INTRODUCTION CRDi stands for Common Rail Direct Injection meaning‚ direct injection of the fuel into the cylinders of a diesel engine via a single‚ common line‚ called the common rail which is connected to all the fuel injectors. Whereas ordinary diesel direct fuel-injection systems have to build up pressure anew for each and every injection cycle‚ the new common rail (line) engines maintain constant pressure regardless of the injection sequence. This pressure

The aim of this experiment was to investigate the effect that a glucose concentration has on the rate of fermentation. This was done by adding a variety of different glucose concentration into a test tube‚ siting in a water bath. The carbon dioxide would be collected in the test tube and therefore would measure the rate of fermentation. The results parsley supported the hypothesis that‚ “If the glucose concentration increases‚ the rate of fermentation increases‚ therefore the more carbon dioxide

Introduction Eutrophication is an increase in the amount of plant nutrients in a body of water(Ford-2000). A Eutorhication process that takes a long period of time to occur. It involves the transformation of a new lake and an old one. Because it has clear water and low nutrient content the young lake is called oligotrophic‚ and the older lake is different in that it is murky water and has a high level of nutrient‚ which is called atrophic. This process is natural and since it is it takes a long
