The big 1E50F cylinder of petrol engine of rate.
The 1E50F cylinder of petrol engine of above-mentioned technical problem is can solve the problem that, its technical scheme includes being opened on cylinder body casing wall
Air inlet, exhaust outlet and scavenging air belt, except that it is 66mm that the cylinder diameter of the cylinder body, which is 50mm, cylinder depth,；The scavenging air belt
Including the first scavenging air belt and the second scavenging air belt side by side, the height of the first scavenging air belt is away from cylinder base 37.6mm, the second scavenging air belt
Height away from cylinder base 37.1mm；The upper top of the air inlet bore is away from cylinder base 28.1mm, lower bottom away from cylinder body bottom
Portion 16.1mm, the upper top of the exhaust outlet bore is away from cylinder base 42.1mm, lower bottom away from cylinder base 30.6mm.
The parameter for configuring the 1E50F gasoline engines of the cylinder body is：Combustion chamber volume is set to 6.8 ± 0.5cc, and discharge capacity is set to
66.7CC, peak power is set to >=2.2Kw/7000rpm.
The beneficial effects of the utility model：
1st, the utility model 1E50F cylinder of petrol engine makes burning more fill by expanding cylinder diameter, the measure of optimization port timing
Point, reach purpose that is fuel-efficient, reducing carbon distribution, improve power durability.
2nd, the utility model can effectively meet the larger requirement of such type power demand amount, wide market.

Figure number is identified：1st, cylinder body；2nd, air inlet；3rd, exhaust outlet；4th, the first scavenging air belt；5th, the second scavenging air belt；6th, cylinder cap；7、
Spark plug.
Embodiment
Illustrated embodiment is described further to the technical solution of the utility model below in conjunction with the accompanying drawings.
The utility model 1E50F cylinder of petrol engine, including be opened on the casing wall of cylinder body 1 air inlet 2, exhaust outlet 3 and sweep
Air flue, the air inlet 2 and exhaust outlet 3 be relative and equal insertion casing walls, the scavenging air belt (non-penetrating casing wall) located at air inlet 2 with
In the middle of exhaust outlet 3, scavenging air belt is vertical side by side two, respectively the first scavenging air belt 4 and the second scavenging air belt 5, as shown in Figure 1.
The cylinder diameter of the cylinder body 1 is set to 50mm (tradition is 48mm), and the cylinder of cylinder body 1 is set to 66mm deeply, coordinates double scavenging air belts
Structure, so as to reach the purpose of lifting gasoline acc power and moment of torsion.
Optimize port timing size, combination property is improved with this, reduce piston ring scuffing, make burning more abundant, reach province
Oil, reduces the generation of carbon distribution, improves power durability, reduces maintenance amount：The lower bottom of the bore of air inlet 2 away from
Bottom from cylinder body 1 is 16.1mm, and the upper top of the bore of air inlet 2 is 28.1mm apart from the bottom of cylinder body 1；The exhaust outlet 3
The lower bottom of bore is 30.6mm apart from the bottom of cylinder body 1, and the upper top of the bore of exhaust outlet 3 is apart from the bottom of cylinder body 1
42.1mm；The bottom of height distance cylinder body 1 of first scavenging air belt 4 is 37.6mm, the bottom of height distance cylinder body 1 of the second scavenging port 5
For 37.1mm, as shown in Figure 1.
The two-stroke 1E50F gasoline engines of above-mentioned cylinder body 1 are configured, its parameter is set to：Combustion chamber volume is 6.8 ± 0.5cc,
Discharge capacity is 66.7CC, peak power >=2.2Kw/7000rpm.
The operation principle of the 1E48F gasoline engines is to open and close air inlet 2, exhaust outlet by the reciprocating motion of piston
3 and scavenging air belt, and then induction stroke, compression stroke, expansion stroke and exhaust stroke are completed, gas job step is as follows：
1st, piston stroking upward is in top dead centre, and air inlet 2 is opened, and exhaust outlet 3 and scavenging air belt are closed, the mixed gas in cylinder body 1
(compression stroke) is compressed, at the same time, the mixed gas produced by carburetor flows into the song of the bottom of cylinder body 1 from air inlet 2
Axle box (induction stroke).
2nd, spark plug 7 (on the cylinder cap 6 at the top of cylinder body 1) igniting, Mixed Gases Explosion promotes piston to move down (acting punching
Journey), exhaust outlet 3 and scavenging air belt are gradually opened (scavenging air belt is later than exhaust outlet 3 and opened) and air inlet 2 is progressively closed off, expansion
Burning waste gas discharge in (exhaust stroke), crankcase mixed gas through scavenging air belt from exhaust outlet 3 and enter cylinder body 1, air inlet it is same
When play a part of squeeze burning waste gas.
3rd, descent of piston is in lower dead center, and air inlet 2 is completely closed, and exhaust outlet 3 is opened completely, and piston stroking upward progressively closes off row
Gas port 3 and scavenging air belt and open air inlet 2, the mixed gas during piston stroking upward in compression cylinder 1.
4th, the negative pressure increase of crankcase, will suck crankcase by the mixed gas of carburetor.
