The parts heating diesel fuel
In
the diesel fuel are not soluble wax in the fuel, which will freeze when
the air is close to zero degrees it will clog the fuel filter. To overcome these added heating fuel. The main part of the fuel heater consists of a heating element and vacuum switches.
1. Vacuum Switch
Vacuum
switches mounted on the top of the fuel filtrt to avoid differences in
fuel pressure inlet and outlet section on the fuel filter. When the pressure difference is greater than the provision, the magnet will move toward the outlet and connect the reed switch. This results in an electric current flows through the heating element fuel.
2. Fuel heating element
The heating element is paired in the fuel filter housing, which housing memenaskan hereinafter fuel flow through the housing. This element is made from ceramic materials that inmates can rise sharply when the temperature rises. Therefore,
the element itself can be used as a temperature control that can stop
the flow of electricity when the temperature has reached a certain
limit. The way this works is more secure than with conventional heating elements.
How it Works
At low temperatures, the wax contained in the fuel will solidify and clog the filter portion. This will cause the difference in inlet and outlet. When
this difference reaches 150mHg, vacuum switches going on and the
electric current flowing through the heating element fuel. It will melt the wax so as not to clog the filter. When
the pressure difference drops below 120mHg, the vacuum switch off to
stop the flow of electricity to the heating element fuel.
