Apparently air-petrol mixture is easier to combust in a wider fuel/air ratio range than for LPG, and also because petrol is liquid at room temperature and pressure (though gives strong fumes), it can stay near the vehicle and potential sources of ignition for far longer than LPG can.
It was a one off article somewhere, I can't even find it again (tried searching just now) - so it may be wrong too.
given the hassles of getting the gas etc. and the lifetime reduction of the engine I would rather go for diesel - for most low people with low annual mileage petrol is the best option, for high mileage guys diesel saves money as well as provides range between refills. |
1) I dont agree with the point that CNG is the safest. Yes, in event of a leak, its relatively more safe, but not the safest.
Why ? Because of the pressure at which it is stored in the vehicle. In car like Waggie, what in case of a high impact rear ending ? The storage apart, CNG is good, but I myself personally think that the CNG cylinder can become a potential bomb. Though not that many cases are reported and I am myself driving CNG cars ( Waggie mainly : thread ) and M800. The cylinder is built for to high quality standards + safety tested too. But I would say that storage makes me think that CNG is definitely not the safest.
2) LPG. Again the storage makes it not the safest.
3) Petrol. Well, we know that petrol explodes. But the storage makes is better than CNG and LPG IMO.
4) Diesel. Yes, here is the safest bet! Purely my opinon, but I too prefer diesel. Its a different thing that we dont have a diesel vehicle at home and I love to revv hard the petrol units, but still from safety point of view, diesel is the best. Not to be stored under higher pressure like LPG and CNG. Wont explode like petrol.
I too read an article blaming Mr. Rick Wagoner for preventing diesel fuel to come into US market. The article was regarding safety point and there it was mentioned that GM had done its best to avoid diesel engines, but diesel is safer than petrol. This article made me read more on this topic. Again, I am not able to find out the exact link to the article. |
