Top 40 Automobile Technology mechanical interview questions and answers for Fresher Beginners


hello everyone welcome to GTECH techno solution Private Limited now we are going to see about the automobile technology and it’s interview tips [Music] you [Music] so we have the question what are the functions of a flame the functions of a frame are to support the chases components and the body and to withstand static and dynamic loads without undue deflection or distortion to carry the load of passengers always we can say to carry the goods carried in the body so these are considered to be the functions of a frame so it supports its withstand it carries the load and other things [Music] we’ll want to the next question lists out the various materials used in the construction of chasis frames [Music] the materials are low carbon steel high carbon steel and alloy so if you see about the low carbon steel it has the range of 0.18 or 0.20 percentage of carbon content in terms of high carbon steel the carbon content will be 0.25 percentage and in terms of alloy steel with alloying elements like nickel and chromium will be there so these are considered to be the various materials used in the construction of charge strains let’s move to the next question write down any two main sections of physical construction the two sections are charges construction and bony construction we’ll go to the next question what are the two types of physical suspensions the first one is rigid axle suspension and second one is independent suspension [Music] we have a next question what is mean by steering ratio [Music] steering ratio is defined as the ratio of the angle turned on the steering wheel to the angle toward by the sub axle you can see the steering wheel over here [Music] let’s move to the next question what are the functions of a gearbox the functions of a gearbox are the gearbox have to provide talk.you multiplication annex functionals it has to provide the means to reverse a lip curl and the top function is all about you have to provide neutral position so these are the functions of a gearbox [Music] we have the next question why do you need a gearbox the answer for the reason of having the gearbox is all about when the Whizzer curl is moving on a road it asked to encounter different resistance depending upon the road surface vesical speak and Road gradient the wheel talk you required at Road beads is different for different operating conditions to satisfy this requirement a gearbox is necessary in a circle [Music] which one to the next question why is the frame narrow at friend the reason is that the frame is narrowed and a friend in order to provide a better steering lock this also provides smaller turning circle radius [Music] let’s move to the next question why are these five members of the frame-up SPECT at different places the framers upswept at the rear and friend to accommodate the movement of the accidents due to springing it also keeps the charges height low let’s move to the next question name few components of engine the components of engine are cylinder block cylinder heads crankcase cylinder piston connecting draw crankshaft camshaft spark veil slug and the fuel injector so these are the components of an engine [Music] [Music] we have a next question what are the types of friends [Music] the types of frames are ladder type frame X type frame parameter type frame and backbone type frame so these are the types of friends you can see the depiction of how the ladder type X type parameter type and the backbone type frame over here so the next question is list the various manufacturers of automobile oryx in India the various manufacturers of automatics in India are passenger vehicles heavy commercial vehicles three videos three wheelers and the two leaders some of the examples of passenger vehicles are Model T Hyundai and so on some of the examples of heavy commercial is occurs or Tata assure plan like Ashok Leyland and so on some of the examples of three wheelers are or two an Ingo and so on and some of the examples of two wheelers are Bajaj hero in dog TV isuzu K and so on [Music] we got the next question over here see the major types of automobiles according to the Pew will used the major types of automobiles in terms of human usages diesel engines petrol engines and gas engines if you consider diesel engines the fuel use this see I that is compression ignition engine types in terms of petrol engines it will be spark ignition that is s-i engines in terms of gas engines it will be either spark ignition or compression ignition mode so this is how the major types of automobiles are categorized according to the fuel’s which is used in that [Music] so the next question is what is mean by the term chasis a complete physical without a body structure is known as chassés it comprises of basic structure power unit transmission system controls and oxy arrays we have the next question how automobiles are classified into different types the automobiles are classified into different types based on [Music] make a model fuel based on the body style based on the number of vehicles based on the drive and based on the transmission so based on these categories the odd moments are getting to be classified [Music] here we go over the next question what are the functions of piston rings the function is nothing but to provide a gas tight seal between the piston and the cylinder liners to prevent the escape of gases from top side of the piston to the underside so this is the main function of the piston ring we have the next question what are the two types of piston rings the first type is compression rings and the second type is oil rings let’s move to the next question what are the different methods of engine cooling the different methods of engine cooling are our cooling oil all water cooling you can see the depiction of how the our cooling and the water cooling that is also called as oil cooling over here so these are the depiction of the different methodologies of engine engine cooling [Music] we have a next question what are the advantages of AD cooled engines the advantages are less weight power ratio and does not require any radiator or water pump and they’ll not be any antifreeze agents that is required for it and it will not be having any sort and mud deposits in the system and the last advantage that our cold engines are cheaper we have the next question what is clearance volume and what are its affects the volume amout of piston when it reaches the TDC that is top dead center is known as clearance volume and the clearance volume is inversely proportional to the compression ratio we have a next question what is the function of piston connecting rod crankshaft and cylinder head the function of a piston is that the piston assembly transfers the force from the power stroke to the crankshaft the function of a connecting draw is that it converts a reciprocating motion of piston into rotating motion of crankshaft and the function of cylinder head is that cylinder head acts as a top cover to the cylinder block the vaults are placed in the cylinder head in an overhead wall engine the next question is that state the merits of water cooling system the merits of water cooling system our cooling efficiency is better more uniform cooling will be there and the engine operation is silent in nature and the last merits is that it does not need an impeller or a bowl [Music] let’s move to the next question state the develops of water cooling system the limits of water cooling systems are mode number of components like radiators water pump antifreeze agents needed the antifreeze agents are excellent glycol and methanol more salt and muck deposition this system so these are considered to be the B merits and also the engines are costlier so all these are emphasizing about the limits of the water cooling system it needs more number of components it needs the antifreeze agents and more soils in one deposition so these are considered to be the most frequently considered the minutes of the water cooling system [Music] we have a next question what is the purpose of lubricating system if you see about this one the purpose of lubrication system or lubricating system is that to supply the lubricating oil between the moving parts of the engine in order to reduce the friction and to provide the cooling effect in order to carry away the deposits for due to wear and tear so these are considered to be the main purpose of lubricating system here we go over the next question what is mean by turbocharging increasing the density of inductive charge or AD by using a compressor which gets its power from the exhaust driven turbine is said to be called as turbo charging you can see the depiction of turbo charging over here and how it’s giving to be exhaust [Music] we’ll go to the next question what are the various pollutants in internal combustion engine the various pollutants are hexie that is hydrocarbon seewho carbon monoxide and go eggs nitrous oxide particulate x42 that is sulphur dioxide and the final one has co2 this is carbon dioxide so these are considered to be the various pollutants in internal combustion engine [Music] let’s move to the next question what is mean by the dog conventional ignition system the answer for this question is that the conventional ignition system gets its electrical voltage either from battery or dynamo which will be boosted to a very high voltage due to this spark is produced in the cylinder to cumbers the mixture you can see the depiction of the ignition system over here in a conventional manner [Music] here we go the next question what is the function of a spark plug the spark plug is a device that produces the electric spark in order to ignite the compressed ad fuel mixture inside the cylinder you can see this spark plug over here we have a next question what are the functions of turbo charges the functions of the turbo charges are to produce more power from the same sized engine and the second function is that it provides the altitude compensation and the third function of the turbo charges are to improve more complete combustion and hence less emission so these are the points which are emphasizing and declining about the function of turbo charges [Music] let’s go to the next question what is mean by supercharging in terms of automobile technology supercharging is said to be considered as a process of increasing the density of inducted charge or a which is called as simply supercharging you can see how is super charming principle is emphasized over here the depiction apart from dirt supercharging is performed for the foreign reasons the reasons are that to produce more power from the same sized engine and also it is performed to provide altitude compensation and also to improve more complete combustion and hence less emission [Music] let’s see the next one what is mean by bleeding off brakes the process of removing earth from the hydraulic brakes is known as bleeding of brakes you can see the systemic depiction of the bleeding of brake system over here and it’s processing the next question is as follows what’s the purpose of toe-in and toe-out the purpose of providing a toe-in and toe-out this straight-line stability of the vehicle after negotiating a turn you can see clearly how the toe out and toe Hin is implemented in the present dated over here [Music] let’s see the next question define custard and Chamba if you see about castor the print of the kingpin from the vertical reference line when viewed from size is set a bit called as caster [Music] camber is the one if you see here the chanter angle is the inward or outward tilt of the vehicle related to these vertical reference so this is called as rubber we have the next question what is mean by hybrid physical a hundred visitors of the Hickel that uses two are more distinct power sources to move the vehicle the term most commonly refers to hybrid electrical currents it is simply called as HCV so the throw which is most commonly referred to hybrid electric vehicles which combine an internal combustion engine and one or more electric motors [Music] let’s see the next question what are the advantages of fuel cells this was one such question which is highlighted in anti PC and limits a fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction of positively charged hydrogen ions with oxygen are another oxidizing agent the Wylie by-product from the fuel cell is either water our co2 which can be safely disposed I also the fuel cell is compact in size as long as there is supply of fuel there will be generation of electricity so these are considered B’s most examples of some of the advantages of fuel cells [Music] thank you for watching this from G ticket no solution Private Limited [Music]
