Description

Technical field

The design solves the simplification of the crank mechanism by converting the drive to one crank pin and compressing the air for fuel combustion.

Background Art

Piston combustion engines, in addition to the turbines used for high power, form the basis of mobile work machines. They are based on the work of piston rings that slide over an oil film. The pressure behind them will push the piston rings against the cylinder wall. It is the most efficient design for compressing less air. Jet machines were used to compress more gas. In the case of reciprocating internal combustion engines, a multi-stage charge air compression is sometimes used.

The crank mechanism is a simple bearing design. Simplification of the crank mechanism is also accomplished by attaching the connecting rods to one crank pin. This design is known as radial engines. However, they are spatially impractical. Therefore, this principle is applied to V-cylinder motors.

The essence of the technical solution

To convert the crankshaft design to one crank pin and perform air compression for fuel combustion, we will do the following.

The four-stroke internal combustion engine has a sliding link equipped with a reinforcing bar, and the slider and the reinforcing bar are rigidly connected to a piston rod which is slidably mounted in the guide, the piston rod being provided with a double-acting engine piston with suction and exhaust valves, one side of the double acting piston being it is formed as a working part and the other side of the double-acting piston is like a pump having a pump suction with a non-return valve and further to a pump outlet, the engine intake manifold being equipped with a turbocharger.

BRIEF DESCRIPTION OF THE DRAWINGS FIG

The accompanying drawings show an embodiment of a four-stroke internal combustion engine as follows:

FIG. 1 shows a link mechanism on one crank pin.

FIG. 2 shows an engine pump with a double-acting piston in an engine cylinder together with a turbocharger.

Examples of technical solutions

The crankshaft and crank shaft designs are shown in Figure 1. This is crank shaft f, crank pin 2 with crank bearing 3. A bearing 4 is supported in the crank bearing 3 by a bearing 5. The link 5 is firmly connected to the piston rod 7 at its ends, and this connection is reinforced by a reinforcing bar 6. Thus, the link 5, the reinforcing bar 6 and the piston rod 7 form a fixed unit which oscillates back and forth according to shaft 1 crank.

The piston rod 7 is slidably mounted in a guide 8 which is in the fixed motor housing 18. The piston rod 7 is provided at its ends with a double-acting piston 10 by means of the fastening 9 of the double-acting piston 10.

There are several H-engines on one crank pin 2.

The cylinder flushing pumps and the fuel burners are performed in a two-stage manner as shown in Figure 2. Double-acting piston 10, which in one side forms the working part and the other in the pump 12. Pump 12 sucks air through the non-return valve 15 via pump suction 19 and pump outlet 17 pushing air into the turbocompressor 13 from which the air flows into the suction

- EN 23151 Ul of the engine line 14 and further through the suction valves to the J4 engine. Exhaust 16 is provided through the exhaust valves to the turbine of the turbocharger 13 according to the designs used.

Industrial use

It is used for high-speed engines and also for heavy-duty internal combustion engines.
