Internal combustion engine different properties

Internal electrocution locomotive different properties develop in detail, the differing operating moots inherent in two unrelated i.c ( congenital combustion) locomotivesAn internal combustion locomotive differs in operation depending on which dismiss it is be run of because gasoline and diesel motor scram different properties. diesel locomotive And Its PropertiesDiesel is obtained from crude oil via 3 processes separation, upgrading and conversionThe initial boiling spot for diesel is round 125 degrees (c)and its final boiling point around 400 degrees (c)Diesel similarly contains sulphur the more than sulphur it contains the more electricity it hind end conduct insufficient electric conductivity is potentially a safety hazard as it could lead to a pee-pee up of static charge during the bulk transfer of fuel yet its not very high risk in a labour fomite because of the low velocity of fuel that gets transferredNeeds to be scoot in to the combustion chamber at high thrust so that the summate of diesel is always the same and so that the correct amount of diesel reaches each combustion chamber at the correct fourth dimensionDiesel is not flammable this is why a glow trollop is required to heat the diesel up on a iciness start this is also another reason why diesel had to be forced into the combustion chamber under high pressure gasoline And Its PropertiesHas and lower boiling point than diesel Petrol is flammable and thither for can be ignited using a spark strange dieselPetrol is not as dense as diesel they both are produced from crude oil moreover is more nifty than dieselReasons for differences in an ic engine running on gasoline in oppose to dieselBecause of the different properties in petrol and diesel the parts and configuration of ic engines and the way they are run varies. For case a modern diesel will have a fuel rail located on top of the combustion chamber which depending on how many cylinders will have a row of high press ure injectors for instance a 4 cylinder would have 4 injectors unitary per cylinder. Now this would be the case in a petrol engine solely the injectors would operate under much lower pressures and therefore the pipes that go to each injector are different. Often the pipes leading from the fuel pump to the injector on a diesel engine are made out of copper as it is a material that handles well under pressure but in a petrol engine the pipes are commonly sightly rubber or PVC depending on the requirements they need to meet. A diesel engine only take in air, and shortly before the apex of the suns way amount of compression, a small quantity of diesel fuel is sprayed into the cylinder via a fuel injector at high pressure that allows the fuel to flat ignite due to higher pressures and heat. A petrol engine uses a different method to ignite the fuel source because petrol is flammable it can be ignited using a spark the petrol is injected into the combustion chamber under relatively l ow pressure but before it reaches the chamber it becomes in contact with a spark drudge which ignites the fuel forcing the diver polish this causes compression which forces the plunger back up creating the stroke in this case a 4 stroke cycle. both ic engines in this case use the 4 stroke cycle the only difference universe the way the fuel is ignited, which in turn gives u the combustion stroke which starts the 4 stroke cycle.Task 2- approximate the vehicle design, and therefore the instruction execution implications of a particular choice of engine configuration and layoutFerrari use a ironical sump system in appose to a baffled sump system which is more usually found on an ic engine. This is because a baffled sump takes up a lot of space and has a large depth this is because in a baffled sump system all the oil is stored in one place. A run dry sump works by having a separate oil artificial lake. There is a shallow oil reservoir usually mount on the underneath of the eng ine and thusly a separate oil tank is located somewhere else in the engine bay. A pump helps supply the reservoir tank with oil from the important oil tank and then a scavenge pump helps to change the oil back to the oil tank via pipes ensuring a constant turn tail of oil gets supplied to the engine at all times.The main advantage of the dry sump system is that it means an engine can be mounted lower to the ground as meaning the car can have a lower centre of gravity improving the cars overall performance and handling this is why dry sump systems are most normally found on race cars and performance cars. There are downfalls to dry sump systems they require more piping and to oil reservoirs meaning the manufacturing cost are higher than they would be if a baffled sump system. Ferrari also mount their engines primarily in the middle of their cars the main reason for this being that you can achieve a perfect 50 50 incubus distribution meaning that the cars handling is as good as i t can be as all the weight is shared across the underframe evenly. It also means that under heavy breaking the car usage nose dive because there isnt more weight in the scarecrow of the car than the rear. The main downfall to having a middle mounted engine is that u can only really fit 2 put into a car and that you lose a lot of the practically of the vehicle but the gain in the performance of a vehicle with a middle mounted engine more than makes up the practicality lost.task 3- explain the bleed, operational and construction of the main internal functions/ assemblies of a particular pillowcase of I.C engineIn an ic engine there are some(prenominal) different components which are critical for the running of the engine here I am going to name and explain what the main internal components do and there licks.Valves- in a common 4 cylinder 16valve engine there is 4 valves per cylinder mean 4valves times 4 cylinders 16 valves. 2 of these valves are breathing in valves and the other 2 valves are subject valves, the inlet valves allow the injected petrol or diesel to enter the combustion chamber at regular intervals these intervals are mulish by the cam sleep together. The freeing valve does the opposite of the inlet valve when the outlet valve opens it gets rid of the gases and deposits created from the 4 stroke cycle.Pistons-the function of the piston is to compress the mixed bag that enters the combustion chamber this happens because as the mix of fuel enters that enters the chamber when ignited forces the piston from tdc down to bdc then as the piston starts to rise from bdc back up to tdc this creates compression then as the piston rises the outlet valves open and the gases causes from the combustion stroke exit by means of the valves under pressure and are exited from the car via the exhaustDrive brawl- A belt is a loop of flexible material used to standoff the 2 shafts of an engine together mechanically. In an ic engine the belt has to be t imed so that both the cam shaft and the crack shaft are turning at the exact rite time so they can carry out their function efficiently.Cam shaft- The cam shaft only function is to ensure that the valves open and close at the correct time it is fundamentally a coat shaft that has metal pear tree shape components fixed along it at regular intervals the reason for these pear shaped metal components is that when the cam shaft is turning via the drive belt each pear shaped component corresponds with the rocker cover of the a valves the pear shaped component pushes one side of the rocker cover down which compresses a jet located underneath the rocker cover which in turn pushes the inlet valves open. The cam shaft then continues to turn allowing the inlet valves to close. Then the other pear shaped components correspond with the other side of the rockers cover then when they come in contact with the rocker cover push down the outlet valves this is all done to a precise timing which is determined from the drive belt.Crank shaft- The barbarian shaft is what determines the movement of the pistons the shaft is usually driven from the drive belt and the humongous end of the cam rod connects the piston to the shaft this shaft converts the rotational motion of the shaft into a vertical motion so that the pistons can move up and down in the cylinders.Cam rod- the cam rod is the rod that connects the piston to the crack shaft it does this via a big end and a small end the big end connects to the crank shaft and the little end connects the head of the piston to the rod the piston heads are usually connect to the cam rod using a pin.
