The advantage of this internal combustion engine:

The compression ratio of traditional reciprocating IC engine and triangle rotator internal combustion engine and expansion ratio are equal, and this leads The also very high pressure of tail gas of traditional internal combustion engine and temperature are caused and also substantial portion of energy is not obtained by The therefore thermal efficiency is low and oil consumption is high, at present application triangle rotator internal combustion engine because compression ratio is little and working stroke is short with the time Lead to fuel can not fully work by combustion so the lower oil consumption of the thermal efficiency is higher.This internal combustion engine can be by changing air inlet 12 Change compression to the distance of second seal 16 with the ratio expanding so that the expansion ratio of gas is more than the compression ratio of gas And the thermal efficiency improving internal combustion engine (is equivalent to tail gas on the basis of traditional internal combustion engine and is also continuing acting, this sample internal combustion The temperature of tail gas than traditional internal combustion engine for the pressure and temperature of the tail gas of machine and pressure are low), because this internal combustion engine also has Working stroke length is so the thermal efficiency of this internal combustion engine is higher.

This internal combustion engine does not have reciprocating parts, and all moving components are all to make pure circle week rotary motion, institute The phenomenon more do not shaken operationally is not vibrated with this internal combustion engine, and traditional internal combustion engine is because have piston, bent axle, company Bar etc. in a large number reciprocating part so there is not eliminable high vibration and shake during work.Even in three-apexed rotor Combustion engine is because piston is not pure circular motion vibration and shake are also not eliminable.

This internal combustion engine does not have valve match mechanism of bent axle, connecting rod, piston ring and complexity etc. so the knot of this internal combustion engine The more simple volume of structure is less, and noise in operating is lower, and processing and manufacturing is more convenient, and cost is lower.

During the operating of the parts such as traditional I. C. engine crankshaft, connecting rod and piston extruding each other very big so needing big Can run well, even if so using substantial amounts of profit between the lubricating oil of amount and each parts of lubricating system guarantee of complexity The bent axle of oil lubrication reciprocating IC engine, connecting rod, piston, piston ring particularly cylinder block also can heavy wear and lead to leak Gas and service life greatly shorten.And this internal combustion engine only has between gear and needs to lubricate, and between piston, cylinder body and sealing member Neither need similar piston ring etc sealing ring and also each other only contact not extruding thus almost do not rub and More preferably, so this internal combustion engine seal is more preferably, abrasion is less, and because the energy of friction loss is less, service life is more for sealing effectiveness Long.

Triangle rotator internal combustion engine is because irregularly the leading to its sealing effectiveness difference and manufacture and keep in repair of cylinder block and piston Difficult and high cost.

In sum, this internal combustion engine is compared with traditional reciprocating IC engine and triangle rotator internal combustion engine, three it The work efficiency of middle internal combustion engine is bigger, and the thermal efficiency is higher, and oil consumption is minimum, and structure is the simplest, operating is the fastest the most steadily, noise Little, friction is minimum, sealing effectiveness is best, mechanical power loss is minimum, and cost is minimum, and maintenance is more convenient, and it is excellent that service life is the longest etc. Point.
