I’m looking for new idees to solve the current problems. The first time Frits shows his idea, which I already did one month ffrits. Recently I bought a new digital scope unfortunately without the calculating mode but with the possibility to attach a memory stick The frozen measuring picture can be put on the stick and the via the computer be transferred to the calculating part of the excel program to show the area under the curve.

Since you are just talking about different fuels and compression ratios anyway, I have got a question. More modern, smaller, lighter Japanese coils could never match the power of the old heavy Bosch units.

Been on Kiwi site a few times where you and Wob keep us all on the correct path. The last alinea I wrote 16th of March.

In any case the engine likes it, but the spark plug does not; this ‘plasma’ ignition eats plug electrodes for breakfast. A bridge port like in a Honda RS has two disadvantages. Bob van der Zijden Nombre de messages: Boy, that required some imaginative reading!

It would just stop firing at about We frist everything we could to make the engine rev with a 0,55 squish. Institute of TwoStrokes Nombre de messages: Althought this system overmxrs produce more power than the current way, it still is the question, if in practice this will be prooven. It is oil and heat resistant, and good for oilseals. Regarding your remark about seizures: It is a reusable material that can be melted in the microwave and then poured for molding.

Frits Overmars Expansion Chamber aka FOS exhaust concept

Frits Overmars Nombre de messages: Certain people on this forum do know about this project but never dare to mention it But there is also a cheaper way: I didn’t know the above photo, but my guess: Fritts only the cross-section and the radii, especially the inner radius, but also the duct length plays a role. Page 1 sur Won quite a few races with it.

I see the MSD discontinued has a primary resistance of 0. Listened to the full length of In a gadda da vida 17 ovefmars fantastic, I knew the music buy not the title. The engine will officially have been a Piovaticci, but in reality it still was a 50 cc Jamathi, built in Holland and taken to Italy when Jan and Martin got their works contract with Piovaticci.

The overmarx you formulated that question gave me a headache Manuel. It is an aircooled 50cc Kreidler engine with 4 exhaustports and 2 exhaustpipes each pipe with 2ports10 transfers en one 30mm rotary valve inlet system.

A smaller crank web diameter means less material around the big end hole, a weaker press fit and a flabbier crankshaft. Page 9 sur This result in a flow of the gasses in the direction of the chamber, while pressing the last burned gasses to the edge of the cylinder. The same thing is with Malossi crankshaft for Piaggio crankcase which has 2 mm less in webs diameter than original one to fit also older crankase so that means 4mm space between webs and crankcase like in your case and the power is not lower, but the webs on Malossi are fuller and crankshaft is heavier.

Now, however, I read the comments once again I found myself on some comments, not good or even not at all have responded and still someone who I consider high in 2t developments.

My thoughts were that inertia dyno just doesn’t get air cooled engines up to a stable temp, hence adding the load would improve things.

So, ovetmars there also a limit? The FST system with 4 exhausts is occupied with 2 full exhaustpipes, has 50cc and is dedicated for racing on 2 ovrrmars.

Then the complete exhaust system was removed and carburation and ignition were fritx re-opimized for the pipe-less engine. Howard Gifford Nombre de messages: But now it seems to be a working system I have to change my plans. This is mainly used to prevent rings sticking, catching in ext port, and ring stopper pin damage. This step will act as an anti-reverse treshold when the disc is almost closing and the flow may try to reverse from the crankcase to the outside world.

It is some of the best reading on the planet and is like an encyclopedia of information about real world 2 stroke performance.

Thus, cost reduction is an important object. The compression ring of the present invention has a composition comprising by mass 0. The averaged values of the thermal sag resistance were shown in Table 2. Because stress is concentrated on the spheroidal cementite, gg is considered as a factor of decreasing the mechanical properties of steel wires.

Steel having good wear resistance. The relation between the thermal conductivity of the steel and the total amount of alloying elements is shown in FIG. About 30 min per 25 mm of ruling section is to be provided and then the steels should be immediately quenched jjis oil. To this end, it is most effective to dissipate the heat of pistons to cooled cylinder walls via compression rings. Image analysis on an enlarged photomicrograph of this structure revealed that the spheroidal cementite had an average particle size of 0.

An object of the present invention is to provide a compression ring having excellent thermal conductivity and thermal sag resistance as well as good price competitiveness, which can be used in a high-thermal-load environment in high-compression-ratio engines, and a method for producing such a compression ring. The production method of the present invention using mass-produced steel defined by JIS contributes to cost reduction.

To lower the temperature of combustion chamber walls, it is effective to lower the temperature of piston crown surfaces. Of course, a nitriding treatment is also usable.

A method for producing a compression ring consisting of a composition consisting of by mass 0. A compression ring consisting of a composition consisting of by mass 0.


Japanese Office Action, dated Feb. Search Expert Search Quick Search. Accordingly, the spheroidizing annealing is conducted preferably in place of the second patenting treatment. In Example 3 with a manganese phosphate coating, the difference of a substrate did not change the microwelding resistance jiis. However, the thermal sag resistance is actually deteriorated as the amounts of alloying elements decrease, making impossible use for compression rings in a high-thermal-load environment.

SUP9A steel stockholders and suppliers from china. Materials with smaller amounts of alloying elements have higher thermal conductivities.

Measurement of Thermal Conductivity In Examples 1, 4 and 5, and Comparative Examples 1, 2 and 5, the thermal conductivity was measured by a laser flash method. In a scanning electron photomicrograph of FIG.

The above composition is basically a steel composition identified by the material number of SUP10 according to JIS Ghaving high thermal conductivity because of a small total amount of jie elements, though it comprises small amounts of Cr and V. Bar or wire product for use in cold forging and method for producing the same.

The test was conducted 5 times in each of Examples 1, 4 and 5, and Comparative Examples 1, nis and 5, and the measured results were averaged. Decarburization resistance is also good big cross section of various important spring, such as automobile, locomotive, large plate spring, spring, etc. The spheroidal cementite preferably has an average particle size of 0. Each rectangular cross-sectioned wire 8401 1. In the present invention, the 481 cementite has an average particle size of 0.

The Formation of Martensite. To provide a price-competitive compression ring having excellent thermal conductivity and thermal sag resistance, which can be used in a high-thermal-load environment of high-compression-ratio engines, steel identified by the material number of SUP10 in JIS Gwhich contains small amounts of alloying elements, is used, and a piston ring wire is annealed before an oil-tempering treatment such that spheroidal cementite having an average particle size of 0.

The method of the present invention for producing a compression ring having a composition comprising by mass 0. Ground Spring Steel bar can be supplied, providing a quality precision finished bar to tight tolerances.

The results are shown in Table 2 and FIG. The facts that the amount of Si, a solution-strengthening element, is particularly smaller in SUP10 used in the present invention than in Si—Cr steel, 4081 that spheroidal cementite is formed, appear to contribute to the improvement of thermal conductivity by reducing the solid solution of C. Because spheroidal cementite having a predetermined particle size, which is formed by the spheroidizing annealing, is influenced by subsequent heat treatments and affects subsequent drawing, the spheroidizing annealing is preferably conducted immediately before the last oil-tempering treatment.

SUP9A steels, Highlight the advantage is good hardenability, another hot working performance, comprehensive mechanical properties. Though the spheroidizing annealing may be conducted in place of the first patenting treatment for higher productivity, attention should be paid to provide the spheroidal cementite with particle sizes in a predetermined range.

Because the heat treatment temperature and time differ depending on the size of a heat treatment furnace and the cross section areas of items to be treated, they should be adjusted such that the spheroidal cementite has preferred particle size and area ratio. The number of cycles at that time was used to evaluate the life of the ring.
