METALLURGICAL CHANGES IN STEELS DUE TO CRYOGENIC PROCESSING & ITS APPLICATIONS

Metallurgical changes in steels due to cryogenic
processing & its applications

Abstract:
Cryogenic processing is a supplementary process to conventional heat treatment process in steels. It is an inexpensive one time permanent treatment affecting the entire section of the component unlike coatings. Though the benefits have been reported widely, there are issues debated upon, in respect of the treatment parameters, extent of benefits ex ....etc

POLLUTION FROM SI ENGINES & THEIR CONTROL


Major Sources:

Dirunal Emissions

Take place from fuel tanks and carburetor float bowls
(in engines fitted with carburetors) of parked vehicles.

It draws in air at night as it cools down

Expels air and gasoline vapour as it heats up during the day.

These could be up to 50g per day on hot days.


Running Losses

Gasoline vapours are expelled from the tank (or float bowl)

ME Engines “ the New Generation of Diesel Engines

INTRODUCTION

The introduction of the electronically controlled camshaft-less low speed diesel engines, which is now gaining momentum, is a milestone in diesel technology that deserves a place in history like Rudolf Dieselâ„¢s first engine in Augsburg, the 1912 motor vessel Selandia, the introduction of turbocharging on two-stroke diesels in 1954, and the first SCR (Selective Catalytic NOx Reduction) systems on ships in 1989. This paper will outline how MA ....etc

estimation of errors due to reduction in modal superposition method. Mode superposition methods are used to calculate the dynamic response of linear systems. In modal superposition method, it becomes unnecessary to consider all the modes of a particular system. In generally only a few number of modes contribute significantly to the solution. The main aim of the study is to identify the significant modes required for good approximation.

Thermophoresis is a phenomenon of the movement of small particles in a gas with a temperature gradient towards the cooler region of the gas. Small particles, such as dust, when suspended in a non-isothermal gas, experience a force in the direction opposite to the temperature gradient. This force, known as the thermophoretic force plays an important role in the mass transfer mechanism of several devices involving sub-micron and micron sized particles and a large thermal gradient, and it is often cited as an important one influence the efficiency ....etc

EVALUATION UNAVAILABILITY DUE
TO AGING FAILURES



Abstract

The paper presents a method to evaluate unavailability due to aging failures and incorporate that in power system reliability evaluation. it use of normal and weibull distribution for modeling aging failures probability distribution functions. The defined unavailability of aging failures has a consistent form which is the same as that for repairable failures.

INTRODUCTION

There are two failure modes for a power system component: 1) r ....etc

Abstract
Homogeneous charge compression ignition (HCCI) is a form of internal combustion in which well-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. Homogeneous charge compression ignition (HCCI) engines have
the potential for high efficiencies and low pollutant emissions.By comparison with spark ignition (SI) engines, for example,HCCI engines can yield a 15-20% increase in fuel economy while emitting lower levels of oxides of nitrogen (NOx).HCCI engines can also achieve thermal eff ....etc
