Abstract

The invention discloses an engine cold start auxiliary device and a control method, comprising an engine and a water supply tank, characterized in that the water supply tank includes a main cabin and an auxiliary cabin, an electric heater is arranged in the main cabin, and an electric heater is provided in the main cabin. The water outlet and the water outlet of the main cabin, the water inlet of the main cabin is connected with the water supply pipeline of the main cabin, the first engine water inlet pipeline is arranged between the water outlet of the main cabin and the water inlet of the engine, the auxiliary cabin is provided with the water inlet of the auxiliary cabin, and the auxiliary cabin An engine water outlet pipeline is provided between the water inlet and the water outlet of the engine, and the engine water outlet pipeline is provided with a coolant pump and an engine water outlet electromagnetic valve, and the engine water outlet electromagnetic valve and the electric heater are electrically connected to the controller. When the engine starts cold, the electric heater heats the coolant in the main compartment, the low-temperature coolant of the engine enters the auxiliary compartment, and the high-temperature coolant in the main compartment enters the engine, which rapidly increases the temperature of the engine body and improves the cold start performance of the engine.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine cold start auxiliary device and a control method. Background technique [0002] Marine engines are prone to start-up difficulties in cold conditions, which brings great troubles to customers. At the same time, the water vapor in the existing water tank will take away the coolant, and customers need to keep adding it, especially for ocean-going or coastal ships, where fresh water is scarce. ,cause inconvenience. [0003] With the improvement of the ship's requirements for intelligence, the existing water replenishment tanks cannot meet the requirements of intelligent control or unmanned cabins. Contents of the invention [0004] In view of the above problems, an object of the present invention is to provide an engine cold start auxiliary device. As the same inventive concept, another object of the present invention is to provide a control method for an engine cold sta...
