Description
Technical field
The present invention relates to a kind of field of internal combustion engine, especially a kind of can the energy-saving efficient engine of emptying waste gas.
Background technique
We know that the gas after engine combustion acting can not be combustion-supporting again, but these waste gas but occupy the space of fresh air, the content of oxygen is reduced, thus burning after waste gas be discharged cleaner, then motor institute work is larger, and efficiency is also higher.But the volume due to engine chamber is fixing, therefore generator in exhaust stroke at the end, waste gas all can not be drained, always be detained next part residual gas, the oxygen in fresh air is diluted due to residual gas, so have impact on the output power of motor, and output harmful gas carbon monoxide and nitrogen oxide etc.Residual gas is more, then oxygen content is just relatively fewer, and fuel combustion is more insufficient, make acting less, and the harmful gas carbon monoxide of output and nitrogen oxide etc. is more.This is because fuel burns under the condition of oxygen enrichment will generate carbon dioxide, just easily generate carbon monoxide when the condition of anoxic.Again because oxygen content has lacked, then the content ratio of nitrogen will be many, and when burning, excessive nitrogen will absorb heat and oxygen participates in reacting, and generate harmful nitrogen oxide, cause the energy of motor to reduce further.
In order to improve engine efficiency and reduce harmful gas to the pollution of environment, people take a lot of way, also obvious effect is achieved, wherein improving compression ratio is exactly example, facts have proved that compression ratio is higher, the thermal efficiency is higher, this one of them very important reason be exactly in compression ratio and cylinder remaining waste gas be inversely proportional to, the remaining waste gas in the larger then firing chamber of compression ratio is fewer, makes power efficiency also larger.So petrolic boil down to 6 ~ 10 before several years, the now is generally all between 9 ~ 12.
But it is limited for improving compression ratio, when compression ratio is excessive, not only can not improve combustion case further, there will be the phenomenons such as the malcombustions such as detonation on the contrary and reduce the power of motor.This is that the combustion characteristic of gasoline determines, when the temperature and pressure in cylinder is elevated to a certain degree, the mixed gas in cylinder will automatic combustion and exploding, and pressure and the temperature of this automatic combustion are called critical value.If the pressure in cylinder has exceeded critical value, gasoline will have been lighted before ignition because of compression, and this phenomenon is called as pinking, motor can be made to reverse, also cause larger injury to motor.And for turbosupercharged engine, after turbosupercharging gets involved, the pressure of firing chamber can raise further, pinking just more easily occurs, so improve compression ratio can discharge more waste gas, is the energy-conservation measure of fuel-economizing, but energy-conservation limited extent.
Summary of the invention
The object of the present invention is to provide a kind of can the energy-saving efficient engine of emptying waste gas,. to solve the problem of combustion chamber of air cylinder's retentate portion residual gas, thus improve output power and the efficiency of motor, reach the object reducing harmful gas carbon monoxide and nitrogen oxide simultaneously, even if motor also can reach higher efficiency when low compression ratio, to reduce the trouble that high compression ratio is brought.
Technological scheme of the present invention is: a kind of can the energy-saving efficient engine of emptying waste gas, include the parts of common engine, as cylinder, bent axle, piston, intake valve and exhaust valve etc., it is characterized in that: a newly-increased exhaust events plug at the top of cylinder, is connected with cylinder with spring; This exhaust events plug can slide up and down, and driven by exhaust valve and run, slide to piston direction when being vented, remaining space in compression cylinder, reaches the object of emptying waste gas to greatest extent.Upwards automatic returning original position is driven by exhaust valve again, so that many inhale fresh airs when suction stroke.
The invention has the advantages that by emptying waste gas, make the content of oxygen increase and make fuel combustion more abundant, thus increased substantially the power efficiency of motor, reach fuel-efficient object.Because the ratio of oxygen increases, so equally can fuel-economizing on the motor of low compression ratio.The waste gas that simultaneously temperature is very high due to emptying, can reduce Yin Wendu too high and cause the probability of detonation in advance, so be also applicable to the motor of high compression ratio, especially be applicable to turbosupercharged engine.The increase of oxygen content is also the major measure that harmful gas reduces, and is more conducive to environmental protection.
In order to reach this purpose, need to do certain change to original motor, owing to adding exhaust events plug, so the upper end of original exhaust valve needs increase exhaust auxiliary rod, simultaneously object drives exhaust events plug to run, simultaneously.Again because exhaust events plug occupies the position of intake valve, so need intake valve to move to the position of cylinder side near top from the top of original cylinder, the work of exhaust events plug would not be affected like this.
The maximum volume of cylinder is constant, piston-shaped to remain unchanged with position.When exhaust stroke, exhaust valve moves down, and exhaust steam passage is opened wide, be vented auxiliary rod drives exhaust events plug to run, to reduce the space of firing chamber, at the end of exhaust stroke downwards simultaneously simultaneously, in cylinder, remaining waste gas space is minimum, and waste gas is all discharged.Upon inhalation, exhaust valve moves up, and drive exhaust events plug together upwards to run, at the end of exhaust stroke, in cylinder, remaining waste gas space is maximum, so that the more fresh air of inspiration.
