چکیده

Turbocharging is one of the foremost ways engine downsizing and represents leading technology for reducing CO 2 emission standards in gasoline application. Turbocharger turbine always faces high unsteadiness flow coming from reciprocating internal combustion engines. Besides, increasing levels include rising degrees pulse charging. Utilization energy exhaust interferences between cylinders using double-entry turbines a vital element solving low-end-torque targets improving rated power highly boosted four-cylinder The present paper describes model turbines. model’ aim to accommodate an efficient boundary condition turbocharged models with zero one-dimensional gas dynamic codes. based on simple procedure testing systematizing performance maps these different admission conditions. However, described capable extrapolating operating conditions that differ those included because turbocharger usually works instantaneously away narrow range data are measured stand. has been implemented code used calculate unsteady engine. results obtained whole simulation show can produce all full load variables such as air mass brake torque reasonable degree agreement experimental test bench.

Performance analysis a gas turbine cycle equipped with a double acting type stirling engine in a power generating unit

The aim of this study is to investigate the performance of a gas turbine cycle equipped with a Stirling engine from the thermodynamic point of view. In this system, part of the heat loss from the gas turbine is transmitted to a Stirling engine to generate more power. In the proposed system analysis, the governing equations of the hybrid cycle are modeled in MATLAB software and Schmidt and ideal...

Investigation of Dual Fuel Diesel Engine With Particular Reference to Engine Cycle Model

In order to use gaseous fuels in Diesel Engines, Dual-Fuel Diesel Engine (D. F. D. E) the pilot injection approach is chosen. To predict its performance, an engine cycle model, based on limited-pressure Diesel cycle, is constructed. The model predicts D. F. D. E performance with LPG, and CNG gases. Comparing with pure Diesel engine, by increasing gas proportion in dual-fuel, indicated power and...
