Abstract

A swash plate type opposed-piston two-stroke external-combustion engine, comprising a cylinder block, a main shaft hole is opened in the middle of the cylinder block, six axially penetrating cylinders are evenly arranged on the outer periphery of the main shaft hole, and two front and rear cylinders are arranged opposite to each other in the cylinder. There are two pistons, and the front and rear ends of the cylinder are equipped with compressed air rotary valves, and the middle of the cylinder is equipped with a working rotary air valve. Among the twelve pistons, nine pistons take in air from the environment through the compressed air rotary valves and perform one-stage compression. To the gas storage branch pipe, the three pistons take in air from the gas storage branch pipe through the compressed air rotary valve and perform secondary compression to the combustion chamber. Among the six cylinders, three cylinders perform primary work, and three cylinders perform secondary work. The first-stage work cylinder is the cylinder where the piston of the second-stage compression is located, and the second-stage work cylinder is the cylinder where the two pistons before and after the first-stage compression are all performed. This design improves the utilization rate of heat energy.

Description

technical field

[0001] The invention relates to a piston engine, in particular to a swash plate type opposed piston two-stroke external combustion engine, which is mainly suitable for improving the utilization rate of heat energy. Background technique

[0002] At present, the internal combustion engine is widely used in various fields, and its thermal efficiency seems to have reached its peak. It has not been greatly improved for many years. According to the analysis, the heat loss is mainly due to the following points:

[0003] 1. The exhaust heat has lost 35% to 50%. When the exhaust valve is opened, there is still an air pressure of about 1MPa in the cylinder. The air stroke causes greater resistance, and the gain outweighs the gain. Now the multi-valve technology is used to reduce the air resistance, which is effective, but still unsatisfactory;

[0004] 2. Cooling system, the vortex flow of high-temperature gas in the combustion chamber helps to complete the combustion...
