On the basis of the development of the VR6, a Diesel version was tested early on. The turbocharged two-valve engine with a displacement of 2.4 liters, seven main bearing crankshaft and a distributor injection pump came to being at first with a swirl chamber process (no direct injection yet). The engine exhibited here, however, was never installed in a vehicle. It served only as a "test bench unit".Auf Basis des in der Entwicklung befindlichen VR6 würde bereits früh eine Diesel-Version erprobt. Der aufgeladene Zweiventilmotor mit 2,4 Liter Hubraum, siebenfach gelagerter Kurbelwelle und Verteilereinspritzpumpe entstand erst nach Wirbelkammerverfahren (noch keine Direkteinspritzung). Der hier ausgestellete Motor war indes nie in ein Fahrzeug eingebaut. Er diente lediglich als "Prüfstandaggregat".
Anfang der 90er-Jahre wurden ähnliche Motoren mit 2,8 Liter Hubraum in TDI-Konfiguration versuchsweise in den Golf und den Bus T4 installiert. Für den Einsatz im Passat 6 vorgesehen, aber dann verworfen war ein 3.0 Liter-VR6 TDI mit ca. 230 PS un 650 Nm.
Yeah one guy i know has an audi 80 1.6TD with a power steering and an automatic airconditioning. I joked the other day that his airconditioning has more electronics then the engine. I kinda like the sound of old diesel engines.I have seen the other day a weird little engine on a vw polo, 1.4 l IDI with the injector pump fitted on the gearbox side as per the t4 2.5 tdi...Never seen one before, i have pictures but i don't use a hosting site...it ran great, a bit clackety-clack but nice and stable ! The old boy that has it is also driving from time to time an very tidy old audi 80 with the 1.6 Td engine and also a t3 van with a nice 1.9Td in it ! I offered to buy the audi but he wouldn't budge...
Chill, CHill! I know that, I should have been more clear to state that someone would propose such a project in this thread! The last posts of this sort seem to be at least 5 years old!There are endless posts on building a vr6 project...just all prior to these pix which are only very recently posted.
just stuff the injectors in the plug holes, head's already flat on a VR iircChill, CHill! I know that, I should have been more clear to state that someone would propose such a project in this thread! The last posts of this sort seem to be at least 5 years old!
With how far we've come along in the aftermarket, it's no longer a major barrier to have a set of custom pistons and high pressure fuel rails made. We can even have a small run of custom cylinder heads reverse engineered and cast! Common rail injection with a stand-alone ECU and one of many CP3 HPFP options would seem to be the way to go.
Or it might be cheaper and easier just to ask the VW Museum to sell its test mule above for the sake of science!
I didn't look very closely but yes, the head is completely different from the gasser 12v vr6. Still cross flow but the ports look like they're stacked to make room for the injectors.Chill, CHill!
