It is a component in which it controls the flow of fuel, air and oil and makes sure the right amount is flowed into the cylinder even though they enter different points it is still controlled by the carburetor. Also when the mixture is in the cylinder it is pushed up by the piston then when the spark plug ignites causing the engine to fire.
What is the purpose of the float in the carburetor ?
The purpose of the float is to control the airflow coming in and going out and being mixed and also because it is filled with fuel as the level of fuel increases and so does the float begin to restrict the air flow coming in and going out.
What is the purpose and how does mechanical lift pump work?
The purpose or main function of the mechanical lift pump is to pump the fuel from the fuel the fuel tank to the carburetor. This kind of pump has lever that is constantly hitting the lobes of the camshaft. The lever will go upward and downward as it hits the lobe as the camshaft rotates there by causing a vaccum effect within the pump.causing a low pressure in the supply line which causes fuel to be drawn up from tank to carb.
What pressures would you get from this type of pump?
2-5 Psi
What does S.I mean ?
It means SPARK IGNITION
What does C.I. MEAN ?
It means COMPRESSION IGNITION
What is the FOUR STROKE CYCLE ?
INTAKE= Phase in which piston goes down the cylinder and at the same time the exhaust port is closed. so as piston is going down sucks in fresh air and fuel and mixes them together and prepares for nest phase.
COMPRESSION= The next phase of the four stroke cycle and the mixture is being pushed up with the movement of the piston moving upwards while the spark plug produces a spark.
COMBUSTION= In this phase the mixture has been ignited by the spark plug therefore pushing the piston down by that causing the camshaft to move.
EXHAUST= This phase is when the piston is moving back upwards to expel burnt air and fuel and in this process exhaust port is open and the and intake closed.
How does the emulsion tube work?
How does a manual and automatic choke work?
The mannual choke is a device which are more commonly found on older boats and cars, bikes. Mannual chokes work by increasing thrust or throttle(revolutions) of the motor to get it to warm up, or a working tempreture and the choke must be pressured or pushed. As for the AUTOMATIC CHOKES same principal. But they don't rely on the person driving to push or pull the choke it is controlled automatically by thremostat.
How does a vacuum fuel pump work?
The vaccum pump is a device that uses the suckition of the piston strokes to pump fuel. It also works by using a diaphram
What is the difference between diesel and petrol ?
The difference between petrol and diesel is that petrol can easily start a fire with the smallest spark and is highly flammable. As for diesel it contains more oil and and takes more then a simple spark for it to ignite. Diesel has to be warmed up before ignited.
