Adjusting and controlling system for piston reciprocating internal combustion engine

Abstract

The invention discloses an adjusting and controlling system for a piston reciprocating internal combustion engine. Two left and right adjusting and controlling shafts (3, 9) are correspondingly formed by connecting first, second and third shaft segments (56,46, 38) with two front and rear shaft segments (17, 26) in series, and can slide in a shaft base hole in the axial direction; first, second, third and fourth fixing rocker arms (47, 52, 20, 24) are connected with a first cam (45), a second cam (53), a front cam (19) and a rear cam (23) correspondingly; the shapes of the cam are correspondingly given in the adjusting and controlling axis direction according to a connecting line of work parameters of a work system connected with first, second, third and fourth special-shaped rocker arms (24, 54, 21, 31) under each work cycle from the lowest work condition to the highest work condition of the engine; and when the engine works, the two left and right adjusting and controlling shafts synchronously move along with the work condition of the engine, and the work system connected with the first, second, third and fourth special-shaped rocker arms and a work system connected with a tail moving cam (39) of the third shaft segment (38) of the left adjusting and controlling shaft uniformly and synchronously work under corresponding work parameters along with the change of the work condition of the engine.

Description

[0001] Field [0002] The invention belongs to the field of piston reciprocating internal combustion engines, and in particular relates to the control technology of the working system of piston reciprocating internal combustion engines. Background technique [0003] Published invention patent application 201610591280.7 "Piston reciprocating internal combustion engine integrated control system" (publication date 2016.11.02, publication number CN106065837A), in order to overcome the Chinese invention patent ZL201110283190.9 "a piston reciprocating internal combustion engine top integrated control system" The "supercharged cylinder intake air volume control system" and "supercharged cylinder intercooler water spray system" have complex structures, poor performance, and the patented top-mounted comprehensive control system uses one control shaft to control only one job A new invention has been made due to the defects and deficiencies of the complex structure of the system.

AI Technical Summary

Problems solved by technology

[0007] To sum up the above two paragraphs, if the existing integrated control system is applied to an engine with a long piston stroke, especially a large low-speed engine, the operation of the tappet head will inevitably increase the height of the engine volume and occupy a large amount of space on the engine roof plate. space, therefore, the integrated control system of the above-mentioned background technology is limited to the application on the short-stroke piston reciprocating engine
