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...

AI Technical Summary

Problems solved by technology

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 large number of nitrogen oxides and sulfides in the combustion products, these substances are harmful to clean emissions and environmental protection is fatal

At the same time, during the operation of the generator set, due to the above-mentioned defects of the internal combustion engine, the operating state of the generator is very unstable. Therefore, a bulky transmission device is added to stabilize the dynamic performance of the internal combustion engine, and considering the requirements for heat dissipation of the internal combustion engine and system control, It also needs to add accessories, such as cooling system, waste circulation system, internal combustion engine starting system, generator current conditioning system and generator set comprehensive matching system, these systems are large and complex, and the cost is high

From the perspective of energy efficiency, the chemical energy of the fuel is transferred to the rotational mechanical energy of the crankshaft of the internal combustion engine, and then transferred to the rotational mechanical energy of the generator power by the transmission device, and finally converted into electrical energy output. The entire energy chain is long, and due to heat transfer, heat dissipation, exhaust emissions and Energy loss such as mechanical friction, the energy transfer efficiency of the whole system is low, the cost is high, and precious oil resources are wasted
