Problems solved by technology

Because the heating position of the fuel is far away from the fuel inlet of the engine, the fuel needs to go through a long pipeline to reach the fuel inlet of the engine. At this time, the temperature of the fuel decreases to a certain extent, resulting in the heating of the fuel entering the engine. Unsatisfactory effect

Abstract

The invention provides a fuel oil heating system which comprises an oil inlet pipe, the oil inlet pipe comprises an outer pipe, an inner pipe arranged in the outer pipe and a connecting rib, one end of the connecting rib is connected with the outer wall of the inner pipe, the other end of the connecting rib is connected with the inner wall of the outer pipe, and a heating channel is formed between the outer pipe and the inner pipe; the left end of the inner pipe is used for being connected with an oil inlet of an engine, and the right end of the inner pipe is used for being connected with an oil outlet of a fuel filter. The two ends of the outer pipe are connected with an engine cooling water pipeline respectively, an inner hole of the engine cooling water pipeline is communicated with the heating channel, and cooling water in the engine cooling water pipeline flows to the other end of the heating channel through one end of the heating channel. Fuel oil flowing in the inner hole of the inner pipe of the oil inlet pipe is heated through cooling water, the heated fuel oil directly flows into an engine, and therefore the fuel oil entering the engine can be well heated.

Description

technical field [0001] The invention belongs to the technical field of engine fuel heating, and in particular relates to a fuel heating system. Background technique [0002] The diesel engine fuel heating system is to increase the temperature of the fuel entering the engine to improve the starting effect of the engine in cold environments. [0003] Currently, fuel heating systems for trucks such as figure 1 As shown, the fuel in the fuel tank is heated by the cooling water pipe 1 integrated on the fuel quantity sensor, and the diesel oil flowing through the diesel filter is heated by the PTC heater 2 on the diesel filter. Because the heating position of the fuel is far away from the fuel inlet of the engine, the fuel needs to go through a long pipeline to reach the fuel inlet of the engine. At this time, the temperature of the fuel decreases to a certain extent, resulting in the heating of the fuel entering the engine. The effect is not ideal. Therefore, how to obtain a b...
