“…Most researchers focus on studying the intake and exhaust manifold. The intake and exhaust manifolds are usually bend pipes, and researchers have studied the effects of changing the structure and layout of the manifold on gas flow uniformity and cylinder volume efficiency to explore whether engine performance is improved [7][8][9][10][11][12][13][14][15]. Silva et al, showed in their latest research that the engine has higher volume efficiency at high speeds when the length of the intake manifold flow path is shorter [16].…”

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.

In the work, the suitable volumetric efficiency is very important for the gasoline engine to achieve the aim of energy-saving and emission reduction. Thus, the intake system characteristics, such as intake manifold length, diameter, volumetric efficiency, and valve phase, should be investigated in detail. In order to investigate the performance optimization of the engine intake system, an optimization model of the engine intake system is developed by the GT-Power coupled with Matlab-Simulink and validated by the experimental results under the different conditions at full load. The engine power-, torque-, and brake-specific fuel consumption are defined as the result variables of the optimization model, and the length and diameter of the intake manifold are defined as the independent variables of the model. The results show that the length of intake manifold has little influence on the engine power and BSFC, and the length of intake manifold has a great impact on the performance index at high speed. In addition, the engine volumetric efficiency is the highest when the length of intake manifold is in the range of 240 and 250 mm. The engine BSFC improved by variable valve timing is significant compared with the original result. Finally, the improvement suggestions for the performance enhancement of the gasoline engine are proposed.

It is a relevant objective in thermal physics and piston engine construction to develop technical solutions for controlling the gas dynamics and heat exchange of gas flows in the intake system of turbocharged engines in order to improve performance. The article presents other authors’ data on the improvement of processes in the gas exchange systems of piston engines. It also provides a description of experimental set-ups, instruments, measurement tools and research methods for establishing the thermal-mechanical characteristics of pulsating flows in the intake system of a turbocharged engine. The instantaneous values of the gas flow rate and the local heat transfer coefficient were determined using the measured results by applying a constant temperature hot-wire anemometer (H-WA). The article describes technical solutions for influencing the gas dynamics and heat exchange of gas flows by stabilising and turbulising the flow. The regularities of changes in the instantaneous values of the flow velocity, pressure and the local heat transfer coefficient in time for a pulsating gas flow with different intake system configurations are obtained. It is shown that the installation of a levelling grid in the compressor outlet channel leads to the stabilisation of the flow and the suppression of heat transfer in the engine intake system by an average of 15% compared to the base system. It was found that the presence of a channel with grooves in the intake system leads to flow turbulisation and the intensification of heat transfer in the intake system by an average of 25%.
