Information by the company MAN B&W Diesel AG
Here you can find the information brochure "Green Power - From Diesel Engines Burning Biological Oils and Recycled Fat".
This is an excellent report on the use of Biofuels and follows an in-depth study which covers the use of PPO in thier larger engines.
The report mentions that engine manufacturers claim,
" Lower quality fuels such as raw vegetable oils have been reported as simply not acceptable for use in any concentration: in some high-speed engines these oils do not burn completely and finally cause engine failure by leaving deposits on the injectors and in the combustion chamber."
Their report focuses in on medium bore engines and found none of these problems.
The paper presents MAN B&W Diesel group’s advances in the field of renewable energy from workshop and field testing to commercial operation of medium-speed Diesel engines with a variety of liquid biofuels including biological oils and recycled fat.
In addition to this it is interesting to note that Deutz Tracctor have given the green light for all their Agrotron range
