Calculate the efficiency of a petrol engine if the compression ratio is 9. y=1.4. If the power of the engine is 30 kW, what is its input power ?

Text Solution

Verified by Experts

`eta =1 - (1// rho ) 6( gamma - 1) , rho = 9, gaamma = 1. 4` Solving `eta = 0. 5846= 58.46%`
(Input = Output `//eta = 30 xx 10 ^(3) //0.5846 = 5.13 xx 10 ^(4) W)`

The efficiency of a heat engine is defined as the ratio of the mechanical work done by the engine in one cycle to the heat absorbed from the high temperature source . eta = (W)/(Q_(1)) = (Q_(1) - Q_(2))/(Q_(1)) Cornot devised an ideal engine which is based on a reversible cycle of four operations in succession: isothermal expansion , adiabatic expansion. isothermal compression and adiabatic compression. For carnot cycle (Q_(1))/(T_(1)) = (Q_(2))/(T_(2)) . Thus eta = (Q_(1) - Q_(2))/(Q_(1)) = (T_(1) - T_(2))/(T_(1)) According to carnot theorem "No irreversible engine can have efficiency greater than carnot reversible engine working between same hot and cold reservoirs". Efficiency of a carnot's cycle change from (1)/(6) to (1)/(3) when source temperature is raised by 100K . The temperature of the sink is-
