What is the need for a high compression ratio? Today every machine is expected to give higher efficiency. When we talk about the petrol engine and diesel engine whose thermal efficiency is directly related to the ‘compression ratio’. That means if we want to achieve higher thermal performance in terms of efficiency, we should provide … Read more
