Introduce electronic control exhaust gas recirculation EGR system in the passenger cars and light duty vehicles was made because of fuel direct injectionengines. In this engines temperature combustion process is a higher then other type engine and in this connections NO, emissions were higher to. Simultaneously was appearing problems to electronic exhaust gas recirculation control in connection...

The exhaust gases of gas turbine power plant carry a significant amount of thermal energy that is usually expelled to the atmosphere this causes a reduction in net work and efficiency of gas turbine. On the other hand, the generated power and efficiency of gas turbine plants depend largely on the temperature of the inlet air, So that they both increase as the inlet air temperature decreases. Th...

Combined Cycle Gas Turbine (CCGT) integrates two cyclesBrayton cycle (Gas Turbine) and Rankine cycle (Steam Turbine) with the objective of increasing overall plant efficiency. In modern gas turbine the temperature of the exhaust gases is in the range of 500 oC to 550 oC. Modern steam power plants have steam temperature in the range of 500 oC to 630 oC. Hence gas turbine exhaust can be utilized ...

In a turbocharged engine, preserving the maximum amount of exhaust pulse energy for turbine operation will result in improved low end torque and engine transient response. However, the exhaust flow entering the turbine is highly unsteady, and the presence of the turbine as a restriction in the exhaust flow results in a higher pressure at the cylinder exhaust ports and consequently poor scavengi...

In this paper, the influence of the gas exchange process on the diesel engine thermal overload is provided. Main components involved in the gas exchange process are discussed. The ambient conditions, the turbocharger performance, and the valve timing that affect the gas exchange process have been investigated. Experiments were conducted to simulate ambient conditions at different geographical l...

European regulations regarding exhaust gas emissions have constantly become more restricted in the last decades. Components of the exhaust gas after-treatment system and ECU strategies have become correspondingly more complicated in order to fulfil the prescribed limits. This paper describes how a real time HIL engine simulator can be used to test EOBD ECU strategies, in order to reduce the amo...

Motor vehicles are major sources of gas-phase organic carbon, which includes volatile organic compounds (VOCs) and other compounds with lower vapor pressures. These emissions react in the atmosphere, leading to the formation of ozone and secondary organic aerosol (SOA). With more chemical detail than previous studies, we report emission factors for over 230 compounds from gasoline and diesel ve...

introduction: during the thirty years ago noise pollution increased quickly in the urbane communities that motorcycles are chief sources of noise. the objective of this study is reduction of noise emitted from motorcycle exhaust, applying engineering design. materials and methods: in this pre-experimental study, current condition of noise emitted from motorcycle exhaust and physical parameters ...

Internal combustion engines rejects 30-40% of the energy supplied by fuel to the environment through exhaust gas. thus, there is a possibility for further significant improvement of efficiency with the utilization of exhaust gas energy and its conversion to mechanical energy or electrical energy. The Thermo-Electric Generator (TEG) will be located in the exhaust system and will make use of an e...
