Problems solved by technology

[0003] The traditional diesel engine is limited by the structure, and the quality and kinetic energy of the intake air are insufficient, so that the diesel cannot diffuse rapidly in the combustion chamber to form a high-quality mixture, resulting in poor fuel economy and high emission levels of the diesel engine. It is an effective method to improve the above problems by improving the quality of temperament

Embodiment Construction

[0017] figure 1 , 2 , 3 shows the structure diagram and cross-sectional view of the first type of spiral auxiliary intake port 6. The gas passes through the first type of spiral auxiliary intake port 6 which spirals around the intake port 1, and is arranged near the intake valve seat 2. The first spiral auxiliary inlet port 6a of the first type of spiral auxiliary inlet enters the inlet port 1, and the connection between the inlet port 1 and the first type spiral auxiliary inlet port 6 adopts a smooth transition to reduce the energy loss of the gas flowing through here. The gas entering the combustion chamber 5 increases the momentum in the vertical direction of the axis of the combustion chamber 5, and the swirl intensity of the gas entering the combustion chamber 5 is obviously increased, which can quickly make the fuel and air form a more uniform mixture.

Abstract

The invention belongs to the technical field of diesel engine air inlet channel structural design and mixed gas forming, and discloses a spiral auxiliary air inlet channel of a diesel engine. The spiral auxiliary air inlet channel rotationally arranged around an air inlet channel is designed in order to improve the oil-gas mixing quality in a diesel engine combustion chamber and perfecting the combustion degree of diesel oil. After fresh air is converged into the air inlet channel through the spiral auxiliary air inlet channel, the air inlet quantity of each cycle of the diesel engine can be effectively increased, and the vortex intensity of gas entering the combustion chamber can be improved. In this manner, the combustion efficiency of fuel can be effectively improved, the fuel economic performance and discharge performance of the diesel engine can be improved, and the work section of the diesel engine can be expanded.

Description

Technical field [0001] The invention relates to a diesel engine spiral auxiliary air inlet, which belongs to the technical field of diesel engine air inlet structure design and mixed gas formation. Background technique [0002] Various countries and regions have formulated strict regulations on diesel engine fuel consumption limits. Users’ demand for high fuel economy of diesel engines is increasing day by day. At the same time, as the problem of air pollution becomes more and more serious, how to reduce harmful gas emissions from internal combustion engines has also been affected. There is more and more public attention, so how to improve the fuel economy of diesel engines and reduce the harmful gas emissions of diesel engines to meet strict emission regulations is a problem that must be solved by scientific research institutions and manufacturers. [0003] The traditional diesel engine is limited by the structure, and the intake quality and intake aerodynamic energy are insuffici...
