The structure design of the utility model can improve an engine combustion chamber to cause air to be intaken more sufficiently so as to achieve complete combustion of the gasoline mixture in the combustion chamber, improve the horse power and the torque output of the engine, and decrease carbon deposit occurrence in the combustion chamber and the emission of carbon monoxide CO, hydrocarbon compound HC, nitric oxide NOx, etc. in exhaust air, ultimately, to achieve the practical structure with more conformability to the environmental protection requirement and conservation of fuel and cost.

Description

The engine air admittance vortex structure

Technical field

The utility model relates to a kind of engine air admittance vortex structure, can be common to internal combustion engine gas handling system (such as automobile, locomotive, generator, boats and ships, mowing machine etc.), can make the gasoline mixture perfect combustion that improves in the more sufficient and firing chamber of engine combustion chamber air inlet, the while more can compliance with environmental protection requirements and the structure of fuel saving expense.

Background technique

The design of general vehicle traditional standard type engine intake, engine combustion is indoor often because of deficiency of air under long-time the use, cause and to reach perfect combustion and have influence on the indoor gasoline mixture of engine combustion, so the design of advanced modified model engine intake is arranged, it improves structure high flow capacity air-core, high flow capacity metal-air core, electric booster, photoelectricity pressurized machine, rotation dynamic formula pressurized machine ... Deng.

The air-core of former car engine intake, through changing the outfit into the high flow capacity air-core, high flow capacity metal-air core, suck speed air flow to increase, but the air-core filter screen density of its shortcoming because of changing the outfit, can change the suction speed air flow with the dust silt that sucks, need often do air-core cleaning or replacing.

Electric booster is installed in the air intake filter case, utilize electronic control motor rotary speed to reach the effect of forcing air inlet, making engine intake suck speed air flow can keep normally, this rotation dynamic formula pressurized machine is installed in the suction tude between air intake filter case and air throttle, utilize the moving air amount of inlet air to suck speed air flow to increase engine intake, its shortcoming is that the moving air amount of inlet air is uncontrollable.

In addition, photoelectricity pressurized machine; Install a slice chemical fibre on the air filtering core additional, the oxygen content of inlet air is improved, its shortcoming also can't increase engine intake and suck speed air flow, and its disadvantage is that engine intake is too fast because of the flowing velocity of inlet air, cause the former inlet air flow perceptron of change and do the judgement that makes mistake, easily cause the fuel delivery that increases the engine oil spout, thereby produce engine oil consumption phenomenon, directly have influence on function and the quality that the back product uses is installed.

Summary of the invention

The utility model designer is because the above-mentioned engine intake air pressurizing unit of commonly using, existing increase air inlet amount causes oil supply system variation shortcoming too greatly, study general internal combustion engine design in great detail and all come the fuel injection quantity (the most economical sky of common theoretical desirable empty combustion proportions of ingredients 14.7: 1 (weight calculating) fired proportions of ingredients 16: 1 to 18: 1) of Control Engine oil-fired system with air flow amount, practise the existing shortcoming of formula person at each money and studied improvement again, improve situation through the durable test that travels of car engine between long-term, finish structural design of the present utility model finally.

Main purpose of the present utility model is, exempt from maintenance and utilize air flows to produce the air swirl phenomenon after providing a kind of and have air mass flow that nature increases engine intake, installing, by increasing the suction pressure of engine, make the more smooth energy of engine air admittance suck more air, can make the indoor gasoline mixture of engine combustion reach the engine air admittance vortex structure of perfect combustion benefit.

For reaching aforementioned purpose, the technical solution of the utility model is: a kind of engine air admittance vortex structure is provided, mainly on the internal combustion engine gas handling system, has an air swirl pressurized machine, it comprises: an exterior cylinder, one inner cylinder body, be provided with in the middle of this inside and outside cylindrical body several fixedly guide vane to be connected; Wherein each fixed guide vane designs through special angle, its wheel blade is arranged be radiation to extend shape, and by this, can producing eddy current when making air inlet naturally, to quicken to reach the air inlet that increases engine more smooth and easy.

The utility model can use for a long time, has the air inlet of making system engine combustion chamber air inlet effect more smoothly, the eddy current that is produced also can promote flame moment rate of propagation, the gasoline mixture combustion position that can reach the engine combustion chamber is more stable, to strengthen the thermal efficiency of engine combustion, and then the output that improves engine torque, horsepower, reduce carbon monoxide CO, hydrocarbon HC in the waste gas, the discharging of nitrogen oxides NOx etc.

For further understanding constitution content of the present utility model and characteristics thereof, lift the utility model now than specific embodiment, and cooperate the following drawings to be described in detail as follows:
