Common rail has been out a lot longer than 1995. Its the same principles as a petrol injected holden , ford , etc except the fuel pump is mechanical like a bosch cp3 & higher pressure , do u drive a carby engine or fuel injected as family car ?Commonrail term is exactly the same as petrol fed injectors , it has a high pressre common fuel rail that feeds injectors , most people who get a jap engine import engine say a 2jzte,1uzfe for example will run an aftermarket engine management . In nz theres link as u know , in oz theres haltech , ems ,wolf/aem , etc . europe has autronic ,et,etc.
Theres heaps of fuel only aftermarket engine management , they are normally 1/2 price of fuel/ignition units , 2nd hand ones are few hundred $$ .plus theres performance diesel ones like zeus,etc. Have a read of the latest diesel power magazine , shows how simple they are , common sense really .
With aftermarket engine management you can run different settings at a flick of a switch ,eg economy , towing , power/performace , that adjust fueling , timing , wastegate actuation , blow off valve ,Thermo fans , water spray ,, engine temp , etc, etc soon.be able to flush the toilet too with no hands lol. how do you do that on an injection pump ?
Plus alot ecu/engine management systems now are in waterproof housing , alot like cummins , cat ,etc are bolted side of the block. Its just the next step , like when diesels were naturaly.aspirated & then they put turbos on them , alot of old school people dont trust turbos as its not what they know , wasnt in thier generation , like some people are against EFI diesel engines ( do u use a remote control for ur plasma/lcd tv or do u get up & change channels by hand everytime ?) commonrail sounds different than electronic fuel injection , its for marketing reason , it sounds totally different so it must be a new thing NOT !!!
