Reactivity controlled compression ignition (RCCI) is a highly efficient and clean combustion concept, which enables the use of wide range renewable fuels. Consequently, this promising dual fuel concept great interest for realizing climate neutral future transport. RCCI very sensitive operating conditions requires advanced control strategies to guarantee stable safe operation. For real-world imp...

The present study involves the simulation of a constant volume, non-premixed, hot surface spray combustion diesel fuel for given set injection pressure, compressed air pressure (cylinder pressure) and temperature (hot plate temperature) their effects on ignition delay period. Fuel was varied from 100 bar – 300 in steps bar, cylinder range 20 to 40 (in 10 bar) 623 K 723 (50 steps). problem solve...

This paper describes the simulative approach to calibrate an already extremely highly turbocharged industrial diesel engine for higher low-speed torque. The engine, which is operating at its cylinder-pressure maximum, achieve close 30 bar effective mean pressure through suitable calibration between compression ratio, piston-bowl shape and injection strategy. basic idea of study lower ratio even...

The objective of this paper is to investigate the effect of fuel injection pressure on power performance and fuel consumption of diesel engine. In a diesel engine, fuel injection pressure is an important aspect of the engines’ power performance in order to obtain combustion treatment. The experiments in this paper are performed on a four-cylinder two-stroke direct injection diesel engine. The d...

We report for the first time on the use of water-continuous emulsions stabilized by a bio-based macromolecule in a compression-ignition diesel engine and compare their performance, combustion and emissions against the base fuels (diesel, biodiesel, and jet fuel). For this purpose, high internal phase ratio emulsions (70:30 fuel-to-water) were produced by mechanical emulsification using carboxym...

The exhaustion of worldwide oil reserves has created an incipient need to find hopeful alternative fuels for the future. Substantial research been done in this direction, and all studies by researchers have provided results that proved growing potential biofuel as a popular CI engine. current investigation explores derived from wasteland tree Prosopis juliflora (Karuvalam seeds). Experimentatio...

It has been suggested that the kinematics of a reach-to-grasp movement, performed within an action sequence, vary depending on the action goal and the properties of subsequent movement segments (action context effect). The aim of this study was to investigate whether the action context also affects action sequences that consist of several grasping movements directed toward different target obje...

A foundational theorem of Laman provides a counting characterisation of the finite simple graphs whose generic bar-joint frameworks in two dimensions are infinitesimally rigid. Recently a Laman-type characterisation was obtained for frameworks in three dimensions whose vertices are constrained to concentric spheres or to concentric cylinders. Noting that the plane and the sphere have 3 independ...

It has been proposed that the outer cylinder of the drift chamber be changed from 1.6 mm carbon fiber (0.6% X0) to 2.5 mm aluminum (2.5% X0). While such a change would have only a slight effect on the barrel CsI calorimeter performance, the question has been raised as to how it might affect the DIRC. Multiple scattering in the outer cylinder would cause as uncertainty in the entrance angle and ...

PURPOSE The aim of the present study was to evaluate the accuracy of three techniques for correction of cast implant bars. MATERIALS AND METHODS Thirty cast implant bars were fabricated on a metal master model. All cast implant bars were sectioned at 5 mm from the left gold cylinder using a disk of 0.3 mm thickness, and then each group of ten specimens was corrected by gas-air torch soldering...
