Description

Oblasť technikyThe field of technology

Technické riešenie sa týka šesťtaktného spaľovacieho motora so vstrekovaním vody do valca a spôsob jeho činnosti.The technical solution concerns a six-stroke internal combustion engine with water injection into the cylinder and the way it works.

Doterajší stav technikyCurrent state of the art

V súčasnosti je najznámejším a najvyužívanejším motorom štvortaktný motor. Štvortaktný motor, taktiež označovaný aj ako štvordobý motor či ľudovo štvortakt, je piestový spaľovací motor pracujúci na štyri doby alebo inak povedané v štyroch taktoch. To znamená, že pracovný cyklus motora prebehne počas štyroch zdvihov piesta a dvoch otáčok kľukového hriadeľa. Podľa spôsobu zapálenia zmesi sa pracovné cykly mierne odlišujú pre zážihový a vznetový motor.Currently, the most famous and most used engine is the four-stroke engine. A four-stroke engine, also referred to as a four-stroke engine or colloquially four-stroke, is a piston combustion engine operating in four strokes or in other words in four strokes. This means that the working cycle of the engine will take place during four strokes of the piston and two revolutions of the crankshaft. Depending on the way the mixture is ignited, the working cycles are slightly different for spark-ignition and diesel engines.

Zážihový štvortaktný motor má nasledujúce pracovné cykly:A gasoline four-stroke engine has the following duty cycles:

1. Nasávanie - Pri pohybe piesta smerom nadol sa priestor nad piestom zväčšuje a zároveň sa otvoria aj nasávacie ventily. To spôsobí pokles tlaku nad piestom (tlak nad piestom je nižší ako atmosférický tlak). Tento rozdiel tlakov umožní motoru nasať do valcov cez nasávacie potrubie potrebné množstvo vzduchu aj s palivom. Vzduch a palivo spolu tvoria zápalnú zmes.1. Intake - As the piston moves downward, the space above the piston increases and the intake valves open at the same time. This causes a drop in pressure above the piston (the pressure above the piston is lower than atmospheric pressure). This pressure difference will allow the engine to suck in the required amount of air and fuel into the cylinders through the intake pipe. Air and fuel together form an ignitable mixture.

2. Kompresia - Potom, ako piest dosiahne svoj dolný úvrat, sa začne pohybovať smerom hore. Piest svojím pohybom smerom hore stláča zmes, ktorá sa vďaka tomu zahrieva a pretože sa nemôže rozpínať, stúpa aj tlak. Vysoká teplota a tlak podporuje odparovanie paliva a jeho premiešanie so vzduchom a zmes je výbušnejšia. Počas kompresie sú nasávacie a výfukové ventily zatvorené.2. Compression - After the piston reaches its bottom dead center, it begins to move upwards. With its upward movement, the piston compresses the mixture, which heats up as a result, and because it cannot expand, the pressure also rises. The high temperature and pressure favors the vaporization of the fuel and its mixing with air, and the mixture is more explosive. During compression, the intake and exhaust valves are closed.

3. Expanzia - Počas tejto fázy na zapaľovacej sviečke preskočí iskra, ktorá zapáli stlačenú zmes. Po zapálení začne zmes expandovať a piest posúva smerom dole k jeho dolnému úvratu.3. Expansion - During this phase, a spark jumps on the spark plug, igniting the compressed mixture. After ignition, the mixture begins to expand and the piston moves downwards to its bottom dead center.

4. Výfuk - Počas tejto fázy sa otvoria výfukové ventily, ktoré umožnia dostať sa výfukovým plynom von z valca. Na konci expanzie je tlak vo valci vyšší ako atmosférický tlak, vďaka čomu sú výfukové plyny vytláčané z valca von. Zvyšné výfukové plyny zas vytlačí piest pri pohybe k hornému úvratu. Aby sa však zlepšilo vyprázdňovanie valca, zatvárajú sa výfukové ventily až potom, ako dosiahne piest horný úvrat a nasávacie ventily sú už otvorené.4. Exhaust - During this phase, the exhaust valves open to allow the exhaust gas to exit the cylinder. At the end of the expansion, the pressure in the cylinder is higher than the atmospheric pressure, due to which the exhaust gases are forced out of the cylinder. The remaining exhaust gases are pushed out by the piston when moving to the top dead center. However, to improve cylinder emptying, the exhaust valves are closed only after the piston reaches top dead center and the intake valves are already open.

Vznetový štvortaktný motor má nasledujúce pracovné cykly:A four-stroke diesel engine has the following duty cycles:

Princíp činnosti štvortaktného vznetového motora je veľmi podobný činnosti štvortaktného zážihového motora. Hlavným rozdielom je fakt, že sa do valcov nasáva len čistý vzduch, do ktorého sa po stlačení a zahriatí vstrekuje nafta a vzniknutá zmes sa zapaľuje kompresným teplom.The principle of operation of a four-stroke diesel engine is very similar to the operation of a four-stroke petrol engine. The main difference is the fact that only clean air is drawn into the cylinders, into which, after being compressed and heated, diesel fuel is injected and the resulting mixture is ignited by compression heat.

1. Nasávanie - Piest sa pohybuje zo svojho horného úvratu smerom nadol do dolného úvratu, čím sa priestor nad piestom zväčšuje a zároveň sa otvoria aj nasávacie ventily, vďaka čomu sa do valcov cez nasávacie potrubie dostáva potrebné množstvo vzduchu.1. Intake - The piston moves from its top dead center down to its bottom dead center, which increases the space above the piston and at the same time opens the intake valves, thanks to which the necessary amount of air enters the cylinders through the intake pipe.

2. Kompresia - Potom, ako piest dosiahne svoj dolný úvrat, sa začne pohybovať smerom hore. Piest svojím pohybom smerom hore stláča vzduch, ktorý sa vďaka tomu zahrieva, no rastie aj jeho tlak. Tesne predtým, ako dosiahne piest svoj horný úvrat, sa do spaľovacieho priestoru vstrekne palivo, ktoré sa vznieti.2. Compression - After the piston reaches its bottom dead center, it begins to move upwards. With its upward movement, the piston compresses the air, which heats up as a result, but also increases its pressure. Just before the piston reaches its top dead center, fuel is injected into the combustion chamber and ignited.

3. Expanzia - Po vznietení zmesi tlak plynu pôsobí na piest, čím premieňa tepelnú energiu paliva na mechanickú prácu motora. Pri expanzii sa piest motora pohybuje zo svojho horného úvratu smerom do dolného úvratu.3. Expansion - After the mixture is ignited, the gas pressure acts on the piston, which converts the thermal energy of the fuel into the mechanical work of the engine. During expansion, the engine piston moves from its top dead center to its bottom dead center.

4. Výfuk - Pri poslednom cykle sa piest pohybuje zo svojho dolného úvratu do svojho horného úvratu, pričom výfukové ventily sú otvorené. Piest pohybom hore vytláča výfukové plyny cez výfukový systém do ovzdušia. K uzatvoreniu výfukových ventilov dochádza tesne predtým, ako piest dosiahne horný úvrat.4. Exhaust - On the last cycle, the piston moves from its bottom dead center to its top dead center with the exhaust valves open. By moving up, the piston pushes the exhaust gases through the exhaust system into the air. The exhaust valves close just before the piston reaches top dead center.

Pri vznetovom štvortaktom motore platí to isté ako pri zážihovom štvortaktnom motore. Potom, ako skončia všetky štyri cykly, začína pracovný obeh motora odznova.The same applies to a diesel four-stroke engine as to a petrol four-stroke engine. After all four cycles are finished, the engine's duty cycle begins again.

Konštrukcia štvortaktného motora je pri zážihovom a vznetovom vyhotovení veľmi podobná. Na kľukovom hriadeli je otočné upevnená ojnica. Druhý koniec ojnice je spojený pomocou čapu s piestom, ktorý je posuvne uložený vo valci. Horná časť valca je uzatvorená hlavou, v ktorej je vytvorený nasávací kanál uzatváraný nasávacím ventilom a výfukový kanál uzatváraný výfukovým ventilom. Činnosť ventilov je ovládaná elektronicky alebo pomocou vačkového hriadeľa, ktorý je spolupracujúci s kľukovým hriadeľom.The design of the four-stroke engine is very similar in the spark-ignition and diesel versions. A connecting rod is rotatably mounted on the crankshaft. The other end of the connecting rod is connected by means of a pin to the piston, which is slidably stored in the cylinder. The upper part of the cylinder is closed by the head, in which the intake channel closed by the intake valve and the exhaust channel closed by the exhaust valve are created. The operation of the valves is controlled electronically or by means of a camshaft that cooperates with the crankshaft.
