How many strokes are in a 2 cycle engine?
Cycle means the number of piston strokes for a complete cycle. 2 stroke= 2 cycle.
How does a four stroke engine work?
A four stroke engine has four cycles. Intake cycle, compression cycle, power cycle, and exhaust cycle. Each corresponds to one full stroke of the piston; therefore, the complete cycle requires two revolutions of the crankshaft to complete.Here is a brief explanation on how it works.Intake cycleThe intake valve opens, the piston moves downward and fuel and air is sucked into the cylinderCompression cycleThe Intake valve closes and the piston moves upward, compressing the fuel and air mixture.Power cycleA spark plug ignites the fuel/air mixture and the piston is forced downwards.Exhaust cycleThe piston moves upward and the exhaust valve opens, letting the fumes out of the cylinder.
What does 2 cycle and 4 cycle engines mean?
A 2 cycle engine's piston cycle twice. One compression stroke and 1 exhaust stroke. A 4 cycle engine cycles four times before its exhaust stroke.
Name the four piston strokes of a four cycle engine?
Intake, Compression, Power and Exhaust
When the piston is at top dead center and both valves are closed what engine stage is this in?
This is the beginning of the power stroke in engine operation cycle.
Does a 2 cycle engine need oil?
A 2-cycle engine requires a fuel/oil mixture. The ratio of oil to gasoline depends on the manufacturer's specifications for your particular engine.
Why 3-stroke engine does not exist?
Because a piston travels up and down the bore 2 or 4 times a cycle.
How does a two cycle engine work?
The piston sucks the fuel in from underneath through the reed cage and its forced up the holes in the side of the cylinder to the top of the piston, then it ignites and goes out the exhaust
What is the main working cycle of a v8 engine?
it consist of 8 piston in v shape that are attach to the crankshaft and the rest of the process is same compare to the other engine
What is an open combustion chamber?
That refers to the area where a piston goes un and downin a 4 or 2 cycle engine and burns the fuel it has pumped into that chamber compressed by the piston and ignaited by the spark plug.
Describe the position of the intake and exhaust valves during most of the power stage in four-cycle gas engine?
All right. Well, let's start from the end of the exhaust cycle (piston is up). The intake valve opens as the piston goes down, sucking in the fuel/air mixture. The valve closes when the piston reaches the bottom. As the piston makes its way back up, it compresses the mixture and near the top the spark plug ignites the mixture. This explosion sends the piston shooting down again and as it comes back up, the exhaust valve opens and the piston shoves waste gasses out of the engine. Then that valve closes and the cycle starts all over again.
How does an automobile's power plant works?
I cant really understand exactly what you are saying but if you are talking about the motor it varies upon what car you have, but most engines are piston engines that have a piston on top of a rod that is on top of a crankshaft, that moves when the engine is at work, there are 2 valves per cylinder which open at certain times of the engine cycle, it starts when the intake valve opens allowing gas and air mixture to come in when the piston is pulling down it pulls the mixture in, the piston moves back up and causes compression which at the perfect timing the spark plug fires and causes a explosion in the cylinder pushing the piston back down, the exhaust valve opens and the piston moves back up pushing all the exhaust gasses out and restarting the cycle but remember there are more than one piston in a typical car engine so there are many pistons doing a cycle at different intervals keeping the engine running.
