Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of ignition order changable type car combustion engine that the utility model proposes, it structurally is a four-stroke reciprocating-piston engine with 9 working cylinders, this motor is different from other motor, and main difference design part is shape of block design, the design of cylinder number, the design of cylinder body cylinder liner central point angle, crankshaft designs and the camshaft design etc. that are it.

Described cylinder number, every row cylinder body in upright arrangement is provided with 3 working cylinders, and three rows cylinder body in upright arrangement is totally 9 working cylinders;
Described cylinder body cylinder liner central point angle is that the angle between the cylinder liner central point of every row cylinder body in upright arrangement is 40 degree;
Described bent axle is three connecting rod journal diameters, the i.e. cylinder rod diameter of axle 12, the three cylinder rod diameters of axle 13, two cylinder connecting rod journal diameter 14, each connecting rod journal diameter drives 3 connecting rod runnings, just drive three cylinder operation, the working cylinder that the one cylinder rod diameter of axle is driven is 1-4-7, the working cylinder that the 2 cylinder rod diameters of axle are driven is 2-5-8, the working cylinder that the 3 cylinder rod diameters of axle are driven is 3-6-9, three connecting rod journal diameters in crankshaft rotating reaches top dead center within one week order are from front to back: 1-3-2, (calculating with the corresponding single cylinder body in upright arrangement of bent axle), the angular interval of top dead center that this order reaches are 120 degree (central point when moving in a circle with bent axle is that the center of circle is measured).
Described camshaft assembly 7, crankshaft rotating are within two weeks, and air inlet of single cylinder body upper cylinder in upright arrangement or exhaust order on camshaft are from front to back: 1-2-3.(calculating) with the camshaft on the single cylinder body in upright arrangement.The angular interval that the cam lift of each cylinder is peaked in this order also is 120 degree (central point when moving in a circle with camshaft is that the center of circle is measured), and the air inlet order on every row cylinder body in upright arrangement, the design of exhaust order on camshaft all are identical.
Dot sequency truly is variable, its crank angle of work cycle of each piston reciprocating type quartastroke engine work all is 720 degree, with this 720 cylinder number of spending divided by this motor is exactly the ignition-powering angular interval of this motor, and it all has a changeless ignition order (referring to multicylinder engine).These all are the routines of general motor, and this motor it two ignition orders can be arranged, and under the situation that all cylinders of motor all do work, carry out mutual variation, this is the technical problem that solves at available engine.First kind is: 1-7-6-2-8-4-3-9-5, its ignition-powering angular interval is 720 degree ÷ 9=80 degree in this ignition order, be on the basis of a work cycle with 720 degree, each cylinder all does work once, just every cylinder piston comes and goes twice between top dead center and lower dead center, once acting in this cylinder (engine power output situation can reach the peak power of motor in this ignition order).Second kind is: 1-6-8-3-5-7-2-4-9, this ignition order is compared what be not difficult to find out that its adopts with first kind be the mode of jumping over the formula ignition-powering on the basis of first kind of ignition order, this makes its ignition-powering angular interval change 160 degree into by 80 degree, just in time double, if it all does work with each cylinder more once is a work cycle of motor, the work cycle of this motor under this ignition order should be 1440 degree (160 degree * 9=1440 degree ignition-powering angular interval * engine cylinder numbers=circuit crank angle of engine operation), will be through two 720 degree, be a work cycle of motor around the crankshaft rotating just, every cylinder piston comes and goes between top dead center and lower dead center in four these cylinders and just once does work.Most crucial cylinder is the 5th cylinder in this ignition order the inside, because begin acting (piston is as the criterion in the process compression stroke top dead center and begins to calculate when all having burning mixture in cylinder) from cylinder acting to 5 cylinders, bent axle just in time rotates 640 degree, doing work afterwards since 5 cylinders, bent axle has just in time passed through first 720 degree at rotation 80 degree one cylinder, yet will rotating 80 degree again, bent axle just can be connected to the acting of 7 cylinders, at this moment 5 cylinders are just just covered to the ignition-powering angular interval between 7 cylinders, and this moment, bent axle rotated 800 degree.160 degree that bent axle rotated after the 5 cylinders actings just 5 cylinders connect the most preceding 80 of last 80 degree that acting angular interval between 7 cylinders just in time is the one 720 degree and second 720 degree and spend sums, 5 cylinders are the cylinders that connect transition between these two 720 degree that bent axle will pass through, so it is most crucial cylinder.When beginning to do work, 7 cylinders entered second 720 degree, also surplus 640 degree of 80 degree have been taken by 5 cylinders to the acting angular interval of 7 cylinders in this 720 degree the inside, it just in time is the summation of 7-2-4-9 cylinder ignition-powering angular interval, Deng again when a cylinder does work bent axle just in time rotate 1440 degree, also just in time finished second kind of ignition order the inside motor 1 work cycle (in this ignition order peak power output situation of motor be under first kind of ignition order situation motor output peak power 1/2nd).
Ignition order is commonly referred to as the order of ignition-powering, the order of acting is lighted in the back of the compression of the burning mixture in each cylinder of this motor just, do not have compressed burning mixture in this cylinder if having only spark plug sparking, the current arcing of spark plug is exactly invalid igniting so, and the acting nature has not existed.So it is exactly the variation of acting order that the ignition order of this motor changes actual, under the constant situation of former spark plug sparking order, as long as changing its fuel injection order just can accomplish, so variation has just taken place in its ignition-powering angular interval, double and reduce one times, power also reduces one times or recover former power thereupon, and these are all because the variation of ignition order causes the variation of ignition-powering angular interval to form.
Have in some large-duty engine designs and can accomplish this point, but the difference of they and the utility model motor is to allow half cylinder of this motor stop jointly doing work reach such purpose, that is to say cylinder that it has half stopping jointly doing work second half the normal acting of cylinder keep the output of power, variation has just taken place in its ignition-powering order like this, and ignition-powering angular interval and power are also all changing (the V12 Cylinder engine just can have such design) thereupon.Its shortcoming is: in a certain period the cylinder that is always all stopping to do work is arranged, cause engine interior mechanical wear inhomogeneous, and the utility model motor demonstrates fully this advantage, and no matter in the middle of any ignition order, all cylinders of motor are all in acting for it.In the middle of first kind of ignition order, the just once acting of each cylinder of every two week of rotation of bent axle, this and other quartastroke engine is as good as.In the middle of second kind of ignition order, 1 work cycle of motor is 1440 degree, and it will be through two 720 degree, and single cylinder 720 is having expansion stroke when spending through first, it has only air inlet, compression and exhaust stroke when spending through second 720, not expansion stroke.It is actual to be exactly two are the process of 1 work cycle with 720 degree and have become one to be the process of 1 work cycle with 1440 degree, does not just have fuel injection to reduce expansion stroke in the work cycle the inside of back one 720 degree and other stroke is constant.Also we can say its 1 work cycle that is single cylinder work 1 work cycle of having had a rest again, and circulation so repeatedly, in the middle of this ignition order process of cylinder acting we can cry its interrupted acting.In the middle of these two kinds of ignition orders, can not cause internal mechanical wearing and tearing inhomogeneous, because motor does not stop the cylinder to do work all the time jointly to motor.Based on the machine work principle that is possessed on its this cylinder number, so that the W Cylinder engine is truly an ignition order is variable.
Wind-cooling heat dissipating, in the middle of second kind of ignition order of W9 Cylinder engine, 1 work cycle of motor is 1440 degree, single cylinder does not have expansion stroke inside entering second 720 degree, because be not burning mixture but do not contain the pure air of fuel oil composition what aspirating stroke entered cylinder interior, be lower than the interior temperature of cylinder owing to enter the temperature of air in the cylinder, so the gas that is discharged from the exhaust stroke the inside of second 720 degree can be taken away the heat of a part of cylinder interior, it equals each cylinder of motor and has carried out the first cooling by wind heat radiation for again own cylinder interior in the work cycle the inside of 720 degree that stop to do work, the probability of detonation and high temperature is reduced greatly, and the V12 motor it though the design of the power output of reducing by half is arranged, but no matter it still does work at full cylinder number in the acting of half cylinder number, it all is to be 1 work cycle and so repeatedly acting all the time with 720 degree, it can be as the utility model under the situation that the ignition-powering angular interval equates, the V12 motor allow motor each cylinder when rotation 1440 is spent only do work once, so can't be accomplished this point.
