Embodiment 1

[0027] Example 1

[0028] The existing ship A adopts X-type marine engine, which is equipped with relevant hardware such as engine control system, operation panel, fuel temperature sensor, etc., and its mutual connection relationship will not be described in detail, and the engine control system The light / heavy fuel mode automatic conversion control program is implanted in the engine;

[0029] When the ship is driving in the offshore waters, the above-mentioned light / heavy fuel mode automatic conversion control program is not started, the engine control system of the X-type marine engine directly uses the light fuel mode, and the engine runs normally for 20 nautical miles.

[0030] After the ship sails into the deep sea area, the above-mentioned light / heavy fuel mode automatic conversion control program is started, the engine control system extracts the temperature value collected from the fuel temperature sensor, and no fuel inlet temperature is detected, that is, the fuel in...

Embodiment 2

[0032] Existing ship B adopts X-type marine engine, which is equipped with related hardware such as engine control system, operation panel, fuel temperature sensor, etc., and its mutual connection relationship will not be described in detail, and the engine control system The light / heavy fuel mode automatic conversion control program is implanted in the engine;

[0033] When the ship is driving in the offshore waters, the above-mentioned light / heavy fuel mode automatic conversion control program is not started, the engine control system of the X-type marine engine directly uses the light fuel mode, and the engine runs normally for 30 nautical miles.

[0034]After the ship sails into the deep sea area, start the above-mentioned light / heavy fuel mode automatic conversion control program, the engine control system extracts the temperature value collected from the fuel temperature sensor, the value of the fuel oil inlet temperature is 85°C, if it is greater than the specified value...

Embodiment 3

[0036] The existing ship C adopts X-type marine engine, which is equipped with related hardware such as engine control system, operation panel, fuel temperature sensor, etc., and its mutual connection relationship will not be described in detail, and the engine control system The light / heavy fuel mode automatic conversion control program is implanted in the engine;

[0037] When the ship is running in the sea, start the above-mentioned light / heavy fuel mode automatic conversion control program, the engine control system extracts the temperature value collected from the fuel temperature sensor, the value of the fuel oil inlet temperature is 41 ℃, if it is less than a specific value of 80 ℃, start the timer , through multiple judgments by the engine control system within 5s that the fuel inlet temperature values ​​are all less than 80°C, the light / heavy fuel mode automatic switching control program sends a signal to the engine control system to ensure that the engine control syst...

Abstract

The invention discloses an automatic light oil mode and heavy oil mode switching control method. The automatic light oil mode and heavy oil mode switching control method comprises an engine control system and an operation screen connected with the engine control system; a light oil mode and a heavy oil mode are set in the engine control system, a timer is arranged in the engine control system, a fuel oil temperature sensor connected with the engine control system is installed on an oil delivery pipe entering an engine combustor, an automatic light oil mode and heavy oil mode switching controlprogram is implanted into the engine control system, and whether the automatic light oil mode and heavy oil mode switching control program is started or not is selected by operating the operation screen; and the engine control system extracts numerical values of fuel oil inlet temperature, and whether the engine control system adopts the light oil mode or the heavy oil mode is determined accordingto the numerical value condition of the fuel oil inlet temperature after judgment within interval time. According to the automatic light oil mode and heavy oil mode switching control method, the costof engine peripheral accessories is reduced, and meanwhile the safe operation performance and the intelligent operation performance of an engine are improved.

Description

technical field [0001] The invention relates to a light / heavy oil mode automatic conversion control method. Background technique [0002] Marine engines can use ordinary diesel oil with relatively low fuel density and heavy diesel oil with relatively high fuel density. In order to save costs, marine engines use heavy diesel oil when driving in deep sea areas. The engine uses ordinary diesel. Therefore, the above-mentioned marine engine will be equipped with a light / heavy oil conversion device to provide ordinary diesel or heavy diesel to the combustion chamber of the engine. When the engine uses ordinary diesel, the engine control system is set to light oil mode (MDO mode). When the engine When heavy diesel oil is used, the engine control system is set to heavy fuel oil mode (HFO mode). In the above two modes, the alarm settings of parameters such as fuel pressure and fuel temperature in the engine control system are completely different. [0003] In the prior art, a light...
