In order to reduce the temperature in marine engine cabin, improve working environment of staff and meet economy emission requirements, cooling system was experimentally investigated present study. this regard, water air-cooling schemes were studied main indicators including torque, smoke-emission, exhaust analyzed. The obtained results indicate that highest torque can be from turbine case pipe...
To study the typical failure mechanism (rotor unbalance, rotor friction, and crack) vibration characteristics of turbocharger system, a system dynamics simulation model was established by an improved four-node aggregate parameter method. The geometric physical under three states its operation were analyzed. Thus, established. On this basis, output signal extracted using Hu invariant moment feat...
The gas flow estimation is crucial for the proper operation and monitoring of turbocharged (TC) engines with a torque structured engine control unit (ECU). This paper presents mean value models developed for modeling gas flow over the compressor, the turbine and the wastegate (WG) in a TC gasoline engine not equipped with a hot film air-mass flow meter (HFM). The turbine flow ...
Increasing the power (torque) of nowadays engines, along with reduction of fuel consumption and dimensions of them, cause to the use of turbocharged systems. Since turbo chargers are exposed to the exhaust hot gases and have a high operating speed, it is necessary to utilize high technology design and special materials with high cost. The temperature of the exhaust system with gasoline fuel som...
