The devices for curtailing diesel fuel en-
gine emissions are the following:
❒oxidising catalytic converter;
❒exhaust gas recirculation system
(E.G.R.);
❒ diesel particulate filter (DPF).
PROTECTING THE
ENVIRONMENT
The devices for curtailing petrol engine
emissions are the following:
❒ three-way catalytic converter;
❒ Lambda sensor;
❒ fuel evaporation system.
In addition, do not let the engine run,
even for a test, with one or more spark
plugs disconnected.
During normal service
the diesel particulate
filter (DPF) reaches high tem-
peratures. Do not therefore
park the car over inflammable
materials (grass, dry leaves,
pine needles, etc.): fire hazard.
