in this work, result of experimental investigation on interaction of fuel spray generated by a swirled type injector, with air motion in a prototype cylinder are presented. experiments were carried out by planar imaging and particle image velocimetry (piv) techniques in order to provide information about the spray structure evolution and instantaneous velocity distribution of air motion and fue...

homogenous charge compression ignition (hcci) combustion is spontaneous multi-site combustion of a nominally premixed air/fuel mixture that exhibits high rate of pressure rise and short combustion duration. to avoid excessive pressure rise rate and knocking, hcci engines are fueled with highly diluted mixture using a combination of excess air and/or egr. hcci combustion is attractive due to ext...

Turbulent multiphase combustion plays an important role in both nature (e.g., volcanos and pool fires) industry industrial furnaces, aeroengines, internal engines). It is a highly complex multiscale multi-physicochemical process which interactions between the dispersed continuous phases, phase change, droplet collisions, evaporation, mixing, heat transfer, chemical reactions occur simultaneousl...

The heating value of fuel is one of its most important physical properties, and is used for the design and numerical simulation of combustion processes within internal combustion (IC) engines. Recently, there has been a significant increase in the use of dual fuel and blended fuels in compression ignition (CI) engines. Most of the blended fuels include biodiesel as one of the constituents and h...

1.1 Background Thanks to the breakthroughs in microfabrication technologies, numerous concepts of microsystems including micro aerial vehicles, microbots, and nanosatellites have been proposed. Contrary to ordinary electronic devices, these microsystems perform mechanical work and require the extended operation. As their functions are getting complex and advanced, their energy consumption is al...

Here we show that rolled-up and electroplated catalytic microjet engines undergo dramatic corrosion in fuel solution.

In this era of depleting fossil fuels, alternative fuels and their study has gained much importance. One the methods using is operating IC engines in dual fuel mode. This review an attempt to highlight investigations on HHO gas supplemented combustion internal engines, particularly diesel operated ones. better burning characteristics than pure hydrogen since, oxygen does not attain diatomic sta...

This paper was to answer a fundamental question on whether LNG truly contribute reducing environmental impacts from shipping activities. Given this, it intent determine the holistic association between and impacts. An enhanced method, known as parametric trend lifecycle assessment, introduced. To obtain general observation, analysis coupled with extensive dataset of over 7,000 ships consisting ...
