It was the objective of the VW Passenger Car Diesel Engine Project to alleviate considerably all the ill-famed diesel disadvantages, such as noise, smell, smoke, and slow acceleration, the latter being due to the low horsepower-to-weight ratio. On the other hand, it was intended to preserve for subcompact car use the classical diesel advantages, such as excellent fuel economy, long service life, low incidence of malfunctions, and favorable emissions. One goal was compliance with US emission regulations in addition to meeting requirements worldwide. Compared to a spark ignition engine of the same power output, improvements in fuel economy of the diesel by 30 to 50%, and service life by more than 50% were desired. Another objective was to keep diesel production cost low by using the largest possible number of spark ignition engine parts for diesel production. Of all diesel operating principles, the swirl chamber design was found to comply best with the manifold requirements connected with a subcompact car. By virtue of extensive development work on the spark ignition engine parts, it is ensured that both Otto and diesel engines can be manufactured on the same transfer line.
