ABSTRACT

 

In this paper the experimental studies on controlling piston slap noise of standard engine of Hero Honda Splendour has been conducted. It is observed that the noise reduction achieved by reducing the clearance in an engine, between piston and cylinder, does not permit reduction in piston clearances, as because danger of seizure may occur without using positive oil cooling of the piston. It is advisable and better to consider noise control measures at the design stage itself rather than after the product is manufactured. The present paper describes one example of noise-reducing design. An experiment was conducted to investigate piston slap noise in Hero Honda Splendor plus and low noise was obtained by reducing the clearance between piston and cylinder.
