Description

Improvement of booster cylinder for vehicle air intake structure

technical field

The utility model relates to a vehicle air intake structure, in particular to an improvement of a booster tube of the vehicle air intake structure which introduces gas to enhance the air pressure in the combustion process of an engine.

Background technique

The mixed combustion of oil and air of the engine must rely on the air provided by the intake manifold, which is located between the throttle valve and the engine intake valve, because after the air enters the throttle valve, the air is introduced into each valve separately through the intake manifold. in the cylinder. In addition, in the braking device, using human power to press down the brake pedal can not get a good braking performance, so many vehicles are additionally equipped with a vacuum brake assist. The principle is that when the brake pedal is removed, it also The vacuum pump pipeline on the intake manifold is used to open, and the vacuum suction of the intake manifold is used to increase the braking force, and the suction also sucks the air in the braking system at the same time.

From the above two systems, it can be found that the problem of the fuel-air mixed combustion of the above-mentioned engine is that the vehicle often does not have sufficient and complete combustion, such as insufficient air intake, resulting in insufficient air as a combustion condition, thus resulting in fuel consumption. Problems with air pollution. Although the air absorbed by the aforementioned braking brakes also provides corresponding air for the intake manifold, the air absorbed by the braking brakes is still insufficient.

Known, although there is the announcement No. 553313 "intake structure improvement of automobile and motorcycle" in Taiwan, China, although a booster tube is set between a brake assist device and an air collection box, the booster tube is connected to the engine by the booster tube. At the same time, the ignition sequence of the main body sucks air into the filter layer for filtration, and then flows from the air intake hole of the intake pipe through the air stone to the joint sleeve and then flows to the air collection box, although more air can be provided to assist the engine body to burn completely.

But in fact, the engine combustion process still has incomplete combustion and carbon deposits. The carbon deposits are often caused by incorrect air-fuel. According to the theoretical air-fuel ratio of a gasoline engine is 14.65:1 (that is, 14.65 parts of air: 1 portion of gasoline), and because of the carbon deposit, the throttle valve is stuck, so when the accelerator is released, the throttle valve cannot be completely closed, and there is some opening, which leads to an increase in idle speed. However, from the perspective of the prior art, it still fails to fully solve the phenomenon of improper air-fuel.
