Your A to Z of motoring gobbledygook
E Marking
All car tyres sold from 1st July 1997 must carry an 'E' marking. They certify that the tyre complies with the dimensional, performance and marking requirements.
Emissions
The various gases that are pumped out of a car's exhaust pipe include carbon monoxide, nitrogen oxides and hydrocarbons, although the one to worry about for company car users is carbon dioxide (CO2). The more CO2 your company car produces, the more tax you pay for using it.
Engine capacity
The total volume of all the cylinders in a car's engine added together and expressed in cubic centimetres (cc) or, more frequently, litres. So, an engine with a capacity of 1598cc will be referred to as a 1.6 litre unit. Generally, the bigger an engine's capacity, the more performance it will be able to produce.
Engine management system
An electronic box which monitors the operation and performance of your engine. Sophisticated braking and traction aids may also be linked to the management system so that it can coordinate their operation with that of the engine.
