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

ABSTRACT
The Present scenario of Fuel Consumption is well known to everyone. Everyday
technical people talk about the depleting Fuel sources and Exhaust hazards.
Particularly about the Diesel engines find their importance more than the Petrol
engines due to their operating cost and Fuel consumption But Diesel engines have
their demerits in the area of Exhaust and Power loss. Necessary steps have to be
taken in order effectively use the Fuel available. We have brought the UTILIZATION
OF SIX STROKE ENGINES which ....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

Nowadays search engines provide the easiest way to
reach information resources that are available on the Web.The
number of Internet users has been growing dramatically all
over the world. Nevertheless, as for those who can not use
computers and the Internet, mobile search engine plays a great
role in offering the service. In this case, it quickly attracts
people's attention because it is unique. Mobile search is
extension to the search engine in the mobile terminal and is
also an important development trend in the fut ....etc

Valvetronic Engine Technology



One of the latest and interesting innovations in the field is the Valvetronic Engine Technology from BMW. The 316ti compact is the first production car in the world featuring an engine controlled by VALVETRONIC air supply. Accordingly, the VALVETRONIC engine no longer requires a throttle butterfly, which has quite literally restricted the free ventilation of the internal combustion engine ever since its invention. Now VALVETRONIC replaces this conventional function by infinitely variable intake valve lift, o ....etc

Abstract—

Most psycho-acoustic models for coding applications
use a uniform (equal bandwidth) spectral decomposition
as a first step to approximate the frequency selectivity of the
human auditory system. However, the equal filter properties
