Abstract
The utility model relates to a novel air-in and air-out system of an internal combustion engine, which is characterized in that the air-in and air-out system of an internal combustion engine is composed of a cylinder cover, a valve, an air-in one-way valve, an air-out one-way valve, a camshaft, etc., wherein the air-in one-way valve and the air-out one-way valve are made of elastic metal sheets; one end of the utility model is fixed, and the other end is movable, and the utility model is arranged in an air-in and air-out passage of a cylinder cover which is provided with an air-in and air-out common valve. The utility model has a working principle that when the internal combustion engine is in the air-in or air-out process, the valve not only can be used for air inlet, but also can be used for air outlet; opening and closing of an air-in port and an air-out port are controlled through the air-in one-way valve and the air-out one-way valve, and mixing of new air and waste air can be prevented. Thus, large through capacity of the gas can be obtained with fewer valves, and high-efficiency air exchange can be realized.
Description
Technical field
The utility model belongs to technical field of traffic transportation.
Background technique
Modern Internal-Combustion Engine is to send bigger power, and its rotating speed is more and more higher; This just requires intake and exhaust rapider, and many for this reason internal-combustion engines adopt 4 or 5 valves, though improved intake and exhaust efficient like this, also makes the air inlet system and exhaust system structure become complicated, and cost increases, and reliability reduces.
-the utility model content
The purpose of this utility model provides a kind of each cylinder and only needs a valve, but its intake and exhaust efficient is higher than the internal combustion engine air inlet system and exhaust system of common 4 or 5 valves.
Structure of the present utility model is made up of cylinder head, valve, exhaust check valve, camshaft, valve spring, breather check valve etc.Wherein breather check valve, exhaust check valve are made with elastic sheet metal, and an end is fixed on the intake and exhaust port, the other end activity; Place on the cylinder head in the intake and exhaust port, the shared valve of intake and exhaust is housed on the cylinder head.
Working principle: during internal combustion engine, bent axle drives camshaft and rotates, and when internal-combustion engine was in exhaust stroke, cam pushed away valve downwards and opens, and the gas in the cylinder is discharged from valve; Enter the intake and exhaust port in the cylinder head; This moment, the pressure official post exhaust check valve of exhaust check valve both sides was opened, and breather check valve is closed; Waste gas enters outlet pipe by exhaust check valve; Up along with piston, waste gas in the cylinder progressively is excluded, when exhaust stroke finishes, descent of piston sucks gas reduces atmospheric pressure, exhaust check valve is closed by self elastic force, breather check valve is opened under the action of pressure of both sides, and live gas enters cylinder through breather check valve and valve.Descent of piston is when the lower dead center, and valve is closed gradually, and breather check valve is also closed by self elastic force, finishes once ventilation.The utility model each cylinder when ventilation only needs a valve, and valve is in opening state always when ventilation, and the airflow area is big, intake and exhaust efficient height.
Description of drawings
Accompanying drawing is a structural drawing of the present utility model, (1) exhaust check valve, (2) breather check valve, (3), cylinder head, (4) camshaft, (5) valve spring, (6) valve, (7) cylinder, (8) piston, (9) intake and exhaust port among the figure.
Embodiment
The utility model can directly be loaded on cylinder of internal combustion engine and cover, and replaces the distribution device of existing internal-combustion engine, and the utility model is specially adapted to the distribution of the following internal-combustion engine of four cylinders.
