Oil-way oil supply system used in direct injection engine

Abstract

The invention discloses an oil supply system for a direct-injection engine. An iron core is arranged in the fuel injector body, and an electromagnetic coil is sleeved on the iron core. A nozzle cover is provided, a sealing ring 1 is sleeved on the outer wall of the nozzle cover, a valve seat is provided in the limit sleeve, the valve seat is connected to a valve plate, and a second pressure sensor and a second temperature sensor are provided in the injector body; The fuel injector is provided with a mounting sleeve, a protective sleeve is provided in the mounting sleeve, a pressure regulating slider is provided in the protective sleeve, a spring is connected to the pressure regulating slider, and the spring passes through the opening of the protective sleeve to connect with the valve plate, and the protective sleeve is provided with a There is a first pressure sensor and a first temperature sensor. The system can understand the internal operating conditions of the fuel injector, and can deal with some potential minor problems in time to prevent them from expanding. It also reduces the probability of clogging during the fuel injection process, improves fuel injection efficiency, and prolongs the service life.

Description

technical field [0001] The invention relates to a system, in particular to an oil circuit oil supply system for a direct injection engine. Background technique [0002] Automobile is a vehicle that can be driven by its own power, and can be driven by motor without the need for rails or electric power. In a broad sense, a vehicle with four wheels is generally called a car. From the end of the 19th century to the beginning of the 20th century, car designers focused their energy on the design of cars. mechanical engineering The development and innovation of learning. In the first half of the 20th century, after the basic structure of the car had been invented, car designers began to improve the exterior shape of the car, and successively introduced aerodynamics, fluid mechanics, ergonomics and industrial design (industrial design). Aesthetics) and other concepts, and strive to make the car meet the different needs of people of various ages, classes, and even cultural backgro...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the complex structure of the fuel injection device of the existing automobiles, which often causes the fuel injection nozzle to be blocked, resulting in poor fuel injection efficiency and high maintenance costs, and the user cannot understand the internal state of the fuel injector and cannot timely To deal with some potential small problems, an oil supply system for direct injection engines is designed. By improving the structure, the system enables users to understand the internal operating conditions of the injectors and deal with some problems in time. Potential small problems can be prevented from expanding, and the probability of clogging during the fuel injection process can be reduced, fuel injection efficiency can be improved, and the service life can be extended. The fuel injection efficiency is poor, the maintenance cost is high, and the user cannot understand the internal state of the fuel injector, and cannot deal with some potential minor problems in time
