An engine control system and control method matching two engines and one propeller

Abstract

The invention discloses an engine control system and a control method matching twin engines and single propellers. The system includes two engines configured with the same type, a gear box, a propeller and a remote control unit; the two engines are respectively connected to the input end of the gear box through a clutch. , the output end of the gearbox is connected to the propeller; the engine is electrically connected to the corresponding engine electronic control unit, and a speed sensor and a fuel feeding unit are installed on the engine; the remote control unit is used to output speed regulation voltage signals and parallel signals to the engine electronic control unit. The control method is implemented based on the above control system. When the remote control unit outputs parallel signals to the two engine electronic control units at the same time, the two engines enter the dual-engine fuel control mode; otherwise, the engine that receives the speed regulation voltage signal enters the single engine speed control mode. The invention can realize automatic load distribution without adding an extra load distributor, has low cost, and can improve the economy of the whole ship.

Description

technical field [0001] The invention belongs to the technical field of engine control in ships, and in particular relates to an engine control system and control method matching twin engines and single propellers. Background technique [0002] Two engines and one propeller means that two engines drive one propeller together. In the prior art, due to the mechanical structure of the gearbox, the load cannot be distributed; if only the speed control strategy is used, that is, the input voltage of the governor handle directly corresponds to the speed, regardless of the load, one engine will bear all the load, and the other The phenomenon of one being towed backwards, the fuel is incompletely burned and discharged directly, which affects the service life of the engine and reduces the emission of greenhouse gases; therefore, ships (sea ships) with two engines and one propeller are often equipped with electronic governors and load sharing The device is similar to the generator set...

Problems solved by technology

In the prior art, due to the mechanical structure of the gearbox, the load cannot be distributed; if only the speed control strategy is used, that is, the input voltage of the governor handle directly corresponds to the speed, regardless of the load, one engine will bear all the load, and the other The phenomenon of one being towed backwards, the fuel is incompletely burned and discharged directly, which affects the service life of the engine and reduces the emission of greenhouse gases; therefore, ships (sea ships) with two engines and one propeller are often equipped with electronic governors and load sharing The device is similar to the generator set in parallel, the engine only needs to control the speed, and the load is distributed and then provided to the engine

However, this technology is usually applied to sea-going ships, and the system is more complicated and the cost is higher; while the tonnage of inland water transport ships is small, the cost is low, and the layout space is small. Transport ships; therefore, in the field of inland rivers, twin engines and double propellers are commonly used, which also limits the application of twin engines and single propellers
