Embodiment Construction

[0023] figure 1 Demonstrates the components of a balanced adjustable compression ratio and supercharged twin-cylinder engine and the relationship between the various parts. The twin-cylinder engine has two pistons, piston 1 and piston 2, and their matching cylinders. Some mature components of reciprocating piston engines, such as cylinders and cylinder heads, are omitted here. Piston 1 drives crankshaft 4 and piston 2 drives crankshaft 3. The axes of rotation of crankshaft 3 and crankshaft 4 are parallel. The compression ratio adjustment of the engine is completed by the two systems of eccentric wheel 5 and eccentric wheel 6. The eccentric wheel 5 includes the eccentric wheel, the wheel shaft and the hydraulic actuator. The actuator is driven by the high-pressure oil pump of the engine to rotate. Under control, when turning, it drives the eccentric wheel to rotate, thereby changing the up and down position of the support point of the rocker arm, thereby changing the top dead...

Abstract

The invention discloses a double-cylinder engine capable of evenly adjusting the compression ratio and mechanical supercharging. The double-cylinder engine comprises pistons, connecting rods of the pistons, two cranks, connecting rods of the cranks, a six-connecting-rod or seven-connecting-rod rocker arm system and connecting shafts with eccentric wheels; the double-cylinder engine is combined by the pistons, the connecting rods of the pistons, the two cranks, the connecting rods of the cranks, the six-connecting-rod or seven-connecting-rod rocker arm system and the connecting shafts in a balancing mode. Eccentric wheels are adopted as rocker arm shafts; when the eccentric wheels rotate, fulcrums of rocker arms move upwards, dead centers on the pistons rise, and the compression ratio is improved. The rocker arms enable the motion direction of the connecting rods of the pistons to be opposite to the motion direction of the connecting rods of the cranks; and the double-cylinder engine obtains the better balance through the proper weight matching and balance blocks on the double cranks. The double-cylinder engine is obtained through a high-power, high-density and high-efficiency engine technology which is close to the ideal characteristics.

Description

technical field [0001] The invention relates to an internal combustion engine, especially a balanced twin-cylinder engine with adjustable compression ratio and supercharging, which has the ability to adjust the compression ratio and can adjust the equivalent displacement of the engine. Background technique [0002] The effect of the variable compression ratio internal combustion engine is that a turbocharger with a higher boost pressure can be used with a minimum of turbo lag. The adverse effect of turbo lag is the most important obstacle to increase the turbocharger compression ratio. As the boost pressure of the turbocharger increases, the turbo lag effect becomes more obvious. The method of changing the position of the top dead center of the piston is a commonly used variable compression ratio method, but there is no mature and reliable application of this kind of technology at present, because changing the basic structure of the Alto internal combustion engine brings var...
