Engine cold start auxiliary device and control method

Abstract

The invention discloses an engine cold start auxiliary device and a control method. The engine cold start auxiliary device comprises an engine and a water replenishing box, and is characterized in that the water replenishing box comprises a main cabin and an auxiliary cabin; an electric heater is arranged in the main cabin; a main cabin water inlet and a main cabin water outlet are formed in the main cabin; a main cabin water replenishing pipeline is connected to the main cabin water inlet; a first engine water inlet pipeline is connected between the main cabin water outlet and a water inlet of the engine; an auxiliary cabin water inlet is formed in the auxiliary cabin; an engine water outlet pipeline is arranged between the auxiliary cabin water inlet and a water outlet of the engine; theengine 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 with a controller. When the engine is cold-started, the electric heater heats cooling liquid in the main cabin, low-temperature cooling liquid of the engine enters the auxiliary cabin, high-temperature cooling liquid in the main cabin enters the engine, the temperature of an engine body is rapidly increased, and the cold starting performance of the engine is improved.

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...
