Modelling and Simulation Analysis of High-Pressure Common Rail and Electronic Controlled Injection System for Diesel Engine

Abstract

The electronically controlled fuel injection system of the diesel engine has multi-disciplinary characteristics and strong coupling. The programming method based on a mathematical model cannot be applied to the fuel system with a diversified structure arrangement. With the rapid development of hydrodynamics, more and more simulation software is applied in the actual research. Hydsim simulation platform is one of the best software for the simulation of the electronic control injection system. In this paper, the Hydsim simulation platform is used to simulate the electronic control injection system, and a test-bed for verification is built. Based on the experimental results, the injection characteristics of high-pressure common rail are studied. The validity and accuracy of the simulation model are verified by comparing the simulation value with the test value and the standard value. Finally, the influence of the structural parameters such as the inlet and outlet orifices and control pistons of the injection system on the injection characteristics is analysed, and the selection principle of each parameter in the system design is proposed, which provides a reliable basis for the structural optimisation.

Computational Intelligent Paradigms to Solve the Nonlinear SIR System for Spreading Infection and Treatment Using Levenberg–Marquardt Backpropagation

“…In future, the LMB designed neural network may be explored for the bioinformatics systems [39][40][41], fractional order systems [42,43], system of nanofluid models [44][45][46][47] and higher order system of equations [48][49][50][51][52]. Additionally, the proposed LMB neural network methodology can be implemented for SIR-based infection spread dynamical models involving high nonlinearity, stiffness, singularities, and delay differentials for the analysis of the models, which still remain challenging traditional/conferential numerical methodologies.…”

Nonlinear Differential Equations in the Teaching Model of Educational Informatisation

“…dY 3 can be obtained by formula (4). Then suppose that the finite series form of Y (ξ ) can be expressed by u(ξ ).…”

“…The key to research teaching is the design of the research teaching plan. 'Ordinary differential equations' is a professional introductory course for mathematics and applied mathematics [4]. To meet the rapid development of higher education, we have to focus on the reforms on the integration of modern information technology and the teaching mode of ordinary differential equations.…”

An Advanced Stochastic Numerical Approach for Host-Vector-Predator Nonlinear Model

“…There are various formulation approaches that have been applied to the researcher's community for solving the nonlinear equation systems. Few of them are the Adams numerical scheme [11], Caputo fractional scheme [12], differential transformation method [13], variational iteration technique [14] and a few other methods that have been cited in these References [15][16][17][18][19][20][21][22][23][24].…”
