Ola Electric Mobility Service Manager Interview Questions and Answers

Hydraulic lifting may be slow due to low hydraulic fluid levels, air in the system, or a malfunctioning pump.

• Low hydraulic fluid levels can cause slow lifting as there is not enough pressure to operate efficiently.

• Air in the hydraulic system can create air pockets, leading to decreased performance.

• A malfunctioning pump can result in inadequate pressure being generated for lifting.

• Check hydraulic fluid levels and top up...read more

Engine systems can be categorized into internal combustion engines and external combustion engines.

• Internal combustion engines: gasoline engines, diesel engines

• External combustion engines: steam engines

• Other types: rotary engines, electric engines

Types of gear boxes include manual, automatic, CVT, DCT, and AMT.

• Manual gear box requires the driver to manually shift gears using a clutch pedal.

• Automatic gear box shifts gears automatically without the need for manual input.

• CVT (Continuously Variable Transmission) provides seamless gear shifts without distinct gear ratios.

• DCT (Dual Clutch Transmission) combines the efficiency of manual transmission with the convenien...read more

Main parts of an engine include cylinders, pistons, crankshaft, camshaft, valves, and spark plugs.

• Cylinders: where combustion takes place

• Pistons: move up and down in cylinders to create power

• Crankshaft: converts linear motion of pistons into rotational motion

• Camshaft: controls opening and closing of valves

• Valves: regulate flow of air and fuel into cylinders

• Spark plugs: ignite air-fuel mixture in cylinders

Possible reasons for tractor not taking load properly

• Check if the clutch is slipping

• Inspect the transmission for any issues

• Examine the hydraulic system for leaks or malfunctions

• Verify if the engine is producing enough power

• Assess the condition of the tires for proper traction

White smoke from a tractor can be caused by a few different reasons, such as coolant leaking into the combustion chamber or unburned fuel in the exhaust system.

• Possible reasons for white smoke from a tractor include coolant leaking into the combustion chamber, unburned fuel in the exhaust system, or a faulty fuel injector.

• Check the coolant level and quality to see if there are any signs of contamination.

• Inspect the exh...read more

Tractor emitting black smoke may be due to issues with fuel, air, or engine components.

• Possible reasons for black smoke include fuel injector issues, clogged air filter, or engine timing problems.

• Check fuel quality and injector system for proper functioning.

• Inspect air filter for blockages and replace if necessary.

• Ensure engine components such as valves and pistons are in good condition.

• Consult a mechanic for further d

Blue smoke in a tractor could be caused by burning oil due to worn piston rings or valve seals.

• Possible reasons for blue smoke in a tractor include worn piston rings or valve seals

• Burning oil can also be caused by a damaged cylinder head gasket

• Excessive blow-by from the crankcase ventilation system can lead to blue smoke

Hydraulic oil pressure is the force exerted by hydraulic oil within a hydraulic system.

• Hydraulic oil pressure is measured in pounds per square inch (psi).

• It is crucial for the proper functioning of hydraulic systems, as it determines the force and speed of hydraulic actuators.

• Low hydraulic oil pressure can result in sluggish performance, while high pressure can lead to system damage.

• Maintaining the correct hydraulic oi...read more

Free play of clutch refers to the distance the clutch pedal can be depressed before the clutch begins to engage.

• Free play is important for proper clutch operation and to prevent premature wear.

• It allows for smooth engagement and disengagement of the clutch.

• Adjusting the free play may be necessary to ensure proper clutch function.

• Excessive free play can indicate a problem with the clutch system.

Free play of brake refers to the amount of movement in the brake pedal or lever before the brakes start to engage.

• Free play is important for ensuring the brakes do not engage too early or too late.

• It can be adjusted to suit the rider's preferences or to compensate for wear in the brake system.

• Excessive free play can indicate a problem with the brake system that needs to be addressed.

• For example, on a motorcycle, adjust...read more
