this happened to my 01 7.3 we had to have the brain replaced it did it three times over the course of a year you may wont to check with a Ford dealer to see if this is the answer to your problem
18.6 ATM for diesel UDER ATMOSPHERIC PRESSURE AND TEMPERATURE.
Diesel burns when in an open container, it is not as volatile as gasoline. If you flick a match into diesel fuel, it will typically go out unless it is hot enough to vaporize due to the temperature. In a diesel engine, the fuel explodes when it gets to the right temperature, caused by pressure.
Diesel is burned at higher pressure, higher temperature, and at oxygen excess. Means it burns cleaner and more efficiently.
what temperature does diesel freeze at in Celsius
Actually, diesel is quite a tricky thing to get lit. Diesel's flash point (depending on what text book you read) varies from 100 degrees - 140 degrees F. Flash point means at which temperature the liquid releases a flammable vapor. Therefore, by simply throwing a match on it, unless the diesel is already pre-heated to the temperature, the match will simply go out. By applying pressure to the diesel, (enormous amounts) you can create a pressure explosion --- what happens in a diesel engine.
The ignition temperature, (temperature at which diesel fuel ignites) is 490*F. This temperature corresponds to a set compression of the gasses in the cylinder of the engine. Some, but not all, diesel engines have glow plugs to initially warm the air when you first start the engine because the temperature of the air in the diesel engine is too cold to get the ignition temperature simply from compression. while the engine is running the compression heats the air to the ignition temperature. This compression (or pressure) is the same each time the cylinder fires. Using the universal gas law you can find that corresponding compression versus the ambient temperature and pressure. Typically this will occur at approximately 16 bars. Almost all diesel engines are designed to operate at a compression ratio of 15:1 - 20:1, less if supercharged or turbocharged.
The high pressure oil lines on top of the motor under the fuel and water separator are rubbing together and causing holes
it is ignited due to the high temperature caused by the pressure inside cylinder, when it is compressed.
The main reason of not using the spark plugs in diesel engines is because of the diesel having a low ignition temperature. At the end of the compression stroke the pressure and temperature values achieved are sufficient to ignite the diesel which is sprayed into the hot air in the combustion chamber.
The diesel combustion pressure depends on various factors. The model and the type of diesel engine is important.
diesel has a lower boiling point than antifreeze. as the engine heats up the diesel will vapourize and cause high pressure in your system. you will also has much worse temperature control in your engine.
A boiler is used to boil water, but many boilers work at high pressure so the temperature could be up to about 300 degrees C. Boilers are usually fed with oil that is heavier than diesel, while diesel is used to fuel diesel engines.
