Problems solved by technology

[0003] However, due to the lack of target setting for combustion system parameters, the development of the combustion system, which has a great impact on engine performance, cannot be directly related to the formulation of performance parameters, that is, it is impossible to target the entire engine during the thermodynamic development stage and the engine verification development stage. Effective feedback on the performance parameters of the machine, resulting in repetitive and inefficient processes between the design of the machine and the simulation of the engineering prototype, which seriously wastes time and financial resources

Abstract

The invention discloses an engine design method. The method comprises the steps of setting out target performance parameters of an engine; dividing the target performance parameters of the engine into target combustion parameters of the engine under multiple working conditions; formulating a corresponding design scheme for a combustion model engine according to each specific working condition, so that actual combustion parameters of each working condition under the corresponding design scheme can be collected; when the actual combustion parameters meet preset evaluation criteria, adopting the design scheme corresponding to the actual combustion parameters for designing the engine. By means of the engine design method, the engine design and development efficiency can be raised, the low-efficiency procedure reciprocating is avoided, and the development time and development expenses are saved accordingly.

Description

technical field [0001] The invention relates to the field of engines, in particular to an engine design method. Background technique [0002] In the existing engine development and design, the design of the whole machine is usually started after the performance parameters of the whole machine are formulated, and then the engine trial production, experiment and correction and optimization for the problems in the engineering prototype are carried out in sequence. [0003] However, due to the lack of target setting for combustion system parameters, the development of the combustion system, which has a great impact on engine performance, cannot be directly related to the formulation of performance parameters, that is, it is impossible to target the entire system in the thermodynamic development stage and the engine verification development stage. The effective feedback of the performance parameters of the machine results in repetitive and inefficient processes between the design...
