Problems solved by technology

However, when the diesel engine has been shut down for a long time or the diesel engine is in a cold state, due to the low temperature of the lubricating oil, it takes a long time for the pre-supply pump to build up pressure, which will easily lead to the overload of the pre-supply pump, that is, the pump is easily As a result, the temperature of the motor is too high, the coil resistance becomes larger, and the driving ability is weakened, which makes the starting time of the diesel engine too long, thereby reducing the starting efficiency of the diesel engine

Abstract

The invention discloses a diesel engine starting control method and device, a storage medium and a vehicle-mounted terminal.The method comprises the steps that when lubricating oil is pre-supplied to a diesel engine, first lubricating oil pressure at different moments is recorded in real time; when the pre-supply duration of the lubricating oil reaches the preset duration and the first lubricating oil pressure at different moments does not reach the preset lubricating oil pressure within the preset duration, recording the second lubricating oil pressure when the pre-supply duration of the lubricating oil reaches the preset duration; calculating an oil pressure rise rate according to the second lubricating oil pressure; whether to start the diesel engine is determined based on the oil pressure rise rate. Due to the fact that judgment is carried out through the oil pressure rising speed, the pre-lubrication meeting condition is widened, meanwhile, the lubricating oil pre-supply duration is shortened, the risk of pump overload is reduced, and the starting efficiency of the diesel engine is improved.

Description

technical field [0001] The present invention relates to the technical field of diesel engines, in particular to a diesel engine starting control method, device, storage medium and vehicle-mounted terminal. Background technique [0002] In order to ensure the safe and normal operation of the diesel engine, the diesel engine is generally equipped with a pre-supply pump, that is, an electric oil pump. The pre-supply pump operates before starting the diesel engine to pre-supply lubricating oil. After starting the diesel engine, the pump stops working, so that a lubricating oil film is formed between the moving parts. One is to prevent the dry grinding of the diesel engine after starting, which will cause the wear of parts; the other is to take away the heat and prevent the temperature of each moving part from being too high. [0003] In the prior art, for a large-bore diesel engine with lubricating oil pressure interlocking when starting, pre-supplying of lubricating oil is req...
