Abstract

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 one dimensional simulation modeling of engines provides important theoretical and practical guidance for optimization in actual production processes.
