Intake manifold and fuel injector mounting system

Abstract

The invention discloses an intake manifold and a fuel nozzle installation system, which comprises an engine (4), and a combustion chamber mouth valve housing ( a), the fuel nozzle (2) is fixed on the intake manifold (1) close to the combustion chamber port valve compartment (a), and it is characterized in that: the fuel nozzle (2) faces the combustion chamber port valve compartment (a), and the extension line of the center line of the fuel nozzle (2) intersects with the center line of the combustion chamber port valve compartment (a), and the center line of the combustion chamber port port compartment (a) is installed on the engine (4 ) on the valve (3) and the axial center line of the valve stem (5) on a straight line. The remarkable beneficial effect is that it can ensure that the oil and gas ejected from the fuel nozzle can be directly sent into the combustion chamber of the engine, avoiding the phenomenon of wet wall of the intake manifold, and ensuring that the fuel can be fully burned.

Description

technical field [0001] The invention belongs to the technical field of fuel injection technology of fuel injection motorcycles, and in particular relates to an installation system of an intake manifold and a fuel nozzle. Background technique [0002] Existing EFI motorcycles all install the intake manifold on the intake port, forming a valve chamber at the intersection of the engine and the combustion chamber, and fixing fuel oil on the intake manifold close to the valve chamber at the mouth of the combustion chamber. Nozzles, fuel nozzles inject vaporized fuel into the intake manifold, and install valves in the valve housing of the engine. The valves are connected to the valve stem. With the operation of each stroke of the engine, the valve rod pulls the valve to move at the valve housing. The opening and closing of the intake port of the combustion chamber is realized. When the engine enters the intake stroke, the valve leaves the valve chamber, the intake port of the comb...

AI Technical Summary

Problems solved by technology

[0003] But the shortcoming of prior art is: the fuel injection nozzle is just simply fixed on the intake manifold, or towards the intake manifold, or towards the valve and the valve stem, or towards the engine, and its fuel injection time is not controlled, often After the valve blocks the inlet of the combustion chamber, the fuel nozzle is still injecting fuel. At this time, the fuel gas is often injected onto the inner wall of the intake manifold and the valve stem, forming the wet wall phenomenon of the intake manifold.
