1 oil to gas
Introduction :
ldquo; oil to gas rdquo; actually installed to the vehicle by means of a gas used to make it may burn freely switch between gasoline and burning natural gas. Case where the water temperature is generally above 60 ℃, the apparatus can be automatically switched from burning natural gas fuel to burn. If natural gas fast burn, and you can also force the state to switch back to burning gasoline, making hybrid vehicles.
Advantages:
high economic efficiency. Easy and uniform mixing of air and gas, more complete combustion in the engine, clean, not prone to carbon deposition, good antiknock performance without dilution of the lubricating oil, so that the parts wear greatly reduce the engine cylinder, and can extend the life of the engine life of the grease.
social good. Compared to petroleum fuel, the gaseous fuel energy loss during the manufacturing process is small, less harmful emissions of pollutants, it is more advantageous for environmental protection.
safe. Slight gas leak itself, quickly diffuses into the atmosphere, the various components of the fuel gas system, in particular the sealing portion, are subject to stringent inspection. Therefore, natural gas as a motor fuel is relatively safe.
Gas and air are easily mixed uniformly in an engine, more complete combustion, clean, good antiknock performance, making the parts inside the engine cylinder greatly reduce wear, extend the life of the engine and the life of the grease. On the other hand the gaseous fuel energy loss during the manufacturing process is small, less harmful emissions of pollutants, and more beneficial to the environment. For the majority of car owners, ldquo; oil to gas rdquo; the biggest benefit is that we can save money. Business in Hefei gas price is 3.2 yuan / cubic meter, 93 gasoline prices about 7.4 yuan / liter. Equivalent per 1.1 m3 of natural gas in accordance with the energy ratio of 1 liter of gasoline is calculated, using natural gas as fuel than gasoline to save more than half the cost.According to a survey of taxi drivers in Hefei, the use of natural gas costs about 0.25 yuan per kilometer. In any case, ldquo; oil to gas rdquo; for those vehicles that use more frequently, the cost savings that are very impressive.
Disadvantages:
Due to the low energy density of the gaseous fuel, the amount of natural gas vehicles carrying less fuel, and gasoline mileage relatively short. Most of the currently used natural gas engine is converted from a gasoline engine, gasoline vehicles and thus power after switching to the natural gas tend to fall about 10 percentage to 20 percentage.
due to the current natural gas vehicle is modified on the basis of the original gasoline and diesel vehicles, based on the original gasoline and diesel fuel systems are mostly reserved. Therefore, to increase the natural gas fuel system in the original car, especially the efficient use of gas cylinder original car trunk space is reduced, the weight itself is also increased.
Natural gas is a gaseous fuel, is not easy to store and carry. To this end, a pressurized or liquefied for bottling, also need to build than gasoline and diesel filling stations gas station investment is large, the relative lack of filling stations in the area, plus gas is more difficult.
The application of car:
In general, the price of more than 20 million high-class cars as well as some off-road vehicles, no need to gas, because of this type of car fuel injection quantity, fuel injection time control is very accurate, it will be adjusted according to the situation in the oil, gas and once changed, but also may affect the normal operation of the intelligent control system of the engine.
Further, the low frequency of car owners have no need to gas. As a private car commuting purposes, the annual mileage is generally in twenty thousand kilometers, but the cost of oil to gas in 5000-78 to pay four thousand dollars, so run a long time to recover this part of the conversion costs. This low frequency of car owners, and not worthwhile.
annual mileage of more than 30,000 km of car, more suitable to gas, but if the car has been seven or eight years of age, you should conduct a comprehensive inspection of the condition prior to gas and make the necessary repairs, otherwise these cars because of their aging components result in performance degradation.
doubts:
After the oil to gas, if a collision wouldExplosion it?
Some owners are most worried about the oil to gas the car will explode after the collision. In fact, in our country at present ldquo; oil to gas rdquo; this technology is mature, experts explain, have been high pressure gas cylinders, fire, shootings and other tests, the possibility of an explosion due to impact is very small, but only if the consumer who must be tuning into the formal conversion.
After the oil to gas, then oil consumption big?
To meet a combustion system using two fuels, both of which are inherently impossible to make the best state. After the change the basic car to use natural gas, so their engines are biased towards the use of natural gas for debugging features. Then gasoline, fuel consumption may be higher than before about 10 percentage.
After the oil to gas, maintenance, pay attention to what?
open oil to gas the car driver must conduct specialized training, usually we have two weeks to check again for leaks. Check method is very simple, empty beverage bottles filled with water and a few drops of detergent added, after shaking, applied to the vehicle valves, switches, pipe joints, etc., to see whether the bubbles emerge, once the bubbles take out, it means there is a leak of natural gas vehicle, it should be repaired. Also, note that the cylinder life is generally 15 years, for security reasons, the provisions of the relevant departments, car oil to gas cylinders once every two years for inspection, once the cylinders have worn or damaged after the new bottle must be replaced before you can continue to use. Accordingly, the vehicle gas changed, typically by two cylinders with a fixed gate, a layer between the cylinder and the gate pad strip, the protective role of cylinders. Once the pads are damaged, the cylinder will be subject to wear and tear. Therefore, owners should ldquo; keep an eye rdquo; pads, once the damage occurs should be replaced to prevent gas cylinders being destroyed.
ldquo; oil to gas rdquo; safe?
CNG cylinders the internal operating pressure is about 200 kg. Many owners are worried, carrying a large bottle everywhere, once rear-end accident, the cylinders will not be a big bomb? In fact, this is not necessary to worry about the current ldquo; oil to gas rdquo; technology is very mature, high-pressure cylinders have been, extreme fire testing, installation of gas apparatus also has a self-closing system, severe collision such as when an accident will automatically deflated, becauseThe possibility is very small crash explosion.
After the accident, the insurance company claims it will?
Some car owners worry that the terms of the insurance contract after the accident, car modification, the insurance company is not compensable. In this regard, the insurance industry sources said, although ldquo; oil to gas rdquo; vehicles belonging to the list of modified cars, but the insurance company claims in dangerous condition, leading to even more concerned about whether or not the direct cause of the accident caused due to vehicle modification, If this is not the behavior modification caused an accident, you can get a payment. But if the owners decide ldquo; oil to gas rdquo;, and have their own car and commercial insurance policy, it is best first to inform the insurance company will retrofit program within the insurance period, the insurance company so that we can re-evaluate the risks Once or permit renewal fee plus renewal, vehicle accident claims and the line will be the general program, modification of payment is no longer an obstacle.
