“…The main characteristic of the engine are given in Table1. The validation of engine 1D model is mentioned by Vichi et al [35] and Romani et al [36]. This engine uses a turbocharger model MGT 1238 composed of a single-entry radial turbine and a small centrifuge compressor, which the main characteristic are given in Table2 and Tab 3, respectively.…”

“…16(a)). The inlet total pressure signal is obtained from the WAVE model of a mono-cylinder of 0.5 liter developed by Vichi et al [35] and Romani et al [36].For one engine cycle the inlet total pressure is subdivided into nine intervals to well cover these variations, which helped to better follow the response of the turbine and investigate the effect of each wave on the hysteresis-loop. The first interval represents the time of the constant pressure corresponds to the period when the exhaust valve is closed, while the second and third interval represent successively the rise time and descent time of the highest pressure wave whereas the remaining intervals represent the complete successive waves.…”

“…For the mono-cylinder spark ignition engine matched with the single-entry radial turbocharger, the total moment of inertia of the turbocharger equals 4.9 10 -6 kg.m 2 and the intercooler efficiency 𝜀=0.92 taken at full-load for divers engine speeds [35,36]. The same procedure as above used the maps of the single-entry radial turbine and the centrifugal compressor of the turbocharger MGT 1238.The Turbo Compressor Map (TCMAP) procedure provides the centrifugal compressor and turbine maps over the wide range of operating points and this is justified by the fact that the experimental data are not well suited for use in simulations for diverse reasons.…”

This paper investigates numerically the effects of pulsating exhaust gases on the operations of radial inflow turbines and their matching with internal combustion engines at full-load conditions. Both single- and twin-entry radial turbines are considered and the transient behaviors are analyzed by combining the CFD and analytical models. As results, the unsteady performances are shown to deviate noticeably from the steady state due to high levels of unsteadiness of the inlet conditions. A typical hysteresis-loop relating the effect of gas filling-emptying inside the volute is well depicted. Unsteady performance of the twin-entry radial turbine depicts that the of hysteresis-loop is wide due to large volute volume whereas the hysteresis-loop of single-entry turbine seems reducingas the amplitude of pressure pulse reduces. For the compressor side of the twin-entry radial turbine, and depending on the engine speed, the average values of unsteady performances exhibit deviations up to 9% in pressure ratio and 7.8% in airflow swallowing capacity, in contrast to the single-entry radial turbine these deviations are lesser about 4 and 4.9%, respectively. These differences could be related to the two sides of volute which are source of hysteresis and flow interaction.

“…To tackle these issues, a 3D modeling and internal flow distribution are performed using SolidWorks and CFD analysis, respectively. Vichi et al [9] designed the engine intake system of the Firenze Race Team vehicle with the aim of providing an optimum performance in terms of both the maximum power and the drivability. For this purpose, they firstly optimized the plenum volume in order to limit the influence of the restrictor.…”

This paper involves the design and construction of the intake manifold system of the FSAE car including the air shroud, air filter, throttle body, restrictor plenum, fuel injectors, fuel rail and runners. To ensure the quality, the proposed system is designed based on the FSAE rules. The design process of the intake manifold system will consist of the usual engineering processes including computer modelling, Finite Element Analysis and finally Computational Fluid Dynamics testing in order to determine the validity of the model and to tune the design in order to obtain the optimum performance out of the intake manifold system as a whole.

“…One of the improvements in car performance to get maximum results at dynamic events is to modify the air intake. The basic function of an air intake system is to provide the throttle body with air where it is then mixed with the fuel and then sent to combustion chamber [2][3][4][5] . Air intake is important to determine the power and torque that will be generated by the engine.…”

One of the rules of Student Formula SAE is air intake must have a restrictor located after the throttle body with 20 mm maximum diameter. It causes engine power and torque decreased. To increase engine performance, modify the bellmouth radius and venturi restrictor length are some of options. The authors analyzed the effect of them on power and torque produced by KTM 450 SX-F engine of Bimasakti UGM's 9th generation car (BM-9). The authors made 9 design variations then simulated by Ricardo Wave 2016.1 and Ansys Fluent 18.1 software. The result is, greater the bellmouth radius and venturi restrictor length produced higher value of peak power and peak torque.
