JPS5990733A - Changing-over of vehicular fuel - Google Patents

Abstract

PURPOSE:To improve the economical property by a method wherein fuel tanks for driving and for operating auxiliary functions such as pump, crane and the like are respectively and separately equipped and either one of fuels, which are different from each other in the field of application, is supplied to a single engine mounted on a vehicle in response to the current use application. CONSTITUTION:A fuel tank for driving 7 and a fuel tank for operating auxiliary functions 8 are provided and fuels with different prices (or of different kinds) are stored in the respective tanks 7 and 8 in a vehicle, which transmits the power developed by the actuation of a main engine 1 through a power transmission change-over device 2 to the rear wheels 3 of the vehicle or to an operating device of annexed functions 4. When the power transmission change-over device 2 is changed-over to the rear wheel 3 side of the vehicle, both a fuel feed solenoid valve 5 and a fuel return solenoid valve 6 are open so as to communicate the tank 7 to the main engine 1 in order to supply the fuel in the tank 7 to the main engine 1. On the other hand, during the operation of the annexed functions, similarly the comparatively low price fuel in the tank 8 is controlled to be supplied to the main engine 1.

Description

[Detailed Description of the Invention] In recent years, with the development of the automobile industry, labor-saving automation, social needs, and the increase in the horsepower of diesel engine tanks to 11 horsepower, tank E-Li-1 " I (pump for discharging pickled people, various scales of automobile equipment (; iii cranes or forklifts, etc.) After that, each shore f!::, for example, a pump, a crane or a boat.
'↓ Wholesalers etc. were operated, beach work, -1
- Contributing to the rationalization and enlargement of elementary schools (・Z)c In this case, the main engine on the tower is mainly the dog horse evil engine, and it is also used for driving.
1 Functional engine 11 The same fuel can be supplied to the main engine while the main engine continues to operate, and the power transmission device can be switched to run, or the main engine can be run for dual purposes, such as by stopping running and operating a pump, for example. It has a mechanism that utilizes rotational energy.

However, some of the attached functions, such as pumps that are sufficient to achieve the purpose of operation with a fraction of the horsepower possessed by the main engine, or even higher output due to insufficient power in the driving area. In cases where crane work or forklift horsepower is required, the output of the main engine decreases by 1 month in the former case, or the output of the main engine decreases in the latter case. By supplying increasing amounts of fuel, it is possible to meet the demand for required output that differs from the driving condition, and also to reduce the price difference.In order to meet such demands, this invention also incorporates functions other than driving. This relates to a method in which a vehicle is equipped with separate fuel tanks for running and for operating 01 installation functions, and 41q of fuel t1 is supplied to the main engine 1t1 in accordance with the purpose of the main engine. .

The drawing is a system diagram Q explaining an appropriate application example of this invention.
Gl. Reference numeral 1 is a main tower gate, and 1 can be selectively switched to the vehicle rear wheel 3 or the attached function driving device 4 via a power transmission switching +i-device 2.

Depending on the selection switching of the power transmission switching device 2 to 3 or 4, the fuel supply solenoid valve 5 and the fuel return solenoid valve 6
is activated, and when the main power source/semon power is connected to the traveling vehicle @ 3 by the power transmission switching device 2 and the vehicle is in a traveling state, both the fuel supply solenoid valve 5 and the fuel return solenoid valve 6 are connected to the traveling fuel. If there is a moat opened to communicate between the tank 7 and the main engine 1 or the main engine 1, and a moat is set to close the flow path between the tank 7 and the fuel tank 8 for operating the attached function, the main engine will have a running system. ,(
(The vehicle is supplied with fuel and operated. This vehicle stops running and the vehicle is equipped with an installed function 4 such as a pump, a crane or a lift 1-
When using the main engine as a power source, 'r: F, ,,
If the gear of the power transmission switching mounting 2 is switched, the main engine 1 becomes 1i.
When power transmission is switched to the auxiliary function 4, the fuel supply solenoid valve 5 and the fuel return solenoid valve 6 are also automatically switched, and the fuel for the main engine is supplied to the auxiliary function operation fuel tank 8.
The excess amount is supplied from the return solenoid valve 6 (
The fuel is returned to the fuel tank 8 and switched to a fuel different from that used during driving, such as output 1 price corresponding to the operation of the attached function, so that the operation of the main engine can continue smoothly and correspond to the operation of the attached function. Also, according to this invention, by distinguishing the use of driving fuel and fuel for operating other vehicle functions, diesel oil collection tax will be imposed on all fuels used for driving diesel vehicles on general roads. However, the use of diesel fuel, which meets the standards of the Diesel Tax Act, is taxed for vehicle functions other than road driving, such as pumping on tank trucks, lifting on forklift trucks, and lifting and turning cranes on crane trucks. Even if the power of the main engine is not used for fuel and (-) operation, the main engine operation difference for operating the vehicle's main engine function is compliant with the light oil standard under the tax law. If you prepare fuel other than diesel oil in tank 8 (JIB')::':, :I"), it is possible to use diesel oil in tank 8 when driving. It is reasonable to use other oil types during work other than when driving, without having to pay a tax on road transport.

In this explanation, 1d℃・fuel tank for operating the attached function 8
As explained above, one unit is installed, but if it is necessary to select and switch between two or more types of fuel depending on the type of annexed function being operated, the required circumference, etc., the number of cylinders may be increased as necessary. be able to.

For this, 114, 1, and 17 J are installed in the 4 pins that can be selectively opened and closed at the same time, according to the above explanation. In addition, the attached p, I4 capacity 1j Busy-C is the above-mentioned construction machine (distribution, 111j::1111) 1 port machinery, civil engineering equipment I (land-building machinery or heavy duty) Use 1'1 Ritsufu・Tunriu (including those listed in 4).

In addition, when driving within a factory area or on private land, etc., when driving in a manner that does not fall within the scope of 11 ``Lambda of the Oil Tax Law'', a separate 1 liro [j fuel refilling device must be installed. The present invention can also be applied to driving using fuel other than the light oil standard according to the light oil tax law.
