Problems solved by technology

Since the air enters the cylinder, it needs to go through two throttling, namely the throttle valve and the intake valve. The larger intake valve limits the size of the exhaust valve, which will cause a large air exchange loss.
Moreover, the app...

Abstract

The invention discloses an engine and a supply system thereof. The supply system of the engine comprises a first oil rail, a plurality of oil injectors, a first valve body, a second valve body, a second oil rail and a fuel tank, wherein the first oil rail is provided with a first inlet, a second inlet and a plurality of first outlets; each oil injector comprises a first entrance, a second entrance and an injection orifice, wherein the first entrances of the plurality of oil injectors are respectively connected with the plurality of first outlets; the first valve body and the second valve body are used for respectively opening and closing first and second entrances; the second oil rail is provided with a third inlet and a plurality of second outlets, wherein the second outlets are respectively connected with the second inlets and the plurality of second entrances; the fuel tank is connected with the second inlet. The supply system of the engine provided by the embodiment of the invention has the advantages of realizing premixing air and fuel oil, reducing gas exchange loss of the engine, improving the efficiency of the engine, simplifying the structure of the engine, reducing the cost and development difficulty of the engine and the like.

Description

technical field [0001] The invention relates to vehicle engineering, in particular to a supply system for an engine and an engine having the supply system for an engine. Background technique [0002] In the existing engine, the fuel reaches the fuel injector through the fuel rail, and then is sprayed to the designated position by the fuel injector. In order to enhance the power performance and charging efficiency of the engine, multi-valve and supercharging devices are used. In order to improve the charging efficiency at low and medium speeds and high speeds, VVT (Variable Valve Timing System) or variable intake manifold is required. Since the air enters the cylinder, it needs to go through two throttling, that is, the throttle valve and the intake valve. The larger intake valve limits the size of the exhaust valve, which will cause a large air exchange loss. Moreover, the application of supercharging device, VVT, variable intake manifold, multi-valve and other technologies...
