Problems solved by technology

[0004] (1) The existing engine power grading method is simple, only one operating point of the calibrated power is defined and classified, and the principle of conservative formulation will limit the increase of engine power, and the engine reliability cannot be guaranteed if it is radical
[0005] (2) There is no difference in the maintenance of engines of different power levels, and the guidance to users is not strong

Abstract

The invention relates to the technical field of engines, and discloses an engine power classification method. By calculating strength coefficient, an engine operation region is divided into a plurality of power level regions, different levels operate different power regions, different operation principles are made, annual operation time requirements, average load rate requirements and maximum power operation time requirements are different and displayed by instruments, operation of a user is facilitated, the optimal maintenance scheme is selected according to practical usage of an engine in different power regions, maintenance cost is reduced, and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine power classification method. Background technique [0002] The rated power of the engine is graded according to different usage and operating conditions, and the power enhancement degree of each level is different, and the annual running time, average load rate requirements, and maximum power running time have different requirements. For example, according to the requirements of GBT2820.1, the power of a generator engine is divided into four levels: COP (Continuous Power), PRP (Basic Power), LTP (Display Operating Power), and ESP (Emergency Standby Power). figure 1 . Although there is no national standard requirement for boat engines, the industry is usually divided into four power levels: P1, P2, P3, and P4 according to different usage and operating conditions. [0003] At present, national standards, industry standards, and enterprise standards only define the types...
