Embodiment

[0012] Such as figure 1 As shown, a pneumatic oil limiting device for a mixed-combustion engine includes a connecting seat 1 and a cylinder connected to the connecting seat 1; the cylinder includes a cylinder block 6 and a piston 7, and the cylinder block 6 is provided with a piston limit retaining ring 8, and the piston limit The function of the retaining ring 8 is to adjust the stroke of the piston 7 by cooperating with the limit step 9 on the piston rod. The outer wall of the cylinder body 6 is provided with an adjustment thread 3. The function of the adjustment thread 3 is to cooperate with the lock nut 4 to adjust the cylinder. The distance between the connecting seat 1 and the cylinder body 6 is provided with an air nozzle 12. The function of the air nozzle 12 is to realize the air intake inside the cylinder body to push the piston 7 to run. The piston rod of the piston 7 is provided with a limit step 9, and the piston 7 The piston rod located in the cylinder body 6 is p...

Abstract

The invention relates to an oil supply amount limiter device of a diesel oil and natural gas mixed firing engine. The device comprises a connecting seat and an air cylinder connected with the connecting seat. The air cylinder comprises a cylinder body and a piston, a piston limiting check ring is arranged in the cylinder body, adjusting threads are arranged on the outer wall of the cylinder body, an air tap is arranged at one end of the cylinder body, a limiting step is arranged on a piston rod of the piston, the position, arranged in the cylinder body, of the piston rod of the piston is sleeved with a piston resetting spring, one end of the piston resetting spring is fixed to the piston limiting check ring, and the other end of the piston resetting spring is fixed to the piston. The connecting seat is of a through cavity, a piston locating hole supporting the piston rod is formed in the connecting seat, one end of the connecting seat is provided with outer threads and is connected with an engine oil pump in a matched mode, and the other end of the connecting seat is provided with inner threads and is connected with the outer threads on the outer wall of the cylinder body in a matched mode. The device is a diesel oil and natural gas engine oil supply amount limiting device, under the mixed firing mode, due to the fact that the limiting step and the resetting spring are arranged on the piston rod of the piston, the stroke of the piston is effectively limited, and the economical running requirement of the engine is met.

Description

technical field [0001] The invention relates to the field of a mechanical compression ignition type engine oil supply limiting device, in particular to a fuel supply limiter for a diesel and natural gas mixed combustion engine. Background technique [0002] In recent years, the engine control technology of diesel and natural gas mixed combustion has become more and more mature. During the operation of this kind of engine, precise air supply control is particularly important. At present, a real-time fuel consumption is the main control parameter, and it is used to supply air to the diesel and natural gas mixed combustion engine. Stable, but in the use of engines with mechanical fuel pumps, it is easy to cause excessive oil supply and excessive gas distribution to the engine, which will cause fuel waste and even damage the engine. In the prior art, in order to ensure that the fuel supply of the engine is not greater than the required value in the co-combustion mode, oil limita...
