<h1>Self-Ignition Temperature of Diesel vs Petrol – SSC JE 2014 (Morning)</h1><h4>Question:</h4><h5>
Self-ignition temperature of diesel as compared to petrol:</h5><h5>(a) is higher / उच्चतर होता है 
(b) is lower / निम्नतर होता है  
(c) is same / समान रहता है 
(d) varies considerably / काफी परिवर्तन रहता है</h5><hr data-start="369" data-end="372"><h5>Correct Answer: (b) is lower</h5><h5>Video Solutions: <a href="https://www.youtube.com/watch?v=lxx0j137Mks&list=PLjQMEOXj4i1_I4Lg19iJ7L43an_XWUWg7&index=8" target="_blank">Click here</a></h5><hr data-start="416" data-end="419"><h4>Explanation:</h4><ul data-start="444" data-end="927">
<li data-start="444" data-end="590">
Self-Ignition Temperature (SIT) is the temperature at which a fuel spontaneously ignites without an external ignition source like a spark.
</li>
<li data-start="591" data-end="622">
Diesel: SIT ≈ 210°C
</li>
<li data-start="623" data-end="658">
Petrol: SIT ≈ 247–280°C
</li>
<li data-start="659" data-end="835">
Since diesel has a lower self-ignition temperature, it can ignite just by the heat generated during compression — hence diesel engines use compression ignition.
</li>
<li data-start="836" data-end="927">
Petrol requires a higher temperature to ignite, so petrol engines use spark ignition.
</li>
</ul><hr data-start="929" data-end="932"><h4>Key Points for Exams:</h4>

<ul data-start="960" data-end="1097">
<li data-start="960" data-end="987">
Diesel SIT < Petrol SIT
</li>
<li data-start="988" data-end="1044">
Diesel engine → Compression Ignition (no spark plug)
</li>
<li data-start="1045" data-end="1097">
Petrol engine → Spark Ignition (uses spark plug)</li></ul>
