  • Page 6: Introduction

    Introduction Introduction Introduction Introduction Introduction Congratulations on purchasing the Ultimate Bar Graph Engine Analyzer (UBG), one of the most sophisticated diagnostic tools available in general aviation. You can learn the basic operation of the UBG in the first few minutes of hands-on operation. Although the UBG is simple to operate, its capabilities are numerous. The UBG is shipped from the factory with all of the programmed limits turned off.

  • Page 7: Step Switch

    The Bar Graph Display allows visual comparison of EGTs and CHTs at a glance. It also allows you to see where the EGTs and CHTs are operating in their normal operating range (i.e., high EGTs will be displayed with many bars lit in a column and low EGTs will be displayed with few bars lit in a column).

  • Page 8: Displaying Other Temperatures And/Or Functions Digitally

    Note: An aircraft engine can not be shock cooled when cylinder head temperatures are below 300'F. For this reason, the UBG-16 will display "-00" when the CHT drops below 300'F. A Shock Cooling Limit and the cylinder to be monitored for shock cooling are programmable (see “Programming the Shock Cooling Limit and Cylinder”).

    It is recommended that the EGT columns be normalized while operating your aircraft in normal cruise flight, with the engine leaned. When operating in the Normalized Mode only Normalized Mode only Normalized Mode only Normalized Mode only Normalized Mode only, the EGT bars may be normalized on the UBG display by performing the following steps: 1.

    Next, slowly lean your engine by pulling the mixture out a very small amount. When the increase in temperature slows to less than one degree per second, once again lean the engine a very small amount. The slower you lean, the more accurate the results will be. When any cylinder reaches its peak (hottest) EGT and starts to decrease in temperature, the digital display will blink the word “PEAK”...

    Programming the Shock Cooling Limit and Cylinder: Programming the Shock Cooling Limit and Cylinder: Programming the Shock Cooling Limit and Cylinder: Programming the Shock Cooling Limit and Cylinder: Programming the Shock Cooling Limit and Cylinder: Sudden cooling of the CHT (known as shock cooling) is a common problem in some engines. In others, it is rare. Shock cooling an engine can result in bent pushrods due to exhaust valves sticking, burned valves, spark plug fouling, broken piston rings, cracked cylinders at the spark plug and valve ports and warped exhaust valves.

  • Page 22: Power-Up Programming

    Your engine’s EGTs will vary at different power, altitude and mixture settings. To further enhance the UBG’s ability to detect a problem, select the EGT Difference (“DIFF”) on the UBG’s digital display and note the EGT Difference during climb, cruise and descent. Set the EGT Differential Limit for 30’F higher than the observed maximum difference.

    Fuel/Air Profile Fuel/Air Profile Fuel/Air Profile Fuel/Air Profile Fuel/Air Profile When viewing "Profile" the bar graph display shows the fuel/air distribution for your engine. This display is intended as a technical view of how your engine is operating. Once you know the fuel/air distribution for your engine, its easier to make logical decisions on how to run your engine (rich of peak, at peak, lean of peak, lean on climb, etc.).
