to calculate the data of the main pollutant emission from diesel engine is simulated by the pollution emission chart which is proved that satisfactory results can be available in medium and small load.The formula can be a concise way to calculate main pollutant emissions from diesel engine.关键...
Neural network surrogates for empirical formulae In the mean value engine model proposed in1, empirical formulae, e.g., polynomial functions, are employed for the volumetric efficiency (\(\eta _{vol}\)), effective area ratio function for EGR valve (\(f_{egr}\)), turbine mechanical efficie...
By adopting the diesel engine oil formula provided by the invention, the wear resistance of equipment is greatly improved, the thermal stability and the oxidation resistance of an oil product are enhanced, the service life is prolonged, and the effects of high efficiency, oil saving, energy ...

2 DIESEL FUEL is known for its high energy density and efficiency, making it a popular choice for transportation and industrial applications. It is characterized by its low volatility and high flash point, which contribute to its safety and stability during storage and use. This fuel is widely ...
Gene expression programming and its values exactly predict output results and present precise formula. Moreover, the sensitivity analysis was performed to recognize the effectiveness of the factors for reducing NOx and increasing mechanical efficiency. In the sensitivity analysis, the methods such as ...
Further significant reductions in engine out NOx emissions could be achieved by increasing the EGR rate. A moderate EGR rate was used in this case, however, to avoid major changes in the fuel efficiency, ηf,ig. Accordingly, ηf,ig was unchanged from the case without EGR for Diesel and ...
Perkins announced the development of the Perkins 2600 Series, a new 13-liter diesel engine platform designed to achieve best-in-class power density, torque and fuel efficiency for heavy duty off-highway applications. Targeting applications in agriculture, construction, and numerous other sectors, the...
This cooling technique, which is common in Formula 1, has been combined with a double water jacket design for the cylinder head. Transverse water flow, which is used in F1 to maximise cooling efficiency and minimise downforce losses, enables a smaller and...
Nearly all mine workers are exposed to aerosols—both mechanically generated and from combustion[1–4].Dieselengine exhaustis a primary source of submicron (particles with diameter <1μm) mine aerosols[5]. Diesel is an efficientfossil fueland the energy efficiency ofdieselmakes it an attractive ...
