Abstract

The invention relates to a pump-nozzle-tube integrated electric injection valve with a centrifugal nozzle. The electric injection valve comprises a casing, a driving coil, a driving plunger, a valve body and the centrifugal nozzle component. The driving coil is arranged inside the cylindrical casing; the valve body is arranged in the central hole of the driving coil; the driving plunger is arranged inside the valve body; and the centrifugal nozzle component is arranged on the front end of the valve body. When the fuel oil is discharged out of the centrifugal nozzle component after rotation and acceleration, the fuel oil thin film is atomized through tearing and collision with air and is rotated into a cylinder, so that the fuel oil thin film is evenly mixed with the air. As the fuel oil is atomized and is further evaporated into smaller fog particles through the enlarged fuel oil flow in the cylinder due to rotation, the oxygen contact combustion area of the fuel oil is greatly increased; the combustion efficiency is greatly improved; and the formation of carbon deposit and harmful substance is reduced.

Description

technical field [0001] The invention relates to the main action mechanism of the oil control part of the gasoline engine, the diesel engine and the electric injection system of the motorcycle engine, in particular to an integrated electric injection valve with a pump nozzle and a centrifugal nozzle. Background technique [0002] With the increasingly stringent emission regulations, as one of the main technical means to meet the Euro II, Euro III, and Euro IV emission regulations, motorcycle EFI will be an inevitable trend in the development of the motorcycle industry in the future, and it is also the participation of Chinese motorcycle companies. A core technology that must be mastered in international and domestic market competition, the key to adopting EFI technology is to reduce the cost of EFI system. [0003] The EFI system perceives various working conditions and environmental changes as well as the rider's intentions through different sensors, and provides the engine ...
