“…Capon et. al [2] tested the Honda engine by changing the dimensions of intake manifold of turbo charger. If the intake turbo charger is altered by dimensions 15.1x6x2.25 inches, this core should be large enough to provide good heat transfer while limiting flow losses through the intercooler, and the air/air core added less weight to the chassis than the alternative air/water core.…”

Turbochargers are an integral part of today’s modern diesel engines and are a major reason that they are able to produce more power. Unlike a super charger that is driven via a belt from the engine, a turbo takes the exhaust that the engine is producing and puts it to good use. As Turbochargers are driven by exhaust, heat is an unwelcome by product and something that wasn’t really taken into account in automobiles. Then those intercoolers started to come into play in turbocharged automobiles. The forced air produced by the turbocharger is routed through the intercooler where its temperature is reduced before reaching the engine. The use of intercoolers has made turbocharged vehicles far more reliable and, in the case of today’s heavy duty diesel trucks, is a very important component. The inlet air of an IC engine from turbocharger temperature is very much high (due to compression) means oxygen content is very much less. And also air with high temperature causes pre-ignition and detonation. So fuel combustion does not take place properly. Inter Cooling of inlet air is very much essential according to performance point of view. Turbo intercoolers are used for cooling the inlet air of an IC engine from turbo chargers. Moreover cooling of air makes it denser and contributes for better combustion and more power they are mounted close to the radiators for achieving lower air temperature. This arrangement affects the performance of both. So in this project an attempt will be made to increase the efficiency of the turbo intercooler arrangement through design modification and repositioning of intercooler by taking the TATA MARCOPOLO-Star Bus 909 as a reference.

Intake boosting is an important feature of modern engines, directly benefiting the specific power output and indirectly responsible for improvements in efficiency. It is also essential to compensate for the loss of power brought about by combustion systems that are designed to limit engine emissions. Intake boosting is done by superchargers and turbochargers. By far, the most common method of boosting is by turbocharging, which is the main focus of this chapter, but supercharging and charge air cooling also feature. The principal components of the turbocharger are the compressor and turbine, and their performance parameters and maps are described. The operational characteristics of a turbocharged engine are largely determined by the match between the engine and the turbocharger. The performance characteristics of each component and the ways in which they interact in automotive engines are discussed in detail. From this, the need for boost control devices such as wastegates and variable geometry turbines becomes apparent. Other intake boosting systems, including series turbochargers, turbocompounding, electric assist, and pressure wave superchargers, are also described.

Downsizing and turbocharging are today considered an effective way to reduce CO2 emissions in automotive gasoline engines.\ud To this aim, a deep knowledge of turbocharger behavior could be a key solution to improve the engine-turbocharger matching\ud calculation. The influence of the intake system geometry on the surge line position is an important aspect to guide the project of\ud the intake manifold, enlarging the compressor stable zone. This aspect has a considerable impact on engine performance,\ud especially during transient operation. A wide experimental investigation was carried out at the turbocharger test facility of the\ud University of Genoa on a small turbocharger compressor. Compressor characteristic curves measured considering an automotive\ud intake circuit are compared with standard maps provided by turbocharger’s manufacturer. This information allows the\ud optimization of 1D model implementing more realistic maps of compressor. The influence of three different layouts has been\ud investigated varying overall circuit volume and length, keeping values in a range compatible with passenger cars packaging\ud constraints. In the paper, the main results of the experimental campaign are presented taking into account the influence of\ud geometry variations on compressor map and surge line position
