1.4 PURE PLANT OIL (PPO)
SVO (Straight Vegetable Oil) or Pure Plant Oil is a fuel that
can be extracted from a number of agricultural products, of
which rape seed is the most commonly used. In contrast to
biodiesel, PPO fuels do not undergo esterification. As a
result, they remain very (highly) viscous, even at normal and
low temperatures, so that a preheated fuel supply system is
essential to improve cold starts or to even make them possi-
ble. Engines will run at the operating temperature, but the
use of the fuel results in an increase in emissions, deposits
in combustion chambers and a reduction in performance and
the useful life of fuel injection equipment. The use of PPO is
not permitted as a fuel in combustion engines, because the
aspects mentioned above lead to unacceptable damage and
(reduced) expectations with regard to the useful life of the
engine.
1.5 CITY DIESEL
Just like the current fuel for daily use, city diesel is refined
from fossil fuel, but the composition is improved during the
refining process. A lower sulphur content and a lower aro-
matics content are common for all city diesel fuels, which,
together with other possible chemical changes during the
refining process, result in almost sulphur-free emissions with
less particulate matter (PM) and a lower nitrogen oxide
(NOx) content. City diesel is also known as ULSD (Ultra Low
Sulphur Diesel).
