Intelligent temperature-controlling and fuel-supplying system of diesel car

Abstract

The invention discloses a diesel engine intelligent temperature-control fuel-feed system, resolving the technical problem that the diesel engine is difficult to start and easy to misfire under low-temperature environment. It is mainly composed of fuel tank, erect oil pipe, sedimentation glass, oil pipeline and automatic control circuit. The erect oil pipe is formed of two copper pipes interlinked, the interlayer of the erect oil pipe is vacuum and filled with head conducting medium and the bottom of the erect oil pipe is linked with the first no-red heat source body; the bottom of filter screen of the sedimentation glass is linked with the second no-red heat source body; the environmental temperature sensor is near the sedimentation glass and linked with the temperature control signal; the temperature controller is linked with the two heat source bodies as well as the vehicle power supply. It is widely applied to the manufacture of various diesel oil vehicles.

Description

Technical field [0001] The invention relates to the manufacturing industry of diesel vehicles, in particular to an intelligent temperature-controlled fuel supply system for diesel vehicles. Background technique [0002] The fuel supply system of diesel vehicles generally still adopts traditional technology, and there is no special device for heating fuel. When the outside temperature is low, the viscosity of diesel oil increases, resulting in poor fuel supply, which not only makes it difficult to start the engine, but also It is easy to turn off the flame. For this reason, the methods of roasting with fire or heating with hot water are often used, which is very inconvenient to operate. At present, there is a kind of oil circuit heater on the market. Its principle is to wind the electric heating wire on the device of the fuel supply system. There are four defects in using this kind of heater, one is unsafe, the other is short life, and the third is only It can solve the prob...

Problems solved by technology

[0002] The fuel supply system of diesel vehicles generally still adopts traditional technology, and there is no special device for heating fuel. When the outside temperature is low, the viscosity of diesel oil increases, resulting in poor fuel supply, which not only makes it difficult to start the engine, but also It is easy to turn off the flame. For this reason, it is very inconvenient to use the method of roasting or heating with hot water.

At present, there is a kind of oil circuit heater on the market. Its principle is to wind the electric heating wire on the device of the fuel supply system. There are four defects in using this kind of heater, one is unsafe, the other is short life, and the third is only It can solve the problem of cold start, but it cannot prevent the flameout in the middle. Fourth, the power consumption is high and the thermal efficiency is low.
