Hi Mike, You are right the Stainless steel is not higher than the steel but it is still fairly strong. I recommend no to use any parts in aluminium or copper based. We have found a few years back that copper and alumium are "dissolved" by the fuel under pressure and landing in the nozzle as...

Hi, I use to build flow bench for Delphi and perform test all day as department manager so I may be able to help. The fluids mentioned earlier of the threads are fairly ok, there is a ISO fluid for Diesel that can also be used for petrol test as we proved a few years ago. To obtain...

Hi, The actual common rail runs on 1600 bar, the new generation is 1800 and the future product ( coming 2006/7) will run on 2500 bar. The common rails are normally made out of steel with some special surface finishing. Personally, I used stainless steel for some customized common rails that we...

Hi, I went to a convention a few years ago where most of the German Diesel manufacturer took part. The question was how to go over the 70 hp / litre region. Some people made a lovely presentation on the high performance diesel engine. A few parameters were interesting for the maximum RPM. 1 -...

Pete, I definitely agree with you ! The step made first in California and then in the rest of the USA is fairly drastic and make the changes difficult to implement for the manufacturer. However, the solutions are there, just have to put them together. We have proved in the past that it works...

Hi everyone, I was really suprised to sea that most of the marine engine manufacturer have removed their 2 stroke engine from their program. This has a major impact of small application like jetskis for example : the weight is increasing greatly, same for the fuel consumption. Does any one...

If I remember correctly, the CP3.4 is the common rail pump. Under normal operation, the pump is supply from 280 bar up to 1600 bar. However, the pump is capable of running up to 2000 bar. Depending on the age of the pump, running at 2000 bar ( 200kPa) will definitelly reduce pump life. Recent...

Hi tbuelna, I spoke to the guys at team74. They still have some problem with their ISP and web site but manage to put an email link on their website. I told them that you may want to contact them and are waiting for your email. www.team74.com Good luck

From what I have heard the original patent is now in the hands of mazda. However, a large amount of new patents, special around the rotor sealings have been made in the last few years. I know a company in Germany that is trying to produce a diesel rotary engine. Maybe worth takling to them. I...

Hi tbuelna, The common rail system WILL be designed to drive any type of commaon rail CDI injectors. That means the solenoids one from Bosch, Delphi and Siemens ( most probably the Denso ones too ). This ECU should be ready at the end of the year. You WILL be able to find info on the...

Hi MotorGP, I will try to bring an answer to most of the questions in this thread. What is a "variation in the power supply". If you are mentioning the ECU, this should not be a problem. You have to notice however, that common rail ECU are operating under 13,6V. Below the 11.2V, the watchdog...

Hi don1001, I got into this problem months ago. Bosch, Siemens, Delphi and Denso are not supplying any kind of development ECU to anyone ! ( I know I used to work in R&D in Delphi Diesel). There is however an alternative. I am currently developing a benzin/diesel development ECU for my personal...

Hi emetz564, The Viscor is definitely your choice. It always depend on want you want to do. If you only test quickly an injector ( direct or indirect) that should not be any problems with water or alcohol. However, there is two problems. The first one is that water will tend to oxidise the...
