Water spray intercooling system in piston reciprocation internal combustion engine pressure cylinder

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 in particular relates to a water spray cooling system in a supercharged cylinder of a piston reciprocating internal combustion engine. Background technique [0003] In China's invention patent ZL200710193938.X, a piston reciprocating supercharging mechanism in which the piston reciprocating internal combustion engine body is combined with the power mechanism is invented. The supercharging mechanism utilizes the working parts and the running space of the power mechanism. The pistons run synchronously and have the same stroke, the structure is simple and the transmission is direct, and its positive effects are: the instantaneous response lag of the existing turbocharging is eliminated, many auxiliary settings must be added, and the structure is complex and the work performance is poor. The ratio of large power to unsupercharged power) is low, and it is difficult to apply to the most wide...

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) is only used to vertically drive the pump head (29) of the special-shaped water spray nozzle, and there is no mechanism for relative lateral movement between the two, thus, the system only has the regulation and control of the amount of water sprayed. Without the control functions of buffering, timing, and constant rate, the lack of this function cannot be tolerated. The above defects and deficiencies must be overcome.
