Abstract

The invention provides a diesel engine intake manifold structure applied to the technical field of diesel engine intake systems. Each tangential airway (2) and each spiral airway (3) of the diesel engine intake manifold structure align at an air inlet of one air cylinder of a diesel engine; a rotary shaft (4) penetrating through multiple spiral airways (3) at the same time is arranged on an intakemanifold body (1); an eddy reverse turning bed (5) arranged on the rotary shaft (4) is arranged in each spiral airway (3); and a drive motor (6) is arranged on the intake manifold body (1), is connected with the rotary shaft (4) through a control rod (7), and is connected with a control part capable of controlling the drive motor (6) to start and stop. According to the diesel engine intake manifold structure provided by the invention, the adjustability in air intake is realized, the problems of insufficiency in oil-air mixing and low high-speed intake efficiency occurred when an engine runs at low load and low speed are effectively solved, the oil consumption is reduced, the output power of the engine is improved, and the working performance of the engine is improved.

Description

technical field [0001] The invention belongs to the technical field of diesel engine intake systems, and more specifically relates to a diesel engine intake manifold structure. Background technique [0002] In modern internal combustion engines, especially in the working process of small and medium-sized high-speed diesel engines, the intake vortex movement plays a very important role. The air intake system of a diesel engine generally adopts a four-valve combined intake port with a tangential port and a spiral port. The vortex generated by the tangential port is a one-sided air flow passing through the valve port, and is affected by the air flow above the valve seat. The sharp throttling effect of the passage part, combined with the eccentric arrangement of the air passage itself, is produced by the comprehensive effect, which is very suitable for the cylinder charge, moderate or small rotation speed, and the medium and high vortex is generated by the spiral air passage.
