Exhaust flexible pipe
All petrol vehicles are fitted with a stainless steel exhaust system consisting of:
catalytic converter(s)
front pipe
muffler inlet pipe
front muffler assembly
muffler and tailpipe assembly
The exhaust system is designed to meet the rising standards of vehicle emissions, complying with LEV (USA) and stage three (Europe)
emission legislation; effective from January 2001.
The exhaust system is supported at the front by the two catalytic converters which are retained directly to the exhaust manifolds by studs
and nuts. The remainder of the exhaust system is supported by four rubber hanger isolators. On 2.0L and diesel vehicles there are three
attached to the front muffler assembly and one attached to the rear muffler. On 2.5L and 3.0L vehicles there is one attached to the front
muffler and three attached to the rear muffler and tail pipe assembly.
A flexible coupling, which is part of the front muffler, is fitted to isolate the exhaust system from engine movement and vibration.
For 2.5L and 3.0L vehicles the rear exhaust muffler and tail pipe assembly is manufactured in one section which consists of a 'Y' pipe joined
to the two rear muffler and tail pipes. A service fix is provided for replacement of the rear mufflers and tail pipes. For 2.0L and diesel
vehicles there is a single rear muffler assembly which is attached to the left-hand side of the vehicle.
Three Way Catalytic Converters
The catalytic converters each contain two bricks coated with palladium/rhodium. These elements are utilized to control the emissions of
hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx) from the engine.
Oxidation Catalytic Converter
The catalytic converter contains a brick coated with platinum. This element is utilized to control the emissions of hydrocarbons (HC), carbon
monoxide (CO) and particles of matter from the engine.
Diesel Particulate Filter
The Diesel Particulate Filter (DPF) system reduces diesel particulate emissions to negligible levels (0.005 g/km) to meet current local
European City clear air requirements.
The particulate emissions are the black fumes emitted from the diesel engine under certain load conditions. The emissions are a complex
mixture of solid and liquid components with the majority of the particulates being carbon micro-spheres on which hydrocarbons from the
engine's fuel and lubricant condense.
The DPF filter system consists of the following components:
