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...
A larger value for the EER means that the combustion of during the closed cycle occurs during its thermodynamically favorable position. A lower value explains a lower closed cycle efficiency. The COVIMEP quantifies the variability of the indicated work per cycle in terms of the standard deviation...
11.1Diesel use in mining 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 ofdies...
Nano-graphene lubricating oil with appropriate concentration shows excellent performance in reducing friction and wear under different working conditions of diesel engines, and has been widely concerned. Lubricating oil has a significant impact on partic
There are two types of diesel engine, the two-stroke engine and the four-stroke engine. As the names suggest, they differ in the number of movements of the piston required to complete each cycle of operation. The simplest is the two-stroke engine. It has no valves. The exhaust from the...
POC is a leading approach to PM emissions control in developing countries because they don't require periodical active regeneration; however, the filter passive regeneration by the NO2 oxidation of soot is needed to maintain filtration efficiency. The fact is that these countries might not use low...
Air-path control of clean diesel engines : for disturbance rejection on NOx, PM and fuel efficiency In this paper, new tuning formulae of the PID controllers for set-point tracking and load disturbance rejection are presented for integrating processes ...

(comprehensive modal emissions model) in foreign countries,then compares the difference between diesel buses in China and standard diesel trucks in CMEM.Some parameters of the model,like speed,acceleration,quality,transmission efficiency and so on are revised,and then the calculating formula which is ...
The maximum efficiency occurred with the combustion of the fuel containing 10% DEE additive when the different DEE ratios took into consideration. Sugash et al. [75] performed a brief study on the investigation of performance and exhaust emissions of DI diesel engine fueled with cottonseed oil ...
The diesel engine is a common powerplant choice when economic factors such as fuel economy, durability and efficiency are prime considerations. To extract the greatest utility from a diesel engine, lubricant drain intervals are often extended in commercial applications to minimize unproductive downtime ...
