Description

Novel multi-cylinder internal combustion engine structure

Technical Field

The invention relates to an internal combustion engine, in particular to a novel multi-cylinder internal combustion engine structure.

Background

An internal combustion engine is a power machine, and is a heat engine that directly converts heat energy released by burning fuel inside the machine into power. The internal combustion engine in the broad sense includes not only reciprocating piston, rotary piston and free piston engines but also jet engines of the rotary vane type, but the internal combustion engine is generally referred to as a piston engine. Piston internal combustion engines are the most common of the reciprocating piston types. The piston type internal combustion engine mixes fuel and air and burns in a cylinder of the engine, and the released heat energy enables the cylinder to generate high-temperature and high-pressure fuel gas. The gas expands to drive the piston to do work, and then the mechanical work is output through a crank-link mechanism or other mechanisms to drive the driven machinery to work. Common diesel engines and gasoline engines convert internal energy into mechanical energy, and change the internal energy by doing work.

The efficiency of the traditional internal combustion engine is low, and the traditional internal combustion engine cannot be used in the current time.

Detailed Description

The structure of the novel multi-cylinder internal combustion engine is further described in detail with reference to the accompanying drawings.

With the attached drawings, the novel multi-cylinder internal combustion engine structure comprises an internal combustion engine box body 1, wherein a cylinder sleeve 2 is arranged in the middle of the internal combustion engine box body 1, a combustion chamber 3 is arranged in the middle of the cylinder sleeve 2, and an air inlet and exhaust hole 4, an oil injection hole 5 and a striking device 6 are arranged at the combustion chamber 3 on the cylinder sleeve 2;

a first crankshaft 7 and a second crankshaft 8 are symmetrically arranged at two ends of the internal combustion engine box 1, the extending direction of the crankshafts is perpendicular to the extending direction of the cylinder sleeve 2, a first connecting rod 9 is rotatably arranged on a connecting rod journal on the first crankshaft 7, and a first piston 10 is arranged in the cylinder sleeve 2 after the first connecting rod 9 extends; a second connecting rod 11 is rotatably arranged on a connecting rod journal on the second crankshaft 8, and a second piston 12 is arranged in the cylinder sleeve 2 after the second connecting rod 11 extends;

a constant speed connecting rod 13 is arranged on the first crankshaft 7 and the second crankshaft 8, one end of the constant speed connecting rod 13 is rotationally connected with a connecting rod journal of the first crankshaft 7, the other end is rotationally connected with a connecting rod journal of the second crankshaft 8,

the first crankshaft 7 and the second crankshaft 8 rotate at the same speed and in the same direction, and the positions of the connecting rod journal on the first crankshaft 7 and the connecting rod journal on the second crankshaft 8 are the same during rotation.

In the implementation of the invention, when the first piston 10 on the first crankshaft 7 is located in a position where the cylinder liner 2 is far away from the combustion chamber 3, the second piston 12 on the second connecting rod 11 is close to the combustion chamber 3; then through the cooperation of inlet and outlet hole 4, nozzle opening 5 and ignition device 6, realize the burning of oil in combustion chamber 3, at this moment, the inflation of the interior gas of combustion chamber 3 promotes second piston 12 and keeps away from combustion chamber 3 fast and outwards remove, first piston 10 on the first bent axle 7 makes first piston 10 remove to combustion chamber 3 because of the effect of inertia and the effect of constant speed connecting rod 13 to the space of compression combustion chamber 3, the inflation of combustion chamber 3 promotes second piston 12 and keeps away from combustion chamber 3 fast and the power of outwards removing is bigger.

The above motion patterns are reciprocated.
