Problems solved by technology

The current intake system structure, in order to take into account the high and low speed performance, selects the intake port structure with a large flow coefficient and low tumble ratio, so the combustion duration is longer and the thermal efficiency is lower.

Embodiment Construction

[0010] The variable section and tumble flow air intake system of the present invention includes an intake manifold and a cylinder head intake port structure. The intake manifold has a layered double-layer structure from the plenum chamber to each branch pipe. There is a rotating valve plate in the plenum chamber, which can rotate at different angles according to different working conditions; The air passage is divided into upper and lower layers, which cooperate with the layered structure of the intake manifold. The cylinder head is also equipped with intake and exhaust valves, intake and exhaust ducts, and intake and exhaust seat rings; the fuel injector can be installed in the intake passage. Below or above, depending on the jetting method.

[0011] Under low-load conditions, the rotary valve of the intake plenum chamber does not rotate, and the airflow can only pass through the intake manifold and the upper layer of the intake port. The bottom surface of the exhaust valve ...

Abstract

The invention discloses a novel variable-section tumble air intake system. According to the system, by changing the air intake section of each air intake manifold under the low-load working condition, the air intake flow speed is increased, the air intake tumble ratio is increased in cooperation with an air inlet partition, the wall wetting phenomenon of a cylinder liner, the piston top face and a valve due to fuel oil injection in a cylinder is lowered, carbon deposition is reduced, the emission is lowered, the oil dilution rate is lowered, the uniformity of mixed gas is improved, and the fuel economy is increased. At a high load, by adjusting the air intake section, the air intake resistance is lowered, the sufficient air inflow is provided for a generator, and the requirement of a whole vehicle for the large power of an engine is guaranteed.

Description

technical field [0001] car engine air intake system Background technique [0002] With the increasingly stringent environmental protection and emission regulations and the increasing requirements of consumers on the fuel economy of automobile engines, how to meet the low emission and high fuel economy of automobile engines has become a problem that must be solved in the automotive industry. It is a current research goal to develop a vehicle engine that has the advantages of low emission of gasoline engine and high fuel economy of diesel engine at part load. [0003] For the side-mounted direct injection gasoline engine, due to the side-mounted injector, the oil beam and the cylinder bottom plane are inclined downward at a certain angle during the fuel injection process. Under lower working conditions, the spray will inevitably collide with the cylinder wall and the top surface of the piston, resulting in carbon deposition, oil dilution, and emission deterioration. Therefor...
