Wilo Mather and Platt Pumps Senior Application Engineering Executive Interview Questions and Answers

An engine is a machine that converts energy into mechanical work, commonly used in vehicles and machinery.

• Types of engines include internal combustion engines (e.g., gasoline engines) and electric engines.

• Internal combustion engines operate by burning fuel to create power, as seen in cars and motorcycles.

• Electric engines use electrical energy to produce motion, commonly found in electric vehicles and appliances.

• Engines...read more

A hydraulic system uses fluid power to perform work, utilizing incompressible fluids to transmit force and motion.

• Hydraulic systems operate on Pascal's principle, where pressure applied to a confined fluid is transmitted equally in all directions.

• Common applications include hydraulic brakes in vehicles, hydraulic lifts, and construction equipment like excavators.

• Hydraulic fluid is typically oil, which provides lubricat...read more

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

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

A hydraulic component is a device that utilizes fluid power to perform mechanical tasks.

• Hydraulic components use liquid to transmit power.

• Common examples include hydraulic cylinders, pumps, motors, valves, and hoses.

• They are often used in heavy machinery, construction equipment, and industrial applications.

Realy is a type of relay used in electrical systems to control high power devices with low power signals.

• Relays are switches that open and close circuits electromechanically

• Realy is a type of relay specifically designed for high power applications

• Working principle involves an electromagnet that moves an armature to open or close the circuit

• Commonly used in industrial automation, automotive, and HVAC systems

Least count is the smallest change in the measured quantity that can be detected by the measuring instrument.

• Least count is determined by the smallest division on the scale of the measuring instrument.

• It is important for accurate measurements and precision in engineering.

• For example, a ruler with millimeter divisions has a least count of 1 mm.

• A vernier caliper with 0.1 mm divisions has a least count of 0.1 mm.
