Yamaha going to launch DiASil cylinder in India

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.

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.

Mr. Sanjay Tripathi, Head of Dept- Product Planning & Strategy Said in a statement that “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”. This is also a technology that can be easily transferred to overseas Yamaha manufacturing bases.
