EFFECT OF NEGATIVE SUPERCHARGING ON INTERNAL COMBUSTION
ENGINE


ABSTRACT
Until recently, Automobile manufacturers uses supercharger & turbocharger to supply
air-fuel mixture at a pressure above atmospheric. Up to 40% increase in power & torque may be
obtained by supercharging. As a typical example , in the Chrysler 2.2L turbocharged engine, the
turbocharged provides 35% more torque & 50% more power compared to the same engine
without turbocharger. To achi ....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 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

NEGATIVE SUPERCHARGING


INTRODUCTION

WHAT IS MEAN BY SUPERCHARGING ?

IN THE NEGATIVE SUPERCHARGING PROCESS, POSITIVE EXHAUST PRESSURE CONVERTED INTO NEGATIVE BOOST TO PULL MORE AIR INTO THE ENGINE.

OPPOSITE TO CONVENTIONAL SUPERCHARGING.

Negative Supercharging




INTRODUCTION



Negative Supercharging is a highly advanced and complex Thermo Fluid Dynamic Process that converts the positive exhaust pressure produced after combustion into Negative Boost within the cylinders to pull more air into the engine. Negative Supercharging does NOT use any type of blower device and works the opposite to conventional supercharging by pulling air into the engine instead of pushing air like convention ....etc

ABSTRACT


The engines that are used now a days spot a constant compression ratio. It is economic for the compression ratio must decrease with the speed. But there is a practical difficulty for the engines to alter its compression ratio while in working. But there has been a break through, researchers have found out new ways by which the compression ratio can be altered. Thus comes a new breed of engines called the Variable Compression Ratio Engines. Volkswagen has come up with a production version too. In this type the ....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
