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

Pistonless pump



INTRODUCTION:

NASA have developed a Low cost rocket fuel pump which has
Comparable performance to turbopump at 80-90% lower cost. Perhaps
the most difficult barrier to entry in the liquid rocket business is the
turbo pump. A turbo pump design requires a large engineering effort
and is expensive to mfg. and test. Starting a turbo pump fed rocket
engine is a c ....etc

PISTONLESS PUMPS IN ROCKETS

Presented By:
MADHU M
(1JS06ME021)


WHAT IS PUMP
Pump is a device which converts mechanical energy into hydraulic energy.
Principle: A partial vacuum created when internal parts of pump receives mechanical energy .
Oil is forced into pump due to atmospheric pressure on oil and suction created by pumping element.
Oil is squeezed b/w pump elements which increases pressure of fluid and then is forced out of pump and the cycle continues.

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

ABSTRACT:
Pistonless pump for rocket has been proved to be the most economical than piston pump or turbopump.
In pistonless pumps, piston is absent. It has very much less rotating parts than that of piston pumps or turbo pumps. So, it has less friction losses and there by it helps to improve the efficiency of the engine considerably.They can be easily installed in the rocket than turbopumps.Also,it reduces the weight of rocket.
