Kia Motors Mechanical Technician Interview Questions and Answers

Q1. Obd full form in vehicle
Ans. 
On-Board Diagnostics
• On-Board Diagnostics (OBD) is a system in vehicles that monitors the performance of the engine and emissions systems.

• It helps to identify issues and malfunctions by providing codes that can be read with a diagnostic tool.

• OBD systems have evolved over the years, with OBD-II being the current standard in most vehicles.

• Examples of OBD codes include P0300 for random misfire and P0420 for catalytic conve

Q1. What is the capacity of diesel and petrol
Ans. 
Diesel has higher energy density than petrol, resulting in better fuel efficiency.
• Diesel has a higher energy density than petrol, meaning it can provide more energy per unit volume.

• Petrol is more volatile and burns faster than diesel.

• The capacity of diesel and petrol tanks in vehicles can vary depending on the size of the vehicle and its fuel efficiency.

• For example, a typical car may have a petrol tank capacity of arou...read more

Q2. Difference b/w petrol engine & diesel engine
Ans. 
Petrol engines use spark ignition, while diesel engines use compression ignition.
• Petrol engines use a spark plug to ignite the fuel-air mixture, while diesel engines rely on compression to ignite the fuel.

• Petrol engines are lighter and more responsive, while diesel engines are more fuel-efficient and have higher torque.

• Petrol engines are more common in cars and motorcycles, while diesel engines are often used in trucks

Q3. What is meant by LNTD
Ans. 
LNTD stands for Logarithmic Mean Temperature Difference.
• LNTD is a term used in heat transfer calculations to determine the overall temperature difference between two fluids in a heat exchanger.

• It is calculated using the formula LNTD = (ΔT1 - ΔT2) / ln(ΔT1 / ΔT2), where ΔT1 and ΔT2 are the temperature differences at the two ends of the heat exchanger.

• LNTD is important in designing efficient heat exchangers to maximize h...read more

Q3. What is the obsolete angle of impulse turbine?
Ans. 
The obsolete angle of impulse turbine is the angle at which the blades are set in relation to the direction of the water flow.
• Obsolete angle is typically around 20-22 degrees for impulse turbines.

• It determines the efficiency and performance of the turbine.

• Incorrect angle can lead to reduced power output and efficiency.

• Examples: Pelton wheel, Turgo turbine.

Q4. What is the blade efficiency of impulse turbine?
Ans. 
Blade efficiency of impulse turbine is typically around 80-90%.
• Blade efficiency is a measure of how effectively the blades of a turbine convert the kinetic energy of the fluid into mechanical energy.

• It is calculated as the ratio of the actual work done by the blades to the work that would be done if the fluid were to expand isentropically.

• Blade efficiency for impulse turbines is generally higher than reaction turbines,...read more

Q5. What is the efficiency of impulse turbine?
Ans. 
The efficiency of an impulse turbine is typically around 70-90%.
• Efficiency is calculated as the ratio of actual work output to the theoretical work input.

• Impulse turbines have high efficiency due to the fact that the energy transfer occurs in stages.

• Efficiency can be affected by factors such as blade design, operating conditions, and maintenance.

• Examples of impulse turbines include Pelton wheel and Turgo turbine.
