High Efficiency Miller Cycle Gas Engine
1. INTRODUCTION
The output of gas engines for cogeneration mainly ranges from 100 to 1 000 kW. The present gas engines are broadly classified in two types: lean-burn system (1) and stoichiometric air-fuel ratio combustion system, with the lower output engines using the stoichiometric Air-fuel ratio combustion system while the medium and large size engines adopting the lean-burn system. The lean-burn system generally features in high generating efficiency and low NOx emission in ad ....etc

Abstract:
The billions of dollars of Commercial banks losses to check frauds make automatic verification of signatures of checks a major requirement in the new Interbank Check Imaging(ICI) environment. In this seminar we shed some light on the problem of check fraud, and introduce the application of an ASV method to the security of the financial transactions in electronic banks. The problem of transferring ASV research into an applicable system that can be integrated into electronic banks environment, with its implications, is dealt with in ....etc

Gerardo Vázquez, Student Member, IEEE, Emiliano Aldabas, Member, IEEE


ABSTRACT:
There is a strong trend in the photovoltaic (PV) inverter technology to use transformer less topologies in order to acquire higher efficiencies combining with very low ground leakage current. In this paper a new topology, based on the H Bridge with a new AC bypass c ....etc

Abstract:
new power machine concept has been designed and analyzed for production, and proof of principle subscale tests have been performed, with positive results. The machine design concept is applicable as a compressor, pump, motor, or engine. Simplicity of design based on spherical ball pistons enables a low moving part count, high power to weight ratio, elimination of valve train and water cooling systems, and perfect dynamic balance.

The new design concept utilizes novel kinematic design to completely eliminate inertial loads that w ....etc

INTRODUCTION
A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process. Water is a useful and cheap medium for transferring heat to a process. When water is boiled into steam its volume increases about 1,600 times, producing a force that is almost as explosive as gunpowder. This causes the boiler to ....etc
