V.S.T Tillers Tractors Senior Engineer Interview Questions and Answers for Freshers

Compilation process involves several steps to convert source code into executable code.

• Preprocessing: Includes header file inclusion, macro expansion, and conditional compilation.

• Compilation: Translates source code into assembly code.

• Assembly: Converts assembly code into machine code.

• Linking: Combines object files and libraries to create an executable file.

• Loading: Loads the executable file into memory and prepares it

Engine working refers to the process of converting fuel into mechanical energy to power a vehicle or machine.

• Fuel is ignited in the combustion chamber, creating high-pressure gases that push the pistons down.

• The pistons are connected to the crankshaft, which converts the up-and-down motion into rotational motion.

• The rotational motion is transferred to the transmission, which then powers the wheels or other machinery.

A 4-stroke diesel engine works on the principle of internal combustion, where fuel is ignited by compressed air.

• Intake stroke: air is drawn into the cylinder

• Compression stroke: air is compressed, raising its temperature

• Power stroke: fuel is injected and ignited, causing a rapid expansion of gases and pushing the piston down

• Exhaust stroke: the piston pushes the exhaust gases out of the cylinder

• Diesel engines are more fu...read more

There are several types of engines, including internal combustion, electric, hybrid, and rotary engines.

• Internal combustion engines are the most common and include gasoline and diesel engines.

• Electric engines use electricity to power the vehicle and are becoming more popular.

• Hybrid engines combine both internal combustion and electric engines.

• Rotary engines are less common and use a unique design to generate power.

• Othe...read more

A value timing diagram is a graphical representation of the timing relationship between input and output signals.

• It shows the timing relationship between input and output signals

• It is used to analyze the behavior of digital circuits

• It helps in identifying timing violations and optimizing circuit performance

• It consists of a horizontal time axis and vertical voltage axis

• Examples include setup and hold time diagrams for f

The 3 main engine systems are fuel, ignition, and cooling.

• Fuel system: responsible for delivering fuel to the engine

• Ignition system: responsible for igniting the fuel-air mixture

• Cooling system: responsible for regulating the engine temperature

• Examples: gasoline engine, diesel engine, hybrid engine
