The exhaust of an automotive engine is one the main causes air pollution. These days, many researchers are investigating waste heat recovery engines. A two-cylinder gamma-type Stirling chosen for this purpose. a diesel as input source This work explains isothermal, ideal adiabatic, and non-ideal simple analysis engine. set differential equations solved using Runge-Kutta 4 th order method MATLAB...

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...

Reducing fuel consumption and carbon emissions in the development of ship propulsion systems following required Energy Efficiency Design Index (EEDI) has become a concern for fishing industry as determined by International Maritime Organization (IMO). This study analyzes suitability using 30 GT vessel propeller engine optimum efficiency. The analysis focuses on developing system selection model...

A yet-to-be-solved but very vital problem in forensics analysis is accurate memory dump data type reverse engineering where the target process is not a priori specified and could be any of the running processes within the system. We present a lightweight system-wide solution that extracts data type information from the memory dump without its past execution traces. Our proposed solution constru...

Recently, the high-pressure fuel injection performance of common-rail direct injection (CRDi) engines has become more important, due to the need to improve the multi-injection strategy. A multiple injection strategy provides better emission and fuel economy characteristics than a normal single injection scheme. The CRDi engine performance changes with the type of high-pressure electro-mechanica...

in this study it has been tried, to compare results and convergence rate of sensitivity analysis and conjugate gradient algorithms to reduce fuel consumption and increasing engine performance by optimizing the timing of opening and closing valves in xu7/l3 engine. in this study, considering the strength and accuracy of simulation gt-power software in researches on the internal combustion engine...

In this paper, a comparison of exergetic models between two hot air engines (a Gamma type Stirling prototype having a maximum output mechanical power of 500 W and an Ericsson hot air engine with a maximum power of 300 W) is made. Referring to previous energetic analyses, exergetic models are set up in order to quantify the exergy destruction and efficiencies in each type of engine. The repartit...

This paper reports on a transaction log analysis of the type and topic of search queries entered into the search engine Google (Australia). Two aspects, in particular, set this apart from previous studies: the sampling and analysis take account of the distribution of search queries, and lifestyle information of the searcher was matched with each search query. A surprising finding was that there...
