Gear type diesel engine

Abstract

A gear type diesel engine relates to a diesel engine, and comprises an engine case, a rotor type piston ball, a rotor type air cylinder, a transmission gear set and an air supercharging device, wherein the rotor type piston ball and the rotor type air cylinder are positioned in the engine case; the transmission gear set and the air supercharging device are positioned on the outer side of the engine case; the rotor type piston ball and the rotor type air cylinder are meshed with each other, and mounted in the engine case through gear shafts; one end of each gear shaft extends out of the engine case and is connected with the transmission gear set; the air supercharging device is mounted on the outer side of the engine case; a flue gas exhaust pipe, a flue oil conveying pipe and an air inlet pipe which are communicated with the rotor type air cylinder are mounted on the engine case; an air inlet end of the air inlet pipe is connected with the air supercharging device. The gear type diesel engine has the advantages that the four strokes of air suction, compression, outburst and exhaust are completed during the process that the rotor type piston ball and the rotor type air cylinder are continuously meshed and separated, the operation is more stable, the noise is low, the structure is simple, the self weight is reduced, and the manufacturing difficulty and the manufacturing cost of the diesel engine are reduced.

Description

Technical field [0001] The invention relates to a diesel engine, in particular to a gear type diesel engine. Background technique [0002] Internal combustion engines are widely used in automobiles, ships, machinery and other fields. Compared with gasoline engines, diesel engines have the advantages of high compression ratio, high fuel efficiency, and simple structure, but they also have their own shortcomings, mainly in the following aspects: [0003] (1) Loud working noise: [0004] Compared with gasoline engines, diesel engines have a higher compression ratio and therefore higher fuel efficiency. However, the maximum pressure in the cylinders of diesel engines is much higher than that of gasoline engines of the same power when working, and the momentum at the end of each stroke is greater. Therefore, its working noise is also relatively large. [0005] (2) Self-weight and heavy body: [0006] Due to the high pressure in the cylinder of the diesel engine, the mechanical parts are su...

AI Technical Summary

Problems solved by technology

[0003] (1) Loud working noise:

[0004] Compared with the gasoline engine, the diesel engine has a higher compression ratio, so it has higher fuel efficiency, but the maximum pressure in the cylinder of the diesel engine is much higher than that of the gasoline engine of the same power when the diesel engine is working, and the impulse force at the end of each stroke is greater. Therefore, its working noise is also relatively large

[0005] (2) The self-heavy body is bulky:

[0007] (3) The manufacturing process requires high processing difficulty:

[0008] Some parts of the diesel engine have higher machining accuracy, especially the fuel injection pump and injector of the diesel engine have higher precision requirements, and the machining is more difficult, which makes the manufacturing cost higher than that of the gasoline engine.
