the intension in this work is to investigate the effect of different bending manifold pipes on engine performance for different engine speed. Power, Torque, and BSFC were calculated and presented to show the effect of varying bending pipes angles on them for all cases considered. A special program used to carry out the calculations. A simulation model for 4-cylinders spark ignition engine with ...

In this paper, a novel reliability prediction technique based on the evidential reasoning (ER) algorithm is developed and applied to forecast reliability in turbocharger engine systems. The focus of this study is to examine the feasibility and validity of the ER algorithm in systems reliability prediction by comparing it with some existing approaches. To determine the parameters of the proposed...

The objective of this paper is a virtual environment that uses CAD models products and their components allows to streamline the design production processes, including assembly processes. creation such can be lengthy but bring significant time financial savings. These savings are based on implementation an already debugged virtually tested solution. article describes process procedure for turbo...

The article presents the acoustic method of marine low-speed engine turbocharger parameter estimation under operating conditions when a prompt assessment instantaneous speed and rotor vibration level is required. lies in analysis signal that generated by compressor with diesel running load. spectral reveals blades generate oscillations are always present overall spectrum regardless its technica...

In turbocharged engines with wastegate the exhaust pressure can change rapidly. A method to estimate the exhaust manifold pressure is presented for diagnosis of wastegate and turbocharger on spark-ignited engines. It does not require any extra sensors in the exhaust system after the calibration. A non-linear model is developed of the exhaust pressure. Estimates of the exhaust manifold pressure ...
