Description

[Detailed explanation of the invention] The purpose of this invention is to make the engine blazer device compact and high-performance.For this purpose, the blazer chamber is divided into an inlet chamber and an outlet chamber, and the inlet chamber is larger than the same chamber. By making a Breveux hole in the partition wall and closing the Breveux hole with a Blazer valve and energizing it, a large amount of lubricating oil floating in this is separated from the Brochus in the inlet chamber, and further separated in the outlet chamber. It is characterized by

Embodiments of the present invention will be described below with reference to the drawings.

The drawing shows a horizontal water-cooled diesel engine. Basically, a gear case 2 is fixed to the front of an engine body 1, and a radiator 3 and a fuel tank 4 are placed on the left and right sides of the upper surface.

Inside the gear case 2 are a crank gear 5 and an idle gear 6.
, a cam gear 7 that also serves as a valve train and fuel injection, and a pair of balancer gears 8
, and a starter cap 9 are housed therein.

The blow picus leaking from the combustion chamber 10 in the engine body 1 into the crank chamber 11 passes through the communication hole 12, the inside of the gear case 2, and the bypass introduction passage 13, and enters the Blazer installation @14, where the lubricating oil is separated. From there, the air is sucked into a clean air chamber of an air cleaner 16 through a conduit 15.

The detour introduction path 13 is formed in a folded upward slope in the upper left half of the gear case 2, and the blazer device 14 is provided in the upper center of the boundary between the engine model 30 and the gear case 2.

The blazer chamber 17 of the blazer device 14 is divided into an entrance chamber 20 and an exit chamber 21 by peripheral partition walls 18 and rear partition walls 19 at the left and right bottoms.

The inlet chamber 20 extends across the engine model and the gear case, and surrounds the bottom, back, and both left and right sides of the outlet chamber 21.The inlet 22 is opened in the lower half of the left side of the outlet chamber 21. An outlet 23 opens at the center of the upper surface of the outlet chamber 21 .

The peripheral partition wall 18 extends horizontally and is formed integrally with the gear case 2, and the rear partition wall 19 is made of iron plate and is inclined downward in the front and positioned deep toward the exit chamber 21. It is screwed to 18.

A brebou hole 24 is made in the center of the rear partition wall 19,
It is elastically closed and biased by the brevet hole 24 or the blazer valve 25.

The inlet chamber 20 is formed to have a much larger volume than the outlet chamber 21, and the bottom surface of the outlet chamber 21 is formed to be inclined backwardly, and a separation oil return hole 26 is provided at the lower end of this inclination.

There is also a separate oil return hole 27 on the bottom right back wall of the population room 20.
is dawned.

When the rear partition wall 19 is installed with a downward slope as in the above implementation fj4, the height of the rear partition wall 19 is lowered by the slope, and accordingly the outlet chamber 21 and the inlet chamber 20 are lowered. Not only can the height be reduced to make it more compact, but also the outlet chamber 21 can be made smaller and the inlet chamber 20 can be enlarged accordingly.

Since the present invention is configured as described above, it has the following effects.

In other words, when the blow-by gas in the crank chamber enters the inlet chamber of the blazer chamber, the flow is gentle because the inlet chamber is wide, and the lubricating oil floating in the gas is well separated, and what is left behind is separated. The lubricating oil that has passed through the blazer valve is further separated in the exit chamber, so the blow-by gas is sufficiently purified and the blazer functions as a compact and highly capable blazer.

Furthermore, the entrance and exit chambers of this blazer chamber are divided into an entrance and an exit chamber by a rear partition wall and a peripheral partition wall, and the rear partition wall is sloped toward the exit chamber to form a peripheral partition wall. Since the inlet chamber located at the boundary between the engine model and the gear case is formed so as to surround the outlet chamber via both partition walls, the height of the rear partition wall can be lowered by the slope. By widening the inlet chamber and integrating it across the boundary, the blazer chamber can be made smaller and the separation performance can be increased.

Furthermore, since the blazer chamber is formed across the boundary between the engine model and the gear case, it is easy to process and can be implemented at low cost.

Moreover, since the outlet chamber is formed narrowly, when the crank chamber is under negative pressure while the piston is rising, even a small amount of gas is sucked back into the outlet chamber, which tends to create a large negative pressure. The lubricating oil is sucked back into the inlet chamber through the return hole, and in this respect as well, the compact and highly capable blazer function is achieved.
