Abstract

We configure the engine to fit the mechanism (figure 1,2,3,4,5) inside. The mechanism is mounted on the engine’s body and is connected with the piston (Figure 1-point M) and the crankshaft (Figure 1-point S) in a hinged manner. The piston oscillates according to the rotation of the crankshaft, but its path and speed are determined by the mechanism (figure 1,2,3,4,5). All other functions of the engine remain the same. This engine is liable to operate as a square, super-square, or sub-square motor functioning form a minimum and a maximum engine capacity. It is a smart engine quickly adaptable to the user’s requirements by controlling and changing the compression ratio.

Description

W-shaped variable piston engine

Description

The present invention relates to a reciprocating piston internal combustion engine which operates in the same way as a conventional engine and in addition varies the stroke distance and the speed of the piston or pistons without depending on the rotation of the crankshaft present in the engine.

In pre-existing engines, the distance and speed of piston travel is determined by the crankshaft present in the engine.

The object of the present invention is to provide a new mode of operation of the engine, which will vary the stroke and speed of the piston during its operation independently of the crankshaft to which it is connected.

The engine increases or decreases its displacement within defined frames and changes the compression ratio within a minimum of time.

In this way the engine is better adapted to the various conditions and requirements we need, while still meeting the intense specifications of the scope and especially of the purpose of manufacture.

To achieve our goal we have to configure the engine so that we can add the mechanism inside it (figure 1,2,3,4,5).

The mechanism is attached to the main body of the engine and is connected between the crankshaft (figure 1 - point S) and the piston (point M) in a hinged manner.

The mechanism (figure 1), consists of points A, B, C, D, G, F.

The mechanism (figure 2) expands and consists of many double identical points.

The mechanism (figure 3) expands and consists of many quadruple identical points.

Point A (figure 1 ) is a movable point to which the plunger of the piston point F is connected in a hinged way and slides to a part of the point AB, approaching or moving away from the point B and in this way we increase or decrease the stroke and piston speed.

Point D (figure 1), is a movable part of the mechanism that is fixed to the engine body and moves up and down in a controlled manner and as it is connected to point A through the shaft (point G), it moves point A following a certain path in point AB, slides and approaches or moves away from point B. Point G (figure 1) is the axis connecting point A to point D in a hinged manner.

Point B (figure 1) is where the mechanism is attached to the engine body and allows point A to reciprocate the piston.

Point C (figure 1) is where the mechanism connects to the crankshaft pusher in a hinged manner.

In this mechanism we connect a piston (figure 1) or several pistons (figure 2,3).

The mechanism (figure 1), creates a controlled slide of point A and changes its position approaching or moving away from point B.

The same happens in the case that the mechanism (figure 2,3) is extended and has many identical points A.

In this way, we change the stroke and the speed of the piston (the further away from point B, the greater the stroke and speed of the piston, while when it approaches point B it decreases accordingly).

And so we have a maximum size of the total displacement of the engine and a minimum (the engine operates in the entire intermediate range).

Also, with this mechanism, the engine has the ability to change the compression ratio.

The crankshaft still makes exactly two full revolutions for the engine to fulfill all four of its operating times.

The mechanism may differ visually in each case, but its function remains the same in all cases.

The points A1, B, A2 of the mechanism (figure 2) form an angle (figure 6,7,8).

Depending on the angle of the mechanism we achieve the desired result. Points A1B and BA2 in Figure 2 are two straight lines. On part of them, the points A1, A2 slide in a controlled manner.

We also give a different shape to these lines (figure 8).

Depending on the shape we achieve the desired result.

Claims (3)

1 A reciprocating piston internal combustion engine which, during its operation, varies the distance of the stroke and the speed of the piston or pistons, thereby operating as a square, under-square or over-square engine. We configure the engine so that it includes one or more mechanisms inside it (figure 1,2,3,4,5). This mechanism is fixed to the main body of the engine (figure 1) at point B, and is connected between the crankshaft (point S) and the piston (point M) in a hinged manner. Point A (figure 1), is a movable point to which the pusher (point F) is connected in a hinged manner and slides to a part of point AB, approaching or moving away from point B. In order for the mechanism to change the path and speed of the piston, it must move point A in a controlled manner (figure 1). Point A (figure 1) is hingedly connected through the shaft (point G) to point D. Point D is the part of the mechanism that moves point A, it is attached to the engine body and moves up and down in a controlled manner and as it is connected to point A it moves and slides on point AB approaching or moving away from point B (figure 1 ). The farther point A is from point B, the greater the stroke and speed of the piston, while as it approaches point B it decreases accordingly. The same happens in the case that the mechanism (figure 2, 3) is extended and has many identical moving points A. 2. Reciprocating internal combustion piston engine where according to claim 1, it is characterized by changing the stroke and speed of the piston independently of the crankshaft present in the engine. 3 Reciprocating piston internal combustion engine according to claim 1 characterized by changing the compression ratio of the engine.
