are tested under wet conditions for proper pressures, flows, and amp draws at various voltages. Passed pumps are sent to one of three purge stations where the fluid is blown out of the running pump. A failed pump is discarded.

When in automatic mode, the robotic arm transports the pumps from a staging conveyor to one of three inspection stations. If the test system indicated a passed pump the robot removes it and places it into one of three purge stations. A failed pump is removed and placed into a discard bin. Once the pump is purged, the robot removes it from the purge station and places it on an exit conveyor.


Rear Differential Assembly

This system assembles a variety of rear differentials for trucks. An aluminum pallet with a nylon fixture transports a base part along the line during assembly. The pallet automatically stops at the correct position where the parts for a particular assembly are made available.

The current part being assembled is selected by touch-screen. The touch-screen allows the operator to open part bins manually or using a barcode scanner for resupply, to manually open bins for assembly, to modify the "recipe" for an assembly, and to schedule the machine's activity.

After assembly, the differential is inspected using a vision system and probe to determine if all parts are present. Based upon the results of this inspection the assembly is either passed or rejected, and the pallet is recycled for use with another assembly.
