Abstract

The invention relates to a new loop optimization method of a non-supercharged high-efficiency energy-saving internal-combustion engine, aiming at leading the expansion ratio in the polytropic process of working substance of the internal-combustion engine to be higher than the compression ratio thereof. The method overcomes the defect that the expansion ratio of high temperature and high pressure gas of the internal-combustion engine is equal to the compression ratio of low temperature and low pressure air. The method ensures the high temperature and high pressure gas is most fully expanded in an air cylinder, thus reducing the exhaust loss. Meanwhile, a mathematical analytic method is adopted to determine the corresponding optimum compression ratio when circulating power is maximum value, thus greatly improving the specific work (that is the work done by unit mass working substance) of working substance and reducing fuel consumption rate.

Description

technical field

[0001] The invention relates to the field of high-efficiency energy-saving cycle optimization design of internal combustion engines, in particular to a new cycle optimization method for non-supercharged high-efficiency energy-saving internal combustion engines. Background technique

[0002] The internal combustion engine cycle generally has four strokes: intake stroke, compression stroke, combustion and expansion power stroke, and exhaust stroke. Their common disadvantage is that the heat removal process is carried out in a state close to constant volume. Since the gas is not fully expanded in the cylinder, the discharged gas still has a certain pressure and high temperature, resulting in a large energy loss. It is one of the important reasons why the energy utilization rate of the non-supercharged internal combustion engine is not high. The use of technologies such as exhaust gas turbocharging can obviously increase the power of the engine and improve the e...
