Abstract
The invention relates to a catalyst separation type cylinder deactivation technology engine. The engine comprises an intake manifold, air cylinders, an exhaust manifold and a catalyst. The catalyst is a separation type three-way catalyst and composed of a first catalyzing cavity and a second catalyzing cavity. Fuel injectors are arranged on the air cylinders and connected with an electronic control system. One ends of the air cylinders are connected with the intake manifold, and the other ends of the air cylinders are connected with the exhaust manifold. The exhaust manifold converges into a first exhaust pipe and a second exhaust pipe at the vent end, the first exhaust pipe is connected with the first catalyzing cavity, and the second exhaust pipe is connected with the second catalyzing cavity. A throttling valve body is arranged at the front end of the intake manifold, and the tail end of the separation type three-way catalyst is connected with a rear exhaust pipe. The catalyst separation type cylinder deactivation technology engine is simple in structure, reasonable in design, convenient to use and low in manufacturing cost; while the design of an engine body is kept unchanged, fuel consumption is greatly reduced, driving cost and environmental pollution are reduced, and a forward-looking, efficient and low-cost oil consumption solving scheme is provided.

Background technique
At present, along with world petroleum resource is in short supply, automobile industry is had higher requirement to the fuel economy of vehicle.For this reason, in technical field of engines, along with falling the development of oil consumption new technology, and its interruption cylinder technology performance is particularly outstanding.The cylinder but the motor of present stage breaks, that the mechanical mechanism that leans against a set of complexity of increase in cam phase regulates to realize disconnected cylinder, greatly degree has increased structural complexity, control difficulty and the cost of production of motor, so need a kind of a kind of disconnected Cylinder engine simple in structure, easy realization meet the fuel economy regulation that follow-up Economy improves constantly.
Summary of the invention
The object of the invention is to overcome the deficiency existing in above-mentioned technology, a kind of reasonable in design, simple is provided, be convenient to the catalyst converter separated type cylinder stopping technique motor of realizing.
In order to achieve the above object, the technical solution used in the present invention is: comprise intake manifold, cylinder, gas exhaust manifold and catalyst converter, described catalyst converter is separated type ternary catalyzing unit, by the first catalytic chamber and the second catalytic chamber, formed, described cylinder is provided with oil sprayer, described oil sprayer is connected with electronic control system, one end of cylinder is connected with intake manifold, the other end is connected with gas exhaust manifold, described gas exhaust manifold converges in outlet side for downtake pipe and second exhaust pipe, downtake pipe is connected with the first catalytic chamber, second exhaust pipe is connected with the second catalytic chamber, the front end of described intake manifold is provided with throttle body, the tail end of separated type ternary catalyzing unit is connected with final vacuum pipe.
Advantage of the present invention is:
Simple in structure, reasonable in design, easy to use, low cost of manufacture, keeping engine body to design constant in the situation that, greatly reducing fuel consume, reduced driving cost and environmental pollution, is a kind of oil consumption solution of forward-looking, high efficiency, low cost.

Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
From Fig. 1-Fig. 2, the present invention includes intake manifold 1, cylinder 2, gas exhaust manifold 3 and catalyst converter, described catalyst converter is separated type ternary catalyzing unit 4, by the first catalytic chamber 5 and the second catalytic chamber 6, formed, described cylinder 2 is provided with oil sprayer 7, described oil sprayer 7 is connected with electronic control system 8, one end of cylinder 2 is connected with intake manifold 1, the other end is connected with gas exhaust manifold 3, described gas exhaust manifold 3 converges in outlet side for downtake pipe 9 and second exhaust pipe 10, downtake pipe 9 is connected with the first catalytic chamber 5, second exhaust pipe 10 is connected with the second catalytic chamber 6, the front end of described intake manifold 1 is provided with throttle body 11, the tail end of separated type ternary catalyzing unit 4 is connected with final vacuum pipe 12.
The number of the described gas exhaust manifold 3 being connected with second exhaust pipe 10 with downtake pipe 9 is identical.
The specific embodiment of the present invention for convenience of description, the four cylinder engine of take describes as example, first four cylinders are divided into two groups, guaranteeing on the basis of engine luggine performance, two cylinders in the middle of being positioned at are as first group of cylinder, its gas exhaust manifold 3 converges for being connected with the first catalytic chamber 5 of separated type ternary catalyzing unit 4 after downtake pipe 9, in like manner, using two cylinders that are positioned at two ends as second group of cylinder, its gas exhaust manifold 3 converges for being connected with the second catalytic chamber 6 of separated type ternary catalyzing unit 4 after second exhaust pipe 10, motor is when entering disconnected cylinder state, by electronic control system 8, provide disconnected cylinder order, two groups of cylinder mask works, oil sprayer 7 normal operations of first group of cylinder, the oil sprayer 7 of second group of cylinder stops oil spout under the control of electronic control system 8, valve is normally opened, fresh air directly enters gas exhaust manifold 3 by second group of cylinder.The gas of two groups of cylinder discharges enters respectively respectively the first catalytic chamber 5 and second catalytic chamber 6 of separated type ternary catalyzing unit 4 by downtake pipe 9 and second exhaust pipe 10, the high-temp waste gas of first group of cylinder enters after the first catalytic chamber 5, catalyzed processing, enter final vacuum pipe 12, the exhaust of second group of cylinder is fresh air, during through the second catalytic chamber 6, there is not catalytic reaction, directly enter final vacuum pipe 12 and discharge.
For guaranteeing that the first catalytic chamber 5 and second catalytic chamber 6 of separated type ternary catalyzing unit 4 all remains on efficacious workaround all the time, when the temperature of the second catalytic chamber 6 connecting when second group of cylinder drops to efficient district limit value, electronic control system 8 is sent switching command, second group of cylinder connected oil sprayer 7 started working, first group of oil sprayer that cylinder connects 7 stops oil spout, and working method as mentioned above.While needing four cylinder engine working state, motor is as normal four-cylinder work, and the first catalytic chamber 5 and second catalytic chamber 6 of separated type ternary catalyzing unit 4 are carried out catalytic reaction simultaneously.
