SYNOPSIS
The anti-knock quality of the gasoline fuel used in spark ignition internal combustion engine can be enhanced by the addition of lead alkyls . But it causes formation and emission of toxic lead compounds . These lead alkyls can be replaced by high octane , oxygen containing organic compounds called oxygenates. The physical and chemical properties of oxygenates influences the performance and combustion products of gasoline-oxygenate blends. This paper offers a comparision between the oxygenated a ....etc

VALVETRONIC ENGINE TECHNOLOGY
1. INTRODUCTION
The automobile has been providing individual mobility for more than 100 years. This mobility is made possible first and foremost by combustion engines drawing their power from fossil energy carriers, which, even today, provide the foundation in generating mechanical drive power in the automobile. The primary objectives in developing drive systems are to curb fuel consumption and reduce CO2 emissions. In an effort to meet this challenge, the automotive industry is developing suit ....etc

High Efficiency Miller Cycle Gas Engine
1. INTRODUCTION
The output of gas engines for cogeneration mainly ranges from 100 to 1 000 kW. The present gas engines are broadly classified in two types: lean-burn system (1) and stoichiometric air-fuel ratio combustion system, with the lower output engines using the stoichiometric Air-fuel ratio combustion system while the medium and large size engines adopting the lean-burn system. The lean-burn system generally features in high generating efficiency and low NOx emission in ad ....etc

CHEMICAL ROCKET ENGINES
1. INTRODUCTION
Chemical rocket engines, like those on the space shuttle, work by burning two gases to create heat, which causes the gases to expand and exit the engine through a nozzle. In so doing they create the thrust that lifts the shuttle into orbit. Smaller chemical engines are used to change orbits or to keep satellites in a particular orbit. For getting to very distant parts of the solar system chemical engines have the drawback in that it takes an enormous amount of fuel to deliver the p ....etc

ABSTRACT
The green engine is one of the most interesting discoveries of the new millennium. It has got some unique features that were used for the first time in the making of engines. This engine is a piston less one with features like sequential variable compression ratio, direct air intake, direct fuel injection, multi-fuel usage etc. The efficiency of this engine is high when compared to the contemporary engines and also the exhaust emissions are near zero. The significance of the engine lies in the efficiency when the ....etc

MPFI ( multi point fuel injection system ) Vs CRDI(Common rail direct injection system)

(Actually an open office format. Use open office to open it)
MPFI : mean multi point fuel injection system ie. in petrol engine for gaining more uniform Air Fuel blending fuel is injected at various point in the path of air. this tech is used in light weight car running on petrol. there is also milage improvement due to this.

but in case of DTSI(digital twin spark ignition) : the
engine cylinder consist of two no of spark plu ....etc
