Abstract

Low pressure fuel, which may be mixed with air, is supplied to the engine via a desmodromic value j and high pressure fuel, which is heated by waste heat from the engine, is supplied via a desmodromic value k. Two thirds of the fuel is supplied at the low pressure during the compression stroke and one third of the fuel at high pressure at the end of the compression stroke to cause ignition.

Description

SPECIFICATION Two-stroke cycle engine Reasons, which will improve efficiency of the engine: 1) A power stroke, which will be realised on a revolution of the crankshaft.

2) The fuel come to cylinder in two parts, as 3) The low-pressure fuel and as 4) The high-pressure fuel.

5) The fuels come to cylinder through of injector, fuel feeding apparatus, compressor, etc.

6) The combustion product move off from cylinder through exhauster.

7) The increase of pressure by the fuel and air can happen with the waste warm of engine.

Can be advantageous the implementation of the above mentioned purposes by the conversion of existing engines and by design and production of new engines.

Background of the Invention In the relation of this invention in the lately 100 years are as 2-4 stroke cycle internal combustion engines the DIESEL- and OTTOpiston-engines. They have characteristics: bad efficiency, large fuel-consumption, imperfect combustion of fuel and the combustion products are poisonous for the environment.

I am ambitious correct above trabels, with my invention.

Summary of the Invention The present invention realize an improved efficiency engine, to which become on two way if we consider its method of application fields.

1. With modification of the all existing pistonengines.

2. With design- and production of the new piston-engines.

According the fuel using may be: 1) Two-stroke cycle engine, with using gas oils.

2) Two-stroke cycle engine, with using gasolines.

3) Two-stroke cycle engine, with using gases.

The above fuels and their mixture with air can come into the cylinder in which that burn and make a power stroke.

Any using fuels we divide two parts, that at charging of low-pressure fuel be 2/3 part of explosive fuel mixture. The 2/3 part fuel and the needed air will not be explosive mixture. This mixture will be compressed, which is not an explosive mixture.

The 1/3 part fuel get into cylinder, which with the mentioned 2/3 part fuel will be an explosive mixture. That with controlled explosion turn on the gas. After explosion the combustion product make a power stroke. Later the exhauster remove the combustion product from the cylinder. The increase of pressure by the fuel and air can happen, with the waste warm of engine.

Brief Description of the Drawing In the drawing FIG. 1 is a possible two-stroke cycle engine for any fuels. FIG. 2 is a low- and a high-pressure fuel feeding apparatus for L.P.

gases.

Description of the Preferred Engine This construction contain a cylinder (a), its have exhaust ports (b), piston (c), water jacket (d), crank case (e), connecting-rod (f), crankshaft (g), mixing chamber (h), injector (i), intake valve (j), for lowpressure fuel, intake valve for high-pressure fuel (k), for two valves desmodromic method (m), (n), throttle valve (o), pipe (p), cylinder head (I).

The increase of pressure by the fuel and air can happen, with the waste warm of engine, by the following equipments: fuel tank (t), suction pipe (s), throttle valve (u), compressor (v), highpressure fuel tank (t'), throttle valve (z), pipe (x), will going to the pipe of cylinder head (p), the (t') is in the water tank (k'), its water will be heated by the waste warm of engine through a heater (h"').

The (k'), is in a boiler (b'), in which is a preheater (he), this heater work at starting of engine.

1) Two-stroke cycle engine, with using gas oils.

2) Two-stroke cycle engine, with using gasolines.

3) Two-stroke cycle engine, with using gases.

Above constructions will be suitable for modification of the all existing 2-4 stroke cycle internal combustion piston-engines or design- and produce two stroke cycle engines.

Two-stroke/Revol ution 1. COMPRESSION STROKE.

2. POWER STROKE.

Any using fuels we divide two parts, that at charging of low-pressure fuel be 2/3 part of fuel by explosive mixture. The 2/3 part fuel and the air will not be explosive mixture.

The 1/3 fuel part will be compressed, which is not an explosive mixture.

The low-pressure fuel and air mixture come into the cylinder in a split second in time of compression stroke.

The high-pressure fuel come into the cylinder in a split second in end of compression stroke. This fuel turn on the mixture, which explode and the combustion product make a power stroke. When the piston will be in the under dead point the exhauster remove the combustion product from the cylinder.

The fuel 2/3 part and air can get into cylinder through of fuel injector, carburetor, fuel feeding apparatus, fuel-air mixing apparatus, compressor, controlled valve, etc.

The 1/3 fuel part can get into cylinder through of fuel injector, fuel feeding apparatus, compressor, heater, preheater, controlled valve, etc.

The low-pressure fuel tank, throttle valve, compressor, injector, controlled valves, etc.

construct the low-pressule fuel supply.

The compressor, high-pressure fuel tank, throttle valve, heater, water tank, boiler, preheater, manual operated throttle valve, automatically vibration valve, controlled valve lifting system, etc.

construct the high-pressure fuel supply. The increase of pressure by the fuel and air can happen, with the waste warm of engine.
