Description

This book presents the papers from the latest conference in this successful series on fuel injection systems for internal combustion engines. It is vital for the automotive industry to continue to meet the demands of the modern environmental agenda. In order to excel, manufacturers must research and develop fuel systems that guarantee the best engine performance, ensuring minimal emissions and maximum profit. The papers from this unique conference focus on the latest technology for state-of-the-art system design, characterisation, measurement, and modelling, addressing all technological aspects of diesel and gasoline fuel injection systems. Topics range from fundamental fuel spray theory, component design, to effects on engine performance, fuel economy and emissions.

Chapter 1: Energy prognosis until 2030; reserves; transport fuels

POLITICAL INFLUENCE

POPULATION

WORLDWIDE GDP (+ 2.7 %) IS GROWING FASTER THAN ENERGY CONSUMPTION

ENERGY CONSUMPTION IS GROWING BY 1.2 % P.A

KEY FACTOR ENERGY EFFICIENCY

ELECTRICITY GENERATION REMAINS THE BIGGEST PRIMARY ENERGY CONSUMER

OIL IS DOMINATING THE TRANSPORT SECTOR FAR INTO THE FUTURE

LIGHT VEHICLE CONSUMPTION IS STAGNATING IN SOME REGIONS, HEAVY DUTY PART IS GROWING

LIGHT DUTY VEHICLES IN THE EU ARE NEARLY STAGNATING FROM 2015

ENERGY EFFICIENCY IN THE USA 2030 STILL BEHIND OTHER REGIONS

LIGHT DUTY CONSUMPTION IN THE USA PEAKS IN 2015

CAN THE ADDITIONAL DEMAND FOR OIL BE SUPPLIED FROM THE PRESENT SOURCES?

OIL WILL BE THERE WHEN WE DON'T NEED IT FOR TRANSPORT ANY LONGER
