In an IC engine, combustion was found to proceed during the expansion
stroke also. The reason could be :
आईसी इंजन में, विस्तार स्ट्रोक के दौरान भी दहन होता पाया गया। इसका कारण यह हो सकता है:
Rich mixture with ignition advance
High calorific value of the fuel
Weak mixture without ignition advance
Weak mixture with ignition advance
Rich mixture with ignition advance
●In an IC engine, the reason behind
the combustion to proceed during the expansion stroke also, is the rich mixture
with ignition advance.
●When ignition is advanced, too much
of gas burns while the piston is rising and when the mixture is too rich then the
combustion takes place in some part of expansion also.
Hence, the correct option is (A).
