Description of the Invention: [Technical Field] The present invention relates to an engine intake air conditioning system and apparatus, which are capable of allowing air to enter an engine via an auxiliary air cleaner when the engine is accelerating The intake manifold allows the oil/gas ratio to be closer to the ideal value. [Prior Art] * As shown in Fig. 1, the conventional engine intake path includes introducing air from a gas purifier 6 through the air duct 7, the engine intake manifold 3, mixing with the fuel, and being sucked into the engine by the piston. Room 4. The flow meter (brain) 8 ® Xiao Zeqing air duct generates a signal at the flow rate, and the fuel age control system 9 can control the fuel injection amount according to the signal given by the flow meter 8, so that the most economical oil can be maintained at least at idle speed. / gas mixing ratio, for example, to maintain the oil / gas mixture ratio of ljl5. Some of the engine crankcases 5 below the spleen combustion chamber 4 introduce exhaust gas into the intake manifold 3', and the breather hoses 52 are connected to the air duct 7 to communicate with the atmosphere, thereby maintaining the operation. The pressure inside the box is balanced. Since the exhaust gas of the engine combustion chamber 4 is inevitably leaked to the engine crankcase 5 through the piston (the gas contains harmful gases such as hydrocarbons (HC) and oxidized (C0)), in order not to be directly discharged into the atmosphere. The exhaust gas from the engine intake must be used to introduce these exhaust gases into the engine intake manifold 3 and again into the engine combustion chamber 4 for combustion. In the past, countries have specified that the engine must be equipped with a cv (smuggling ❹ Crankcase Ventilation Valve) valve 51, so that these harmful health hydrocarbons (CH) and carbon oxides (c〇) are reburned. Avoid direct air pollution and air pollution. In actual operation, the conventional engine still has the following shortcomings, which need to be improved: 1. Since the breathing hose 52 communicates with the air duct 7, the engine piston will downwardly compress the air-air in the crankcase 5 when descending. The oil vapor in the tank is forced into the air duct 7, and when it encounters cold air, it condenses on the pipe wall, causing the oil pipe 7 to cause oil collapse pollution that cannot be removed. 2. The engine's intake and injection design can only achieve a 1:15 economical oil/gas mixture ratio at idle. At the moment of sudden acceleration and driving on the accelerator pedal, the existing air intake system cannot immediately replenish a sufficient amount of air. At this time, the oil/gas mixture ratio will be too rich to be completely burned, resulting in fuel consumption and air pollution. SUMMARY OF THE INVENTION 4 200936873 In order to solve the problem that the air cannot be immediately replenished when the engine is accelerated, the present invention provides an engine intake air conditioning system including an adjusting device and an auxiliary air filter. The adjusting device is connected between the air filter and the engine intake manifold, and the suction force when the engine is accelerated is suddenly increased, so that the outside air can enter the engine intake manifold from the auxiliary air filter, thereby accelerating the complementing engine. The sudden increase in air demand during acceleration.

This embodiment is such that the unit air flow rate allowed by the thin air vent 18 is much smaller than that of the rough air vent 16, so that when the engine is accelerated, the intake air amount and the suction force are suddenly increased, so that the pressure in the second space 15 is relatively larger than the first. The space 14 is thus moved toward the first space 14 in the diaphragm u. The housing 10 is provided with a gate 14 in the first space 14 and is openably connected to the valve member 12. The first spring 131 is disposed in the housing 10 for keeping the valve member 12 in close contact with the gate 14 for intercepting the gas passage between the rough air vent 16 and the air inlet 17 when the engine is not speeding or idling. . As shown in Fig. 4, the valve member is connected to the diaphragm u in the first space 14. When the engine accelerates, the sudden increase in suction of the engine intake manifold 3 causes the diaphragm 丨丨 to compress the __spring 131 force and move toward the _ space 14 ,, thereby pushing the door 7C member 12 to open the aforementioned gas passage, allowing The outside air & gas is filtered from the lion air filter H 2. The gas passage in the regulator 2 and the intake manifold 3 are sucked into the engine combustion chamber 4 to help burn. The implementer can tamper with the adjustment device shown in Fig. 3 as a modified embodiment as shown in the fifth embodiment. In this embodiment, a second spring 132 and a second adjustment button are added to the second space 15, and a second air button 18 is formed in the second adjusting button 180.

In this embodiment, the first-adjustment button m is added to the first-to-find 14 and an intake port 170 is provided at the first adjustment button i7Q. In this embodiment, the relative position of the first adjustment (four) and the second adjustment button 180 can be adjusted, the balance position thereof is changed, and the tightness between the valve member 12 and the closed port 140 is adjusted to ensure that the diaphragm pushes the valve when the engine accelerates. Element 12 opens gate HO. The implementer can also adjust the adjustment device shown in Figure 3! Change to the modified embodiment as shown in Fig. 7. This embodiment - in the second space 15 is added - a third adjustment button _, including - the shank face with the end laterally entering the thin air vent 191 of the second space 15. The third embodiment of the shank is provided with a screw thread. The ventilating performance of the thread 1_section reducing hole 191 can increase or decrease the force of the diaphragm 11 moving toward the first space 14 during fresh acceleration. Turning on the force that pushes the door member 12 to open the closing device is adjusted to an appropriate size to accommodate the operation of different engines. In addition, those skilled in the art can change according to the adjusting device i shown in Fig. 6. For example, the following 6 = 200936873 has the following engine providing air intake adjusting_° device, when compared with other technologies, at least 1. At the heart rate, the spring of the Ip device makes the _ component get the path of the mouse, so * will affect the preset optimal oil/gas mixture ratio; and when the engine is accelerating, immediately above and below the diaphragm U The pressure difference is created and the gas passage is automatically opened, and the air is sucked from the auxiliary air cleaner 2 to accelerate the filling, reducing the concentration of the oil/milk mixture and making the combustion more complete.
