O.K. Patrick one at a time.
The actual diesel injector is inserted with direct contact into the cylinder head and protuding in some way into the hot combustion chamber or a combustion chamber connected pre-chamber. At normal diesel engine idle not much engine cylinder head heat produced and not much cooling diesel fuel flow needed to suppy. High engine load on deisel; then high volumn of diesel fuel flow supplied to the injector to fuel the engine and injector heat remove. Low “idle” amounts of diesel injector flowing with HOT fully loaded cylinder head temperatures documented DID cause problems with the 70’s Swedes projects, the 80’s,90’s in India projects. They had to modify to incease the actual injector bypassed fuel flows to help cool the injectors to reduce accelerated injector mechanical wear, heat warpage and seals failures.
The actual diesel engine companies with professional paid engineers measured THIS problem challenge along with other found needed adaptive durabilty/cost factors and all decided to just ALL go with spark converted compression adapted engines when they were direct engine system suppliers for producer gas systems. Thier name/reputations were on the line.
Woodgas most certainly CAN be turbocharge boosted. Noboby done it has complained about increased impellor/turbine wear.
You have any old many hours gasoline or diesel turbo’s engines around in some working application? Ones that have worn the turbo shaft seals now constantly drooling oil out the air in snorkel? OK with the engine running and loaded into turbo boost range restict the air in side enough to produce some negative pressure on the inlet side. Now watch how much oil you will suck out of those turbo bearings! IF a diesel careful of engine oil fueled speed run-a-way. Have an inlet strangle plate handy!
Engine sucking a gasifier system you WILL be doing this inlet side negative pressure operating 100% of the time or you will not be getting any woodgas produced to the turbo to go to the engine. So as the Finn Vesa Makinen here on the DOW posted up from direct woodgasing experiences you need a turbo that has oil bearing seals of a type, unworn, that CAN take this woodgas system negetive pressure on the inlet side.
Now since obviously I, both VesaM’s, JonathanL, WayneK, and a whole bunch of other Sweeds, other Finns and India fellows along with 7 mainline very diesel engine capable, engine manufacturers are so full of it (fecal matter) saying these things then it should be no problem for the Trillions/Singapore people to supply you with the direct independent contact info of 3-4 actual in the real world user installed systems in current use with accululated 500-5000 loaded hours fueling diesels so THESE independent satisfied system users can directly sing thier praises.
I’d really like to hear about these actual in the real world satisfied pilot fuel diesel engine woodgas users. Please ask them for thier engine types: 2-stoke, 4-stroke; IDI, DI; natural aspirated, forced induction; fuel injection type - rotory pump distributed, inline pump, individual pumped, unit rocker arm type or electronic common rail.
Then we can sort out which of the many actual diesel system types out there that these real users are satisfied woodgasing with.
