Intake and exhaust interconnected piston supercharged energy-saving engine

technical field

The utility model relates to an engine, in particular to an intake and exhaust interconnected piston supercharged energy-saving engine which utilizes the pressure when the engine cylinder is exhausted to pressurize the working cylinder. the

Background technique

With the gradual depletion of consumable energy, the problem of energy saving and emission reduction of vehicles is more prominent in the world. In order to ensure driving safety, various countries limit the maximum speed of vehicles, so that there is no flexible and interactive application between the output power of the engine and the road conditions and loads. Simultaneously, when the engine is in a general low-speed working state, not all cylinders are all involved in the power output, and the piston will idle with the crankshaft, which will inevitably cause energy loss and increase fuel consumption. the

Contents of the invention

The purpose of the utility model is to propose an intake and exhaust interconnected piston supercharged energy-saving engine that can adjust the intake pressure of the working cylinder in real time according to the road conditions and the load of the vehicle to help the working piston to assist. the

The purpose of this utility model is achieved in this way: the intake and exhaust interconnected piston supercharged energy-saving engine includes at least four cylinders, and the cylinder side walls of all cylinders are connected with intake pipes and exhaust manifolds. A booster pipe is communicated between the opposite air cylinders. the

Detailed ways

The utility model is not limited by the following examples, and the specific implementation manner can be determined according to the technical scheme of the utility model and actual conditions.

Embodiment: As shown in Figure 1, the intake and exhaust interconnected piston supercharged energy-saving engine includes at least four cylinders, and the cylinder side walls of all cylinders are connected with intake pipes and exhaust manifolds. A booster pipe is communicated between the cylinders. No. 1 cylinder boost port 2 and No. 4 cylinder boost port 7 are respectively separated in No. 1 and No. 4 cylinder intake pipes 1 and 8 of No. 1 and No. 4 cylinders 18 and 9 . On No. 2 and No. 3 cylinders 4 and 5, No. 2 cylinder exhaust manifold 15 and No. 3 cylinder exhaust manifold 12 are respectively equipped with left booster three-way valve 16 and right side booster three-way valve 11 . There is a left booster pipe 14 connected between the booster port 2 of the aforementioned No. 1 cylinder and the left booster three-way valve 16, and a right booster pipe 14 is connected between the booster port 7 of the fourth cylinder and the right booster three-way valve 11. Tube 13. the

It is also possible to cancel the connection of the left and right booster pipes 14, 13 with the booster port 2 of the No. 1 cylinder and the booster port 7 of the No. 4 cylinder. Connected, the connected part is located before the air filter element. the

When cylinder reaches six cylinders and above, left and right booster pipes 14, 13 can be communicated by pipeline in the middle section. the

When the No. 1 cylinder ignites and works, the left booster three-way valve 16 can be closed, so that the No. 2 cylinder exhaust manifold 15 is closed, and the left side booster pipe 14 conducts the No. 1 cylinder and the No. 2 cylinder. When the piston of the No. 2 cylinder is idling with the crankshaft, the unburned air is pumped into the No. 1 cylinder through its exhaust manifold, thereby increasing the pressure in the No. 1 cylinder and helping to save fuel. The exhaust gas generated after combustion in the No. 1 cylinder is discharged from the exhaust manifold 17 of the No. 1 cylinder. the

In the same way, when the No. 4 cylinder is ignited, the right three-way valve 13 can be closed accordingly, so that the unburned air in the No. 3 cylinder enters the No. 4 cylinder, increasing the pressure in the No. 4 cylinder and saving fuel. The exhaust gas produced after combustion in the No. 4 cylinder is discharged by the exhaust manifold 10 of the No. 4 cylinder. the

The structure of the utility model is suitable for various piston engines such as V-shaped, W-shaped, horizontally opposed, supercharged, and turbocharged. the

The above technical features constitute the best embodiment of the utility model, which has strong adaptability and best implementation effect, and non-essential technical features can be increased or decreased according to actual needs to meet the needs of different situations. the
