I have installed a 12kg CNG cylinder in my Ritz, all my other cars have a 14kg cylinder. You can install 8, 10, 12 or 14kg cylinders.
The reason I choose the 12kg cylinder for my Ritz was that the spare was easily fixed in the remaining space.
My car runs for about 125-150 km on a single tank of CNG using 100% a/c & 100% city, the variation occurs due to idling with the a/c on. Quote:

I've heard sequnatial kits have like close to zero compromise on performance.
We have a company fitted Alto CNG and the spare wheel sits in its original position below the cylinder and in case of a flat we just need to pull the rear seat down and pull out the spare wheel i wonder why its not the same in yours. | Quote:

YOGII- no sir, our installer doesn't install the sequential kits. rest maglev would enlighten us! | Quote:

Also the engine will be more happy as the gas and air are not mixed as in a Lambda system. Switching between petrol/cng can never be noticed in an SI kit. Don't know how much is the cost of an SI kit for CNG, for LPG it costs around 38-40K. Factory fitted LPG cars like Spark, Xeta LPG and Santro eco runs on SI kits where Maruti relies on Lambda systems for their Duos. | Quote:

The only caveats are that SI kits are more difficult to install (and even remove), they require professional installation and they are more than double the cost. SI CNG kits with a good installation are upwards 60k. I went for a normal lovato kit and it costed me 28k. My running is 1400km per month and it shall take me 9 months to recover the costs. So far, I've recovered half the costs of the kit.
One odd benefit is that these normal systems are like your carburetor systems in cars. So when you take your foot off the accelerator, the car coasts and slowly comes to a halt (the EFI on the Maruti Alto is very jerky). |
The Sequential Injection kits can deliver amazing performance, but they are permanent in nature. One cannot get them removed as the installation of such kits requires drilling holes in the cylinder head. If done incorrectly then you practically need a brand new engine, so it isn't worth the risk or cost. Finding an expert for installation is also difficult.
The spare in my car cannot be removed by folding the seats as the design of the spare wheel well does not permit this.
The Chevrolet Aveo comes with a factory installed Sequential Injection CNG kit. |
