1.ABSTRACT
This proposal relates to conceptual design of “Valved Two Stroke Engine with Extended Expansion” . This is an hybrid of two stroke and four stroke engine.
We know that in a two stroke engine - the four strokes viz. suction, compression, power and exhaust will be completed in each rotation of crank shaft and power is produced for each rotation. Whereas in a four stroke engine the above four strokes are completed in every two rotation and power is produced once in a two rotation. Hence for same siz ....etc

Abstract

Here, students learn that energy can be harvested or scavenged from the surrounding environment, in sufficient quantities for use in powering embedded systems. In the laboratory, students design and build a system using Lego pieces and a piezoelectric buzzer that harvests energy from vibrations and uses the energy to charge a battery. Along the way, the students learn about dc motors, cams and gears, piezoelectric material, and circuits for charging.

ABSTRACT


Fresh charge loss during the scavenging process of a two stroke S.I engine is known to be the principal reason for its high specific fuel consumption and high hydrocarbon emission. In order to minimize the fresh charge loss to the exhaust a new scavenging system had been developed. To achieve better performance from this scavenging system, control of air flow through reed valve is necessary, since it will affect the mixture quality of the trapped charge. In this paper, improved performance and reduction in exhaust emissions ....etc

Introduction

A two stroke engine is one which completes its cycle of operation in one revolution of the crankshaft or in two strokes of the piston. In this engine the function of the intake and exhaust processes of the four stroke engine are taken care by the incoming fresh charge which is compressed either in the crank case or by means of a separate blower while the engine piston is near the bottom dead centre. The engine piston needs only to compress the fresh charge and expand the product of combustion.

Abstract—Dynamic Spectrum Access can enable a secondary user in a cognitive network to access unused spectrum, or whitespace, found between primary user transmissions in a wireless network. The key design objective for a secondary user access strategy is to “scavenge” the maximum amount of spatio-temporally fragmented whitespace while limiting the amount of disruption caused to the primary users. In this paper, we first measure and analyze the whitespace profiles of an 802.11 network (using ns-2 simulation) and a non-802.11 (CSMA)-based n ....etc
