“…Because the air content was added for mixing with syngas improving the non-premixed combustion phase, it was more complete combustion and the main fuel injection was dropped. Then, the total energy consumption was decreased at same power [15][16][17][18][19][20][21]. Importantly, the adding EGR between 0.36 and 0.84 lpm could decrease BSEC, relieved up to 5.41% from using DF mode D. These results were assumed by the air content used in diffusive combustion zone was sufficient for the more syngas-EGR combustion, and then the main regular diesel injection was less.…”

“…The reduction of NO and the addition of CO were shown. CO2 and black smoke were different, when compared with the modes of only diesel and dual-fuel diesel combined with syngas [14][15][16][17][18][19][20]. Although oxygenate fuels could control some exhaust emissions, the increase of syngas by restricting air led to the fuel-rich combustion.…”

Syngas produced from biomass fuels is studied for renewable energy in combustion engines. Syngas used in dual fuel modes can reduce diesel consumption in diesel engines, but exhaust products are increased. Exhaust gas recirculation (EGR) can increase fuel efficiency and decrease exhaust emissions. Therefore, the research aims to study the performance and emission of a diesel-engine generator at 3,000 rpm and various loads, fueled with dual fuel modes by adding syngas, air, and EGR. Syngas was generated from wood pellet by a downdraft gasifier. Flow rates of syngas and air were added at 93 lpm and 86 lpm, respectively. EGR was expanded from 0.36 to 1.92 lpm. The best engine performance in dual fuel modes was found at 3.82 kW. The increase of syngas, air, and EGR flow rates led to the changes of engine performance and exhaust products. Regular diesel combined with syngas-air-EGR blend by increasing syngas, air, and EGR at 93 lpm, 86 lpm, and 0.84 lpm led to the addition of engine performance and the reduction of exhaust emissions. Outstandingly, carbon dioxide, carbon monoxide, nitric oxides, and particulate matter were decreased by 2.98%, 10.08%, 12.64%, and 2.60%, respectively. The regular diesel saving was raised by 43.33% compared with the mode of only regular diesel.

“…Immediately after that, the actuator is subdivided into two parts: electro-hydraulic servo valve and hydraulic cylinder, and analyzed in detail for its working principle and structural classification respectively [1][2][3] . The control scheme of typical electro-hydraulic servo-valve-driven hydraulic cylinder, due to its advantages of fast dynamic response, high output power, high control accuracy, good linearity, small dead zone, high sensitivity, etc., has been widely used as the driving device and actuating part of the actuator of the aero-engine for controlling the fan guide vane of the engine, the guide vane of the pressurizer, the area of the nozzle as well as the angle of the vector nozzle, etc [4][5]. In addition, computer simulation is used to replace the physical control system.…”

The actuator is an essential part of the aero-engine control system, and its performance directly determines the efficiency of the whole system. The mathematical model of the aero-engine actuators, including electro-hydraulic servo valves, hydraulic cylinders, and actuators, is modeled and the time-frequency characteristics are analyzed using the Simulink module. Then, the system response is simulated and its time-frequency characteristics are analyzed. The simulation results show that the simulation error of the established actuator model is within the allowable range. The displacement response and the servo valve flow response fluctuate slightly near the steady state value, and the error value is only 0.857% at the maximum fluctuation value, and the system still works normally when a dynamic load is added to the system.
