If drive the car on the propane-butan gas, and have the usual carburetor can build in cut-off valve with managing electronics. Ask yourselves:
Why build in CUT-OFF device ?
Building in achieve:
Decrease of of fuel around 7.5 % i.e. cash savings
Prolongation of autonomy of drive on the gas also for 7.5 % (more rarely the filling of gas)
The smaller usage brakes because brake the motor
The larger stability drives at retardations on the slippery road (good motor breaking)
Decrease polution decrease of average consumption
Possibility of the easy defensive drive release accelerator pedal starts good motor breaking
Otplativost CUT-OFF of device in the similar term as well as for the rest gas installations
The large profitability investments because of the long life cycle of device
How works CUT-OFF valve and driver?
CUT- OFF device work simple. During the every stopping or lowerings downhill when dismissed the accelerator pedal (when has not been pulled the choke), managing electronics eliminate the flow of gas towards carburator decreasingly him on the minimal value as long as number turns of motors not did come below the given border number turn (1200 to 2000 turn in the minute depending upon the minimal flow of gas and motor) or while again does not shrink the accelerator pedal. Thus saves the fuel and improves motor breaking . The minimal flow of gas at the shut-off valve adapts on the valve. Testing of device on LADI Nivi has shown the saving from 7.5 to 10 % by the drive city and open road. The tested vehicle has the set device on 1500 turn per minute.
Savings of fuels bases on the exploitation kinetic and potential energies drive beside the minimal of gas. Thus every breaking motor turn into the saving of fuels and brakes, and the every entrance in the bend, where has needed little to step on the brakes, becomes the simple, safer (because the motor breaking is the one kind ABS-and) and more economical. Needs only on time release accelerator pedal.
Importantly notices that savings of fuels functions in fact and on the enlargement of autonomy of movement one fillings of gases for also 7.5 to 10 %. For example: if one fuel tanks made 700km then with built-in CUT-OFF device make from 750 to the 770 km. Of course that the profitability of appliance needs does not look at along the decrease than and along the lengthening of passed kilometers. So only on the 450 km of the passed on the gas instead of on the gasoline were able save 30 % the price of device.
The shown appliance uses on motors with the usual carburator and possibly he builds in subsequently (on already existing the gas device).

Price of set (the appliance + LANDI valve with the built-in adjusting-screw of minimal flow of gas + the instruction for the connecting) is the 471 HRK (the 63 euro). At orderings cash on delivery needs add and postal costs.
Warning: BRC valve for the vaporized gas is not enough quality for this usage this will work only 2 month properly. After this starts jam in the open state. Reason is in the nonexistence of final processing on the tolerance of assembled parts of cob and in the diversity of cones of cob and tolerances of assembled parts!!! We use old LANDI valve who work error free. New Landi Renzo valve has the same structure as well as old these enough quality for often switch on and go off.
Possibility of different usage:
The precise comparator frequencies (the necessary calculated element)
Complex on order with different characteristics
