Embodiment Construction

[0019] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the first embodiment of the invention is a two-stroke diesel or gasoline engine. It has a piston cylinder arrangement group A, several connecting rods 9, and a crankshaft 11. The piston and cylinder configuration group A has a cylinder 1 and a pair of working pistons 3 arranged on top of each other in the cylinder, and the cylinder has an exhaust hole 2 and an air inlet 13 . The crankshaft 11 is a single crankshaft, and the piston and cylinder configuration groups A are arranged in parallel in pairs (that is, the axes of the cylinders are parallel to each other). The piston and cylinder configuration groups can be arranged in one pair, two pairs or multiple pairs, and the pairs are not necessarily parallel to each other, and can be set at different angles according to the needs of the position (only one pair is shown in the figure). The size of each pair of piston-cylinder configuration groups is the sam...

Abstract

The utility model relates to an internal combustion engine with two cylinders working at the same time and a single crankshaft opposed to the top piston, which has a piston cylinder arrangement group, a connecting rod and a crankshaft. The crankshaft is a single crankshaft, and the pistons and cylinders are arranged in parallel in pairs. It is characterized in that the connecting rod journals of the crankshafts connected to the corresponding connecting rods connected to each cross bar in each pair of piston cylinder configuration groups are arranged on a crank throw or several independent connecting rod journals. On crankshafts whose axes are collinear, the included angle between the two planes formed by the axes of the connecting rod journals corresponding to the two cross bars and the axis of the main journal of the crankshaft is 150°-180°. It further simplifies the structure of the internal combustion engine with top pistons, works reliably, reduces the lateral force of the piston and the wear of the main journal of the crankshaft, reduces the vibration, improves its mechanical efficiency and torque, and reduces the manufacturing cost.

Description

technical field [0001] The invention relates to a piston reciprocating internal combustion engine. Background technique [0002] The thermal efficiency of existing internal combustion engine is very low, only has about 30-50%, is used to improve the thermal efficiency of internal combustion engine and adopts the technology of top piston engine a lot at present, and there are many literature reports about this technical aspect, for example CN86108669A discloses a cylinderless It is a double-piston multi-cylinder conjugate diesel engine. This invention designs a parallel arrangement of at least four cylinders. Each cylinder is equipped with two pistons that move in opposite directions. The intake and exhaust valves are respectively installed on the two pistons. , in each cylinder, the combustion chamber is surrounded by the cylinder liner and two pistons, and each piston on the same side at both ends of the cylinder is fixedly connected to the horizontal ...
