Abstract
The invention relates to an energy-saving two-stroke gasoline engine which has the following advantages: 1. an exhaust vent on a cylinder body is closed, and a fresh gas mixture can not be discharged to atmosphere when crankcase scavenged gas is rotated from a hole 3 to enter a cylinder, thereby saving energy and reducing exhaust pollution. 2. An exhaust valve is arranged in a combustion chamber, and therefore, local high temperature, poor lubrication and accelerated abrasion can not be created on the cylinder body, a piston and a piston ring in exhaust; after the exhaust vent generates carbon deposits, the exhaust time can not be delayed. 3. The gas mixture spirally rising is beneficial to lubricating the cylinder wall. 4. Residual waste gas in the cylinder is less than that in a four-stroke gasoline engine, therefore, the combustion is good, and lubricating oil in the gas mixture can be mostly burnt to apply work. 5. A crankshaft is provided with a cam and rotates 360 degrees to enable the exhaust valve to be opened and closed once respectively, and different opening and closing time cam be designed. 6. The cylinder wall does not have the exhaust vent, and therefore, the compression ratio can be properly increased a little and the effective working stroke can also be increased a little. 7. An air inlet can also be arranged on the wall of the crankcase, and the lubricating oil can be supplied by an oil pump according to rotating speed on time with unequal amount.
Description
Affiliated technical field
This energy-saving two-stroke gasoline engine relates to saves fuel oil, blowdown minimizing, durable, simple in structure, the background technique of machine.
At present, known two-stroke gasoline engine (crankcase scavenging) carburetor type, motor, three holes are arranged on the cylinder, these three holes can be closed by piston in certain moment respectively, hole one is communicated with Carburetor, inflammable mixture is one inflow crankcase through the hole, then can be through the hole three enter in the cylinder, waste gas then is discharged from through the hole two that is communicated with outlet pipe, because the relation of above structure, the shortcoming of two stroke engine maximum is to be difficult for getting rid of waste gas cleaner in cylinder, reduce effective working stroke during ventilation, and some fresh inflammable mixture is discharged from company with waste gas when ventilation, causes oil consumption, and is uneconomical, blowdown is serious, exhaust port two is on cylinder wall, cause local temperature seriously to increase, make cylinder, piston, the piston ring scuffing aggravation is behind the two mouthfuls of generations in the hole carbon distribution, period of exhaust is delayed, and machine Wen Zaidu increases.
Summary of the invention:
In order to overcome the shortcoming more than the existing two-stroke gasoline engine, this energy-saving two-stroke gasoline engine can overcome above shortcoming.
The technological scheme that its technical problem that solves this energy-saving two-stroke gasoline engine adopts is:
Make hole two (exhaust port) sealing on the cylinder body, an exhaust valve is installed in the firing chamber, the piston work done goes downwards to foramen primum two when opening, about 115 degree, exhaust valve in the firing chamber is opened, waste gas is discharged in the atmosphere through exhaust valve, outlet pipe, silencing apparatus, the incoming mixture that is subjected to precompressed three flows in the cylinders through the hole from crankcase, the mixed gas that flows in the cylinder rotates into cylinder screw type rising, cleaning waste gas, gas exchange process accounts for the crank angle final vacuum door of 130 degree greatly and closes, and then piston continues upwards, just the repeated compression process is carried out new circulation.
Effective effect of this energy-saving two-stroke gasoline engine is:
Incoming mixture can not arranged (saving fuel oil) in the atmosphere when 1, taking a breath.
2, cleaner in the waste gas discharge cylinder, the interior residual gas ratio four stroke engine of (blowdown minimizing) cylinder is few fully in burning.
3, cylinder body, piston, piston ring are heated evenly and alleviate wearing and tearing.
4, manufacturing is also fairly simple.

Energy-saving two towards petrol engine
2, improve back 1-inlet hole 2-exhaust port 3-transfer port.
Claims (2)
1. a two-stroke gasoline engine has three holes on cylinder, and hole one is connected with Carburetor, and inflammable mixture one flows into crankcase through the hole, then can be through the hole three enters in the cylinder, and waste gas then can be discharged from the atmosphere through the hole two that is communicated with outlet pipe.
It is characterized in that: close closed pore two (exhaust port), an exhaust valve is installed in the firing chamber, cam of crankshaft installed, crankshaft rotating 360 degree make the exhaust valve switch respectively once.
2. two-stroke gasoline engine according to claim 1
It is characterized in that: the inflammable mixture in the crankcase, to rotate into rear screw rising cleaning waste gas in the cylinder.
