GE Transportation Service Engineer Interview Questions, Process, and Tips

Q1. Disel engine combustion process
Ans. 
The diesel engine combustion process involves the ignition of fuel injected into the combustion chamber by compressed air.
• Diesel fuel is injected into the combustion chamber at high pressure

• The air in the combustion chamber is compressed by the piston, leading to high temperatures

• The high temperature air ignites the fuel, leading to combustion and the generation of power

• The combustion process in diesel engines is more

Q2. What is two & four stroke engine.
Ans. 
A two-stroke engine completes a power cycle in two strokes of the piston, while a four-stroke engine completes it in four strokes.
• Two-stroke engines have a simpler design with fewer moving parts compared to four-stroke engines.

• Two-stroke engines typically produce more power for their size but are less fuel-efficient and emit more pollution.

• Four-stroke engines are more common in cars, motorcycles, and larger machinery d...read more

Q1. What is the difference between star and delta connection.
Ans. 
Star and delta are two types of connections used in three-phase systems.
• Star connection has neutral point and is used for small loads.

• Delta connection has no neutral point and is used for high loads.

• Star connection has lower voltage and higher current while delta connection has higher voltage and lower current.

• Star connection is more reliable and easier to maintain than delta connection.
