Problems solved by technology
The smaller the fuel injection hole, the better the atomization effect. If the diameter of the fuel injection hole is less than Φ0.2mm, the atomization effect will be better, and the engine performance will also improve, with more fuel-efficient and cleaner emissions, but the fuel injection must be done It is very difficult for the hole to be below Φ0.2mm in diameter
Due to the limitation of the diameter of the fuel injection hole, the atomization method of the fuel injection hole is not easy to improve the atomization effect of the fuel.

The invention provides a fuel nozzle atomizer and a fuel atomizing injection device for the automobile engine, which has better pulverization effect. The fuel atomizing device adopts the forms of single point injection and multi-point injection. The technical proposal is that the nozzle is designed with the changeable spraying clearance, which is in accordance with the size of the throttle valve to realize synchronous stepless positive control, as the size of the spraying clearance changes along with the degree of openness of the throttle valve; the nozzle is provided with a compressed air inlet, so the fuel is ejected out from the circular spraying clearance via the negative pressure inspiration formed by the compressed air or via an electric pump; the compressed air is mixed with the fuel and is pulverized and then is mixed for a second time with the air inlet from the throttle valve. The fuel nozzle atomizer and the fuel atomizing injection device for automobile engine of the invention is capable of achieving the optimal pulverizing effect, ensures intensive mixing of the fuel, and is mainly applied to gasoline engine.
Description
technical field [0001] The invention belongs to an atomization injection head of a fuel atomization injection device for an automobile engine and a fuel atomization injection device using the injection head. Background technique [0002] Since the advent of automobiles, the carburetor has always been the oil supply atomization device for the engine. Its structure is relatively simple. Inadequate, gas guzzling, poor emissions, now out. At present, the manufacturer has launched the second generation of electronic injection, which is often called "electronic injection". Its advantages are good start-up performance, more fuel-efficient than carburetors, and emissions up to Euro 2 and Euro 3 standards. Its characteristic is that its atomization effect and air-fuel ratio control are better than carburetors. Several technical elements in EFI: 1. The diameter of the fuel injection hole of the injection head is between Φ0.4mm and Φ0.6mm, which is invariable; 2. The air-fuel ratio c...
