Aero-engine real-time models are widely used in control system design, integration, and testing. They can be as the basis for model-based engine intelligent controls health management, which is critical to improve safety, reliability, economy, other performance indicators. This article provides an up-to-date review on aero-engine modeling methods, model adaptation techniques, applications last ...

The one dimension computational model of a sequential injection engine, which runs on compressed natural gas (CNG) with spark ignition, is developed for this study, to simulate the performance of gas flow pressure profile, under various speed conditions. The computational model is used to simulate and study of the steady state and transient processes of the intake manifold. The sequential injec...

Research in this paper is concerned on bay cooling of the new type turboprop engine. The considered engine integration substantially increases temperature inside front nacelle compartment. In order to achieve optimal conditions for parts all operating regimes and engine/nacelle regime after aircraft landing at heat soak-back, a system proposed. Proposed consists standard NACA inlets nacelle, tw...

Modern automotive engines are controlled by the electronic control unit (ECU). The electronically-controlled automotive engine power & torque are significantly affected with effective tune-up of ECU control parameters. Current practice of ECU tune-up relies on the experience of the automotive engineer. The engine tine-up is usually done by trial-and-error method, and then the vehicle engine is ...

in this study the performance and emissions characteristics of a heavy-duty, direct injection, compression ignition (ci) engine which is specialized in agriculture, have been investigated experimentally. for this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (bsfc), peak pressure (pp), nitrogen oxides (nox), carbon dioxide (co2), carbon mon...

nowadays, due to the increasing power of diesel engines, especially heavy duty diesel engines, and increasing gas pressure inside the combustion chamber, the forces acting on the engine bearings have dramatically raised. on the other hand, becaus eof the competition in the market, it is necessary to increase the engine bearing life and reduce its failure as much as possible. the engine bearings...

We have designed a fully-integrated analog CMOS cognitive image sensor based on two-layer artificial neural network and targeted to low-resolution classification. used single poly 180 nm process technology, which includes modules for realizing the building blocks of sensor. Our design all sub-circuits required perform sensing task, from output classification decision. The weights are stored in ...

in this study, the mf285 tractor engine vibrations resulting from the use of different combinations of biodiesel, bioethanol and diesel as fuel were studied. engine vibrations in three directions and three engine speeds: 1000, 1600 rpm 2000 and ten fuel level was measured. to investigate the influence of measured parameters on engine vibration of factorial design in a randomized complete block ...
