The Process of Engine Cleaning System
2014-12-04Microscopic engine cleaning system purging process is as follows:
1) In the intake process of the engine, the mixed gas is sucked into the engine.
a. Hydrogen gas is very light, quickly spread to the engine the engine room.
b. Hydrogen also has a nice feature is the ability to adhere to, is always attached to the wall of the engine room, where they are the most carbon place.
c. Hydrogen also has a feature that penetration, due to molecular hydrogen is small, can quickly penetrate into the surface layer of coke.
2) The cleaning engine fuel injection
3) The engine ignition
a. first phase: the oil, the air, the hydrogen attached to the carbon surface, oxygen is ignited, produce carbon oxides (mainly carbon dioxide), nitrogen oxides, and the high temperature steam and other groups of hydroxide ions.
b. The second phase: water vapor, carbon hydroxide ions corporations and high-temperature water gas shift reaction occurs, attached hydroxyl ions are oxidized to carbon monoxide and further oxidized to carbon dioxide.
4) The engine compression work
5). Exhaust: Coke in a gas way through the exhaust system
Above 5 steps for a micro carbon removal process, each purge soot thickness of about 0.2 microns (i.e. nanoscale), idling 720 turn as an example, the completion of such a cleaning process 720 times per minute, 20 minutes 14400 times to complete the cleaning process, a total of about 2.88 mm can remove carbon deposits = 14400 * 0.2 microns.
After 20 minutes of carbon removal process, you may not be completely removed all the carbon, but the engine room of carbon after several water-gas reaction by a dense solid into a honeycomb structure of the state, by not burning (glue quality) can become combustible burn slowly (because the process has already started in addition to carbon in soot constantly hydrogen). After stops engine cleaning machine can still be burned slowly.
