--Stringent emission norms and environment degradation due to pollutants from the automotive vehicles lead us to find the suitable alternative for the petro-diesel. Among the alternatives the non-edible vegetable oil seems to be most promising one. When the vegetable oil is used as fuel in diesel engine, it does not cause any major problem if used for a short period. However in the long run it ...

One of the important problems in reducing of pollutant emission from DI and IDI diesel engines is trade-off  between soot and NOx. Split injection is one of the most powerful tools that makes the chance to shift the trade-off curve closer to origin.  At the present work, the effect of split injection on the combustion process and emissions of a cylinder IDI diesel engine under the specification...

introduction: the aim of this study was to evaluate the expression of pinopodes as animplantation marker after ovarian hyper stimulation and progesterone injection using scanningelectron microscopic studies. material and methods: three groups of nmri adult female mice were used in the experiment. the control group (group a) were untreated pseudopregnant mice. group b mice were made pseudopregna...

Precisely detecting puncture times has long posed a challenge in medical education. This is attributable not only to the subjective nature of human evaluation but also insufficiency effective detection techniques, resulting many students lacking full proficiency injection skills upon entering clinical practice. To address this issue, we propose novel method that enables automatic during without...

Fault injection technologies can be utilized to steal secret information inside integrated circuits (ICs), and thus cause serious security threats. Parity check has been adopted as an efficient method against fault attacks. However, the contradiction between overhead restricts further development applications of parity in detection. This paper proposes two methods, mixed-grained word recombinat...

In this paper, the effect of pre-injection timing on combustion and emission performance methanol/diesel high premixed charge compression ignition (HPCCI) mode at low load was studied by three-dimensional numerical simulation. The simulation is carried out under conditions 1900 r/min 25% load, diesel mass remains constant changed 50% 60% methanol ratio respectively. results show that with delay...

The present work investigates the performance and emission characteristics of hydrous methanol fuelled Homogeneous Charge Compression Ignition (HCCI) engine. In the present work a regular diesel engine has been modified to work as HCCI engine. Hydrous methanol is used with 15% water content in this HCCI engine and its performance and emission behavior is documented. A spark plug is used for ass...

Recently, there is an increasing interest in the pyrolysis of waste plastic into usable fuel as a friendly environment method for disposal. The existing literature from various studies stated that major problem related to use WPO diesel engines high NOx emissions level. This paper aims remedy this by suggesting best EGR percentage with advanced optimum injection timing. Primary, 5 fractions are...

From an ecological aspect, the hydrogen has all properties to be a very good fuel for internal combustion engines. However high speed, as well possibility of backfire, is inconvenient port injection. In this paper, influence injection timing on engine working cycle parameters (pressure and temperature) was investigated deeply. The investigation, parameters, performed numerically by application ...
