Traditionally, diesel engines have always been seen as noisy, smelly and
underpowered engines of little use other than in trucks, taxis and vans. But as
diesel engines and their injection system controls have become more refined,
the 1980s have seen that situation change. In the UK in 1985 there were almost
65,000 diesel cars sold (about 3.5 per cent of the total number of cars sold),
compared with only 5380 in 1980.
There are various ways of attaching the wheels of the car so that they can move up and down on their springs and dampers, and do so with as little change as possible in the distance between adjacent wheels or in the near-vertical angle of the tyres to the road.
