Abstract

An indirect type seamless energy-saving piston ring comprises a piston ring. A convex gas check plate is arranged at one end of the piston ring, a left gas check plate and a right gas check plate are arranged at the other end of the piston ring, and a groove matched with the convex gas check plate is formed between the left gas check plate and the right gas check plate. During use, the convex gas check plate can exactly matched with the groove, resulting in over 300 h operating time more than the operating time of a common piston ring. During operation, if the compressed gas and combustion gas in a cylinder leak when passing through the indirect type seamless energy-saving piston ring, the staggered gas check plates are matched with the groove wall of the piston ring to stop the leakage.

Description

Indirection type seamless energy-saving piston ring

Technical field

The utility model belongs to a kind of piston ring, relates in particular to a kind of indirection type piston ring.

Background technique

Common in the market piston ring following situation can occur under the wear limit state: engine power descends, and starts difficulty; Black smoke is continuous after the load-carrying, and it is insufficient to burn, and fuel consumption is big, and traction power is little.

The model utility content

Technical problem to be solved in the utility model provides a kind of indirection type seamless energy-saving piston ring, thereby improves engine operation efficient, and is the prolonging overhaul time, energy-saving and cost-reducing.

In order to achieve the above object by the following technical solutions: comprise piston ring, be provided with the convex plate of holding one's breath at an end of piston ring, being provided with left side plate and the right side plate of holding one's breath of holding one's breath at the other end of piston ring, holds one's breath and forms in the middle of plate and the right plate of holding one's breath and the convex groove that plate matches of holding one's breath in a left side.

Described groove is the Three way type groove.

The described convex precision-fit between plate and the groove of holding one's breath.

The utility model in use, convex is held one's breath plate and groove can precision-fit, can the multiplex (MUX) do more than 300 hours than pot type piston ring, when work, pressurized gas in the cylinder and combustion gas when indirection type seamless energy-saving piston ring gap leakage loss, hold one's breath plate and the piston ring cell wall that the is interlocked blocking-up that matches.

With normal bavin single cylinder 1100 motors, do 10 experiments continuously, each pot type piston ring fuel oil 500g, average stroke 31.5 city; The utility model, each fuel oil 500g, average stroke 36.7 city.According to the experiment estimation, the every overhaul of motor was once worked 1500 hours approximately, saved 400～500Kg oil at least.

In the experiment, 3mm is removed in one end-grain cutting of pot type piston ring, motor can't start; 3mm is removed in the utility model one end-grain cutting, start normal.

Embodiment

Shown in Fig. 1～4, a kind of indirection type seamless energy-saving piston ring, comprise piston ring 1, be provided with the convex plate 2 of holding one's breath at an end of piston ring, the hold one's breath length of plate of convex is 5mm, be provided with left side plate 4a and the right side plate 4b that holds one's breath that holds one's breath at the other end of piston ring, hold one's breath and form Three way type groove 3 in the middle of the plate in hold one's breath plate and the right side, a left side, the hold one's breath length of plate and the right plate of holding one's breath of a left side is respectively 5mm, Three way type groove 3 and convex plate 2 precision-fit of holding one's breath, the hold one's breath thickness degree of plate projection of convex preferably accounts for 2/3rds of piston ring total thickness, and the hold one's breath thickness of plate and the right plate of holding one's breath of a corresponding left side is 2/3rds of piston ring total thickness.

Convex the hold one's breath length of plate and the right plate of holding one's breath of plate, a left side of holding one's breath can change with the change of cylinder sleeve, piston, piston ring and Environmental Conditions.

Claims
