Day 37 Sheet

Couldn't Load Day 37 Sheet from my Remote Access at home but heres the answers... Ill load it up monday.

1. Lubrication, Extreme Pressure wear control, cleaning, protection, cooling, sealing, shock dampening, hydraulic actions, and additives.

2. Combustion byproducts, acids, varnish, sludge, abrasive, foreign material, fuel or coolant, environmental.

3. Model/Serial #, Miles/Hours of use, Mules/hour on engine, Oil Brand, date of collection  engine application, amount of oil added since last change, recent maintenance, analysis of new oil.

4. Bring engine to operating temp, purge sample fitting, and clean outside of valve and use a clean dry container.

5. NA

6. Ive always known oil was important but not to near the extent that it really is. Oil plays a role in alot of different things in the engine. My main thought was lubrication, yet it is a big part in so many other things. Telling someone to keep a regular schedule with oil changes can go into how the oil lubricates all parts and keeps things moving smoothly to how oil is used in removing contaminants of engine wear. Oil is also used in the process of keeping the engine cool as it absorbs the heat. One thing that i never really thought too much about is how it also absorbs shock within the engine. Having a high compression diesel engine their is quite a bit of shock produced from igniting fuel and proper engine oil and level are extremely important.

MAINTAIN YOUR OIL! Your truck will love you for it.

7. The 11th hour of the 11th day of the 11th month is a significant date for lots of reasons, yet the most important seems to be the day WWI ended in 1918 and is now the day we celebrate as veterans day. Along with that the draft age was lowered in 1942. A big thanks to all those who have served for me and for America.

Day 34 Sheet

11    The Fuel Control Actuator (FCA ) is an electronically controlled solenoid valve. The ECM controls the amount of fuel that enters the high-pressure pumping chambers by opening and closing the FCA based on a demanded fuel pressure. When the FCA is opened, the maximum amount of fuel is being supplied to the fuel injection pump. Any fuel that does not enter the injection pump is directed to the cascade overflow valve. The cascade overflow valve regulates how much excess fuel is used for lubrication of the pump and how much is returned to the fuel tank through the drain manifold. An audible click from the FCA is normal when operating the key from the ON to the OFF position.

22    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.

33    Electrical supply for the 2 air heater elements is controlled by the Engine Control Module (ECM) through the 2 air heater relays. Refer to Intake Manifold Air Heater Relays for more information.

     Two heavy-duty cables connect the 2 air heater elements to the 2 air heater relays. Each of these cables will supply approximately 95 amps at 12 volts to an individual heating element within the heater block assembly.

4. Codes Present: p0201-P0206- Injection (#) Control Circuit Fires improperly. This is the reason for the No start.

5. This type of Control (horn and wipers) is called Bi-Differential Control.

I found a disconnect in the harness after chasing a bird with the Fuel Control Actuator. THANKS! This bird actually was a good thing to do to keep us thinking about the reason of the codes and no start. It keeps you on track and looking in the right places rather than chasing after something that most likely had little to do with the no start when all cylinder injectors were not firing.

Day 33 Sheet

1. Antifreeze and water, being two different substances that absorb heat at different rates, should be considered in cooling system process. Antifreeze when mixed with water becomes less able to absorb heat. Specifically the loss in capability is about 1 degree Celsius for every 10% of glycol. This ratio will continue up to 50%.

2. Detonation occurs in the cylinder when the “end gas” or unburned fuel air mixture from the primary ignition will self-ignite at an imperfect or wrong time. A number of things play a part in the cause of detonation including fuel quality, compression ration, engine timing, intake air temperature, and aftercooler temperature. The “ping” or “knock” you hear when detonation is occurring is caused by the two leading edges of ignited flame colliding.

3. Along with the regular fluid change intervals a fluid sample, like the SOS of Cat, can be performed to analyze wear and quality of fluid.

4. Combustion air flow requirements will vary, depending on the specific engine model and rating. Specific air flow data for Caterpillar engines is given in both volumetric and mass flow terms, at standard reference conditions.
