2 stroke petrol enginezakvan kadva
油
A two-stroke petrol engine completes the combustion cycle in two strokes of the piston rather than four as in a four-stroke engine. In a two-stroke engine, the intake and exhaust strokes are eliminated and ports instead of valves are used, with the exhaust gases driven out by the fresh fuel charge entering near the end of the power stroke. Everything a four-stroke engine does over two revolutions, a two-stroke engine accomplishes in one revolution, with the fuel-air mixture entering the crankcase and being compressed and ignited directly in the cylinder. While smaller, lighter and cheaper than a four-stroke engine, two-stroke engines wear parts faster, are less fuel efficient, and more polluting.2 stroke petrol engine

The document discusses diesel engines, including their definition, construction, workings, types, and efficiency calculations. A diesel engine ignites fuel injected into the combustion chamber via heat from compressed air, rather than a spark plug. The two main types are two-stroke and four-stroke engines. Two-stroke engines complete a cycle in one revolution while four-stroke engines require two revolutions. The four strokes of a four-stroke diesel engine are intake, compression, power, and exhaust.dieselengine-141119065739-conversion-gate01.pdf

The document discusses the six stroke engine, which differs from a four stroke engine by having two power strokes - one from fuel and one from steam or air. It provides examples of six stroke engine designs and discusses the working strokes. The six stroke engine has higher efficiency than a four stroke engine but also has higher costs due to its more complex design with additional components. While promising for reducing fuel consumption and emissions, commercializing the six stroke engine faces challenges of high initial costs.History of the diesel engine

A two-stroke engine has a compression and combustion stroke in each revolution, while a four-stroke engine has separate intake, compression, combustion, and exhaust strokes. In a two-stroke, oil is mixed with gasoline to lubricate parts. Two-stroke engines are lighter and more powerful but less efficient and produce more pollution than four-stroke engines due to exhausting unburned fuel. The piston acts as both a valve and plunger in two-stroke engines.internal compustion.pptx

An internal combustion engine uses combustion of fuel to drive pistons that convert the energy to mechanical energy. The first modern internal combustion engine was created by Nikolaus Otto in 1876. There are different types of internal combustion engines classified by fuel, strokes, ignition, cycle, number of cylinders, and cooling method. The key parts include the cylinder, piston, connecting rod, valves, crankshaft, and flywheel. A four-stroke engine intakes air/fuel, compresses it, combusts it to push the piston, and exhausts gases over two revolutions, while a two-stroke engine does this in one revolution.ICE CH1 2022-2023.pptx

The main components of a steam power plant are a boiler, turbine, condenser, cooling tower, and pump. The Rankine cycle consists of four processes: (1) isentropic compression in the boiler, (2) isobaric heating in the boiler, (3) isentropic expansion in the turbine, and (4) isobaric cooling in the condenser. Heat added in the boiler is converted to work output by the turbine, which is then used to run a generator. The vapor from the turbine is condensed back into a liquid in the condenser and pumped back to the boiler to repeat the cycle.2-stroke cycle gasoline engine

- Two-stroke engines complete the combustion cycle in two strokes of the piston rather than four strokes, as in four-stroke engines. They rely on crankcase compression or a blower to induct fresh air and remove exhaust gases, rather than separate intake and exhaust strokes.
- There are different types of two-stroke engines based on the scavenging method (crankcase or separately scavenged), scavenging process (cross flow, loop, uni-flow), and port timing (symmetrical or unsymmetrical).
- In a crankcase-scavenged engine, the piston helps induct fresh air into the crankcase and transfers it into the cylinder, where it scavenges out exhaust gasesSplit engine

The Scuderi split cycle engine separates the four strokes of a conventional engine into two cylinders. In one cylinder, intake and compression occur. The compressed air is then transferred to the second cylinder where combustion and exhaust take place. This design allows combustion to occur after top dead center, improving efficiency by eliminating losses from recompressing gases. It provides advantages like flexibility, reduced friction, and improved breathing compared to conventional engines. However, challenges include preventing heat buildup in the power cylinder and ensuring durability of the crossover valve. Overall, the Scuderi split cycle engine can achieve over 40% thermal efficiency and significantly reduce fuel waste and emissions.Module 3a.pdf

Supercharging increases the air density in an internal combustion engine to provide more power. It works by compressing the air intake using a supercharger or turbocharger. There are three main types of compressors - positive displacement, axial flow, and centrifugal. Supercharging allows an engine to produce more power from the same displacement by permitting greater air intake. It improves engine performance but requires power to drive the compressor, reducing overall output.Recently uploaded (20)

Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method, we invent to deliver products, whether physical or virtual, we reinvent productivity philosophies to go alongside them.
But which of these approaches works? DORA? SPACE? DevEx? What should we invest in and create urgency behind today so we dont have the same discussion again in a decade?How Discord Indexes Trillions of Messages: Scaling Search Infrastructure by V...

World Information Architecture Day 2025 - UX at a CrossroadsJoshua Randall
油
User Experience stands at a crossroads: will we live up to our potential to design a better world? or will we be co-opted by product management or another business buzzword?
Looking backwards, this talk will show how UX has repeatedly failed to create a better world, drawing on industry data from Nielsen Norman Group, Baymard, MeasuringU, WebAIM, and others.
Looking forwards, this talk will argue that UX must resist hype, say no more often and collaborate less often (you read that right), and become a true profession in order to be able to design a better world.Unlocking DevOps Secuirty :Vault & Keylock

- 1. INTRODUCTION In 1878, Dugald-clerk, a british engineer introduced a cyle which could be completed in two stroke of piston rather than four strokes as is the case with the four stroke cycle engines. the engines using this cycle were called two stroke cycle engines. In this engine suction and exhaust strokes are eliminated. Here, instead of valves, ports are used. The exhaust gases are driven out from cylinder by the fresh charge of fuel entering the cylinder nearly at the end of the working stroke.
- 2. 2 Stoke Engines Everything a 4 stroke engine does in 2 revolutions a 2 stroke engine does in 1 revolution of the crankshaft. How to identify 2 stroke engine from outside: Exhaust port in center of cylinder Small crankcase
- 3. 2 Stoke Engines part names Combustion chamber Cylinder Exhaust port Intake port Piston Connecting Rod Crankshaft Crankcase Reed valve Transfer port Still uses a flywheel (not shown)
- 4. WORKING OF 2 STROKE PETROL ENGINE: FUEL INTAKE: Piston moves BDC to TDC Reed Valve Is sucked open Air/Fuel/Oil mixture sucked into crankcase
- 5. COMPRESSION STROKE Piston moves TDC To BDC Reed Valve sealing Air/Fuel/Oil mixture is now pressurized in crankcase Air/Fuel/Oil mixture squirts into cylinder because of crankcase compression
- 6. COMBUSTION & EXHAUST STROKE Air/Fuel/Oil mixture is ignited in cylinder Reed valve close Every time the piston reaches TDC, there is another power stroke.
- 7. P-V diagram for 2 stroke petrole engine Port timing diagram
- 9. Advantages of 2 stroke petlrol engine: Smaller/lighter Cheaper Less friction No oil to change Quicker acceleration Operate at different angles
- 10. Disadvantages of 2 stroke petlrol engine: The lack of a dedicated lubrication system means that the parts of a two-stroke engine wear a lot faster. Two-stroke engines do not use fuel efficiently, so you would get fewer miles per gallon. Two-stroke engines produce a lot of pollution -- so much, in fact, that it is likely that you won't see them around too much longer.
