What you Should Know About Using Natural Gas Vehicles
Will I Receive the Same Fuel Mileage and Vehicle Performance?
Against standard evaluations, methane carries extra British Thermal Units (BTUs) than gas. The power content material of gas depends at the season and oxygenated gasoline components like methyl tertiary-butyl ether (MBTE) [used to increase the oxygen levels] that cut back emissions.
BTU ranges for gas
- 114,500 for a summer season gallon of gas w/ no components
- 112,500 for a wintry weather gallon of gas w/ no components
- 112,000 for summer season blends with MTBE
- 110,210 for summer season blends with ethanol
- 112,210 for wintry weather blends with ethanol
BTU ranges for herbal fuel
- 114,000 yr spherical
BTU ranges for diesel
- 129,500
The transparent winner and costliest is diesel with 129,500 BTUs. Because fueling stations do not need to put it on the market that they’re the use of a ten% ethanol combine of their gas, maximum do not; then again, maximum stations dispense this mixture.
What is the Difference Between Dedicated and Converted Vehicles?
Dedicated cars
- Runs on 100% herbal fuel
- Dependent on CNG fueling stations
- Can no longer flip off the gasoline whether it is overheating
- Expensive engine re-configurations to take care of 0 lubricants and top warmth ranges
- High upkeep prices
- Reduced torque and HP
- Reduced mileage
- High conversion prices
Converted cars
- Runs on gas or herbal fuel
- Runs on diesel + herbal fuel aggregate
- Doubles the riding vary
- Switch fuels whilst riding on the turn of a transfer
- Starts on gas or diesel to lubricate the engine then switches to herbal fuel
- Low upkeep prices
- Increased torque and HP
- Increased mileage
- Low conversion prices
What is the Difference Between Aspirated and Direct Injection CNG Kits?
- Aspirated: These techniques are first technology easy generation. Aspirated kits generally price much less since and are quite easy and simple to put in. They have a closed loop controller that receives comments from an oxygen sensor to stay the automobile running optimally. The efficiency of those techniques is restricted for the reason that air consumption should be throttled down for them to paintings correctly. Also, aspirated CNG kits have a tendency to cause the “Check Engine” mild which is a not unusual incidence. This software is meant for older cars with a carburetor.
- Direct Injection. These techniques are the leaders in CNG Conversion Kit generation. They make the most of an impressive microprocessor which helps the integrated computerized correction and calibration gadget. Because those techniques are designed the use of complicated electronics and ship some distance awesome efficiency they are going to price greater than aspirated kits. They have advanced considerably lately. The newest generation in those techniques makes use of intensive digital sensors, injectors, and a 32 bit laptop that integrates with the automobile’s laptop. This supplies the most productive gasoline economic system and function. A “Check Engine” mild isn’t appropriate with those installations.
Are There Special Maintenance Needs for CNG Converted Vehicles?
Natural fuel engines paintings necessarily the similar manner as gas engines. An air-fuel aggregate is injected into the consumption manifold, drawn into the combustion chamber, after which ignited by way of a spark plug. Most engine provider necessities are very equivalent and will also be treated by way of a broker, car store, or educated mechanic. If there’s a retrofit restore wanted, reminiscent of a erroneous injector or free compression fittings, those could be sorted by way of the installer.
Do Conversions Increase my Maintenance Costs?
Converted cars require decrease upkeep and HALF the standard oil and clear out adjustments. Using CNG maintains the oil viscosity, inflicting much less put on on more than a few engine portions such because the pistons, valves, and the pinnacle partitions. The gases are burned extra successfully emitting no destructive or filthy carbon deposits which assists in keeping your oil cleaner. Using CNG additionally extends the lifetime of the engine in large part because of the containment of the oil movie that collects at the cylinder partitions. This containment prevents oil from transporting to different engine portions not like engines working on gas or diesel.
Conversion Kits
- Gasoline CNG Conversion Kits run on both 100% gas or 100% herbal fuel (Bi-Fuel CNG Conversions). A CNG tank is added to carry the herbal fuel. The addition of any other gasoline tank doubles the riding vary. Bi-fuel conversions a great deal cut back your gasoline and upkeep prices. Because the gasoline combusts totally, your engine remains a lot cleaner. These conversions additionally cut back oil and clear out adjustments. The cleaner burning gasoline extends the lifetime of your vehicles and vehicles.
- Diesel CNG Conversion Kits mix a mixture of each diesel and herbal fuel, Dual-Fuel. This a great deal reduces the intake of high-priced diesel gasoline. Expect an will increase your mileage, and a discount in upkeep of high-priced oil and clear out adjustments. The air/herbal fuel aggregate is denser. This denser upper octane aggregate creates extra energy and higher torque. The cleaner burning gasoline extends the lifetime of your vehicles and buses.
Benefits to the Vehicle
Trucks & Cars Running on CNG
- Natural fuel carries upper BTU ranges than gas (125 vs. 90) because of ethanol and oxygenated gasoline components within the gas.
- Reduces the Fuel & Maintenance Costs Approximately 40%.
- Combusts with out self-ignition and protects your engine from knocking, even on engines with upper compression and potency ranges.
- Combusts 100% because of a correct air to herbal fuel aggregate at ambient temperatures.
- The oil that lubricates the engine is much less infected and decreases oil and clear out adjustments in part.
- There aren’t any sediments and the spark plugs are stored blank. Oil at the partitions of the engine cylinders aren’t washed off.
- Combustion gases aren’t corrosive. By no longer destructive metals, the lifetime of the exhaust pipe and silencers is longer.
- The gaseous nature of the gasoline gets rid of the scanning movements within the cylinders right through speedy acceleration classes, with the good thing about lowering the corrosion of steel surfaces.
- The engine gifts nice efficiency flexibility right through accelerations with out irregularities or backfires, even at low direct pace.
- Converted cars might transfer from the use of CNG to gas by way of merely pushing a button whilst riding.
- CNG gas bi-fuel gadget doubles the auto’s riding vary.
- CNG conversions run smoother and extra quietly.
- Vehicles perform in all terrains, even throughout mountains. For instance, a truck with a 37-ton load drove above 4,800 meters top within the Peruvian Andes in May 2008.
- CNG works advantageous beneath any local weather situation. Since the gasoline does no longer freeze no longer even at low temperatures the automobile will all the time be in a position for use.
- System is totally reversible and will also be transferred to different cars after inspection
Three Main Components to a Vehicle Conversion
- CNG Conversion Kits
- CNG Tanks
- NFPA-52 Certified top force portions
The CNG tank will also be fixed in numerous puts. Most standard places are within the trunk or within the mattress of the truck. A top force gasoline line routes the methane via a clear out then to the engine division. The newly put in 2-stage regulator will cut back the top force right down to ambient ranges nearer to 36 PSI. The added noise relief injectors will then dispense the fuel. This procedure is managed by way of the gadget’s ECU which is programmed to dispense the herbal fuel to compare automobile’s or truck’s authentic gasoline mapping. Sensors and computer systems regulate the fuel-air aggregate for top efficiency. CNG conversion kits don’t cut back your automobile or truck’s efficiency.
Fueling at CNG stations is rather like you have been fueling with gas or diesel and takes an identical quantity of time. The two tanks will double your riding vary. You nonetheless want to use gas as that is required to begin, lubricate, and heat the automobile. CNG conversion kits are programmed to offer protection to towards over the top warmth, and surprising adjustments in riding prerequisites. Should you wish to have to damage closely, unexpectedly accelerate, or hit a steep hill your gasoline gadget will mechanically transfer again to gas for the wanted further energy.
Converted cars paintings similar to the unique. Adding the brand new gasoline gadget is totally non-invasive and simple to opposite. Sequential port injection techniques from depended on producers don’t regulate or intrude with any of the unique engine producer (OEM) manufacturing facility settings or gasoline gadget nor do they tamper with any engine units or controls. Because there’s no tampering, there’s no violation with anti-tampering rules.
