Two-in-one cylinder horizontally-opposed double-crankshaft engine

Abstract

The invention relates to a two-in-one cylinder horizontally-opposed double-crankshaft engine. The engine comprises an engine spindle, and a first crankshaft spindle and a second crankshaft spindle are symmetrically connected to the two sides of the spindle respectively. The spindle, the first crankshaft spindle and the second crankshaft spindle are sleeved with a spindle gear, a first crankshaft gear and a second crankshaft gear respectively, wherein the spindle gear, the first crankshaft gear and the second crankshaft gear are meshed with one another. The first crankshaft spindle drives first pistons through first crankshaft sets and first connecting rods, and the second crankshaft spindle drives second pistons through second crankshaft sets and second connecting rods. The first pistons and the second pistons are arranged on the two sides of each air cylinder sleeve. Air intake and exhaust systems and oil injection ignition devices are arranged on the middle side walls of the air cylinder sleeves. The two-in-one cylinder horizontally-opposed double-crankshaft engine has the advantages that through the internal combustion engine, the heat losses are greatly lowered, the acting peak value of each cylinder is twice that of an original cylinder, the effective pressure of the pistons is increased, more oil can be saved by the engine, two original sets of air exhaust, air inlet, ignition and oil injection devices are combined into one set, the weight is lowered, the cost is saved, operation is stable and vibration is small.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to a two-cylinder integrated horizontally opposed double crankshaft engine. Background technique [0002] An internal combustion engine is a kind of power machinery, which is a heat engine that directly converts the heat energy released by burning fuel inside the machine into power. [0003] Internal combustion engines in a broad sense include not only reciprocating piston internal combustion engines, rotary piston engines and free piston engines, but also rotary impeller gas turbines, jet engines, etc., but internal combustion engines generally refer to piston internal combustion engines. [0004] Piston type internal combustion engine is the most common with reciprocating piston type. The piston-type internal combustion engine mixes fuel and air and burns it in its cylinder, and the heat energy released makes the cylinder generate high-temperature and high-pressure gas. The expan...

Problems solved by technology

[0005] At present, four pistons are generally arranged side by side. The piston rod of each piston is driven and connected by a crankshaft, and the four crankshafts are fixedly connected together. During the movement, the four pistons perform exhaust, suction, compression and work respectively. One of the three strokes, this structure has the following disadvantages: large volume and weight, high processing requirements, complex assembly, high cost, large energy loss during work, and more fuel consumption
