Motor-vehicle diesel tank antifreezing system

Abstract

The invention belongs to the technical field of motor vehicle diesel storage, and particularly relates to a motor-vehicle diesel tank antifreezing system. The motor-vehicle diesel tank antifreezing system comprises a diesel storage tank and a controller; the diesel storage tank communicates with a diesel injection pump, and the diesel injection pump communicates with an engine; an exhaust gas outlet of the engine communicates with an exhaust gas inlet of the engine through an exhaust gas outlet tube, a heat exchanging tube and an exhaust gas inlet tube in sequence; and the diesel storage tankis internally provided with an electric heating tube and a temperature sensor, the exhaust gas outlet tube is internally provided with an electromagnetic valve, a signal output end circuit of the temperature sensor is connected to the input end of the controller, and the output end circuit of the controller is connected to the electromagnetic valve. The motor-vehicle diesel tank antifreezing system has the beneficial effects that the electric heating mode is not fully adopted, electric heating is only used for temporary auxiliary preheating, burnthrough of an electric heating tube is not caused, and therefore, the danger of diesel leakage in the electric heating tube is not caused; and opening and closing of the electromagnetic valve are controlled in real time according to the diesel temperature through the temperature sensor and the controller, automatic control over the diesel heating temperature can be achieved, operation is easy, and energy sources are saved.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle oil storage, and in particular relates to an antifreeze system for a motor vehicle diesel tank. Background technique [0002] The current motor vehicle is faced with low temperature in winter, which causes the diesel oil to freeze and freeze wax, so that the chassis cannot be started. In addition, there are some antifreeze measures for diesel tanks that completely use electric heating, but if electric heating is used for a long time, it is easy to cause the electric heating tube to burn through, resulting in oil leakage and causing danger. In addition, the electric heating method cannot automatically control the heating temperature as the temperature changes, resulting in the diesel fuel not being completely thawed, or the heating temperature being too high and wasting energy. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior a...
