Description
Technical Field
The invention relates to automobile parts, in particular to a split type electronic delay control fuel heating system.
Background
At present, a fuel oil heating system of fuel oil mainly comprises a dual-cavity fuel oil tank and an integrated fuel oil switching valve, and the fuel oil switching valve integrates the functions of switching high and low grade fuel oil, indicating the oil quantity, heating cooling liquid and electronically switching on and off cooling pipe liquid. The fuel switching valve is fixed on the main cavity of the fuel tank and is of a manual switching structure; 0# oil is added into a main cavity of the double-cavity fuel tank, high-grade oil with better frost resistance, such as-20 #, -35#, is added into an auxiliary cavity, and the high-grade oil is more expensive than the 0# oil.
In winter, the high-grade fuel is directly used for starting, the 0# fuel is switched to be used after the 0# fuel in the main cavity is unfrozen during normal running, and the fuel use cost of about 2-3 ten thousand can be saved for a user in each winter.
Because the fuel oil is manually switched, after the coolant reaches a certain temperature or runs for a certain distance or runs for a certain time, a user judges that the fuel oil is unfrozen according to experience, and then gets off the vehicle to operate the switching handle to switch the high-grade diesel oil to the 0# diesel oil, which is not accurate, and the fuel oil is not completely dissolved, so that the switching valve and the fuel oil filter are blocked, and the engine is flameout; also, since the fuel tank is generally disposed on the left side of the entire vehicle, the getting-off operation is not safe, especially on a highway.
