Abstract
Light duty diesels are often criticised for their poor specific power but boosting can be used to improve the situation.
An exercise was carried out in which the performance of a naturally aspirated diesel car was compared with identical vehicles fitted with turbocharged and Comprex® boosted engines.
The measures necessary to apply the two boosting systems to the engines are described and the test bed performance obtained is shown for each case. Standard vehicle tests were made with each system and the performance, fuel consumption, noise and emissions results are compared.
