Environmental problems have come under close scrutiny throughout
the world. Automotive, truck and other vehicle manufacturers have responded by
concentrating their efforts on developing and introducing a variety of environmentally
friendly vehicles.
The heart of any vehicle is its engine. Engines for environmentally friendly
vehicles operate under conditions that are continually more demanding and require
components and parts that embody the highest level of technology.
Riken manufactures piston rings that operate as critical, functional parts in
an internal combustion engine. Today Riken is helping its vehicle manufacturer
customers develop environmentally friendly vehicles by providing a variety of
piston rings that are designed and produced with advanced engineering and technology.
We will continue to work closely with our engine customers and are committed
to further advancements in ring design and manufacturing technologies to ensure
that the right parts are available to serve the engines of the future.
