GE Transportation Interview Questions, Process, and Tips

Yes, I have worked on HHP Engines.

• HHP stands for High Horsepower.

• HHP Engines are commonly used in heavy-duty applications such as mining, construction, and marine industries.

• Power ratings of HHP Engines can vary depending on the specific model and application.

• For example, the Caterpillar C175-20 HHP Engine has a power rating of up to 4000 horsepower.

• Other HHP Engines may have power ratings ranging from 1000 to 5000 hor

Engine derate refers to the reduction in engine power output due to various factors.

• It can be caused by high altitude, high temperature, or poor fuel quality.

• Derating can be temporary or permanent depending on the cause.

• It is a safety feature that prevents engine damage and ensures reliable operation.

• Derating can be indicated by warning lights or reduced performance.

• Proper maintenance and monitoring can help prevent en

Turbocharger increases engine power by compressing air and increasing oxygen supply. Boost pressure improves engine performance.

• Turbocharger is a device that uses exhaust gases to compress air and deliver it to the engine

• It increases the density of air entering the engine, allowing more fuel to be burned and increasing power output

• Boost pressure refers to the amount of pressure above atmospheric pressure that the turbo...read more

A lubrication system diagram shows the flow of oil or grease through the engine or machinery.

• The diagram typically includes a pump, filter, oil cooler, and various lines and fittings.

• It may also show the location of oil pressure sensors and switches.

• The diagram can help identify potential issues with the lubrication system, such as blockages or leaks.

• Examples of lubrication system diagrams can be found in service manua

The torque on cylinder head depends on the make and model of the engine.

• The torque specification can be found in the engine manual.

• It is important to use a torque wrench to ensure proper torque.

• Over-tightening can cause damage to the engine, while under-tightening can cause leaks.

• Different engines may have different torque specifications for the same cylinder head.

• The torque may also vary depending on the type of bolts

A battery is a device that stores chemical energy and converts it into electrical energy. Charging circuit is used to replenish the energy in the battery.

• A battery is composed of one or more electrochemical cells that convert stored chemical energy into electrical energy.

• The charging circuit is responsible for supplying the necessary electrical current to reverse the chemical reactions within the battery and restore it...read more
