Embodiment Construction

[0028] As mentioned in the background technology, in order to achieve the purpose of saving fuel, when the automobile does not need strong power, some cylinders can be stopped working, and when more power is needed, the original normal working state can be restored. The present invention provides a cylinder deactivation control device, which includes: a first intake pipe connected to the intake ports of the first group of cylinders; a first exhaust pipe connected to the exhaust ports of the first group of cylinders; a second intake pipe connected to the intake ports of the second group of cylinders; a second exhaust pipe connected to the exhaust ports of the second group of cylinders; and an intake control valve arranged at the second intake port On the air pipe, it is used to control the opening and closing of the second air intake pipe. Therefore, when the car does not need strong power, the second air intake pipe can be closed to prevent air from entering the second group o...

Abstract

The invention discloses an engine and a cylinder deactivation control device for the engine. The engine comprises a first group air cylinder and a second group air cylinder. The cylinder deactivation control device comprises a first air inlet pipe, a first air discharging pipe, a second air inlet pipe, a second air discharging pipe and an air intake control valve, wherein the first air inlet pipe communicates with an air inlet of the first group air cylinder; the first air discharging pipe communicates with an air outlet of the first group air cylinder; the second air inlet pipe communicates with an air inlet of the second group air cylinder; the second air discharging pipe communicates with an air outlet of the second group air cylinder; and the air intake control valve is arranged on the second air inlet pipe and is used for controlling opening and closing of the second air inlet pipe. The cylinder deactivation control device is simple in structure, low in manufacturing cost and easy to implement.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an engine and a cylinder deactivation control device thereof. Background technique [0002] Auto cylinder deactivation control device, or variable displacement technology, is a fuel-saving technology. Its fuel-saving principle is: when the car does not need strong power, such as when driving at low speed or idling, some cylinders can stop working; The load rate of the engine achieves the purpose of saving fuel. [0003] At present, the stop of some cylinders is realized by closing the intake valve or the oil circuit. However, by closing the intake valve of the cylinder so that the cylinder stops working, the control system has a complex structure and high cost. By closing the oil circuit to stop the cylinders from working, the temperature of the normal working cylinders is higher, while the temperature of the stopped cylinders is lower, so thermal stress will be generated between di...
