Aisin
Starts Business with Ford Australia, Supplying VVT, OCV and Oil Pumps
(December 12, 2002) |
Aisin
Seiki (President: Kanshiro Toyoda; Headquarters: Kariya, Aichi, Japan) received
orders from Ford Australia for the first time for engine related products; variable
valve timing (VVT), oil control valve (OCV), and oil pumps, and began deliveries
in September. VVT is effective in improving fuel efficiency and reducing exhaust
emissions, and OCV operates the hydraulic control for VVT. These products have
been designed for the new engine developed by Ford Australia, and will be mounted
on the "Falcon".
VVT is a control device that optimizes the timing for opening or closing the valve
for air intake or exhaust according to engine RPM. It is also effective in improving
fuel efficiency as well as reducing exhaust emissions. An increasing number of
cars have been equipped with VVT to meet environmental requirements.
Aisin aims to place VVT as the third pillar in its primary sales of engine related
products of oil pumps and water pumps, which has the largest market share in the
world. The number of inquiries Aisin receives is large. And the company is planning
to increase annual production because the number of companies in the U.S., Europe,
and Japan that will use the VVT is expected to increase in the future.
"We will promote this product to the Big 3 and European car manufacturers," said
Aisin.

Variable
Valve Timing (VVT) |
| 2.Characteristics: |
Vane
system
VVT does not use the traditional piston and gear (helical gear) design.
Instead, oil pressure is applied against a thin vane to cause rotation.
- The vane
design can integrate the sprockets and housings, and in turn simplifies and downsizes
the structure and lowers the cost.
- The vane
design allows the VVT to be installed on the exhaust side. This is the first-ever
design of this type.
<Reference> Effect
of mounting VVT
Reduction of fuel consumption by 4.8%, reduction of Nox by 40% in emission, and
output increase by 10%
* Above values are the results of the comparison with a vehicle not equipped with
the VVT, the evaluation conducted by Aisin. |
