The valves of an ic engine are made to open and close slowly to ______

1.	The valves of an ic engine are made to open and close slowly to _________(a) Increase the engine efficiency(b) Decrease the fuel consumption(c) Allow engine to cool in the meantime(d) Provide silent operation under high speed conditionsThis question was addressed to me in unit test.This question is from Development of IC Engines topic in division Internal Combustion Engines of Automobile Engineering
Answer» CORRECT option is (d) Provide SILENT operation under high speed conditions Best explanation: The VALVES are made to open and close SLOWLY to provide silent operation under high speed conditions.
