The present disclosure relates to a lubricating composition for a four-stroke engine, with low ash content including: a) one or more base oils selected from oils of Groups I-IV, preferentially from oils of Group III or IV from the API classification, b) at least one compound (b) selected...
The ash-producing detergents are exemplified by oil soluble neutral and basic salts, wherein “basic salt” is used to designate metal salts wherein the metal is present in stoichiometrically larger amounts than the organic acid radical, of alkali or alkaline earth metals with sulfonic acids, ...
The lower acceptable limit of ECN depends on the engine type, but values greater than 20 are considered suitable for both two-stroke crosshead and 4-stroke marine engines [27]. The fuel combustion analyzer also provides information related to the ignition, combustion, and post-combustion ...
When converting these wastes to alcohol fuels using thermal techniques, alkaline metal components act to supply low-melting salts, causing clogging and other ash-related difficulties. In contrast, the fermenting approach can lessen the likelihood of ash issues, which may be a desirable component of ...
Fish were held in 1.5 m3 tanks under a 18:6 h day:night photoperiod and fed 1.5% of the biomass with 6 mm pellets (Yellowtail 6P, EWOS, 48% protein, 20% oil, 0.8% fibre, 9.7% ash) twice daily. Salinity was checked daily using a handheld refractometer. To ensure good water quality...
The occurrence of mixture ignition is typically caused by contact with a hot surface or hot spots (residual gas or oil ash). While the intake valves are opened, this incidence is commonly known as back-firing [19]. This phenomenon may generate the burn-up of the whole H2-air charge, ...
Diabetic microvascular angiopathy is the leading cause of blindness, end stage renal disease and amputations worldwide, as well as myocardial infarction, stroke and peripheral arterial disease. Preventing or delaying microvascular disease could improve the lives of millions, prevent catastrophic illness, ...
