(54) METHOD OF OPERATION OF A FOUR-TURNING INTERNAL COMBUSTION ENGINE

The image relates to mechanical engineering, in particular to twin-engine construction, in particular to methods of operation of four-stroke internal combustion engines.

Methods are known for the operation of four-stroke internal combustion engines for supplying fresh charges to lilinsra with an additive of exhaust gases and ejected gas, for example, boi, burning the mixture formed in the cylinder and converting the energy of the expanded gases into the rotational energy of the shaft C I

When implementing such methods, the supply of water and exhaust gases to the cylinders of the engines contributes more efficiently to the use of heat when burning fuel.

In the known methods, however, no measures are taken to reduce losses during the ejection of water by spent gas, as well as losses associated with overflow of spent gas. As a result, all opportunities to improve engine economy are underutilized.

The purpose of the invention is to increase efficiency and reduce toxicity.

This goal is achieved in that the additive of the ejected liquid into the cylinders is carried out at the end of the intake stroke using alternate exhaust gas bypass from one cylinder to another in pairwise connected cylinders, the phases of which are shifted to BDO.

The drawing shows a diagram of the engine, working on the proposed method.

The engine contains at least four cylinders 1–4, in each of which nozzles 5–8 are installed, cooftue with a fuel pump 9. Channels U and 11 communicate cylinders 2 and 3, 1 and 4, respectively, and serve for exhaust gas bypass. Between cylinders 1 and 4 & channel 11 is set dosing mouth 9545834

Both dosiruydik device-fires in the small part of its supply are communicated with the capacity 14 through the re-vii in the design of the game. This dose of the control valve 15 is sent to him. and firing the ignition.When the main escort is being injected 16. The control valve is from the end of the fuel through the nozzle period

by means of a hydraulic communication 17, the latency is reduced and the fuel is burned

with a rail (not specified) of the fuel pump 9.- the process of feeding it into the cylinder, is ensured by the following dimming of an economical, or low toxicity cycle.

When the engine is running, liquid, for example, low toxicity is due to

measures water comes from the tank through a pipe that the growth rate and maximum

Claims (1)

Claim Cylinders are recharged. In the case when the engine does not work, the liquid level in the tank is lower than the cross sections of the metering devices and the water is not. enters the cavity of the channels 10 and 11. The total coefficient of excess air for the engine with this method of supplying liquid, for example water, to the cylinders increases, the vapor-gas mixture under pressure delaminates the fresh charge, which contributes not only to lowering the temperature of the cycle, but also to initiating fuel combustion. As a result of the fact that the water supply control valve 15 is connected by hydraulic connection 17 to the rail of the fuel pump 9, with an increase in the fuel supply, the amount of sawn water increases with the exhaust gases. In engines with ignition from The method of operation of a four-stroke internal combustion engine by supplying a fresh charge to the cylinders and adding bypassed exhaust gases with a liquid ejected by them, for example water, burning the mixture formed in the cylinder and converting the energy of the expanding gases into rotational energy of the shaft, characterized in that, in order to increase economy and To reduce toxicity, the ejected liquid is added to the cylinders at the end of the intake stroke by alternating bypass of exhaust gases from one cylinder to nother in paired cylinders fazykotoryh shifted by 360 °.
