The invention discloses a method and a device for monitoring the oil consumption situation of a diesel engine. The method comprises the steps of 1, under the same working condition and different altitude conditions, calculating an oil ring technology parameter and the oil consumption of the diesel engine to obtain a relational expression between the oil ring technology parameter and the oil consumption; 2, measuring the actually measured oil consumption of the vehicle-mounted diesel engine; 3, utilizing the actually measured oil consumption and the relational expression to obtain an oil ring technology parameter; 4, comparing the obtained oil ring technology parameter with an oil ring technology parameter threshold so as to judge whether the oil consumption of the diesel engine exceeds the standard or not. According to the method for monitoring the oil consumption situation of the diesel engine disclosed by the embodiment of the invention, the influence of the operation working condition and the environment are fully considered, so that the oil consumption situation can be accurately monitored, the overhaul time can be accurately determined, an accurate means is provided for judgment for the technical situation of the diesel engine, maintenance resources are saved, and the serviceability rate of a vehicle is improved.
Description
technical field [0001] The invention relates to monitoring the technical condition of a diesel engine, and in particular to a method for monitoring the engine oil consumption of a diesel engine and a device for monitoring the oil consumption of a diesel engine. Background technique [0002] During the use of the diesel engine, with the increase of working time, the cylinder liner-piston group wears out, and the elasticity of the oil ring decreases, which increases the oil consumption in the cylinder and increases the oil consumption of the diesel engine. The oil consumption is the technical status of the diesel engine. One of the important indicators of evaluation. At present, the evaluation methods for the increase of diesel engine oil consumption mainly adopt the empirical formula method and human subjective evaluation and judgment. Evaluate the oil consumption status. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned tec...
