Description
Technical field
The utility model is related to automobile technical field, the vapour of especially a kind of five Stroke Engines with high expansion ratio
Car.
Background technology
With the development of society, increasing people has automobile, and reduction oil consumption now turns into of concern one
Individual focus, the factor of influence oil consumption mainly has：1) vehicle weight；2) thermal efficiency of engine；3) road conditions are travelled, automobile has certainly
Oneself " economic speed per hour ", is typically designed in 70~90 kilometers of regions.If, can be unblockedly in city in this speed
Travelled in city, but unfortunately, in the few so straightway big cities of China, when " when automobile runs a good foot not as bicycle ",
Because engine power is excessive, the increase of oil consumption is very big, therefore, when big city is travelled, it is necessary to reduce the row of engine
Amount, and then reduce the power of engine.
The principal element of influence engine thermal efficiency has ignition temperature, delivery temperature, compression ratio, pressure at expulsion, according to heat
Mechanics law, theoretical thermal efficiency=1- (T low temperature/T high temperature), therefore under equal capacity, improve engine combustion temperatures, combustion
Material and air Mixture density, reduction delivery temperature and pressure at expulsion are most efficient methods, but while improving compression ratio, are held
It is easily caused combustion knock.I.e. under certain conditions (such as compression ratio is too high), the burning of gasoline engine can become abnormal, and pressure is bent
There is high frequency in line, fluctuates widely, the dp/dt values rapid fluctuation of near top dead center up to (dp/dt) max=0.2Mpa/us it
Height, the now change of flame propagation velocity and the generation of flame front shape drastically, this phenomenon is referred to as detonation, and pinking is detonation
External reaction.And traditional idea thinks the expansion ratio that is equal to of the compression ratio of engine, compression ratio is limited with pinking, is unfavorable for swollen
The ratio between volume of cylinder when volume of cylinder starts with workmanship stroke at the end of the raising of swollen ratio, expansion ratio, i.e. internal combustion engine workmanship stroke.
Miller cycle is that in the range of detonation temperature, the characteristics of circulation can improve expansion ratio, Miller cycle is engine
Effective compression ratio be less than expansion ratio, Miller cycle is actually to change the IC Intake Valve Closes moment so that engine produce
Backflow, engine compression ratio and expansion ratio separation, increase expansion work, and pinking will not occur for engine.
