The main ways of heat engine energy loss are: internal energy of exhaust gas, mechanical loss and heat dissipation loss. Ways to improve heat engine efficiency and reduce heat engine energy loss: 1. Fully burn the fuel and minimize various heat losses; 2. Maintain good lubrication between parts and reduce friction; 3. Reduce mechanical heat dissipation and exhaust gas taking away heat. .
#A heat engine is a machine that uses internal energy to do work and converts internal energy into mechanical energy.
Types of heat engines: steam engines, internal combustion engines (gasoline engines and diesel engines), steam turbines, jet engines, etc.
Heat engines always lose energy during their working process. The main way of heat engine energy loss is: exhaust gas internal energy , heat dissipation loss, machine loss.
Ways to improve the efficiency of thermal engines:
① Fully burn the fuel and minimize various heat losses;
② Maintain good lubrication between parts to reduce friction .
③Reduce mechanical heat dissipation and exhaust gas taking away heat
Among various energy losses in heat engines, exhaust gas takes away the most energy. Trying to use the energy of exhaust gas is important to improve fuel utilization. measure.
