DESCRIPTION AND OPERATION
GENERAL
The Td5 diesel engine is a 2.5 litre, 5 cylinder, in-line direct injection unit having 2 valves per cylinder, operated by
a single overhead camshaft. The engine emissions on pre EU3 models comply with ECD2 (European Commission
Directive) legislative requirements. EU3 models comply with ECD3 legislative requirements. Both units employ
electronic engine management control, positive crankcase ventilation and exhaust gas recirculation to limit the
emission of pollutants. The unit is water cooled and turbo-charged and is controlled by an electronic engine
management system.
The cylinder block is a monobloc cast iron construction with an aluminium stiffening plate fitted to the bottom of the
cylinder block to improve lower structure rigidity. The cylinder head and sump are cast aluminium. An acoustic
cover is fitted over the upper engine to reduce engine generated noise.
The engine utilises the following features:
•
Electronic Unit Injectors (EUI’s) controlled by an Engine Management System for precise fuel delivery under
all prevailing operating conditions.
•
Turbocharging which delivers compressed air to the combustion chambers via an intercooler for improved
power output.
•
Fuel Cooler
•
Oil Cooler
•
Centrifuge Oil Filter
•
Hydraulic Lash Adjusters with independent finger followers
