A control system for split type internal combustion engine

Abstract

The invention relates to a control system of an internal combustion engine, in particular to a control system of a split-type internal combustion engine. The control system of the split-type internal combustion engine comprises a power output portion, a power transmission portion, a control portion and an execution portion; the power output portion comprises a piston, a crankshaft and connecting rods; the power transmission portion comprises a crankshaft gear, a first camshaft gear, a second camshaft gear and a gear belt, wherein the crankshaft gear is a driving wheel, and the first camshaft gear and the second camshaft gear are driven wheels; the control portion comprises a first camshaft and a second camshaft; the execution portion comprises an air inlet device, an air exhaust device, a piston control device and an air combustion door control device which are separated from one another and all connected to the control portion. According to the control system of the split-type internal combustion engine, all mechanisms of the execution portion are controlled by power which is output by the crankshaft, the energy utilization rate is high, all the mechanisms can maintain a common control frequency, and stable running of the internal combustion engine is guaranteed. In addition, according to the control system of the split-type internal combustion engine, the energy consumption is low, and the action effect is strong.

Description

technical field [0001] The invention relates to a control system of an internal combustion engine, in particular to a control system of a split type internal combustion engine. Background technique [0002] The output power of the internal combustion engine can be increased by increasing the compression ratio of the internal combustion engine, but as the air is compressed, the air temperature will rise, the greater the pressure, the greater the temperature rise, and when the compression is large, the temperature of the supercharged gas will also be very high High, high-temperature compressed air enters the combustion chamber, which can easily cause the engine combustion room to be too high, causing knocking and other failures, so it is difficult to further increase the compression ratio. For example, CN103967587A discloses a split-cylinder type two-stage compression engine, which divides gas compression and work into two parts to complete, which solves the problem of excessi...

[0002] Increasing the compression ratio of the internal combustion engine can increase the output power of the internal combustion engine, but as the air is compressed, the air temperature will rise, the greater the pressure, the greater the temperature rise, and when the compression is large, the temperature of the supercharged gas will also be very high High, high-temperature compressed air enters the combustion chamber, which can easily cause the engine combustion room to be too high, causing knocking and other failures, so it is difficult to further increase the compression ratio

For example, CN103967587A discloses a split-cylinder type two-stage compression engine, which divides gas compression and work into two parts to complete, which solves the problem of excessive compression ratio. However, in the actual process, the valve opening and closing of the internal combustion engine and the piston The movement needs to be coordinated and controlled to achieve a good working condition
