TB42 turbo
Hi, I have just brought a patrol with a tb42 carb dual fuel. the motor is still quite fresh but the economy is around 20l/100km - costly.
what i am thinking is to increace the economy i can bolt on a turbo from the td42 and run it straight through the carb with a view to having a lean mix. my question is this; if i fit a WI system that kicks in at say 0.3bar will i eliminate any pre detonation? (I would prefer to run just one fuel (i.e. remove the gas or petrol) but that fuel could be petrol, ethanol or lpg - i just want to save some fuel) thanks in advance tom |

Re: TB42 turbo
Increasing the compression ratio of the engine will certainly improve the efficiency of the engine. In your case, adding a turbo.
If you can keep engine knock in control with water injection and at the same time a leaner mixture and more advanced timing, you will gain economy for sure.

Re: TB42 turbo
Thanks for your reply Richard.
Whould you have a guess at a boost level? its a 4.2 petrol carb engine - what nozzle size would you start out with? ulp mj/l 34.8 $/l 1.41 $/mj 0.040 ethanol mj/l 21.2 $/l 1.39 $/mj 0.065 lpg mj/l 25.3 $/l 0.7 $/mj 0.027 i knocked up the above table to compare fuels and inteperate it to mean lpg would be best for economy. thanks Last edited by stencilman; 27-04-2014 at 12:16 AM. |
