Control system and method for preventing automobile diesel oil from condensing

Abstract

The invention provides a control system and method for preventing automobile diesel oil from condensing. The system comprises a master controller (1), a low-temperature sensor (2), a low-temperature signal preprocessing module (3), a high-temperature sensor (4), a high-temperature signal preprocessing module (5), a viscosity sensor (6), a viscosity signal preprocessing module (7), a first relay (8), a heating coil (9), a second relay (10), an electromagnetic switch (11), an acousto-optic alarm module (12) and a data storage module (13). According to the method for preventing the automobile diesel oil from condensing, the low-temperature sensor (2), the high-temperature sensor (4) and the viscosity sensor (6) are correspondingly used for collecting temperature signals and viscosity signals,moreover, the electrification of the heating coil (9) is effectively controlled through the control of the master controller (1), and meanwhile, the actuation of the electromagnetic switch (11) is accurately controlled, so that the effective supply of fuel oil at an outlet of an oil pump to the heating area of an exhaust pipe is controlled. Compared with the prior art, effective utilization of tail gas waste heat is realized, and the kinematic viscosity of diesel oil is reduced.

Description

technical field [0001] The invention belongs to the field of intelligent automobile control, and in particular relates to a control system and method for preventing condensation of automobile diesel oil. Background technique [0002] In the severe winter, especially in the northern regions, when the temperature drops sharply, due to the inability to replace the diesel with a higher grade in time, some vehicles will suddenly break down after turning off the engine midway, making it impossible to drive normally. This is not only the case for long-distance operating vehicles, but it is not uncommon for some northern cities to report that some buses were paralyzed overnight due to sudden changes in the weather, which brought great inconvenience to people's life and work. These phenomena affecting the normal driving of the vehicle are mainly due to the fact that low temperature has a great influence on the viscosity of diesel oil. When the external temperature where the vehicle i...

Problems solved by technology

Since the control signal of the relay is completely controlled by manual experience, parameters such as the engine exhaust waste heat temperature, the temperature of the fuel tank environment, and the operating time of the heating element during the system operation cannot be accurately grasped, and the engine exhaust waste heat cannot be fully utilized. big security risk
