For the off-road industry, BASF Catalysts
will offer diesel oxidation catalysts
(DOCs), catalyzed
soot filters, partial
DOCs and selective
catalytic reduction
(SCR) catalysts, using its experience
with these products in
the automotive and
truck industry.
As BASF steps into the off-road emissions arena, it’s arming itself with a full toolbox of experience and products to handle
the array of equipment types, duty cycles
and applications this market brings. Unlike
on-highway vehicles where so much of the
emissions regulations up until now have
been focused, off-road equipment presents a whole new set of challenges.
Every day, more than 3 million passengers travel along Hong Kong’s busy transit system.
Hong Kong is a city affected with
street-level air pollution from the
increasing number of vehicles in the
urban area and the miles driven. The
Hong Kong government has instituted
a number of initiatives to combat the
problem, including a diesel retrofit program aimed at reducing emissions
from buses, trucks and vans.
One of the latest measures of the
program has been the installation of
diesel particulate filters (DPFs) on a
fleet of Euro 2 and 3 buses, bringing
them to the Euro 5 standard for PM
emissions. The city will retrofit 2300
buses in the Kowloon Motor Bus Co.
Ltd., The New World First Bus Services
Ltd., Citybus Co. Ltd. and New Lantao
Bus Co. Ltd. companies’ fleets.
The fleets consist of Volvo Super
Olympian and Olympian buses powered by 9. 6 L Volvo D10A diesel

“With a Class 8 truck, you know what
the cycles are going to be,” said Ardite.
“It’s going to be on the highway. There’s
going to be some idle time. You just work
within those confines. When it comes to
off-road, it might be a small bulldozer to
a huge crane, and there are hundreds of
applications. You really need to design a
catalyst and work with the engine suppli-
er and vehicle supplier to refine those
things. You’ll have the same toolbox of
catalysts but the opportunity exists to
work with the engine companies to real-
ly apply it differently.”
The off-road industry will see a
stream of diesel oxidation catalysts
(DOCs), catalyzed soot filters, partial
DOCs, and selective catalytic reduction
(SCR) catalysts from BASF. While
these products have been optimized
over time for the automotive and truck
industry, for off-road they will require
some additional tweaking.
Hong Kong’s transit system will install BASF DPX Max diesel particulate filters (shown here) on 2300
buses, bringing the fleet of Euro 2
and 3 buses to the Euro 5 standard
for PM emissions.
engines and Dennis Trident and Dragon
buses with 10. 8 L Cummins M- 11 diesels.
For the retrofit, the buses will be
equipped with BASF’s DPX Max filters.
The DPX Max DPFs are designed to
trap particulates in the exhaust, using a
patented catalyst to continuously burn
soot during normal diesel operating
exhaust temperatures. By installing the
filter, the Euro 2 engines will meet Euro
5 standards, reducing PM emissions
more than 80%, BASF said.
