| Collier Technologies (CTI) claims that its
new low emissions 11 Litre "city engine" beats the forthcoming
emissions standards due to be introduced in the US in 2007. The engine
has documented NOx emission levels well below the .2 gms/hp-hr standard
set for heavy-duty engines beginning in 2007, at .08gms/hp-hr across the
engine's power range. This is without any exhaust catalytic treatment.
The city engine is designed and specifically targeted for transit and
heavy duty services, operating on a CTI developed mixture of 30 per cent
(by volume) mixture of hydrogen, with the balance of natural gas (HCNG).
CTI president, Jerry Jones, said, "We are pleased to be able to offer
these extremely low emissions on an engine that will deliver 300hp (223
kW) with about 900 ft lb (1,220 Nm) of torque. We are also pleased with
the overall fuel savings and increased engine life expectancies due to
operating in a lean burn mode at lower than normal exhaust temperatures."
CTI is in partnership with Daewoo Heavy Industries and Hess Microgen to
produce the engines in the US . The engine will undergo California Air
Resources Board (CARB) certification over the next year, while being put
in service in several anticipated demonstration platforms. Fuelling infrastructure
for the buses is available through partner, Trillium USA.
CTI is a 10-year-old technology development and licensing company based
in Reno , Nevada , that specialises in low-emission hydrogen applications
for internal combustion engines. CTI technology is applied to stationary
power and multiple transportation applications. An 8 litre HCNG engine
is also under development.
