ABSTRACT
Although current systems relay almost exclusively on mixture formation outside the combustion chamber, concept based on internal mixture formation. With the fuel being injected directly into the combustion chamber were actually the foundation for first gasoline injection system. As there system are superb instruments for achieving further reductions in fuel consumption. There are now becoming an increasingly significant factor.

E85 is an alcohol fuel mixture of 85% ethanol and 15% gasoline, by volume. ethanol derived from crops (bioethanol) is a biofuel.
E85 as a fuel is widely used in Sweden and is becoming increasingly common in the United States, mainly in the Midwest where corn is a major crop and is the primary source material for ethanol fuel production.
E85 is usually used in engines modified to accept higher concentrations of ethanol. Such flexible-fuel engines are designed to run on any mixture of gasoline or ethanol with up to 85% ethanol by volume. The pr ....etc

INTRODUCTION
In recent years, legislative and market requirements have driven the need to reduce fuel consumption while meeting increasingly stringent exhaust emissions. This trend has dictated increasing complexity in automotive engines and new approaches to engine design. A key research objective for the automotive engineering community has been the potential combination of gasoline-engine specific power with diesel-like engine efficiency in a cost-competitive, production-feasible power train. One pr ....etc

Gasoline direct injection or GDI is a variant of fuel injection employed in modern four stroke petrol engines. The gasoline or biobutanol is injected right into the combustion chamber of each cylinder, as opposed to conventional multi point fuel injection that happens in the intake manifold.

GDI enables stratified charge (ultra lean burn) combustion for improved fuel efficiency and emission levels at low load. Further improving efficiency and high-load output-power, the engine power is governed by modulating fuel injection, like a diesel eng ....etc

SUPERCHARGERS AND TURBOCHARGERS
What is a super charger?
A supercharger is an air compressor used for forced induction in internal combustion engines.
Need for supercharger……….
Heat loss: to the environment and in the form of flue gasses .
Increased Work O/P: to increase the work o/p per cycle by increasing the total mass flow rate.
Altitude effect: with the rise in altitude , power o/p of the IC engines fell considerably due to lesser availability of oxygen.
History……….
By the late ....etc

Abstract
This paper presents a critical review of the recent combustion advancements made in gasoline engines for the reduction of fuel consumption
and engine-out emissions, and the technologies associated with these advancements. For optimum combustion throughout
their speed/load range, engines should operate in three combustion modes: stratified-charge spark-ignited (SCSI), homogeneous-charge
spark-ignited (HCSI), and homogeneous-charge compression-ignited (HCCI). Key technologies to achieve this, with maximum reduction
in fuel co ....etc
