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

SCRAMJET ENGINE



SCRAMJET

A scramjet (supersonic combustion ramjet) is a variation of a ramjet with the key difference being that the flow in the combustor is supersonic.


The first successful launch (Hyshot II) was of a University of Queensland scramjet on 30 July 2002.

NASA first flew thrust producing scramjet powered vehicle in 2004 with the X-43A. It set a new speed record of 12,144 km/h (7,546 mph), or Mach 9.8, on ..............etc

ABSTRACT

A scramjet (supersonic combustion ramjet) is reminiscent of a ramjet. The basic components of scramjet are inlet, diffuser, fuel injector, flame holder, igniter, and combustion chamber and exhaust nozzle. The basic principle of scramjet is same as that of any type of engine, intake, compression, combustion..............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

In the history of internal combustion engine development, hydrogen has been considered at several phases as a substitute to hydrocarbon-based fuels. Starting from
the 70’s, there have been several attempts to convert engines for hydrogen operation.
Together with the development in gas injector technology, it has become possible to
control precisely the injection of hydrogen for safe operation. Since the fuel cell needs
certain improvements before it is widely used in vehicles, the conventional internal combustion engine is to play an i..............etc
