Problems solved by technology

When we choose a ship engine, we often need to choose a high-power main engine to ensure the speed of the ship. In most daily use cases, in order to consider economy, we will use long strokes and reduce the propeller speed to effectively increase the speed of the propeller. efficiency, the load rate of the main engine of the ship is often not so high

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0021] The invention provides a diesel engine cylinder closed cycle system, whose working principle is to replace the mechanical camshaft system and its transmission mechanism to control the opening and closing of the fuel injection port and the air injection port through ECM electronic control, so as to stop the work of this cylinder, so that The other cylinders work at a higher load rate, which improves the emission performance of the fuel consumption rate of the main engine, improves the emission performance of the fuel consumption rate, realizes precise timing control of the cylinders, and improves the utilization rate of the main engine Purpose.

[0022] The present invention will be described in further detail below in conjunction with examples and specific implementatio...

Abstract

The invention discloses a diesel engine closed-cylinder circulation system. The diesel engine closed-cylinder circulation system comprises a diesel engine control module, a gas distribution module insignal connection with the diesel engine control module through a sensor and an oil supply module. ECM electronic control replaces a mechanical camshaft system and a transmission mechanism of the mechanical camshaft system to control opening and closing of an oil spraying opening and an air spraying opening, the work of an air cylinder is stopped, thus other air cylinders work in a high load ratestate, emission performance of the fuel consumption rate of a main machine becomes better, and the purposes of improving the emission performance of the fuel consumption rate, realizing timed accuratecontrol over the air cylinders and increasing the utilization rate of the main machine are achieved.

Description

technical field [0001] The invention relates to the field of production and application of diesel engines, in particular to a closed cylinder circulation system of diesel engines. Background technique [0002] According to the characteristics of the diesel engine, when the load rate of the main engine is low, the fuel utilization rate is low; when the load rate of the main engine is high (about 80% to 90%), the fuel utilization rate is high, and the emission performance becomes better. When we choose a ship engine, we often need to choose a high-power main engine to ensure the rapidity of the ship. In most daily use cases, in order to consider economy, we will use long strokes and reduce the propeller speed to effectively increase the speed of the propeller. The efficiency of the ship's main engine is often not so high. How to make the mainframe meet the needs of the use from the limited consideration of the economical situation is an urgent problem to be solved. Contents...
