Abstract

The invention provides a two-stroke engine. A piston is arranged between two air cylinder guide rails, piston grooves are formed in the air cylinder guide rails, and the piston slides along the air cylinder guide rails. An air cylinder is arranged in the piston and fixed to the air cylinder guide rails through openings of the piston grooves, and the air cylinder is matched with the air cylinder guide rails to divide an inner cavity of the piston into two independently sealed air chambers; the two opposite sides, located on the two air chambers, of the air cylinder are respectively provided with a groove, an air inlet channel, an ignition placement channel, an air inlet valve placement channel, an air exhaust channel and an exhaust valve placement channel are arranged between the side walls of the grooves and the air cylinder guide rails, an air inlet valve is arranged in the air inlet valve placement channel, an ignition device is arranged in the ignition placement channel, and an exhaust valve is arranged in the exhaust valve placement channel. The power of the working volume of the air cylinder is higher, air inlet is full, exhaust is complete, and fuel is saved; ignition efficiency is high, the spreading speed of sparks is high, lubricating and cooling are easier to conduct, machine oil consumption is small, mechanical loads and thermal loads are small, and the service life of the engine is longer.

Description

technical field [0001] The invention belongs to the field of engine devices, in particular to a two-stroke engine. Background technique [0002] The main problems with traditional two-stroke engines are: [0003] (1) The ventilation time is short, and the process of intake and exhaust is carried out at the same time, which leads to the easy mixing of fresh air and exhaust gas, and the large coefficient of residual exhaust gas, resulting in a decrease in economy and an increase in exhaust gas emissions. [0004] (2) Due to frequent work, large mechanical load and thermal load, and difficult lubrication, the life of the two-stroke engine is shortened. [0005] (3) Because the height dimension of the exhaust port accounts for 20-40% of the piston stroke, the actual working displacement of the traditional two-stroke engine is only 60-80% of the nominal displacement. Contents of the invention [0006] The object of the present invention is to provide a two-stroke engine, aimi...
