Development of a modification kit

Since standard modification kits in Europe are quite costly, and to make the project more independent from European supliers, a program was made to develop a simple modification kit to modify the FEIDONG Chinese diesel engines of various makes as used in region Bilibiza in the JatroMoz project.


The diesels should be able, after modification, to run trouble free on PPO of sufficient quality from Jatropha, for long periods of time, without having to do major cleaning or maintenance, such as cleaning of injectors or pistons etc. The kit should be simple enough to be applied by engine-amateur technicians like me, with basic tools.

In addition, attention should be paid to controlling the exhaust emissions,  since these diesels are often operated by people nearby, e.g. with maize milling.

The first kits were developed and tried out by Ger Groeneveld both in The Netherlands and in Chimoio Mozambique. (see report Dev_Mod_Kit_dieselsonPPO_fin).
These modification kits did not fulfill the expectations and Niels Ansoe of DAJOLKA developed another type which was applied on 2 Feidong diesel engines in Bilibiza. For an intermediate report see. Development modification kit_state of the art_July 2010. Per december 2010, the two diesel engines were still running without problems  and continuing with an endurance test of 500 hrs running on cooking oil, since no Jatropha PPO was left. Reports on these test by Niels Ansoe will come out soon.

In between in 2008, a meeting with people involved in conversion of engines was held in The Netherlands, see report FACT-Publ_Experiences Conversion Technologies
