Hello
There may be some hope on vehicles whose Lambda sensor really works.
In my space, the intake manifolds are rectangular and profiled with a wider curvature; I do not see where I could place them ... Moreover, the injector seems to be directly at the top of the cylinders, do you think that the turbulator could bring something in this case?
Pascal
First of all, it's having a quality lambda sensor that responds quickly and works well. (easy to change)
Have candles and wire in good order,
Have a clean gasoline filter (the injection pressure should not be decreased especially multipoint injection.)
then do road consumption tests before making some modifications.
For the engine with which I have the best performance, a 6-liter V3,8 from GM, it is a multi-point the inlets in the cylinder head are rectangular even narrow, the injectors are placed directly above the intake valve, the generator cyclone is placed directly behind the throttle in a thin steel tube, 3 "(75mm) long, carried in the aluminum tubing was too narrow. The turbine must be securely locked in place so as not to She turns.
The Lambda probe is in operation only when the engine has reached a certain temperature after starting, it is put into operation if the throttle is slightly open (detected by the potentiometer at the end of the throttle)
To hope to have a results with a cyclone generator, it is necessary that the system is in loop and that the lambda probe corrects.
The lambda probe makes an adjustment to have the least possible nox not the most economical but it is very close, it controls 0,45 volt is a ratio of 14,7 / 1 but the most economic would be 18 / 1 The Lambda probes are mainly balanced so that the catalyst is functional, at 18 / 1 there is nox
In a city driving the loop is often open ie the engine runs on basic values, rich, and we use the air flow mass, as well as the position of the throttle and a little the engine and air temperatures swallowed , according to the manufacturers to drive the injection, so nothing to win under these conditions.
The idle injection engine has a pitiful performance, worse than a well-fitting carburetor engine!
For the handyman who wants to make such a turbine, the difficulty is to weld the 6 blades together, I always start with a double blade then I weld the others, and I finished the adjustment to the file so that it overlaps well and that tight between the tubing.
