NUMBER:
5.1C/101
ISSUED:
November 1976
REVISED:
PRODUCT:
Centaur
MODEL(S):
Compressor, Mechanical Drive
Specifics:
Units with Constant Amp Throttle Control Z154
SUBJECT: CHANGE IN MAIN FUEL ACTUATOR (Z144)
CHECKOUT PROCEDURE
Type of Change:
Product Information
Recommended
Compliance:
Information
Purpose:
To provide information on revised temperature topping test and adjustment procedures.
GENERAL INFORMATION:
This change in procedure applies only to the static checkout of the Z144 topping system.
Early issues of Operation and Maintenance Instructions for Centaur compressor sets and mechan-
ical drive packages provided the instructions referenced and schematically illustrated in Figure 1,
for temperature topping test and adjustment. These instructions have since been revised (in May
1976) to those referenced and schematically illustrated in Figure 2.
The indicated steps (6 and 18) typically appear in Section 2 of compressor manuals, and in Section
5 of mechanical drive package manuals.
Users whose manuals now read as shown in Figure 2 need take no action for conformance with this
bulletin; the procedure is appropriate as it appears in the manual.

Users whose manuals read as shown in Figure 1 should substitute procedural steps 6 and 18 of
Figure 2 for the same steps (6 and 18) of Figure 1, in their manuals.
1.
Install a jumper from T9-5 (wire 567) to T9-9 (wire 571). This allows Z144 turn-on bias
to trigger Z144 N
gp
amplifier when testing in static state.
2.
Remove the jumper wire installed in step 6.

3.
Remove jumper between T9-5 and T9-2 (wires 567 and 168) at T9-2 and reinstall
from T9-5 to T9-9 (wire 567 to 571). This allows Z144 turn-on bias to trigger Z144
N
gp
amplifier when testing in static state.
4.
Restore jumper between T9-5 and T9-2 (wires 567 and 168), and remove jumper from
T9-5 to T9-9, installed in step 6.

Completion of this change, where necessary, will provide a better circuit for checkout of the tem-
perature topping function. Basically, the old procedure called for a jumper between the E and G
terminals on the Z144 control as the only requirement for properly triggering the amplifier. The new
procedure requires the removal of the jumper between 168 and 567 in addition to the E-G jumper.

A Team of Engineers asked for an internal combustion engine to use it in a designed car. Your role is to describe the operation sequence of different types of available engines, explain their mechanical efficiency, and deliver a detailed technical report to show your approach in solving and discussing the following tasks and issues.
You must follow the following steps to help the team:
STEP 1
Describe the operational sequence of four-stroke spark ignition and four-stroke compression ignition engines with the aid of sketches by constructing simple sketch representing the operation and plotting the P-V diagrams for each process during the cycle to show the following:
The input and output heat and net output work
The expansion and compression strokes
The air-fuel mixture intake and exhaust gasses
The spark plug when it is in the active mode
The complete cycle of ideal Otto and Diesel cycles that shows the input and output heat and net output work.
STEP 2
Explain the mechanical…

What would an isometric of the oxygen piping system below look like, where
PSA GEN = Pressure Swing Adsorption Oxygen Generator (PSA)
COMPs = Compressors
POMPs = Pumps
HEAT = Heat Exchanger
PV = Flow Valves
ST TANK = Storage Tank
VENT = Vent
DR = Drains
PSV = Pressure Relief Valve
In addition, what would be the possible problems that would require flexibility correction by adding expansion joints, spring supports, anchors and brackets?

The Weather Monitor. Your South American expedition splits into two groups: one that stays at home base, and yours that goes off to
set up a sensor that will monitor precipitation, temperature, and sunlight through the upcoming winter. The sensor must link up to a
central communications system at base camp that simultaneously uploads the data from numerous sensors to a satellite. In order to
set up and calibrate the sensor, you will have to communicate with base camp to give them specific location information.
Unfortunately, the group's communication and navigation equipment has dwindled to walkie-talkies and a compass due to a river-raft
mishap, which means your group must not exceed the range of the walkie-talkies (3.0 miles). However, you do have a laser rangefinder
to help you measure distances as you navigate with the compass. After a few hours of hiking, you find the perfect plateau on which to
mount the sensor. You have carefully mapped your path from base camp around lakes and…

I would like to explore the possibility of using a lighting control system. There are times when office staff works long hours and researchers sometimes need to be in the building on nights and weekends. Often times they leave the lights on which increases my electricity costs. I would like to be able to program the lights on a schedule and if the staff needs to work outside that schedule they could request a change with our maintenance staff ahead of time. Could you please look into this and provide me with some potential options.

You are assigned as the head of the engineering team to work on selecting the right-sized blower that will go on your new line of hybrid vehicles.The fan circulates the warm air on the inside of the windshield to stop condensation of water vapor and allow for maximum visibility during wintertime (see images). You have been provided with some info. and are asked to pick from the bottom table, the right model number(s) that will satisfy the requirement. Your car is equipped with a fan blower setting that allow you to choose between speeds 0, 1,2 and 3. Variation of the convection heat transfer coefficient is dependent upon multiple factors, including the size and the blower configuration.You can only use the following parameters:
