Compressed Natural Gas (CNG) is a preferred fuel by some fleets for its lower fuel cost and environmental emission savings. In this video, I'll show you the similarities and differences of CNG to gasoline and diesel, as well as how the refueling infrastructure for CNG operates.

Wow what an awesome video. For a curious mechanic, this couldn't be more perfect of a video
Glad you liked it!
great video mann, i got enough knowledge for cng. this fuel is too common in my country,but i didn't know how it is refuelled,nice job
Glad it was helpful!
Can you do a video on LNG v CNG car engines, or Hydrogen v LNG &/or CNG? No one has ever done it. You could show clearly, for the first time, the comparisons of cost/tank capacity/mileage/BHP/pros/cons/fuel cost/ease of engine conversion (if appropriate) or cost per engine etc. I think you're the man for the mission!
For LNG, there isn’t a light-duty engine spec, as that sits on the heavy-duty side. But, natural gas engines are the same between LNG and CNG; LNG simply warms to a gaseous state as it enters the engine, having the same ignition and octane as CNG. 😊
This was very interesting thank you for sharing
You bet!
What about ignition timing, optimal mixture, camshaft timing, who deals with these changes ? the customer ? does the vehicle get inspected on a Dyno before and after installation ?
Since CNG has a different octane vs. gasoline, it does require a swap in the engine computer. CNG is very rarely seen as an individual vehicle - far more popular with fleet vehicles, especially in heavier applications. Indeed, there's a network of mechanic shops that are certified to operate on CNG, which does require separate training.
Time to get this on the road again with these fuel prices 🤣🤣
To be honest - this video was shot a while back when CNG upfits were more available. EVs have ultimately become the better alternative for gasoline.
I'd feel like I was driving a bomb. I'll pass lmao 🤣
No more than driving a vehicle full of gallons of combustible fuel ;)
I have a 1985 Ford Mustang GT convertible that I’m thinking of converting to run on both Propane/Natural Gas since gas prices are through the roof
There really isn’t an upfit kit option out there, or at least upfits that exist are done to new vehicles coming off the line.
@@MattStephensRich im sure it can be done somehow. Ill have to do further planning
Bout to buy a crown Vic police interceptor but it only takes CNG and I had no clue that was even a thing until about a day ago😂
Hah good flag!
Idk why this is so scary to me....I keep thinking something will explode like that dodge did in California!
Not really; a little of a pop when you disconnect for releasing pressure, but nothing scary!
I half to ask, with the tank fully compressed. At 3000+ PSi. What's the range/distance of the vehicle? I'm assuming it's insanely extended.
Range is actually comparable to a full tank of gas.
@@MattStephensRich
2015 Chevrolet Trax Traditional
14.0 gallons of gasoline
2015 Chevrolet Trax GBT Technologies
8.58 GGE
That's only 61.3% of the effective range. So it's only 2/3 comparable to a full tank of gas.
I would like to see the motors in the tractor trailer.
The compressors? You can find a lot of great videos of those on TH-cam. Ultimately was off-limits while I was shooting. :)
Pls I med help fule tank has gas kit replacement
serious question, what if you run out of gas? can you carry around a gas can or something?
not really - since methane is a gas, you'd have to tow.
Good
Why they’re not popular like gasoline?
Most a lack of infrastructure and virtually no vehicle options.
What about hot days, this option is not safe at all
I mean, are you insinuating CNG can’t be used in warm weather?
@@MattStephensRich
I’m not insulting but all drivers are not the same. Some drivers follow the law country and they are always in speed limit but there’s some crazy drivers who swift or spinning while the engine hot and the windows are closed. That’s the time the car will explosion. And it’s not safe.
Is that make sense?
Honestly not at all lol or at least, if you’re asking “is CNG safe”, gratefully the answer is yes. Otherwise it wouldn’t be made available as a motor fuel.
Not trying to come across mean, but you ultimately used a run on sentence, and just restated “not safe”, and said the engine running hot and windows closed means the car explodes? Gratefully isn’t the case - again, otherwise would definitely not be available as a motor fuel.
@@harun9739 You're talking about the flashpoint of the fuel - the temperature at which it spontaneously combusts? Or are you concerned about the tank holding in higher pressures on hot days?
For human-bearable temps, this should be a non-issue.
It takes up a lot of Trunk Space
Yup
Any danger getting rear ended with the high pressure tank?
Ultimately this is why they have designed the tank to sit more inward within the back cargo area, giving more crumple space/ability to absorb the blow in a crash. Tanks are also crash rated to a certain extent.
@@MattStephensRich thanks for that explanation sir.
you bet!
I bought the car first time natural gas but some people told me is it dangerous in accident and car can explode
Gratefully not the case. Or at least, compared to a regular car that carries around gallons of combustible fluid that has a larger ignition range than methane.
Do you have a CNG car like that I'm interested?
Nope - this was a work car I had at time of filming. :)
So what is this? Unlimited fuel??
Do you think it is?
Wow that is a big trade-off considering there’s basically no trunk space in a car with a massive amount of trunk space. Also GGE is the dumbest unit. You should be billed by how many grams of a substance you are buying.
😊
It takes away from the performance of the vehicle. BTW, the car knows what type of fuel you are using because you need to change the components of the car to run natural gas, that was a stupid comment in the video.
I didn't say anything about the component integrations of CNG vs. gasoline fuel system? But yes, CNG runs at a different octane, alongside being a gas - which means injectors, fuel lines, and engine computers need to be updated for running the different fuel.
natural gas will be banned thou
Horrible video!
Appreciate any feedback on what was missed!
What is the compression station running on?🤣 I feel like its still gasoline... Is it efficient or like a zero sum game?
Compressors run on electricity!
