Increasing the compression ratio in SI engines _______ the detonation
tendency.
एसआई इंजनों में संपीड़न अनुपात बढ़ाने से डेटोनेशन की प्रवृत्ति _______ हो जाती है।
decreases
increases
first increases and then decreases
does not affect
increases
Increasing the compression ratio in SI
engines increases the detonation tendency.
Hence, the correct option is (B).
&Key Points:-
In CI engine,
knocking tendency decreaseswith increasein compression ratio.
If compression ratio is low in CI engine, there will not be
enough temperature generation for ignition of the fuel air mixture.
