Yamaha to introduce DiASil cylinder in India

Parallel to a slew of launches, Yamaha Motor India is aiming to demonstrate its technological prowess with the launch of DiASil Cylinder in the Indian market. Yamaha “DiASil Cylinder” is used on the new 150cc YZF-R15 which was unveiled at Auto Expo 2008 and will be released in the market later this year.

Developed in 2002 by Yamaha Motor Co., Ltd, Yamaha “DiASil Cylinder” is an all-aluminum die-cast cylinder with 60% better cooling performance and 30% cheaper production cost than a conventional cylinder (*1). Yamaha “DiASil Cylinder” (*2), is the world’s first all-aluminum die-cast cylinder and it achieves cooling performance equivalent to that of a nickel-plated cylinder, which is currently recognized as the best in the industry, but at a significantly lower production cost than a nickel-plated cylinder.

DiASil", an abbreviation for "Die-casting Aluminum-Silicon", is a technology which brings together an ideal combination of material, manufacturing technology and environmental friendliness. The material used is a 20% silicon content aluminum alloy, the manufacturing technology is the Yamaha CF Aluminum Die-cast Technology (*3), which enables the production of an all-aluminum die-cast cylinder. It is Yamaha’s exclusive CF Aluminum Die-cast Technology that enables the mass production of a die-cast cylinder made completely of 20% silicon content aluminum alloy, something that could not be done with conventional die casting methods.

According to Mr. Sanjay Tripathi, Head of Dept- Product Planning & Strategy, “Conventional engine cylinders have a steel liner to reduce the friction resulting from the piston's movement. The "DiASil" cylinder is made by the exclusive Yamaha Aluminum Controlled Forging (CF) technology. Because the "DiASil" Cylinder is all aluminum, it has excellent heat dissipation qualities and reduces engine weight at the same time. In comparison to cast steel liner type aluminum cylinders, the DiASil cylinder has 60% better cooling performance at 30% lower manufacturing cost and enables 30% lighter design which results in better power to weight ratio besides excellent recyclability”.

“Considering the environment-friendly nature of aluminum, we have made aluminum technologies part of our core technology and actively increasing the use of aluminum in our products. Our CF Aluminum Die-cast Technology enables the mass production of die-cast aluminum parts that are both thinner and larger than was possible in the past. This same technology has been applied to the manufacture of engine parts. This is also a technology that can be easily transferred to overseas Yamaha manufacturing bases. Yamaha also plans to apply to new areas automobile and outboard motor engine parts”, he added.

This next-generation technology promises to contribute to improved function and product quality for the majority of Asian market motorcycles and automobiles that presently use conventional pistons with cast steel liners.
