REDUCED EMISSIONS OF OXIDES OF NITROGEN IN SHIP ENGINES




INTRODUCTION

Oxides of nitrogen emission from ship engines are significant on a global level. These emissions participate in the formation of photochemical smog and acid rain. Here we look at to some ways by which these emissions can be reduced

Mechanism of NOx Formation in Diesel Engines

At the temperature of the Burning of fuel spray (about 2000 K to 2500 K).
Nitrogen + Oxygen Oxides of Nitrogen

noise control in ic engines ppt

Abstract
Noise control is becoming increasingly important for a wide variety of OEM designers. Examples of products that take noise control considerations into account during their design cycles include equipment such as computer hard drives, house appliances, material handling and transportation equipment etc,. In the transportation market, which includes aircraft, ground and marine segments, the demand is for low noise level goals.

Achieving these goals is of primary importance for OEM to be continue to be co ....etc

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 Diesel 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 MAN B&W takes a ....etc

NON CONVENTIONAL I.C ENGINES

INTRODUCTION:

Engine: An engine is a device which transforms one form of energy in to another form. Normally most of the engines convert thermal to mechanical work and are called heat engines.

Heat Engines: It is a device which transforms chemical energy of a fuel into is Thermal energy and utilizes this to perform useful work. Thus, this Thermal energy converted to mechanical energy and are called heat engines.


Heat engines are classified in to two types:
1. IC engi ....etc

CAMLESS ENGINES A NEW APPROACH IN I.C.ENGINES
internal combustion comprise the valve train hardware . In the camless valvetrain, the valve motion is controlled directly by a valve actuator there's no camshaft or connecting mechanisms. Various studies have shown that a camless valve train can eliminate many otherwise necessary engine design trade-offs.Automotive engines equipped with camless valvetrains of the electrohydraulic and electro-mechanical type have been studied for over twenty years, but produc ....etc

ADVANCED NOISE REDUCTION FOR MOBILE TELEPHONY

INTRODUCTION
Have you ever used your mobile phone to place a call from a noisy place and been asked to call back from someplace quieter

It would be great if the phone would mute the background noise for you
This can be done by advanced multi microphone noise suppression algorithm working with principle of human hearing system.

EFFECT OF NOISE
If the environment is noisy
It will enter into microphone so that it become difficult for the person on ....etc

ABSRACT
HCCI has characteristics of the two most popular forms of combustion used in IC engines: homogeneous charge spark ignition (gasoline engines) and stratified charge compression ignition (diesel engines). As in homogeneous charge spark ignition, the fuel and oxidizer are mixed together. However, rather than using an electric discharge to ignite a portion of the mixture, the concentration and temperature of the mixture are raised by compression until the entire mixture reacts spontaneously. Stratified charge compres ....etc
