Abstract

The invention relates to a cylinder cam engine without a bent axle. The cylinder cam engine without the bent axle mainly comprises an engine body set, piston connecting rod sets, a rotating cam, a gas distribution cam, a gas distribution planetary gear train, a gas distribution system, a bearing packing, a bolt set and the like. The cylinder cam engine without the bent axle is characterized in that when the engine works, the upper piston connecting rod set and the lower piston connecting rod set make reciprocating motion in a cylinder tank body; a roller 17 and a roller 28 roll in an upper rotating cam groove 10.1 and a lower rotating cam groove 10.2 respectively to enable the rotating cam to rotate; an output shaft is driven to rotate, and as power output, the output shaft transmits power to the gas distribution cam through a planet gear; the gas distribution cam rotates to trigger a valve ejection rod to act; and a valve rocker arm set acts to enable a gas spring set to act to achieve regular gas distribution of all cylinders. The cylinder cam engine without the bent axle is excellent in reliability, the single-cylinder acting output shaft is rotated by 180 degrees, the overall structure is simple, the size is small, and the efficiency is high.

Description

technical field [0001] The invention relates to a cylindrical cam engine without a crankshaft, which is suitable for the technical field of internal combustion engines. Background technique [0002] The engines on the automobile market mainly include crankshaft-connecting rod type, rotary engine and other types of engines. The most widely used is the crankshaft-connecting rod type internal combustion engine. The requirements for ignition timing and valve timing are quite strict, and the traditional engine converts the reciprocating linear motion of the piston into the rotary motion of the crankshaft to output power. The manufacturing process of the crankshaft is complicated and the processing difficulty is high. These factors not only affect the manufacturing cost of the traditional engine, but also affect the trend of the miniaturized design of the engine. The invention patent application for "Single Cam Set Without Crankshaft Engine" co-opened by the Chinese Patent Office...
