Abstract

The invention relates to a preheating system for an automobile engine and a controlling method for the preheating system. The preheating system comprises a mobile terminal, a vehicle-mounted controller, an engine control module, a storage battery, an electrical quantity sensor, a cooling liquid sensor, a preheating control module, a heating oil injector and a preheating feedback module, wherein the vehicle-mounted controller can recognize a preheating signal of the mobile terminal; the engine control module detects a feedback signal of the cooling liquid sensor, and transfers the feedback signal to the preheating control module; the preheating control module controls the storage battery to provide power for the heating oil injector; the preheating feedback module transfers the received signal to the mobile terminal. According to the invention, preheating can be conducted when a driver does not enter an automobile; meanwhile, the temperature of the engine can be detected accurately; heating current is controlled according to the temperature; electrical energy is saved; starting waiting time is saved; the start speed of the automobile is improved.

Description

Technical field [0001] The invention belongs to the field of automobile control, and specifically refers to a control method of an automobile engine preheating system. Background technique [0002] At present, there are problems with the startup of automobile engines in cold winter, and low temperature has a great influence on engine startup. The viscosity of the oil increases at low temperatures, which increases the rotation resistance of the engine crankshaft, which will reduce the engine's starting speed. Low temperature will also cause poor fuel vaporization, lower the battery voltage, and make the spark plug less prone to flashover, resulting in increased engine wear and increased engine fuel consumption. [0003] In order to solve the problem of engine starting at low temperature, the engine heating system is generally used. The heater in the traditional engine heating system uses the electric energy of the battery to heat the air in the intake manifold of the engine or hea...
