Abstract
The present invention discloses a zero side pressure technology and a device for a high heat efficiency internal combustion engine. The technology uses an eccentric shaft of collapsible secondary eccentricity to match the motion of a slide block so as to obtain the zero side pressure of a piston and push an output shaft to rotate. The eccentric shaft is formed by combining a guide rail and a hypocycloid. A traditional crank shaft depending on a primary eccentricity shaft to circumferentially move for obtaining rotation and the tilt angle travel range of a connection rod can be replaced by the technology. Consequently, the technology can eliminate a series of problems that the tilt angle of the connection rod simultaneously generates the side pressure of the piston, side grinding, lag work output application, low heat efficiency, etc. The device of the present invention can replace gasoline internal combustion engine and diesel oil internal combustion engine which are in any variety, shape and type and are provided with a single cylinder or a plurality of cylinders, can make the internal combustion engine of the crank shaft with low heat efficiency become the internal combustion engine with high heat efficiency which can be greatly improved by more than 15%, and meanwhile, can make the internal combustion engine of the crank shaft with low efficiency become the internal combustion engine of high heat efficiency which uses low heat value fuel as energy sources. Besides, the output power of the internal combustion engine of high heat efficiency is not reduced.
Description
Technical field:
The present invention relates to a kind of internal-combustion piston engine, especially a kind of high heat is imitated internal combustion engine zero side pressure technology and device.
Background technique:
At present all vehicles, boats and ships are gone up and all need make the mechanical device of power of internal-combustion engine by society, and its structure of used internal-combustion engine is the bent axle that relies on a throw of eccentric of tradition all, back and forth promotes the technology that bent axle is obtained rotation by piston, the connecting rod of cylinder.Be characterized in: piston back and forth has side pressure, side grinding to cylinder.The main cause that causes the side pressure side grinding is influenced by the pivot angle of crankshaft-and-connecting-rod, so piston side pressure size has become proportional relation with the crankshaft-link rod pivot angle.Original crankshaft eccentric is just big more strong more apart from arm of force of big more (being that piston stroke is big more) its promotion output shaft rotation, and the thermal efficiency is just high more, and oil consumption is low more.But its proportional relation makes piston just big more to cylinder side pressure frictional resistance, has formed the counteracting of power, and the oil consumption, the vibration that produce, wearing and tearing, and noise is all big especially.In addition, when crank angle during in last lower dead center, the arm of force length of its throw of eccentric is zero, and the optimal force arm lengths is positioned at 90 ° of corners, but piston is at top dead center in the time of the strongest, when descent of piston to 90 ° corner during at the best arm of force of bent axle, and the working stroke of piston descending 50%, if 100 kilograms of Driving forces that piston produces, it is 50 kilograms that stroke has weakened when reaching to 90 ° of corners, obviously pistons work power is used and is lagged behind, again because crankshaft-link rod makes the side pressure of piston, the side grinding resistance is maximum when 90 ° of corners, and resistance accounts for 20%, also can only there be 40 kilograms this moment so promote the power of crankshaft rotating, because there is certain frictional resistance in the mechanical structure factor of complete machine, account for 20% again, causing real useful heat to imitate also can only be about 32 kilograms.Imitate (being about 26%～34%) on the low side so crankshaft internal combustion engine is also therefore warm.
People's tackling key problem of all doing one's utmost for this reason, but since everybody all be centered around and rely on bent axle and obtain in the dead scope of rotation technique frame and tackle key problems, so produce little effect.For example strengthen strength and improve machining accuracy, What is more goes up the loss that pottery prevents heat with the casting of piston face, cylinder inner wall, but imitates 2 to 3 percentage points nothing more than improving heat, this just the heat of crankshaft internal combustion engine imitated the peak.That is to say 100 kilograms of fuel of crankshaft internal combustion engine burning, have only 40 kilograms to be acting at most, all the other 60 kilograms all is white burning and waste, atmosphere pollution and environment.
So still relying on bent axle, to obtain the internal-combustion engine of rotation technique all be that low-heat is imitated internal-combustion engine; because it is on the low side that heat is imitated; guarantee the output power of internal-combustion engine again; therefore have only and rely on the power fuel that the high-energy fuel oil is made; can't use low-calorie alcohol, liquid gas, hydrogen and wait and do fuel, the vitality that forms crankshaft internal combustion engine will be in company with because of the oil crisis crisis.The heat that therefore will increase substantially internal-combustion engine is imitated the potential energy that excavates that still has more than 50%, and is very considerable and necessary.
Summary of the invention:
The purpose of this invention is to provide a kind of can substitution society's crankshaft internal combustion engine of any kind of, pattern, model, single cylinder, multiple cylinder diesel or gasoline at present, and can replace all functions of former bent axle, and make original fuel feeding, supply position, working stroke mechanism constant, under the prerequisite that rotational speed does not subtract, make the crankshaft internal combustion engine that low-heat is imitated become a kind of high hot the imitate internal-combustion engine of heat effect more than 15 percentage points that increase substantially, also can become a kind of high heat effect internal-combustion engine that uses lower calorific value as fuel simultaneously; Certainly can allow to redesign out form or variform internal-combustion engine according to service condition and space.
The technical solution used in the present invention is:
1, employing is combined into collapsible secondary throw of eccentric axle by guide rail and hypocycloid, and cooperating the push rod slide block to constitute slide block can produce reciprocal radial motion in the guide rail the inside, obtain the zero side pressure of piston and promote left and right output shaft and the technical characterstic of joining shaft rotation; Realize eliminating piston side pressure, side grinding phenomenon with this technical characterstic, improve heat and imitate.
2, making the best arm of force of elementary throw of eccentric former is 45 ° at 90 ° in advance, guarantees that the pistons work time of exerting oneself uses 45 ° in advance and improve heat and imitate.
3, the raising piston stroke increases aspects such as promoting the output shaft rotary arm and improves the heat effect under the prerequisite that assurance rotating speed power does not subtract.
4, can arbitrarily rationally adjust raising because of piston zero side pressure stroke again, cause the effective characteristic that the cylinder variable capacity increases, therefore just can become the supercharge cylinders oxygen enrichment has in this respect created genetic prerequisite, for the lower calorific value raw material provides enough mass-burning spaces, solving the internal-combustion engine output power needs the calorific value total amount on the other hand.Therefore also become and to slow down few dependence or do not rely on petroleum fuel, can use the internal-combustion engine of the renewable sources of energy.
5, the spindle nose output unit technology of using the no bent axle zero long stroke IC engine patent of side pressure (patent No. ZL012400831) that I have obtained of characteristics is in sum improved, and designs the needs that the crankshaft internal combustion engine that is applicable to present social any kind of, model more transform high heat effect internal-combustion engine as.
Take on the structure:
