Natural gas, which is also referred to as eco-friendly fuel, being seen a potential solution challenge the decline of crude oil resources and deteriorating air quality in urban areas. This fuel has been verified emit less CO, HC, PM compared other fuels. A approach reducing NOx soot emissions while achieving low consumption temperature combustion process. In this study, internal engines were si...

Exhaust Gas Recirculation (EGR) concept is the most simple and Abstract more economical method for NO pollutant reduction in spark ignition engines. However, when the higher amount of the EGR gas enters into the engine, the power, torque and fuel economy of the engine decrease. One effective solution for reduction of undesirable effect of this method is to use cooled EGR, that results in more r...

The constant development of civilization increases environmental pollution as a result industrial activity and transport. Consequently, human in this area is restricted by regulations governing the permissible emission harmful substance components into environment. These include substances emitted combustion engines, use which remains high many industries. research being conducted to reduce emi...

the request for natural gas attention to its adaption with environment and less pollution than the other fossil fuels has the highest growth in last decades. in result this energy has high geopolitical importance. iran with has about 2.18 percent of total world reserves, the largest in the world. but couldn't played important role in the natural gas geopolitics and even it hasn't in b...

Combined power generation or cogeneration is a highly effective technology that produces heat and electricity in one device more efficiently than separate production. Overall effectiveness is growing by use of combined technologies of energy extraction, taking heat from flue gases and coolants of machines. Another problem is the dependence of such devices on fossil fuels as fuel. For the combus...

Aircraft engine performance trend monitoring and gas path fault diagnostics are closely related technologies that assist operators in managing the health of their gas turbine engine assets. Trend monitoring is the process of monitoring the gradual performance change that an aircraft engine will naturally incur over time due to turbomachinery deterioration, while gas path diagnostics is the proc...
