river porter christoper yohan has already driven about 12000 kilometers with his little s.u.v. hassle free. you can't tell the difference from a gas engine. to see how to run as one leader 3 cylinder engine produces 90 horsepower and with an average gas consumption of 4.2 kilograms of gas per 100 kilometers it's quite a logical. 4.2 kilograms of gas costing a total of 4 year olds $0.50 in germany still emit 123 grams of c o 2. but there's an almost total reduction in particulates and nitric oxide. no question natural gas is very environmentally friendly the problem is the price $1.00 kilo costs in germany in 4 years now around one rule but the price of diesel and petrol so much so that it's no relevant saving by using that for gas costs similar to a diesel locomotive. and there's another old and persistent disadvantage despite being stored at high pressure natural gas takes up a lot of space. the tanks are large and expensive. yet the same can only take 15 kilograms. and the bigger to. thank you means a smaller chunk. the only problem of the c.f.r. or not t g i is not the limit
