Describes the structure and life cycle of the wildflower known as the jack-in-the-pulpit.

Discusses the present internal combustion engine and surveys the research now being done to produce an engine that will not be as much of a pollutant.

Based on previsions, the reciprocating internal combustion engine will continue to be widely used in all sectors: transport, industry, and energy production. Therefore, its development, while complying with the limitations of pollutants as well as CO2 emission levels and maintaining or increasing performance, will certainly continue for the next few decades.In the last three decades, a significant effort has been made to reduce pollutant emission levels. More recently, attention has been given to CO2 emission levels too.It is widely recognized that one single technology will not completely solve the problem of CO2 emissions in the atmosphere. Rather, the different technologies already available will have to be integrated, and new technologies developed, to obtain substantial CO2 abatement.

Seminar paper from the year 2007 in the subject Economy - Environment economics, grade: 1,3, University of Applied Sciences Constanze, course: Environment Economics, language: English, abstract: This essay is about the engines and fuels of the future in the automotive industry. It tries to find out whether these technologies are suitable for the purpose to reduce pollutant emissions. Furthermore, it will consider the potential of the engines/fuels which they can contribute to an sustainable energy supply in the traffic sector, independent of the use of crude oil.
