Water-injection Cooling System in Supercharged Cylinder of Piston Reciprocating Internal Combustion Engine

Abstract

The invention discloses a water spray intercooling system in a piston reciprocation internal combustion engine pressure cylinder. A tappet head (7) arranged on a component (20) moving synchronous with an engine piston and used for fixing a tappet (24) makes a working shape similar to the working performance of a cam in the axial direction of a rockshaft (1) according to a connecting line of timing, quantified and fixed-rate working parameters of all working conditions from the lowest working condition to the highest working condition of the designed engine; and a rocker (6) is fixed to the rockshaft (1) connected with a shaft base in a sliding manner, when the rockshaft (1) does axial motion along with the engine working condition, the rocker (6) corresponds to a working parameter line of a certain working condition on the working shape, and a pump water spraying nozzle (30) works under the working parameter of the certain working condition on the working shape corresponding to the rocker (6).

Description

[0001] Field [0002] The invention belongs to the field of internal combustion engines, and specifically relates to a water-injection cooling system in a booster cylinder of a piston reciprocating internal combustion engine. Background technique [0003] China’s invention patent ZL200710193938.X invented a piston reciprocating pressurization mechanism in which the piston reciprocating internal combustion engine body is compounded with the power mechanism. The pressurization mechanism uses the working parts and operating space of the power mechanism. The piston of the booster cylinder and the engine cylinder The pistons run synchronously and have the same stroke, and the structure is simple and the transmission is direct. Its positive effect is: eliminating the transient response lag of the existing turbocharger, and it is necessary to add a lot of auxiliary settings. The structure is complex and the work performance is poor. The ratio of large power to unsupercharged power) is low...

AI Technical Summary

Problems solved by technology

[0005] The intercooler system in the above background consumes many working parts, and there are many moving parts and complex structure, which not only causes difficulties in manufacturing, installation and maintenance and increases the cost, but also leads to poor working performance, and it is difficult to meet the requirements of accuracy, stability and reliability. , especially if Figure 4 Shown: the side tappet head 28 only drives the pump head 29 of the special-shaped water nozzle vertically, and there is no mechanism for relative lateral movement between the two. Therefore, the system only has the regulation of the water spray volume, without buffering, Timing, fixed rate control function, the lack of this function is intolerable, the above defects and deficiencies must be overcome
