“…Few researchers have analyzed and researched the intake pipe before and after the implementation of the air filter [27][28][29]. In their latest research, Xie analyzed the intake performance of a certain type of intake pipe, optimizing the air intake by adjusting the bending curvature and setting a guide groove at the inlet [30]. Subsequently, the optimized model was verified through simulation but not through physical experiments.…”

As the front end of the intake system, the intake dirty pipe is responsible for delivering sufficient and stable air to the air filter. Therefore, in order to meet the requirements of low intake resistance, it is necessary to correspondingly improve the flow resistance performance of the intake dirty pipe. In this study, the main research object was the intake pipe in the intake system of gasoline engine vehicles, and the internal gas flow field was simulated and analyzed. The results show that there are clear discrete velocity regions at the inlet and elbow, which affect the uniformity of the overall fluid flow and cause a certain pressure loss. After structural optimization, the total pressure difference at the inlet and outlet of the pipeline was reduced by 22.67% compared to the original model, and the total pressure loss was significantly reduced. A simplified model was used to make samples of the intake dirty pipes before and after performance improvement, and flow resistance tests were conducted respectively. The difference between test data and simulation data is within a reasonable range, and the simulation results are relatively reliable.

“…Fluid mechanics is a discipline gradually formed in the process of using fluids. It originated from Archimedes' research on buoyancy, and developed because of the mutual promotion between mathematical and fluid engineering disciplines [1]. Now it has become one of the foundations of aerospace, vehicle, machinery, environmental biology and other engineering disciplines.…”

With the continuous innovation and progress of automobile technology, people have put forward higher and stricter requirements on the safety and environmental protection of automobiles. Therefore, the air resistance, surface pressure, aerodynamic lift, aerodynamic side force and other mechanical problems must be considered comprehensively in the design of automobiles. Fluid mechanics is the study of the motion of gases and liquids under the action of various forces and the application of the discipline. All objects moving in the earth's atmosphere are affected by fluid mechanics, so fluid mechanics has a very important guiding significance to the design of vehicle. This paper is mainly aimed at the influence of air resistance on the performance of the car, the fluid mechanics Angle analysis of the role of the car streamlined design, the principle of the car streamlined body, the shape of the streamline several aspects of the comprehensive introduction of fluid mechanics in the car body design application.

The purpose of this article is to investigate optimization methods for engine intake manifolds to improve air intake efficiency and reduce pressure losses. By using AVL BOOST software for one-dimensional simulation modeling, the influence of different intake manifold structure parameters on engine performance can be quickly evaluated, providing guidance for optimization in actual production.Firstly, a one-dimensional simulation model of a dual-fuel engine was established using AVL BOOST software, and the model was initially set using bench test report data. Then, the simulation accuracy under different load conditions was verified to ensure an error of less than 5%. Based on this, the structure parameters of the engine intake manifold were optimized to obtain the best air intake performance.Through simulation result analysis, we found that the optimal intake pipe length is 160mm, the optimal pipe diameter is 150mm, and the optimal intake manifold volume is 110L. These optimized parameters significantly improved major performance indicators such as cylinder torque, volumetric efficiency, and mechanical efficiency.The optimized dual-fuel engine showed improved performance in major parameters and a reduced brake specific fuel consumption, indicating significant optimization effects of the engine intake manifold. Therefore, studying onedimensional simulation modeling of engines provides important theoretical and practical guidance for optimization in actual production processes.
