Embodiment Construction

[0042] The core of the present invention is to provide a management system, method and throttle valve detection mechanism for the partial cylinder closure of the engine when the vehicle is running. The management system can greatly reduce the fuel consumption of the engine, and at the same time, the operation is simple and easy, and the applicable range is relatively wide, and the operation is safe. Sex is relatively high.

[0043] Without loss of generality, this article takes a vehicle with a four-stroke gasoline engine as an example to introduce the technical solution. In order to enable those skilled in the art to better understand the technical solution of the present invention, the throttle detection mechanism, management system, control method, The accompanying drawings and specific embodiments further describe the present invention in detail.

[0044] The power of the vehicle engine is generally transmitted to the drive shaft connected to the wheel connecting plate thr...

Abstract

The invention discloses a management system and method for closing parts of cylinders of an engine. The management system can judge whether the current driving state of a vehicle meets the prestored partial cylinder closing driving conditions according to a driving speed signal, a throttle percentage signal and a brake signal and give out a control order of closing parts of cylinders and making the rest of cylinders work within a preset load range by taking the prestored partial cylinder closing driving conditions as conditions, namely control parts of the cylinders to be in a cylinder closing state and control the rest of the cylinders to work in the preset higher load range. Therefore, the throttle percentage of the cylinders working in this way is large, the airflow resistance is reduced greatly, air inflation performance is high, fuel oil is saved greatly, economical efficiency of an automobile gasoline engine is increased, specific fuel consumption of antifreeze and discharge of harmful gases can be reduced greatly, and environment protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a management system and method for partial cylinder deactivation of an engine. Background technique [0002] According to the different driving power of the car, the driving of the car can be roughly divided into two types: high-power driving state and driving state. Generally speaking, the high-power driving state refers to the engine working under heavy load when the car starts, accelerates, goes uphill, and runs at high speed with full load. That's rarely the case. In addition to the above several driving states, the rest can belong to the driving state. [0003] At present, when driving on a flat and good road, maintain a speed of about 100 km / h, and under the condition of light load, the engine works under partial load, and the actual power used is 30%-50% of the rated power. Especially for cars, the actual power used is 20%-30% of the rated power. This has a ...
