Actually the efficiency of carnot engine is increased by decreasing the lower temp not increasing higher temperature.

I think efficiency is increased by increasing the lower temperature and decreasing the higher temperature.

The more effective way of increasing efficiency of Carnot engine is to Decrease lower temperature.

@Vivek.
Please see the T-S diagram of Carnot cycle.
According to you that heat transfer during the cycle will be reduced as well as efficiency will be reduced.
Your statement is correct for Reversed Carnot cycle where we need to reduced heat transfer to achieve greater efficiency.

The efficiency of Carnot cycle = 1-T2(LOWER TEMP)/T1(HIGHER TEMP).
So from this formula, you can use as respective terms.

Efficiency of carnot engine is increased by decreasing the lower temp and increasing higher temperature but more effects on efficiency of cannot cycle by decreasing temperature as compare increase temperature of cannot engine.

The Efficiency of Carnot cycle is increased by 'decreasing the lower temperature', hopefully, this helps you.

Actually efficiency of Carnot cycle depends upon the temperature of the sink so if temperature of the sink decrease efficiency increase or efficiency increase by increase temperature of source.
