This paper was to analyze the air intake system of turbo charged diesel engine. This was done by measuring the pressure drop across the air filter in the air intake system. Both static and dynamic measurements were conducted with the help of pressure measuring devices such as U - tube manometer and vacuum gauge. The point of measurement was at the tapping provided for restriction placed in between air filter and turbocharger compressor. Vehicles from various categories such as passenger vehicles, light commercial vehicles (LCV) and heavy commercial vehicles (HCV) were taken up and analyzed.

The impact of different structure parameters to the flow field of the intake system is analyzed in the paper, the one-dimensional porous jump model is applied to model the filter paper. Meanwhile, silencing component is added to the intake system to degrade the noise peak value and improve silencing performance at low-frequency. The comparison of the simulation and testing results shows good agreement. It is proved that the acoustic performance of the intake system has been greatly improved after adding the silencing component.
This article has proposed a new method for designing and studying engine intake system based on the technology of CAD/CAE/CFD integration. Firstly, according to the similarity principle and pressure wave theory, the structure parameters of target engine intake system were defined referencing the similar engine. Then, the intake system parameters were input into GT-power, and the intake system performance was simulated and optimized. Next, the 3-D structure model was designed based on CAD software and optimized values. After that, the key parts of intake system were analyzed and optimized by using CAE and CFD. As a result, a new intake system has been designed. The whole processes of designing and studying intake system included parameters define, performance optimization, structure design, flow calculation, noise and vibration analysis, were coupled together. And the feasibility and effectiveness of the idea was validated through practical example. The study results have provided guidance for designing intake system of engine.
The paper studied on a 125cc single-cylinder gasoline engine. Within the range of engine economical rotational speed, optimized structure of intake pipe can arouse airflow of inertial and resonant effect. The theoretical model analysis and computer simulation provides directional guidance of improving intake system, which may reduce test cost and shorten the redesign cycle. Through the experiment of speed characteristic on dynamometer bench, test data of original and improved intake pipes were compared. Both theoretical models and experimental results show that the effective use of intake pulsation can improve the engine power performance and fuel economy.
Recently, more attention was put on the noise control of automotive. To reduce the noise of intake system of some kind of automotive, a model of automotive intake system was found based on transfer matrix method and black box experimental method. Then to fulfill the requirement of design and realize better anechoic effect, single objective optimization and multi-objective problem was formulated. To get the optimal performance and the optimal structure parameters, the problems were solved by genetic algorithm (GA) and NSGAII through Matlab platform, and optimal analysis was carried out to get the optimal parameters under different requirements and soft constraints. The results of our work have the guiding sense to the reality production.
At the design beginning of a certain type of passenger car, the noise spectrum of the air intake system is analyzed. Firstly, the structure model and acoustic model are established by GEM3D, and then GT-Power was used to analyze the noise of the system and simulate the full load condition of the engine. The sound pressure levels of the third, sixth, ninth, and twelfth order nozzle noise at 1000-6000r/min were respectively calculated and optimized. Comparing the sound pressure levels, the results show that the each order and the total sound pressure levels of the intake system do not exceed the target curve to meet the noise reduction requirements.
Accurately estimating or measuring intake manifold absolute pressure plays an important role in automobile engine control. In order to achieve the real-time estimation of the absolute pressure, the high accuracy and high speed processing ability is commonly required for the automobile engine control system. However, the conventional numerical methods cannot satisfy the requirement of the strict time needed by high speed automobile engine. Therefore, in this paper, an analog LSI method is proposed to estimate this pressure in real time. Furthermore, a novel behavioral macromodel is given for further analog LSI design. Compared with conventional numerical method, the proposed method is highly advantageous in speed to simulate the automobile engine intake system
The accurate air-fuel ratio control of electronic fuel injection system is based on exact measurement of intake flowrate, which is the important measure of reducing exhaust emission and improving fuel economy. Taking the nonlinear character of intake system into account, an intake dynamic model is studied based on the mean value engine model, and the relation between manifold pressure and intake system parameters is given. According to the application trait of Kalman filter, an estimated method of engine intake flowrate is put forward based on extended Kalman filter (EKF). The iterative equation is obtained by simple linearization of nonlinear system. Intake pressures with different transient operation condition are computed. The study shows that the calculated value and the measurement value possess the characteristics of good tracing with little deviation. The predictive effect is satisfactory
In order to reduce intake noise without affecting the intake performance of motorcycle engine, computer simulation was used to optimize the design of intake system. Firstly, the GT-power simulation model of original engine was built and calibrated based on engine test data. Next, the performances of original engine, such as volumetric efficiency and intake noise, were obtained by simulation calculation. Then, based on Helmholtz resonance principle, the intake system was optimized aimed at the noise peak frequencies. The intake noise and intake performance of optimized intake system were obtained through re-simulation. Compared to the results of original engine, the optimized intake system can greatly reduce intake noise almost without decreasing intake volumetric efficiency. The study results have provided a good method for optimizing intake system.
In order to apply an engine intake air system model to engine control, it is necessary to calculate the intake air system model quickly and accurately under constraints of computational performance. Therefore, a study has been made on a method for calculating the intake air system model implemented by an analog LSI at short times. However, the problem is to include the model error in the intake air system model based on the analog LSI of present state. This paper reports a compensation of the intake air system model with error by Extended Kalman Filter (EKF).A basic model that reproduces model errors of analog LSI model is built, and a compensator based on EKF is designed. As a result, it is confirmed that the compensator reduces the model errors by half. Moreover, this paper reports the numeric solution in order to reduce the hunting phenomenon of the engine intake air system model.
