For the purposes of design of a turbocharger centrifugal compressor, a one-dimensional modelling method has been developed and applied specifically to electrically-assisted turbochargers (EAT). For this purpose, a mix of authoritative loss models was applied to determine the compressor losses. Furthermore, an engine equipped with an electrically-assisted turbocharger was modelled using commercial engine simulation software (GT-Power) to assess the performance of the engine equipped with the designed compressor. A commercial 1.5 L gasoline, in-line, 3-cylinder engine was selected for modeling.

Heat transfer plays an important role in affecting an on-engine turbocharger performance. However, it is normally not taken into account for turbocharged engine simulations.

Since heat transfer situations vary for on-engine turbochargers, the maps have to be shifted and corrected in the 1-D engine simulation, which mass and efficiency

Turbocharging is a way to stay competitive on the market where there are increasing demands on fuel consumption and engine performance. Turbocharging lets the engine work closer to its maximum power and thereby reduces the relative losses due to pumping and friction.

Abstract:
Heat transfer within the turbocharger is an issue in engine simulation based on zero and one-dimensional gas dynamics. Turbocharged engine simulation is often done without taking into account the heat transfer in the turbocharger. In the simulation, using multipliers is the common way of adjusting turbocharger speed and parameters downstream of the compressor and upstream of the turbine. However, they do not represent the physical reality. The multipliers change the maps and need often to be different for different load points. The aim of this paper is to simulate a turbocharged engine and als

Abstract:
Turbocharged Homogeneous Charge Compression Ignition (HCCI) has been modeled and has demonstrated the potential to extend the engine’s upper load limit. A commercially available engine simulation software (GT-Power®) coupled to the University of Michigan HCCI combustion and heat transfer correlations was used to model a single cylinder boosted HCCI engine including a phenomenological turbocharger model. The scope of this study is to explore the upper load limits of boosted HCCI operation and to identify turbocharger requirements for boosting the HCCI. The results of this study are consistent w

Abstract:
Turbochargers are used to either increase engine power output or reduce air pollutants by increasing the trapped air-to-fuel ratio. An increasing need has arisen for the turbocharger compressor to operate at an ever-increasing pressure ratio while maintaining a broad operating range. Unfortunately, the operational physics of a turbocharger limits the operating range as the pressure ratio is increased. This project evaluates the alternatives to increase the engine operating range by using variable vanes on turbocharger compressor.

Abstract:
The natural gas transmission industry has used increased air flow technologies to constrain emissions from reciprocating engines to levels at or below those required by regulations. Typically, the engine is turbocharged or, in the case where a turbocharger already exists on an engine, the turbocharger is �upgraded� to increase the air flow rate through the engine. Oftentimes, the physics of the system and the environmental conditions in which these engine systems operate decrease operating flexibility. This project describes a method to boost the energy to the turbocharger to obtain additional

Abstract:
The natural gas transmission industry has been subject to increasingly stringent emissions regulations over the years, with tougher regulations yet to come. One of the biggest challenges has been to reduce oxides of nitrogen (NOX) while maintaining existing engine reliability and power output. One method of lowering these emissions from reciprocating engines is to use technologies that increase air flow to the engine. Typically, the engine is turbocharged or, in the case where a turbocharger already exists on an engine, the turbocharger is �upgraded� to increase the air flow rate through the e

Abstract:
To develop the requisite air flow rate, the turbocharger must operate at a relatively high efficiency. But as important, the system pressure losses must be minimized to optimize turbocharger operating flexibility so that the turbine can produce sufficient power to operate the turbocharger compressor. The relationship between the various pressures and pressure losses throughout the turbocharged engine system, the turbocharger overall efficiency, ambient conditions, and the required turbine inlet temperature for sustainability is rooted in fundamental thermodynamic principles.

Abstract:
This report outlines the development of the Turbocharger Component Matching System (TuCMS) software package that can be used to inexpensively analyze turbocharger performance, and match turbocharger components to integrate and optimize turbocharger-engine performance. The software system was developed with the intent to reduce the time taken to experimentally match a turbocharger with an engine, a key task to engine reduced engine emissions.

Abstract:
Turbocharger performance, especially on SIP-call engines, remains essentially unmeasured even though tracking information over time would provide critical information to help field engineers lower their engine emissions as well as the cost of operations. In 2006, with the assistance of funding from the Pipeline Research Council International Inc., ScavengeTech LLC developed and field tested a turbocharger monitoring system that consisted of a set of analog sensors to measure key turbocharger performance parameters and hardware to interface the sensor outputs to a computer.

Abstract:
The objective of this project was to either validate the current correlations or develop a new correlation that are used to compare compressor maps. Most compressor maps are presented at standard temperature and pressure. In order to compare data that is not collected at these conditions, correlations are used to relate the data to standard conditions. This project analyzes the validity of currently used correlations and provides improved correlations as needed.
