Diesel vehicles contribute substantially to emissions of NOx, an ozone precursor, and to particulate matter. Real-world in-use on-road emissions of selected diesel vehicles, fueled with B20 biodiesel and petroleum diesel, were measured during normal duty cycles using a portable emissions measurement system. Four categories of dump trucks were tested, including: (1) single rear axle with Tier 1 ...
nowadays, technical terminology translation plays an important role in human life. specific groups of people all over the world refer to learn these terminologies in order to be familiar with a subject and improve their knowledge in that domain. on the other hand, saving the technical translation equivalent is a particularly salient challenge for technical translators. the present study was con...
It was suggested in a previous study that cells of Acinetobacter venetianus VE-C3 adhere to diesel fuel by synthesizing a capsular polysaccharide containing glucose and/or mannose. To study the fine structure of cells and localization of bacterial polysaccharide in the presence of diesel fuel, two lectins were used: ConA, an agglutinin from Canavalia ensiformis specific for mannose and/or gluco...
To help understand the complex fuel spray combustion phenomena in modern diesel engine using high injection pressure, a fuel injection test bench and a constant volume combustion chamber were developed and demonstrated in this study for diesel spray diagnostics. Both facilities are significant when linking between spray injection and combustion dynamics and engine performance. This link is impo...
The purpose of this study is to determine the optimum intake valve closing time of a large diesel engine having lower fuel consumption and lower NOx emission. The performance simulation has been conducted for this purpose, and a phenomenological combustion model is verified by experimental data of heat release rate and NOx emission in order to enhance the prediction quality of the performance s...
this study aimed to investigate the effects of listening strategy training on iranian efl learners listening comprehension and use of such strategies. this work, employing an experimental methodology, was conducted among 60 adult efl learners from a language institute in isfahan, iran, as participants. the participants, who were selected based on the results of a placement test, were assigned t...
teachers beliefs have usually been left unattended in the realm of educational research in iranian context. one of those beliefs which seems to impact teachers performance in the classroom is their sense of self-efficacy, which refers to teachers belief in their ability to enhance student achievement and in bringing about positive learning outcomes. the present study aimed to investigate the pr...
The paper investigates the result on the existing diesel engine that can suitably modified to operate on the diesel fuel mode to conserve diesel and also reduce environmental pollution. The conventional fuels, petrol’s and diesel for internal combustion engines are exhausted at an alarming rate, due to increase of vehicle population and also these fuel causes environmental problems. Make these ...
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
Increased energy demand and the concern about environment friendly technology, renewable bio-fuels are better alternative to petroleum products. In the present study linseed oil was used as alternative source for diesel engine fuel and the results were compared with baseline data of neat diesel. Performance parameters such as brake thermal efficiency (BTE) and brake specific fuel consumption (B...
