DESCRIPTION AND OPERATION

EMISSION CONTROL SYSTEMS

Engine design has evolved in order to minimise the emission of harmful by-products. Emission control systems
fitted to Land Rover vehicles are designed to maintain the emission levels within the legal limits pertaining for the
specified market.

Despite the utilisation of specialised emission control equipment, it is still necessary to ensure that the engine is
correctly maintained and is in good mechanical order, so that it operates at its optimum condition.

In addition to emissions improvements through engine design and the application of electronic engine
management systems, special emission control systems are used to limit the pollutant levels developed under
certain conditions. Two main types of additional emission control system are utilised with the Td5 engine to reduce
levels of harmful emissions released into the atmosphere. These are as follows:

•

Crankcase emission control - Also known as blow-by gas emissions from the engine crankcase.

•

Exhaust gas recirculation - To reduce NO
