Throttle Valve

Automotive manufacturers nowadays are constantly working on improving their internal combustion engines’ performance by reducing the fuel consumption and emissions, without compromising the power generated. Manufacturers are therefore relying on virtual engine models that can be run on simulation software in order to reduce the amount of time and costs needed, in comparison with experiments done on engine test benches. One important element of the intake system of an internal combustion engine is the throttle valve, which defines the amount of air reaching the plenum before being drawn into the cylinders. This article discusses a widely used model for the estimation of air flow rate through the throttle valve in an internal combustion engine simulation. Experiments have been conducted on an isolated throttle valve test bench in order to understand the influence of different factors on the model’s discharge coefficient. These experiments showed that the discharge coefficient varies with the pressure ratio across the throttle valve and with its angle. Furthermore, for each angle, this variation can be approximated with a linear model composed of two parameters: the slope and the Y-Intercept. These parameters are calibrated for different throttle valve angles. This calibration can be done using automotive manufacturers’ standard engine test fields that are often available. This model is then introduced into an engine simulation model, and the results are compared to the experimental data of a turbocharged engine test bench for validation. They are also compared with a standard discharge coefficient model that varies only with the throttle valve angle. The results show that the new model for the discharge coefficient reduces mass flow estimation errors and allows expanding the applications of the throttle valve isentropic nozzle model.

Today, stands for running in and testing internal combustion engines are actively used both at car service enterprises and in the educational process of specialized specialties of educational institutions. The article analyzes the stand KI-1363-V, installed on the basis of the department of technical service and repair of machines of the Federal State Budgetary Educational Institution of Higher Education of the Perm State Technical University, proposed and implemented measures for its modernization. In addition, a review of analogues on the market was carried out, as a result of which it was established that the purchase of a ready-made complex for testing internal combustion engines is economically unjustified. In the course of the work, a hardware and software complex (HSC) was developed and implemented, which allows automating the processes of taking performance characteristics from the engine under test and reducing the measurement error in order to increase the efficiency of using the test bench. In addition, the article describes the work carried out on the modernization of the test engine, implemented an engine management system with distributed fuel injection and electronic control. The electronic control unit for the engine and the stand and the specialized software "APK of the KI-1363-V stand" have been developed, which, in conjunction with the EFI Analytics TunerStudio software product, allows to implement a wide range of research and laboratory work related to tuning and characterizing the tested internal combustion engine...

In this paper, we submit an advanced solution for the optimization of the supercharging process in the engines that are experimentally researched on the test bench. This solution may be applied only to the engines set on the test bench, whose energy, economic or ecological performances require an impetus by the optimization of the supercharging process. Cutting-edge automatic equipment for the achievement of the supercharging process should be used, with a view to studying and improving the behaviour of the experimentally researched engines, depending on the intensity of the supercharging process. In this way, the parameters to be fulfilled by the supercharging aggregate, which will equip the internal combustion engine, during its exploitation, will be known.
