Four-cylinder self-supercharged engine

Abstract

The invention relates to the field of heat energy and power, in particular to a four-cylinder self-supercharged engine. The four-cylinder self-supercharged engine is a four-stroke internal combustion engine with four steam cylinders. The four-cylinder self-supercharged engine comprises the four steam cylinders, namely, the first steam cylinder, the second steam cylinder, the third steam cylinder and the fourth steam cylinder, a flow stabilizer, a first communicating channel, a second communicating channel and a third air door. The four-cylinder self-supercharged engine is characterized in that the second steam cylinder and the fourth steam cylinder are connected with the first communicating channel; the first communicating channel is connected with the second communicating channel through the third air door in a manner of being capable of being disconnected; the second communicating channel is connected with the first steam cylinder and the third steam cylinder; and after being shut down, the second steam cylinder and the fourth steam cylinder can be switched into superchargers, and supercharging air is provided for the first steam cylinder and the third steam cylinder. The four-cylinder self-supercharged engine has the beneficial effects that the existing cylinder deactivation technology is improved, two steam cylinders are switched into the superchargers after being shut down to supercharge the other two steam cylinders, and the supercharging effect is achieved; and the two superchargers are utilized for jointly supercharging the two corresponding steam cylinders, and a certain supercharging effect is achieved.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a four-cylinder self-supercharged engine. Background technique [0002] The existing cylinder deactivation technology (Cylinder deactivation) means that when the engine is running under partial load, some cylinders stop working, so that the load rate of the remaining working cylinders increases, so as to improve efficiency and reduce fuel consumption. However, the piston that shuts down the cylinder is still moving, has a moment of inertia, and wastes energy worthlessly. It is time to invent an engine that utilizes deactivated cylinder boosting. Contents of the invention [0003] The invention provides a four-cylinder self-supercharging engine, which improves the existing cylinder deactivation technology, and converts two cylinders into a supercharger after the two cylinders are deactivated to supercharge the other two cylinders to achieve a supercharging effect.
