DSK Toyota Senior Service Advisor Interview Questions and Answers

Two stroke engines have a power stroke every revolution, while four stroke engines have a power stroke every other revolution.

• Two stroke engines have a simpler design with fewer moving parts.

• Four stroke engines are more fuel efficient and produce less pollution.

• Examples: Two stroke engines are commonly found in chainsaws and dirt bikes, while four stroke engines are used in cars and motorcycles.

Air fuel ratio of diesel engine is the ratio of air to fuel in the combustion process.

• Air fuel ratio is typically around 14:1 for diesel engines.

• Optimal air fuel ratio ensures efficient combustion and engine performance.

• Lean air fuel mixture (more air, less fuel) can improve fuel efficiency but may lead to higher NOx emissions.

• Rich air fuel mixture (more fuel, less air) can improve power output but may lead to higher e...read more

The alternator is a crucial component in a car's electrical system, responsible for charging the battery and powering the electrical components while the engine is running.

• Converts mechanical energy from the engine into electrical energy to charge the battery

• Powers the electrical components of the car while the engine is running

• Regulates the voltage to ensure a consistent power supply

• Typically located near the front of...read more

The alternator in a car is responsible for converting mechanical energy into electrical energy to power the vehicle's electrical systems.

• The alternator charges the battery while the engine is running

• It powers the electrical components of the car such as the lights, radio, and air conditioning

• If the alternator fails, the car may not start or the battery may die

• Common signs of alternator issues include dimming lights, st

The differential in a vehicle allows the wheels to rotate at different speeds while maintaining traction.

• Differential is a gear train that allows the wheels on an axle to rotate at different speeds.

• It is necessary because the inner and outer wheels of a vehicle turn at different speeds when going around a corner.

• There are different types of differentials such as open, limited-slip, and locking differentials.

• Open differ...read more

Seeking new challenges and opportunities for growth.

• Desire for new challenges and opportunities for growth

• Company restructuring led to changes in job responsibilities

• Seeking a more collaborative work environment

Supportive and inclusive of LGBTQ community

• Believe in equality and respect for all individuals regardless of sexual orientation or gender identity

• Advocate for LGBTQ rights and support diversity in the workplace

• Promote a safe and inclusive environment for LGBTQ individuals to thrive

• Recognize the importance of representation and visibility for LGBTQ community

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.

• Th...read more

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
