International Automotive Components Interview Questions and Answers

PNP and NPN sensors are used in industrial automation to detect the presence or absence of objects.

• PNP sensors source current and NPN sensors sink current

• PNP sensors are connected to positive voltage while NPN sensors are connected to ground

• PNP sensors are typically used in sourcing applications while NPN sensors are used in sinking applications

DG electricity can be generated using a diesel generator set.

• Diesel generator sets use a diesel engine to generate electricity

• Fuel is burned in the engine to produce mechanical energy

• The mechanical energy is then converted into electrical energy using an alternator

• Regular maintenance and fuel supply are essential for continuous operation

• Examples of diesel generator brands include Caterpillar, Cummins, and Generac

Control diagrams for star delta starter and reverse forward starter.

• Star delta starter: used for starting induction motors, reduces starting current by first connecting the motor in star configuration and then switching to delta configuration.

• Reverse forward starter: used for reversing the direction of rotation of a motor, achieved by changing the phase sequence of the motor windings.

• Control diagrams typically include ...read more

FIFO stands for First In, First Out, a method for managing data or inventory where the oldest items are processed first.

• FIFO is commonly used in inventory management to ensure older stock is sold before newer stock.

• In data structures, FIFO is implemented using queues, where the first element added is the first to be removed.

• Example: In a grocery store, perishable items like fruits are sold using FIFO to minimize spoila...read more

The 7 quality control tools are essential for identifying and solving quality-related issues in various industries.

• Check sheets: Used to collect and analyze data for quality control purposes.

• Control charts: Monitor process performance and identify variations.

• Histograms: Visualize data distribution and identify patterns.

• Pareto charts: Prioritize problems by their frequency or impact.

• Cause-and-effect diagrams: Identify a...read more

5s is a quality control methodology that focuses on organizing and standardizing the workplace.

• 5s stands for Sort, Set in Order, Shine, Standardize, and Sustain.

• It aims to improve efficiency, productivity, and safety by eliminating waste and creating a clean and organized work environment.

• Example: In a manufacturing plant, implementing 5s can involve sorting and removing unnecessary items, organizing tools and equipmen...read more

The 6 sigma rule is a statistical concept that aims to reduce defects and improve quality in processes.

• 6 sigma is a methodology used to measure and improve process performance.

• It focuses on reducing variation and defects in a process to achieve near-perfect quality.

• The goal of 6 sigma is to have only 3.4 defects per million opportunities.

• It uses statistical tools and techniques to identify and eliminate sources of vari...read more
