JBM Group Production Engineer Interview Questions and Answers

Two-stroke and four-stroke engines differ in their operation and design.

• Two-stroke engines complete a power cycle in two strokes of the piston, while four-stroke engines complete it in four strokes.

• Two-stroke engines have a simpler design with fewer moving parts, making them lighter and more compact.

• Four-stroke engines are more fuel-efficient and produce less pollution due to separate intake, compression, power, and exhaust strokes.

• Two-stroke engines require a mixture of fuel...read more

Automobile engineering is a branch of engineering that deals with the design, development, production, and maintenance of automobiles.

• It involves the study of various aspects of automobiles, including their structure, engines, electrical systems, and safety features.

• Automobile engineers work on designing and improving the performance, fuel efficiency, and safety of vehicles.

• They also focus on developing new technologies such as electric and autonomous vehicles.

• Examples of aut...read more

An internal combustion engine (IC engine) works by converting the chemical energy of fuel into mechanical energy through a series of combustion processes.

• IC engines operate on the principle of the four-stroke cycle: intake, compression, combustion, and exhaust.

• During the intake stroke, the piston moves downward, drawing in a mixture of fuel and air into the combustion chamber.

• In the compression stroke, the piston moves upward, compressing the fuel-air mixture to increase its ...read more

An internal combustion engine (IC engine) is a heat engine that converts chemical energy into mechanical energy.

• IC engine is commonly used in automobiles and other vehicles.

• It operates by burning fuel inside a combustion chamber to produce high-pressure gases that drive a piston.

• The piston's movement is converted into rotational motion to power the vehicle.

• Examples of IC engines include gasoline engines, diesel engines, and natural gas engines.

SMED stands for Single-Minute Exchange of Die, a lean manufacturing technique to reduce setup time. Manpower handling involves managing and optimizing the workforce in production.

• SMED is a methodology to reduce setup time in manufacturing processes by converting as many setup steps as possible to external (performed while the equipment is running) and simplifying internal setup steps.

• Manpower handling involves assigning tasks efficiently, training employees, monitoring perfor...read more

OEE stands for Overall Equipment Effectiveness and it measures the efficiency of production equipment.

• OEE is calculated by multiplying Availability, Performance, and Quality rates of equipment.

• It helps in identifying areas of improvement in production processes.

• For example, if a machine has an OEE of 80%, it means it is operating at 80% of its maximum potential efficiency.
