Question
In a diesel engine the high temperature needed to
ignite the fuel is achieved by –Solution
Diesel engines use the heat of compressed air to ignite the fuel (intakes air, compresses it, then injects fuel). Diesel engines need high compression ratios to generate the high temperatures required for fuel auto ignition.
