Abstract

Technical solution is concerning to starting and acceleration actuators for big performance range devices, particularly vehicles and working mechanisms. The energy stored in the compressed air tank, the hydrogen generator and electric accumulator allows two or three times output increase of the combustion engine in a short but sufficient time. It makes possible that small internal combustion engine for example, starting the aircraft, has sufficient power for working mechanisms and city vehicles motors by using accumulated pneumatic energy and reduced consumption of conventional fuels. For agricultural technology is use of air pressure energy from renewable sources.

Description

Technical field

The technical solution relates to starter and accelerator drives intended to drive high-power devices with short-term effect, especially during start-up, acceleration, lift, work, with different focus (aviation, special-purpose vehicles, working mechanisms, local energy sources).

BACKGROUND OF THE INVENTION

Drives using accumulated energy are currently widely used in industry, transport to drive vehicles, technological equipment. Their fundamental mission is to be independent of hydrocarbon fuels and to be safe in an environmentally demanding environment. The most common way of storing energy is in the form of electrical storage and storage in a compressed or liquefied gaseous medium. Persistent problems are in the weight of the storage means. Motors (electric, pneumatic, combustion) are designed for the need for long-term nominal performance.

Many applications with short and extreme power requirements are currently solved by oversizing engines that are unused for the rest of the time, increasing weight and investment parameters.

The essence of the technical solution

The solution according to the invention applies the use of an internal combustion engine without changes and major modifications, which has a high pressure intake connected to a compressed air reservoir filled with quasi isothermal compression in cascades with intercooling, and the compressed air inlet is from from a high pressure compressed air reservoir. By adjusting the throttle, the optimum dose of compressed air is generated which reaches the combustion volume at the top dead center of the piston. The batch expands by moving the plunger down and cooling. The expansion ratio regulates the instant power and efficiency of the engine as required.

The hydrogen generator allows the engine to be supplied by the addition of hydrogen with the possibility of determining the ratio of combustion of conventional fuel and accumulated sources in the electric accumulator and the compressed air reservoir.

A public utility source may charge an electric accumulator and a compressed air reservoir, as well as a wind or photovoltaic source, depending on current conditions, when the working means is intended to work on an available circuit near the charging sources, e.g. Tractor working in the field near the power supply. The technology will allow a significant reduction in diesel consumption. Similarly, urban, passenger, public and special-purpose transport.

With local power generation or operating mechanisms, an internal combustion engine coupled to an electric or hydraulic power generator is capable of delivering superior power in a hybrid power system.

The transport and working mechanisms have an internal combustion engine connected to a wheel axle or mechanisms of a working machine, servomotor, forklift, van, tractor, etc.

EXAMPLES

The main design is working mechanisms that work in a relatively small area with the possibility of recharging accumulated energy from renewable sources, whose converters are portable or purpose built in places of work or transport activities. In this way, starting and accelerating drives can be applied in urban vehicles, agricultural machines with the effect of saving oil, gas and reducing emissions. In addition, the vehicles will be equipped with compressor braking and electro-induction.

Another embodiment is purpose-built vertical or short-range aircraft engines that apply a full power compressed air reservoir to the time required for take-off, load lift and landing.

Modifying the engines consists only of changing the intake to air pressure metering and various combinations of fuel inlet, e.g. pressure injection of liquid fuel without changing the original design, pressure input of gaseous fuel by throttling into the dosing tank.

For engines with low weight requirements, the valve timing adjustment is designed so that the engine operates in only two of these, explosion and exhaust. After the explosion of the mixture and expansion, the intake valve (s) closes, followed by the exhaust through the open exhaust valve (s). After opening the intake valve and closing the exhausts, the air (mixture) pressure rises above the piston at the top dead center and the mixture ignites. Compression is eliminated due to the nature of the inlet pressure. In this embodiment, the pressurized air reservoir may use oxygen supplied and preheated from the liquid state.
