So far, the fourth stage in break-in method is completed, and in above-mentioned fourth stage, often completes 2000rpm, a 2bar
Engine operating condition, contrast and once record engine oil pressure, oil temperature and fuel consumption, contrast air inlet pressure can also be contrasted
The parameters such as drop, exhaust back pressure, oil consumption, throttle opening, when at least one data have exception, carry out engine an inspection,
After engine condition to be confirmed is normal, previous action is repeated, contrast 2000rpm, throttle wide after completes fourth stage
Engine towing astern loses, and when the data of engine towing astern loss occur abnormal, for example towing astern moment of torsion is fallen than what is tested before
Drag moment of torsion bigger than normal, then return to first stage break-in again, if not occurring exception, break-in terminates.
It should be noted that in the present embodiment, in 3/4 maximum safe load, the operating mode of maximum safe load, to starting
Machine carries out enriching oil spout, opens exhaust valve opening degree, at this time, needs important to note that delivery temperature (delivery temperature is less than 950 DEG C) and quick-fried
Earthquake situations condition, the angle of ignition are added and subtracted with 0.375CRK, and (exhaust valve opening degree can step-length before 40% with 0.1 degree of plus-minus for exhaust valve opening degree
It is slightly larger, but small step-length is had to afterwards, supercharging effect rises substantially at this time, and delivery temperature easily exceedes 950 DEG C of limit value).It is in addition, every
During the operating mode change of secondary engine, first change load to safety zone, then change rotating speed, that is, it is in underload to ensure rotation speed change
Lower progress.
Petrol engine break-in method according to embodiments of the present invention, clicks through in engine break-in program in multiple operating modes
Row monitors break-in state in real time, realizes the passability inspection of detail in the period of adjustment, while can between each operating point
Check whether engine is normal, can pinpoint the problems in time using identical operating point (2000rpm, 2bar), and when engine falls
When dragging the data of loss to occur abnormal, first stage break-in again can be all returned, avoids engine damage, and monitoring is started in real time
Whether machine break-in state, friction level have reached stable, and whether engine oil pressure has reached stable, the engine that break-in is completed is existed
All stable operation during follow-up test, fully improves the break-in of engine key position, and depth has excavated engine
Engine Durability energy and can be strengthened, improve running-in effect.
