About high efficiency PPT evidenced by the fact that they consume power (when installed in the fine filter and coarse filter, and the fuel tank of the car “the Bull”) does not exceed 300 W at a voltage of 12 V. It is acceptable for the operation of the machine when a normally charged battery. Moreover, the time required to warm the fuel using PPT, not to exceed five minutes.
Install domestic PDT may, without special training, any mechanic electrician maintenance automotive equipment. Especially in the fuel purification filter (Fig. 1), which greatly facilitates the design of the heater, a metallic casing which successfully integrated semiconductor heating elements connected to electric system car through the starting relay. Establishing PPD between the filter cover and housing using a gasket with the subsequent contraction of the elongated screw (included in scope of delivery) supplied with a special seal.
As simple turns out to be a typical installation PPT in the fuel tank of the machine or tractor (Fig. 2) where the heater is an aluminum cylinder (mesh), which is from one to six items, depending on tank capacity and fuel consumption.
In such cars as KAMAZ, posistor heaters it is recommended to place a few (Fig. 3). And the algorithm they use then comes down to an easily remembered sequence of simple steps.
Before starting the diesel engine, turn on the heaters fuel tank, and continuous operation.
Overheating is virtually eliminated due to the unique property of the posistor heater — ability to self-regulate. Its semiconductor components are gradually “locked”, thus reducing current consumption to zero. PDT the fine filter is also included for 2-3 min or for permanent use.
The diesel is allowed to idle at high frequency of rotation of the crankshaft. After the engine has come to normal mode, the heaters themselves gradually stopped heating fuel, or you can disable them.
Well, if suddenly a situation arises when the engine power starts to fall because of the paraffin fuel, it should be immediately re-enable the heaters from the cab of the machine to restore normal operation of the diesel engine.
Install on automotive engineering posistor heaters diesel fuel! The costs will pay off.
