Embodiment Construction

[0036] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.

[0037] Such as Figure 5 As shown, a control device for a partitioned and stratified lean-burn engine includes a cylinder 42 and a turbocharger 11 and an exhaust gas storage container 12 sequentially connected to its exhaust port. The exhaust gas storage container 12 is connected to the cylinder inlet through an exhaust gas return pipe 17 on the air pipe 20, so as to realize the recycling of exhaust gas; the cylinder 42 is connected to the cylinder head 1 at its top position; the control device also includes an electronic control unit 28 and an electromagnetic controller connected thereto; the cylinder head 1 is provided with a cylinder head partition The plate 2 and the top o...

Abstract

The invention discloses a zoned and layered thin combustion engine control device. The zoned and layered thin combustion engine control device comprises an electromagnetic controller, as well as a gas-in changeover valve I, a gas-in changeover valve II, an oil sprayer I and an oil sprayer II, which are respectively connected to an electronic control unit, wherein a combustion chamber is separated into a small combustion zone and a large combustion zone; cylinder gas-in pipes are respectively connected to the large combustion zone and the small combustion zone, a cylinder gas-in pipe shunting plate is arranged in each cylinder gas-in pipe, and each cylinder gas-in pipe is divided into a large gas-in pipe and a small gas-in pipe. As engine zoned and layered combustion is realized, when an automobile is at idle speed or carries small load or medium load, the combustion efficiency of fuel oil in the engine is improved, the oil consumption and the emitted exhaust gas of the engine are reduced, and the safe use of the engine during large load is ensured. Therefore, the environmental-friendly performance of the automobile during running is improved, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a control device for a partitioned and stratified lean combustion engine. Background technique [0002] At present, the most widely used automobile engine is the reciprocating piston engine, which achieves fuel economy through turbocharging at high speed and heavy load, but fails to achieve fuel economy at idle speed and light load, so it is used in the market. The fuel consumption is obviously too high when driving at low speed in the area. [0003] The reasons are as follows: (1) When the throttle valve is completely closed at idle speed, only a small amount of air enters the cylinder through the idle passage of the throttle valve, so that a large vacuum is formed when the air is inhaled, which will inevitably reduce the energy consumed by the intake air. increase, increasing the pumping loss; at the same time, because the vacuum degree of the intake pipe is very large at this...
