Background technique
Current all motor car engines all need to carry out delivery test before dispatching from the factory, and whether qualifiedly detect Engine Assembling Quality, whether power character, Economy meet design requirement.
Motor delivery test process is: motor is installed on sub-fast-assembling test stand, and warm-up the engine, then carries out total output test, and check whether exist loosen, fracture and leak.Whole process is about 25-30 minute, and wherein the time of warm-up the engine accounts for 8-10 minute.
Summary of the invention
Technical problem to be solved by this invention is: for engine warming up overlong time in motor delivery test in prior art, affect manufacturing efficiency, cause the problem of equipment and energy waste.
The object of the invention is to reduce the engine warming up time, thus increase work efficiency, reduce test energy consumption, reduce testing installation and drop into.
Design philosophy of the present invention is, during test, the cooling liquid heated in engine coolant system is directly injected in motor to be tested, the engine motor oil heated stored is directly injected in motor to be tested simultaneously in engine coolant system in the electric-heating container comprised.
As follows for solving the problems of the technologies described above adopted technological scheme:
A kind of quick heat engine method of motor delivery test, is characterized in that, comprise the steps:
1) prepare engine coolant system, in this engine coolant system, comprise electric-heating container;
2) step 1) in electric-heating container in store temperature at the engine motor oil of 85 DEG C-90 DEG C;
3) step 1) in engine coolant system in coolant temperature scope be 85 DEG C-90 DEG C;
4) adopt coolant duct connecting engine coolant system and motor, the cooling liquid in engine coolant system is directly filled with motor;
5) adopt main oil gallery ready-packaged joint to connect electric-heating container and motor, the engine motor oil in electric-heating container is injected in motor;
6) ato unit, carries out delivery test.
Engine coolant system described in the present invention is engine testing room coolant system, and its concrete structure and working principle the present invention do not elaborate.The present invention is an electric-heating container of connecting in coolant system, heater power is different and different according to test engine model from vessel volume, electric-heating container belongs to routine techniques product, is not therefore also described in further detail for the concrete structure of electric-heating container and working procedure the present invention.
Electric-heating container described in the present invention, engine motor oil constant-temperature quantitative injection device, main oil gallery ready-packaged joint are the routine techniques product of prior art, and therefore, its concrete structure and working procedure the present invention are not described in detail.
Further improvement of the present invention, considers the change being injected into motor inner engine oil temperature that ambient temperature difference causes, step 2) in engine oil temperature be 90 DEG C.To inject in-engine engine oil temperature to be tested be 90 DEG C is a preferred temperature when carrying out delivery test.
Further improvement of the present invention, step 3) in engine coolant system in coolant temperature be 90 DEG C.To inject in-engine coolant temperature to be tested be 90 DEG C is a preferred temperature when carrying out delivery test.
Further improvement of the present invention, step 5) in adopt engine motor oil constant-temperature quantitative injection device to be injected in motor by the engine motor oil in electric-heating container.Engine motor oil constant-temperature quantitative injection device described here is routine techniques product of the prior art, and therefore, its concrete structure and working procedure the present invention are not described in detail.This engine motor oil constant-temperature quantitative injection device is adopted to its objective is that the difference depending on motor energy consumption carries out injection engine machine oil in the present invention.
The present invention has the following advantages compared with motor delivery test in prior art:
1, method of the present invention, because the cooling liquid injected in motor to be tested and engine motor oil reach test temperature substantially, shortened to 2 minutes by the prewarming machine time from 8-10 minute, effectively shortens whole process of the test.
2, adopt method of the present invention, the separate unit motor delivery test test time can foreshorten to about 18 minutes from about 25 minutes, and testing efficiency can improve about 25%.
3, to look motor different and different for energy consumption, considerable for the energy consumption producing saving in enormous quantities.
4, adopt method of the present invention, testing installation quantity can reduce about 25%.
