Problems with valves with auto lpg/cng

[blackwolf76]

What color were the candles rossiccie, the car was the first to open the head that the system was installed under

Plant brc installed at the new car, the valves are all red as obvious a sign of too high temperature in the combustion chamber. The spark plugs are good given that they have replaced just before bring me the car.

Anyway, the car was left with very little compression, then off to a minimum and performance pitiful...

Bad calibration of lpg also check the catalytic converter with the probes

my installer on the cars of the latest generation is designed to be a dispenser of oil speciifco to lubricate the valve seats!!I believe that the best prevention is sgasare the car after consumption of a full gas or petrol fuel petrol!!

The dispenser of oil should theoretically do what you say but really? send the car to the mixture .... The problem with many distributors even sell the system do all they can also tune the cars with standard maps and here are the results ..... From the same car the map can change, and then also the carburation and then we remember that we are working with 150 octane cold and hot with 100 octane

ergiaguaro why? there would be this change in octane between cold & hot?

[ergiaguaro]

The gpl ? in the liquid phase at -4 degrees with about 12 bar, and the reducer to the task to transform the gaseous phase through the water of the engine ....... in fact, the problem is solved with a system in the liquid phase see vialle or prins +20 hp, but it is not cheap

I see more? as a change of the fuel mixture,
and not numbers of octane..
it is clear that a cold liquid has a different behavior..
but the octane is calculated on the basis of the point of detonation of the fuel..
and dir? pi? there are only two test benches all over the world and are found in the USA,
and it is a motor with a dimension to vary the compression and advance and other various tests that there is a way to test the behavior of the fuel..
and I think the evidence you should do is always to operating temperatures..
as an optimum fuel should be made of a warm engine, no? maybe you make corrections to cold temperature, but what we interrasse and 90?..

[ergiaguaro]

In fact, the control unit of the gpl manages the fuel mixture based on the temperature, but then you have to deal with the strategy of that of gasoline ? different in the pi? if the calibration is incorrect, there are other problems

lancia kappa engine 2.0 turbo 5valvole.. exhaust valve burned 150kkm; the rig was an icom in the liquid phase.
the idea that to do as much of the quality? of the facility and especially the calibration of the latter

[ergiaguaro]

That type of system does not have a true control unit is therefore not manageable
