PERTH, Australia, Nov. 7 /PRNewswire-FirstCall/ -- Orbital
Corporation Limited is pleased to announce two significant contracts
for its fuel injection technology in both 2-stroke and 4-stroke
engine applications. The contracts relate to Orbital's spark ignited
combustion technology for heavy fuels, which are kerosene based fuels
such as diesel.

In the first development, Orbital Corporation has finalised a
contract for the development of the first production application of
its spark ignited heavy fuel technology for a 4-stroke engine. This
contract is with a major North American original equipment
manufacturer (OEM) to provide the OEM with engineering services in
relation to Orbital's proprietary direct injection technology for a
land-based vehicle application operating on heavy fuel.

The contract is expected to generate revenue in excess of A$2 million
over a period of 18 months, with a target start of production in 2007.

Orbital Chief Executive Officer Rod Houston said the contract was
significant for Orbital because it was in line with our strategy to
grow Orbital's technology on 4-stroke engine platforms.

In the second development, Orbital has been engaged by German engine
manufacturer Goebler-Hirth Motoren (Hirth) on a significant
engineering program for the preliminary development of a new 2-stroke
engine to operate on heavy fuel for an Unmanned Aerial Vehicle
application using Orbital's air- assist Direct Injection technology.

Hirth entered into a license arrangement with Orbital in April 2005
to use Orbital's air-assist DI on a range of 2-stroke engines which
can operate on heavy fuel.

Mr Houston said the two contracts underlined the strengths of the
Orbital Combustion Process technology, (OCP) the collective name for
the company's unique air-assisted, low-pressure direct fuel
injection, combustion and engine management system.

"These programs are confirmation of some of our unique capabilities
with OCP, and illustrate the benefits of our targeted R&D efforts
over the last 18 months to develop new applications for our
technology," said Mr Houston.

"These new markets are important for the growth of our engineering
services, future royalty streams and the sale of Synerject
components."
