JPS619332A - Automobile provided with several lightweight gas bombs - Google Patents

Abstract

PURPOSE:To prevent the air-drag of a vehicle from increasing, by using bombs made of flexible materials and by also using elastic fastening belts for attachment of the bombs so that the bombs takes an flat plate-like shape to eliminate projections on the roof of the vehicle when the pressure in the bomb lowers. CONSTITUTION:Small diameter bombs 2 made of a thin membrane such as, for example, rubber, plastic, etc. which is reinforced with high strength fibers, are installed on an automobile 1. Further, the bomb 2 is attached to the automobile with the use of fastening belts 3, 4, 5 made of elastic materials so that when gas is completely consumed, the small diameter bombs are flattened. With this arrangement projections on the roof of the automobile are eliminated so that the air drag is not increased even upon high speed running with the use of gasoline.

Description

DETAILED DESCRIPTION OF THE INVENTION In recent years, as the dependence on oil as a liquid fuel has increased, conversion to various other types of fuel is being actively promoted as a safeguard against this situation. One of these is the use of LNG. This is liquefied methane gas, has a high calorie content, and is produced in the waste material process through methane fermentation of waste, making it compatible with the natural recycling process. Also, during the manufacturing process, sulfur is completely removed through hydrogen sulfide, making it a pollution-free fuel. It is also possible to limit nitrogen oxides to a relatively small amount, and from this point of view, pollution control 11-. It can be said that it is a suitable fuel for

However, the problem is that the volume is larger than that of liquid or solid fuels. In order to eliminate this drawback, L N
G is liquefied at a low temperature of 1/2 O0C, and various types of such low-temperature containers have been developed, but in any case, they are complicated and require advanced technology. Furthermore, the smaller the device is for use in automobiles, the more heat enters the device, making it difficult to maintain a low temperature. One way to avoid such low-temperature problems is to increase the pressure while remaining in a gaseous state and reduce the volume. In this case, the pressure is usually over 100 atmospheres and the gas is filled into pressure-resistant steel cylinders. In this case, the weight of the cylinder is extremely large, so it is not a problem when used in a mobile self-excited vehicle, although it is used in a fixed facility.

The present invention aims to provide a lightweight cylinder that solves the above problems, and utilizes recently developed high-strength fiber reinforcement technology. In other words, thin rubber and plastic films reinforced with glass, steel fibers, plastic nylon, Kepler fibers, etc.
They make cylinders.

These cylinders are not large-diameter cylinders either, but rather a combination of many small-diameter cylinders. This allows it to be thin and lightweight, and to be adapted to a given space within the necessary limits for automotive applications. Also, in the unlikely event of a car accident, there is a low probability that all the cylinders will be damaged, and the damage will be limited.

A gas engine that uses such methane gas may be basically the same as a current gasoline tank. Conventional town gas that contains 1 element of water requires countermeasures against problems such as knocking due to early ignition, but LNG consisting only of methane gas has no problems at all. Therefore, only a portion of the carburetor needs to be modified. Therefore, it is easy to create a multi-fuel engine that can be switched and used with either gasoline, 2M fuel, or NG fuel. Therefore, it is possible to run on LNG in the suburbs of cities where LNG piping is available, and to use gasoline in remote areas where there is no LNG piping.

In this case, a cylinder installed on the roof of a car is not uncommon as it also creates air resistance. However, it is difficult to remove
It is a hassle when using it again. Therefore, in the present invention,
The tightening belt for attaching the cylinder is made of elastic material such as spring or rubber. By doing this,
As the gas in the cylinder is used and the pressure decreases and approaches atmospheric pressure, the force of the tightening belt dents the cylinder, which is made of a flexible material such as rubber, into a flat plate.

This eliminates any protrusions on the roof, so there is no increase in air resistance even when running on gasoline at high speeds. It is also suitable for using all the gas in the cylinder, as the gas is pushed out to the end by the tightening belt.

Next, explanation will be given with reference to the drawings. FIG. 1 shows the overall structure of the present invention, and numeral 1 indicates an automobile in which the present invention is installed. However, it shows a bread type with a long roof. This is primarily because there is thought to be a lot of demand for commercial vehicles.

2 is a small-diameter cylinder made of a thin film of rubber or plastic reinforced with high-strength fibers. 3.4.5 is a tightening belt,
It is made of a stretchable material such as a steel spring or rubber, and when the gas has been consumed, the small diameter cylinder 2 is flattened. Reference numeral 6 denotes a connecting pipe, which is made of a flexible rubber pipe or the like in order to cope with movement due to the flattening of the small diameter cylinder 2. This connecting pipe 6 is led to a carburetor. Moreover, it is a matter of course that a pressure reducing valve is provided in the middle.

As an example, if you calculate the space required to install it on the roof of a normal bread-shaped passenger car, you can get a width of 1cm, a length of 3cm, and a height of 9cm. Assuming that the space utilization rate is 70%, /,! ×3×0.3×0.7=/,! ;7! ;
It is rn. Assuming that the filling pressure is 10 atm, this is approximately equal to the calorie of 1 gasoline, so it is approximately /j in terms of gasoline.

If the filling pressure can be increased to 20 to 30 atmospheres due to the performance of recent reinforcing fibers, it will be possible to increase the capacity to a level comparable to that of current gasoline tanks.

However, in general, if gas operation is limited to areas near cities, it is easy to carry gas, and IO atmospheric pressure is sufficient. In addition, one-box vehicles, which have been frequently used in recent years, have a long roof, which is advantageous, and the same is true for buses. It is also possible to install it at the rear of buses etc. Furthermore, in the case of a bus that travels on a fixed route, it is easy and suitable to fill in planned short intervals. In addition to this, switching to a gas engine is also advantageous in terms of pollution control.
