Why do gasoline engines not compress fuel to auto ignition? Gasoline is designed to readily evaporate into air and not to ignite during compression in the engine cylinder. Air is compressed in the diesel engine cylinder before the fuel is injected so there can be no preignition.
Why is petrol not a compression ignition? Gasoline can’t be used because it needs compression ration of 8-10 and CI engines are designed to have compression ration above 18. So when gasoline is fed, it will automatically burn and hence create a blast way below the TDC of crank.
How much compression does it take to ignite gasoline? The pressure is so great (16:1 or 234 psi) that the temperature becomes high enough to ignite the fuel without a spark plug. Compression brings fuel particles together in an engine, heating them, and giving them the opportunity to burn more rapidly.
Why CI engine is more efficient than SI engine? With a higher compression ratio in CI engines as compared to SI engines, CI engines have a higher thermodynamic efficiency since more work is done with each expansion stroke.

What engine oil to use in summer?
As a general rule, you’ll get the best protection in the summer when you use a slightly thicker grade of oil, such as a 10W30 instead of a 5W30. Engines need a thicker oil in the summer months because of the summer heat and its effects on thinning the oil out.
