ABSTRACT
Since two-three decades, hydrogen has been identified as a versatile potential fuel competent to the conventional fuel such as gasoline. In order to implement it fully and to develop the combustion based power devices which may supply much higher energy density than others, the understanding of hydrogen air combustion mechanism is very essential. In this seminars, Computational Fluid Dynamics (CFD) based numerical simulations have been performed to study the combustion of non-premixed hydrogen- ....etc

HFO 1234 YF AS AN ALTERNATIVE REFRIGERANT FOR AUTOMOTIVE AIR CONDITIONING
ABSTRACT
HFO 1234 YF is a fluorinated hydrocarbon with the formula CH2=CFCF3. It has been replaced for R-134 as a refrigerant in Automobile Air Conditioner .HFO 1234 YF highly energy efficient, exhibits low toxicity, and can be potentially used in direct expansion automotive A/C systems with minimal design modifications . The Pres ....etc

INTRODUCTION

A. Relevance :-
The economic of India depends to a large extent on the wheels of transport. The specter of economy ruin due to depleted oil reserves has changed the interest of scientist and research work towards alternative fuels for motor vehicle. Viable substitute for motor spirit are gaseous hydrocarbons, hydrogen gas, alcohol & electricity that run on hydrocarbon gas & electricity are still in the experimental stage. While alcohol is used as a fuel chiefly in Brazil, it?s feas ....etc

ELECTRONIC FUEL INJECTION SYSTEM


1. INTRODUCTION

 In developed and developing countries considerable emphasis is being laid on the minimization of pollutants from internal combustion engines. A two-stroke cycle engine produces a considerable amount of pollutants when gasoline is used as a fuel due to short-circuiting. These pollutants, which include unburnt hydrocarbons and carbon monoxide, which are harmful to beings. Ther ....etc
