Abstract
An engine cylinder body with an auxiliary air inlet channel features that it has a central through chamber of piston, the exhaust channel, air inlet channel and auxiliary air inlet channel on side wall, which are communicated with the piston chamber, and several heat-radiating ribs on its external surface. Its advantages include high fuel efficiency, less environmental pollution of waste gas and saving oil.
Description
The invention belongs to the internal-combustion piston engine parts, particularly a kind of engine cylinder body with auxiliary air inlet channel.
As shown in Figure 1, for motor vehicle engine cylinder that comprises cylinder block, cylinder head and piston of current mobility, its cylinder block are provided with piston chamber and reach exhaust passage and the gas-entered passageway that is communicated with piston chamber.Wherein, gas-entered passageway all is to utilize cylinder block casing wall thickness to form the closed shape gas-entered passageway.The import that is gas-entered passageway is penetration state with outlet system, and does not have any auxiliary giving vent to anger or the slotted eye of exhaust fast.Not only easily because of exhaust velocity influences fuel efficiency slowly, and also cause vehicle oil consumption and waste gas to increase, aggravation is to atmospheric pollution.
In addition, engine cylinder cognition causes the piston obturation.Its reason causes the cylinder block temperature too high nothing more than because of the piston indoor exhaust air accumulates, and again because of the piston to-and-fro motion friction produces in piston chamber high heat, makes piston Yin Gaowen and is out of shape, so that form the inaccessible phenomenon of piston as previously mentioned, causes damaging cylinder block.
The purpose of this invention is to provide a kind ofly improve fuel efficiency for engine, reduce exhaust emission pollution, the engine cylinder body with auxiliary air inlet channel of fuel-efficient and protection environment.
Central authorities of the present invention are provided with the piston chamber of perforation, and its sidewall is provided with exhaust passage, gas-entered passageway and the auxiliary air inlet channel that is communicated with piston chamber.Its periphery is provided with plural cooling fin.
Wherein:
The open shape passage that auxiliary air inlet channel system utilizes cylinder block casing wall thickness to form, the import of auxiliary air inlet channel with export between be provided with the slotted hole that is communicated with piston chamber.
The entrance point of gas-entered passageway and auxiliary air inlet channel extends the ring wall that inwall is connected with the piston chamber inwall, and all establishes the through hole that plural number is communicated with piston chamber on ring wall.
Because central authorities of the present invention are provided with the piston chamber of perforation, its sidewall is provided with exhaust passage, gas-entered passageway and the auxiliary air inlet channel that is communicated with piston chamber.Its periphery is provided with plural cooling fin.During assembling, will pack in the piston chamber of the present invention with the piston that crank articulates.Cylinder head is fixedly mounted on top of the present invention.When engine cylinder is worked; with auxiliary air inlet channel; accelerate gas and enter the speed that piston chamber and waste gas are discharged from the exhaust passage, not only can improve fuel efficiency and engine power, reduce waste gas and produce; compliance with environmental protection requirements; and stop to cause the too high phenomenon of temperature to take place because of waste gas accumulates, reduce and take place inaccessible phenomenon takes place between piston and the piston chamber, not only can improve fuel efficiency, fuel-efficient; and reduce exhaust emission pollution, protection environment, thereby reach purpose of the present invention.

Elaborate under below in conjunction with accompanying drawing the present invention being advanced.
As Fig. 2, Fig. 3, shown in Figure 4, central authorities of the present invention are provided with the piston chamber 1 of perforation, and its sidewall is provided with exhaust passage 2, gas-entered passageway 3 and the auxiliary air inlet channel 4 that is communicated with piston chamber 1.Gas-entered passageway 3 is the closed shape passage that utilizes the present invention's week wall thickness to form, and the import 31 of gas-entered passageway 3 is the sealing penetration state with outlet 32.Auxiliary air inlet channel 4 is to utilize the present invention week open shape passage of forming of wall thickness, the import 41 of auxiliary air inlet channel 4 with export 42 between be provided with the slotted hole 43 that is communicated with piston chamber 1.Periphery of the present invention is provided with plural cooling fin 5.Extend the ring wall 6 that inwall is connected with piston chamber 1 inwall in import 31,41 ends of gas-entered passageway 3 of the present invention and auxiliary air inlet channel 4, and on ring wall 6, all establish the through hole 7 that plural number is communicated with piston chamber 1.
During assembling, as shown in Figure 5, the piston 9 that will articulate with crank 8 is in the present invention bottom is packed piston chamber 1 into.
As shown in Figure 6, cylinder head 10 is fixedly mounted on top of the present invention.As Fig. 6, Fig. 7, shown in Figure 8, when engine cylinder is worked, with simultaneously to export 42 and the open shape auxiliary air inlet channel 4 that is communicated with piston chamber 1 of slotted hole 43, accelerate the speed that gas enters piston chamber 1, not only can improve fuel efficiency and engine power, and minimizing waste gas produces compliance with environmental protection requirements.
When accelerating intake velocity, also accelerate the speed of waste gas 2 discharges, stop to cause the too high phenomenon of temperature to take place because of waste gas accumulates from the exhaust passage.Through hole 7 cools off piston 9 with gas or oil on ring wall 6, uses direct reduction piston 9 temperature, prevents that piston 9 from producing high temperature and be out of shape.Inaccessible phenomenon takes place to take place between piston 9 and the piston chamber 1 thereby reduce.
Characteristics of the present invention are to be provided with auxiliary air inlet channel 4. The import 41 of auxiliary air inlet channel 4 with Outlet is provided with the long slot bore 43 that is communicated with piston chamber 1 between 42, has that air inlet is fast, efficiency of combustion is high, province The advantage of oil and protection of the environment.
Another characteristics of the present invention are in the import 31 of its inlet channel 3 and auxiliary air inlet channel 4,41 ends Extend the ring wall 6 that inwall is connected with piston chamber 1 inwall, and on ring wall 6, all establish plural number and connect with piston chamber 1 Logical through hole 7. Can on ring wall 6, cool off piston 9 with gas or oil by through hole 7, use to reduce and live Fill in 9 temperature, avoid the advantage of piston 9 distortion.
