“…At the same time, Naser et al showed in the 2016 study that as the engine speed increases, the turbocharger shaft speed increases. For this reason, a linear increase in volumetric efficiency was observed in this study as the engine speed increased [4]. As a result of these, a decrease in the air tank filling time given in "minutes:seconds" was observed in Figure 6 due to the increase in the speed and the flow rate of the air pumped in the compressor fed by turbocharged compared to the naturally aspirated compressor.…”

“…Naser et al in 2016 showed that in the study they conducted on a turbocharged Cummins diesel engine with cooling, turbocharger turbine speed increased almost parallel to engine speed from 1200 to 1800 rpm [4]. The turbine shaft speed is approximately 30 times faster than the engine speed of a vehicle [13].…”

“…Simulation results in the range of 1200 rpm and 1800 rpm engine speeds for the temperature and pressure values, flow rate and heat transfer rate in the cylinder and manifolds depending on the crank angle. As a result, it has been argued that the parameters such as injection angle, intercooler efficiency, turbocharger characteristics, intake and exhaust manifold volumes can be observed during the diagnostic process [4].…”

Reciprocating compressors, which come from the past to the present and whose development is parallel to internal combustion engine technolo-gies, find themselves a large share in this field in line with the innovative studies on it. The stored compressed air demanded in the heavy vehicle segment, where almost all diesel engines are used, is serviced for two main tasks such as brake and suspension system. Therefore, the engine to be used during the compressor selection; efficiency, performance and service maintenance period are very important while meeting the de-mands and what applications are used such as long-distance vehicle, construction site vehicle, transport vehicle, garbage truck, coach.In this paper, experimental studies were carried out on a Scania brand diesel vehicle by feeding the air brake compressor from the engine tur-bocharger intercooler with an improved interconnection and convention-al atmospheric feeding. Temperature and pressure values obtained via sensors from the data collection system, performance information ob-tained from the vehicle CAN module and exhaust emission measurement results measured by opacimeter for both cases are presented.

“…However, engine system modification requires modifications to the engine architecture. In a turbocharged engine, high gas pressure can result in an excessively hot intake charge that significantly reduces the performance gains from turbochargers 13 . Therefore, turbocharged engines always need a cooling system to drop the air temperature of the turbocharger compressor outlet.…”

It is interesting to improve engine system performance with turbocharger technologies. In this study, a systematic simulation for engine and turbocharger matching to provide full utilization of the turbocharger potential and improve the engine performance without sacrificing the emission is developed. A velocity ratio concept was proposed to count the turbocharger performance impacts due to the diameter ratio of compressor and turbine wheels. A design of experiments was used to optimize the turbocharger and engine performance for different turbocharger factors. A better‐matched turbocharger was obtained. A multidisciplinary optimization method was used to design a mixed flow turbine wheel to reduce the turbine velocity ratio at peak efficiency and increase the overall turbocharger efficiency. Results showed that about 0.4% torque improvements and 1.2% reductions in the engine brake‐specific fuel consumption were obtained without making any other changes to the engine. This study demonstrated that systematic simulations for engine systems and considering turbocharger wheel diameter ratio effects could further improve the turbocharged engine system matching and the engine performance.

“…Charge air cooling-(CAC) of engine inlet air temperature reduction, influence the air density and flow pressure property [10][11][12]. In a compressive intake air charge using a turbocharger and supercharger, the compression effect led to an increase in air temperature and pressure [13,14]. The rise in air charge temperature is not desirable for combustion, as the air density contains fewer oxygen molecules [15,16], leading to incomplete combustion and causing the engine cylinder temperature to rise, which leads to pre-detonation of the combustion [17].…”

Nowadays, the concern of vehicle manufacturers towards improving engine performance, reducing fuel consumption and exhaust emissions that can cause the pollution of the atmosphere, concerns of strict emission pollution control regulations. Intercooler heat exchanger devices are used for engine charge air temperature improving for engine performance and emissions reduction. This paper introduces a new add-on technology of intercooler heat exchanger- (IHE) developed for utilizing in intake charge air density enhancement in engine combustion for better performance. Presenting a challenge in contributing a framework process for geometry designing development procedure for accurate and reliable scale design size of an air-vapour gas shell-and-tube IHE type, used refrigerant coolant medium. The process presents effective IHE in design time consumption, accurate in scale with higher performance and reliability operation in all environment weather due to reversibility system. A selected design geometry of 60 bunches of tubes with 7.53 mm inner diameter and 150 mm long placed. Effectiveness and design parameter geometry calculation are conditions of the IHE dependent relations of the shell size to tube length in condition of engine space availability control. Pressure drop and cooling capacity of IHE configuration design are proportional to the availability of design space or pressure drop control by the engine. Numerical and simulation results expressed a significant ability of IHE of 2–13 kW cooling load and process applicability for qualified design geometry configuration for selected IHE type. The developments present significant geometry flexibility design with the ability of cooling load or heating effect if reversible system, which offered multipurpose use in widely all vehicle types.
