An internal combustion engine works by drawing a mixture of air and fuel (the intake charge) into its cylinders, compressing that mixture, and then burning it. The more air/fuel mixture that can be crammed into the cylinders to burn, the more power the engine produces. You can increase power in three basic ways: you can improve the engine s ability to draw more air and fuel into the cylinders and expel its burned exhaust gases (its volumetric efficiency, or breathing ); you can increase the swept volume of the cylinders (the engine s displa ....etc

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 conventional superchargers and turboch ....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.

COMBUSTION STROKE

EXHASUT VALVE OPENS
VELOCITY INCREASES IN TRI-Y HEADER(TWICE)

EXHAUST STROKE

.EXHAUST VALVE CLOSES EARLY.
.REDUCED OVERLAP DURATION
.LESS EXHAUST VALVE LIFT

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 achieve above purpose, air ....etc

Nano-Optical Superlenses with Negative-Index Sandip Tiwari, Cornell U Metamaterials
We have demonstrated experimentally the imaging at 1.55 m wavelength by a generalized photonic crystal superlens (Fig. 1) nanofabricated in InGaAsP/InP heterostructure. By designing a suitable lens surface termination, an image spot size of 0.12 2 was achieved, demonstrating superlens imaging with sub-wavelength resolution well below the diffraction limit (0.5 2).

We have created a new nano-optical microlens that focuses infrared light at telecom ....etc

Abstract:
Deregulation of the electric utility has created unprecedented opportunities for the growth in the market for alternator. In order to extract the maximum benefit from this situation improvement must be made in the control and protection features incorporated in alternator. The automatic voltage regulator has a key role to improve alternator performance. This project investigates the current and voltage characteristics of the ....etc
