Description

AIR / FUEL DOUBLE PRE-MIX SELF-SUPERCHARGING INTERNAL COMBUSTION ENGINE WITH FREEWHEELING MECHANISM}

The present invention relates to a new type of internal combustion engine including a gasoline engine or a diesel engine. More specifically, the present invention provides a new type of air / fuel double mixing that includes a double crankshaft and a freewheeling mechanism that allows one or more engine pistons of the engine to not operate under specific operating conditions, thereby saving fuel. It is about a self-charging engine.

In a conventional internal combustion engine, wear of the engine is reduced and operating efficiency and fuel consumption are improved when the vibration of the engine is minimized. Or some of the pistons may not be operated for a certain time when maximum power is not needed. Vibration is reduced in a dynamically balanced engine. However, conventional engines with only one crankshaft and four, six or eight pistons firing in sequence have been difficult to achieve dynamic balance. If the engine has more than one crankshaft, the dynamic balance can be improved.

In a conventional internal combustion engine, engine speed is measured in revolutions per minute (rpm) of the crankshaft. Running the engine at high rpm means running more cycles for a given time. Thus, the moving engine parts travel longer distances and the wear of the engine is increased. Conventional continuous piston ignition internal combustion engines with one crankshaft are inherently not dynamically balanced, but can be better balanced when operated at high rpm. High rpm tends to resolve the imbalance. The engine with two crankshafts and the accompanying plurality of pistons and cylinders can be better balanced and run smoothly. Turbocharged engines operating at high compression rates improve fuel consumption and save fuel.

The present invention relates to a self-charging internal combustion engine, comprising: (a) a first triple piston and cylinder combination reciprocally connected to a first crankshaft, (b) a second crankshaft. A secondary triple piston and cylinder combination reciprocally connected, and (c) a first crankshaft and a second crankshaft connected by a combination of gears,

The first combination of three pistons and cylinders comprises: (i) a first piston and a first cylinder with an intake valve and an exhaust valve, (ii) a second piston and a second cylinder with an intake valve and an exhaust valve, And (iii) a third piston and a third cylinder whose size is at least twice the size of the first and second pistons and the first and second cylinders,

The second combination of three pistons and cylinders comprises: (i) a fourth piston and a fourth cylinder with an intake valve and an exhaust valve, (ii) a fifth piston and a fifth cylinder with an intake valve and an exhaust valve, And (iii) a sixth piston and a sixth cylinder whose size is at least twice the size of the fourth and fifth pistons and the fourth and fifth cylinders,

The first piston is connected to the first crankshaft at the first position, the second piston is connected to the first crankshaft at the third position, and the third piston is configured to allow air and fuel to flow into the third cylinder. A valve, the third cylinder being alternately connected with the intake valves of the first and second pistons and the first and second cylinders, the third piston being the first crank at a second position between the first and third positions. Connected to the axis,

The fourth piston is connected to the second crankshaft at the first position, the fifth piston is connected to the second crankshaft at the third position, and the sixth piston allows air and fuel to flow into the sixth cylinder. A valve, the sixth cylinder is alternately connected to the intake valves of the fourth and fifth pistons and the fourth and fifth cylinders, and the sixth piston has a second crankshaft at a second position between the first and third positions. Connected to the

The first crankshaft and the second crankshaft are parallel to each other, and the first crankshaft causes the first crankshaft to transmit a positive driving force to the second crankshaft while the second crankshaft is positively coupled to the first crankshaft. It includes an automatic freewheeling mechanism that does not transmit a driving force.

This pair of engine structures results in more efficient combustion, better mechanical balance, less vibration, more power and less emissions through a smaller engine size.

When the engine is running smoothly, fuel consumption is low, vibration is reduced, exhaust gases are reduced, friction is reduced and power can be generated more effectively.

In the second embodiment of the invention, FIG. 7 is provided with three cylinders / pistons, with two crankshafts labeled A and B, and one of the crankshafts with a freewheeling mechanism 34.

The freewheeling mechanism is a one-way drive mechanism. Freewheeling mechanisms are disclosed in Chapter 31 of Automotive Engineering (William H. Crouse, Publisher: McGraw-Hill). In the freewheeling mechanism, the positive driving force is transmitted to the second shaft or the second wheel by the first shaft or the first wheel. However, the second shaft or the second wheel cannot drive the first wheel or the first shaft. If the first axis or the first wheel is slowed down or stopped, the second axis or the second wheel is "freewheel" and continues to rotate. In the description of the clutch or planetary gear set, the freewheeling mechanism is sometimes described as an overrunning clutch. The freewheeling mechanism may be a sprag clutch, a centrifugal clutch, a bicycle clutch, a solenoid clutch, a hydraulic clutch, a pneumatic clutch, or other suitable It may include clutches.

As shown in FIGS. 7 and 8, when the freewheeling mechanism 34 is installed on the crankshaft A, two pistons 60, driven by fuel injected into the air / fuel compression chamber above the piston 62, 64 drives the crankshaft B, and this operation is transmitted to the next crankshaft A via the gear 45. Similarly, the two pistons 3, 4 driven by fuel injected into the compression chamber 30 above the piston 31 drive the crankshaft A. However, when the vehicle driven by the engine is inertia running or the engine is idling, fuel supply is continued to the set B having three pistons, but with three pistons 3, 31, and 4 The fuel supply is stopped in the set A, and the set A of pistons is idle by the freewheeling mechanism 34 to save fuel.

FIG. 10 is a top cutaway view of a pair of supercharged engines with three cylinders / pistons, with two crankshafts installed, with freewheeling mechanisms on all of the crankshafts.

9 and 10, when the second freewheeling mechanism 66 is installed on the crankshaft A, the crankshaft and piston / cylinder depending on which crankshaft and piston / cylinder combination is the power train. Any one of the combination (A) and the combination (C) of the crankshaft and the piston / cylinder can be idled. In this way, wear over time can be constant during the running time of the engine. The wear rate tends to be higher than in a crankshaft and piston / cylinder combination that is idling in the power generating crankshaft and piston / cylinder combination. By using two freewheeling mechanisms on each crankshaft, one crankshaft and a combination of piston / cylinder can be a power train for a period of time, while the other crankshaft and a combination of piston / cylinder and a combination of May be a power combination.

When a freewheeling mechanism is installed on each crankshaft, the engine is controlled by a program computer monitor system (PCMS) or a power control modular (PCM) to enable alternating crankshaft operation. For example, for 5000 km, the crankshaft A can be operated as the main power train, and then the crankshaft B becomes the idle train. If the crankshaft A is in the idle train state, the crankshaft B can be operated as the main power train until it reaches 5000 km. In this way, wear of the engine in the combination of the two crankshafts becomes uniform, thus extending the life of the engine.

Another advantage of the configuration of the two freewheeling mechanisms is that, for example, when the crankshaft A fails, the vehicle can be driven to the vehicle repair shop using the crankshaft B as a power train, so that the vehicle can be driven. There is no need to tow.

The fourth embodiment with two crankshafts and two freewheeling mechanisms shown in FIGS. 11 and 12 can be operated in the same manner as the third embodiment shown in FIGS. 9 and 10 and described above. The fourth embodiment shown in Figs. 11 and 12 has no self-charging capability since both the pistons and the cylinders are of the same dimensions.
