Description

technical field

[0001] A single-piston linear power generation engine of the invention belongs to the technical field of internal combustion generators. Background technique

[0002] Existing internal combustion generator sets usually use a combination of a traditional internal combustion engine and a generator. Due to its inherent structural and principle limitations, traditional internal combustion engines have inherent deficiencies in efficiency, energy and environmental issues. For example, the inertial force and unbalance brought by the crank linkage mechanism greatly reduce the efficiency of mechanical and energy conversion and transmission, which inevitably causes severe vibration of the whole machine and causes noise, which is then transmitted through the interior of the car. Noise pollution caused discomfort to drivers and occupants; due to the limitation of combustion conditions, insufficient fuel combustion, coupled with the impact of fuel pollutants, there are a...
