Web– SI engine peak heat flux ~ 1-3 MW/m2 – Diesel engine peak heat flux ~ 10 MW/m2 • For SI engine at part load, a reduction in heat losses by 10% results in an improvement in fuel consumption by 3% – Effect substantially less at high load 15 SI Engine Heat Transfer • … WebCarnot efficiency depends on high temperature and low temperatures between which the heat engine operates. We are given both temperatures. However, the temperatures need to be converted to Kelvin: T h o t = 540 o C + 273 = 813 K T c o l d = 20 o C + 273 = 293 K η = [ 1 − T c o l d T h o t] × 100 % η = [ 1 − 293 K 813 K] × 100 % = 64 % Practice
