I welcome you to write to me John at strokerengine@hotmail.com with questions, I may have an answer.
StrokerEngine in association with supporting companies has been developing a line of Compressed Natural Gas Engines.
These engines are designed for "off road" use only.
The government is way behind in their thinking of alternative fuels for vehicles. They impossed difficult certification proceedures for EPA approved CNG systems and what limited systems are available are expensive because certification can cost upward of $200,000
We can not recommend using these engines on the highway, that would be illegal, we only point out that "if" you could, you would subtancially lower your fuel cost.
CNG sells for around $2.30 at a pump, and if you pumped from home about $1.50.
The governments needs to get onboard and allow wide spread CNG usage, and by the way it is safer than gasoline tank in an accident.
Most natural gas engines found on the highway are in large trucks, buses and some fleet cars.
The few small cars using CNG are opperating using conversion kits. The engines we are building are intend as complete replacement units that provide as much or more power on CNG than the original gasoline engines.
We are still in development of our full line of engines as we move into higher production.
Currently we are building engines to order based on...
Chevrolet
Small Block 350 383 450 cid
Big Block 454 502 590 700 cid
Ford
Small Block 302 347 351 408 427 450 cid
Big Block 460 545 600 cid
Our goal in to make powerful engines that are not currently available.

This video is Boone Pickens talking alternative energy.
His point is we need all options but Natural Gas is our best option for supplmenting gasoline and diesel

According to the International Association of Natural Gas Vehicles there are approx. 4 million NGVs in use worldwide, of which 1.6 million are in Argentina and 1.5 million in Pakistan.
Italy’s fleet of 430,000 NGV is by far the biggest in Europe, followed by Germany with 55,000 and Bulgaria with 25,000.

Natural gas is a fossil fuel consisting primarily of methane but including significant quantities of ethane, butane, and pentane - heavier hydrocarbons removed prior to use as a consumer fuel —as well as carbon dioxide, nitrogen, helium and hydrogen sulfide.

One GGE of natural gas is 127.77 cubic feet. This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values: 900 BTU/CF of natural gas and 115,000 BTU/gallon of gasoline).
One GGE of CNG pressurized at 2,400 psi is 0.77 cubic feet. This volume of CNG at 2,400 psi has the same energy content as one US gallon of gasoline (based on lower heating values: 148,144 BTU/CF of CNG and 115,000 BTU/gallon of gasoline. Using Boyle's Law, the equivalent GGE at 3,600 psi is 0.51 cubic feet which corresponds to 14.5 liters or 3.82 actual US gallons.
The National Conference of Weights & Measurements (NCWM) has developed a standard unit of measurement for compressed natural gas, defined in the NIST Handbook 44 Appendix D as follows: "1 Gasoline [US] gallon equivalent (GGE) means 2.567 kg (5.660 lb) of natural gas."
When consumers refuel their CNG vehicles in the USA, the CNG is usually measured and sold in GGE units. This is fairly helpful as a comparison to gallons of gasoline.

1 Multiply the speed in MPH by 5,280 feet per mile. The result is the speed in feet per hour. For example, 55 MPH is 290,400 feet per hour.
Step2
Divide the speed in feet per hour by 3,600 seconds per hour. The result is the speed in feet per second. For example, 290,400 feet per hour is 80.667 feet per second.
Step3
Alternatively, for a quick and dirty estimate, adding 50 percent is close enough (accurate to better than 2.5 percent).
Step4
To convert feet per second into MPH, multiply by 3,600 seconds/hour and divide by 5,280 feet/mile. For example, 50 feet per second equals 34.09 MPH. Alternatively, simply divide the speed in feet per second by 1.4667 (seconds*feet)/(hours*miles). For a quick estimate, take off one third and you'll arrive at an answer accurate to better than 2.5 percent.
