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 a ....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
An opposed-piston hydraulic free piston engine operating with homogenous charge compression ignition (HCCI) combustion, has been proposed by State Key Laboratory of Engines as a means of significantly improving the IC engine s cycle thermal efficiency and lowering exhaust emissions. Single and multi-zone Chemkin model with detailed chemical kinetics, and unique piston dynamics extracted from one dimensional gas dynamic model, have been used to analyze the combustion characteristics and engine performance. Intake heating, vari ....etc

Dementia in Stroke Survivors in the Stroke Data Bank Cohort

We determined the prevalence of dementia in 927 patients with acute ischemic stroke aged
years in the Stroke Data Bank cohort based on the examining neurologist's best judgment
Diagnostic agreement among examiners was 68% ( K = 0 3 4 ) . Of 726 testable patients, 116 (16%)
were demented. Prevalence of dementia was related to age but not to sex, race, handedness,
educational level, or employment status before the stroke. Previous stroke and previous
myocar ....etc

two stroke engine using reed valves pdf

Abstract
In developing countries a large number of private vehicles used two stroke engines. A large percentage of them employ two stroke engines because of their simplicity, high power to weight ratio and low cost of maintenance. Although two stroke engines are less efficient and more polluting they may continue to popular due to low cost and maintenance.

The most serious drawback of a two stroke S.I. engine is its higher fuel consumption and higher unburned hydrocarbon emissions when compared with fou ....etc
