Problems solved by technology

[0004] Generally speaking, the reason why the thermal efficiency of the existing piston four-stroke engine does not exceed 30% is that its explosion energy is not fully utilized, nor can it be fully utilized, which is far from the theoretical efficiency.
The compression ratio of the engine determines that the excess energy in the explosion action must enter the next working procedure to be exhausted, and most of the effective energy is not used, so it is discharged in vain

Embodiment Construction

[0038] As shown in the figure, the device of eight-stroke engine: consists of main crankshaft 1, auxiliary crankshaft 2, connecting rod 3, 4, piston pin 5, 6, piston 7, 8, piston ring 9, 10, main cylinder 11, 13, 15 , 17, auxiliary cylinders 12, 14, 16, 18, fuel injectors 19, spark plugs 20, intake valves 21, exhaust valves 22, 26, communication air passages 23, communication valves 24, breathing valves 25, electric valves (electromagnetic valve) 27, synchronizer 28, breathing valve camshaft 29, valve bridge 30.

[0039] There are two identical crankshafts 1 and 2 placed in parallel in the crankcase. Crankshaft 1 is the main crankshaft and has an output end, and crankshaft 2 is the auxiliary crankshaft. The synchronizer 28 makes the two crankshafts rotate at the same time, at the same speed and in the same direction. .

[0040] One row of main cylinders 11, 13, 15, 17 and one row of auxiliary cylinders 12, 14, 16, 18 are arranged in a straight line and horizontally in paralle...

Abstract

The invention relates to an eight-stroke engine which consists of a primary air cylinder four-stroke system and a secondary air cylinder four-stroke system. The eight-stroke engine comprises primary and secondary crank shafts (1 and 2), connecting rods (3 and 4), pistons (7 and 8), an assembly of primary and secondary air cylinders (11 and 12), an air suction door (21), air exhaust doors (22 and 26), an assembly of a communication air door (24) and an air breathing door (25), a cooling system and a lubrication system, wherein only the primary air cylinders (11) are provided with ignition and fuel supply assemblies, each primary air cylinder (11) and a corresponding secondary air cylinder (12) are connected and communicated with each other through a communication air passage (23) and form a group, the communication air passage (23) is opened / closed by the communication air door (24) and an electric valve (27) according to set working procedures, and the primary air cylinders (11) and the pistons (7 and 8) in corresponding secondary air cylinders (12) are respectively connected with the primary crank shaft (1) and the secondary crank shaft (2) through the connecting rods (3 and 4). According to the eight-stroke engine, the power and the efficiency of the engine are maximized.

Description

technical field [0001] The invention relates to methods and devices for moving power and generating power, in particular to methods and devices for working with internal combustion engines. Background technique [0002] The engine of the Carnot cycle has a history of 100 years, and its working principle is: suction, compression, explosion, and exhaust. With the development of science and technology, the performance of the engine has also been continuously improved, such as adding valves, turbocharging, electronic injection, direct injection in the cylinder and other technologies, but the thermal efficiency of the engine has not been able to exceed 30%. In the context of the global oil and environmental crisis, improving the thermal efficiency and environmental protection emissions of engines is of great and far-reaching significance to the development of society. [0003] CN200810007618 proposes a kind of eight-stroke engine, and this engine has the working cylinder by burn...
