day 33 -37

Day 33
1. Cooling, The answer i got from the document Jeff had us read was that the larger the radiator the cooler you can make the engine. you dont want to make an engine run too cool and you dont want it to run to hot, so you have to have the right size.

2. Detonation. When the fuel begins to burn, it will provide power. (duh) But if detonation happens too soon or to late, it will have an advers effect on your power if it happens to late, and can harm your engien if it happens to soon (pinging)

3. Contamination. Besides the recomended matenence intervals, could an oil change be determened?
By how often the engine runs. how long it runs and its duty cycle. most off shore applications and in boats, its commen that regardless how much the boat goes out that the owners will have the oil changed once a year.

4. Combustion air flow requirments. finishing the statement "Combstion airflow requirements will vary depending on the specific engine model and rateing. spicific air flow data for caterpillar engines is given in both..."  Volumetric and mass flow. at staderd reffernce conditions.

Day 34

1.The FCA is the Fuel Control Assembly and it regulates the fuel to the injectors.

2. High Preasure Fuel Warning

WARNING:

HIGH-PRESSURE FUEL LINES DELIVER DIESEL FUEL UNDER EXTREME PRESSURE FROM THE INJECTION PUMP TO THE FUEL INJECTORS. THIS MAY BE AS HIGH AS 23,200 PSI (1600 BAR). USE EXTREME CAUTION WHEN INSPECTING FOR HIGH-PRESSURE FUEL LEAKS. FUEL UNDER THIS AMOUNT OF PRESSURE CAN PENETRATE SKIN CAUSING PERSONAL INJURY OR DEATH. INSPECT FOR HIGH-PRESSURE FUEL LEAKS WITH A SHEET OF CARDBOARD. WEAR SAFETY GOGGLES AND ADEQUATE PROTECTIVE CLOTHING WHEN SERVICING FUEL SYSTEM

3. There are 2 Intake heaters for the Dodge 3500.

4. Vehical throws an Open code for all 6 injectors. meaning that more than likely the harness got torn off or disconected some how. the chance of all six going out at once and needing new injectors is slim. another possobility is the cam shaft position sensor is bad but did not show on this truck so that is still good.but if it did have a code then that could be why the truck is not starting.

5. Making the horn blow and wipers work with the scan tool is called "Bi-Differencal control"

Day 35

1. Scanning the Freightliner for codes came up with a barmetric preasure code that was shorted high.

2.(pic next) seeing the humps on the scope then seeing the longer one let me know that the longer signal was TDC for cylender #1

Day37

1. the 9 functions of oil. Lube, preasure wear control. cleaning, protection, cooloing, sealing, shock dampening, hydrolic action.

2.6 oil contaminits. Combustion biproduct, acid varnish, abrasives, fuel, coolent, soot, and enviermental contaminnts.

3. the 9 sets of data that must be included in oil analysis
Engine modle and Sn#
Miles/Hours of oil use
Miles/Hours since new or rebuild
Oil Used
Date Sample was colected
Engine Application
Amount of oil added since previous oil change
Any recent engine matenince
Analysis of new oil

4. The two methods to take an oil sample are, to use a small vacuum pump and draw a sample from the dipstick, or take some as its draining from the sump at an oil change.

5. ? Odd wording Jeff

6. I learned that the diffrent types of contamination wil lead to diffrent failers and exesive wear on certen parts depending on what type of contamination you have in your oil.

7. EC 

The signifigence to "The 11th Hour of the 11th Day of the 11th Month"

Is when most major hostilitys ended during WW1 on the 11th hour of the 11th day of the 11th month with the German singing of The Armistice
