What is advantages four stroke engine?
When comparing to a two-stroke engine, the four-stroke engine has the following advantages.Fewer emissions. Since the crankshaft has its own oil reservoir there is no need to add oil to the fuel, meaning there is no oil burned in the fuel.Better fuel consumption. The four-stroke engine complete a full cycle in four-stroke. This gives it greater control over which ports open at which times. On a two stroke engine, fuel and air is being forced into the cylinder while exhaust is being forced out, this causes some fuel and air to flow directly through the cylinder and out the exhaust. Four-stroke engines are also directly fuel injected which allows greater control over fuel delivery.Longevity. The four-stroke engine has a lower power to weight ratio than the four-stroke engine. In this respect, the engine components aren't pushed as hard as a two-stroke. This allows them to last longer.
Describe how a four stroke engine works?
The strokes of a four stroke engine are intake, compression, power, and exhaust. The engine takes in the fuel, compresses it, uses it for power, and then the excess fuel comes out the exhaust.
Advantages and disadvantages of four stroke petrol engine?
One advantage of having a four stroke petrol engine is the fuel economy. A disadvantage of the engine is in the cold weather they are harder to start.
Can you use 2 stroke fuel in a four stroke motorbike?
Fuel is fuel. The fuel only changes when you add 2 stroke oil to it. You can burn it in a 4 stroke engine, might smoke some, but it is not recommended for your normal outing.
What is the difference between a 2 stroke and a 4 stroke lawn mower engine?
Four-stroke engines have a spout where you add oil to the engine. On two-stroke engines, oil has to be added to the fuel. (Four-stroke and two-stroke are also called four-cycle and two-cycle, respectively).
What is the fuel oil mixture for an older Briggs and stratton lawn mower?
Briggs and Stratton made almost exclusively four stroke engines. There is no fuel oil mixture for a four stroke engine. Are you sure you have a two stroke engine by Briggs and Stratto? rhg
What are the four strokes to a four stroke engine?
The four strokes of a four-stroke engine are the intake, compression, power, and exhaust strokes. During the intake stroke, the engine draws in air and fuel. The compression stroke then compresses this mixture, followed by the power stroke, where the spark plug ignites the mixture, generating power. Finally, in the exhaust stroke, the engine expels the burnt gases from the combustion process.
Oil in fuel mix for Four-stroke engine?
Usually none at all.
What are two types of oiling systems for a four stroke engine?
external cooling and with fuel
Why fuel consumption is less in 4 stroke engine then in 2 stroke engine?
Why the fuel consumption is less in 4 stroke engine as compared to 2 stroke engine
In 4 stroke what is injected at suction?
A four stroke engine has four basic operations within the engine. It has Intake, compression, power and exhaust strokes. During the intake, or suction stroke, a mixture of fuel air is injected into the cylinder.
How many intake events are there in one revolution of a four cylinder engine?
There is only one intake stroke in a four-stroke engine. The other three strokes are compression, power, and exhaust. The intake stroke is a down stroke of the piston in which fuel is drawn into the cylinder while the fuel intake valve is open. The next stroke is the compression stroke in which the valves are closed and the fuel is compressed for combustion. The following stroke is the power stroke - a downward stroke of the piston after fuel combustion that drives the crankshaft. The final stroke is the exhaust stroke, an upward stroke of the piston as the exhaust valve opens to relieve the exhaust fuel fumes.
