The more stringent regulations for diesel engine emissions lead to the requirement that both fuels and engines must be developed jointly. In future, so-called designer will help achieve limits.In our research, conventional fuel, biodiesel, Swedish low sulfur fuel MK1 a specially designed were compared using DaimlerChrysler engine, running modes of ECE 49 test cycle. results regulated non-regulated gaseous emissions, particulate matter size distributions as well mutagenic effects particle...
Research on renewable fuels has to assess possible adverse health and ecological risks as well conflicts with global food supply. This investigation compares the two newly developed biogenic diesel hydrotreated vegetable oil (HVO) jatropha methyl ester (JME) fossil fuel (DF) rapeseed (RME) for their emissions bacterial mutagenic effects. Samples of exhaust constituents were compared after combustion in a Euro III heavy duty engine. Regulated analyzed particle size number distributions,...
Abstract Although fed‐batch suspension culture of animal cells continues to be industrial importance for the large scale production pharmaceutical products, existing control concepts are still insufficient. Changes in cell metabolism during cultivation and between similar cultivations, complexity metabolism, lack on‐line state variables restrict transfer available strategies established bioprocess engineering. A process strategy designed achieve optimized must account all these difficulties...
In Germany, 100,000 tons of biodiesel (rapeseed oil methylester) were produced in 1998. More than 200,000 tonsare expected 2000. the U.S., derives from both rapeseed and soybean oil. The esters these oils areabbreviated RME SME. It is necessary to judge environmental health effects that derive use biodieselin combustion engines. Therefore, regulated some important nonregulated emissions different blends andfossil diesel fuel determined. With regard current discussion about particle size...
Measurement errors often lead to large uncertainties in parameter estimation for dynamical systems. However, a considerable improvement of the preciseness may be obtained by suitable choice experimental conditions. An approach is given calculate optimal input functions solving minimization problem, based on calculation Fisher information matrix. This applied model describing growth plant cells suspension culture stirred tank reactor. The simple metabolic structure, limiting rates, mass and...
Abstract Exhaust emissions and their effects on the environment human health, such as mutagenicity of particulate matter (PM) ozone‐forming potential, must be considered when using an alternative fuel. In present work, a test engine two agricultural tractors ran rapeseed oil methyl ester (biodiesel) or conventional diesel fuel well blends thereof. The objective was to detect any disproportionately positive negative depending blend levels, because biodiesel can blended in every ratio....
Concerns about adverse health effects of diesel engine emissions prompted strong efforts to minimize this hazard, including exhaust treatment by oxidation catalysts (DOC). The effectiveness such measures is usually assessed the analysis legally regulated components. In recent years additional analytical and toxicological tests were included in test panel with aim fill possible gaps, for example, mutagenic potency polycyclic aromatic hydrocarbons (PAH) their nitrated derivatives (nPAH).This...
Abstract To investigate influences of fuel design on regulated and non‐regulated emissions heavy‐duty diesel engines, a Mercedes‐Benz OM 906 Euro 3 engine was run with common (DF), first‐ second‐generation alternative fuels (Gas‐to‐liquid (GTL) as prototype for biomass‐to‐liquid (BTL)), blends these. Secondly, an IVECO (Industrial Vehicles Corporation) Tector F4A 4 test equipped urea based selective catalytic reduction (SCR) pilot series system subjected to 1000 h endurance using...
Many biotechnical processes can be modelled in principle, but the model parameters are not known exactly because of changing media composition or strain variability. Therefore, application filter, control prediction algorithms demands for a repeated parameter estimation from time to during fermentation run. But all complex estimated on-line at each particular on basis data sampled so far, process may show different physiological states like substrate saturation limitation measurement...
