Spinny Evaluator Interview Questions and Answers

A 4-stroke engine is an internal combustion engine that completes four separate strokes in the intake, compression, power, and exhaust processes.

• Intake stroke: Fuel and air are drawn into the combustion chamber.

• Compression stroke: The fuel-air mixture is compressed by the piston.

• Power stroke: The spark plug ignites the compressed mixture, causing an explosion that drives the piston down.

• Exhaust stroke: The piston ...read more

To identify a misfired car, look for symptoms such as rough idling, decreased engine power, and unusual exhaust emissions.

• Listen for a rough or uneven engine idle.

• Notice a decrease in engine power or acceleration.

• Observe unusual exhaust emissions, such as black smoke or a strong smell of fuel.

• Check for a flashing check engine light on the dashboard.

• Perform a diagnostic scan using an OBD-II scanner to retrieve erro...read more

The connecting rod is a component in an engine that connects the piston to the crankshaft.

• The connecting rod is located inside the engine block.

• It connects the piston to the crankshaft, transferring the linear motion of the piston into rotational motion of the crankshaft.

• In a typical four-stroke internal combustion engine, each cylinder has a connecting rod.

• The connecting rod is usually made of steel or aluminum a...read more

Gear box overhaul can be identified through various signs and symptoms.

• Unusual noises or vibrations coming from the gear box

• Difficulty in shifting gears or gears slipping

• Leaking fluid or visible damage to the gear box

• Decreased performance or power

• Increased fuel consumption

• Warning lights or error codes related to the gear box

• Excessive heat or burning smell from the gear box

The plug is typically attached to an electrical outlet.

• The plug is usually connected to a wall socket or power strip.

• In some cases, the plug may be attached to a power cord or extension cord.

• The plug can be found in various locations depending on the specific device or appliance.

• Examples include plugs on the back of a computer tower, the side of a television, or the bottom of a lamp.

To check the tyre year and manufacturing, look for the DOT code on the sidewall of the tyre.

• The DOT code is a combination of numbers and letters usually located on the sidewall of the tyre.

• The last four digits of the DOT code indicate the week and year of manufacture.

• For example, if the last four digits are '2318', it means the tyre was manufactured in the 23rd week of 2018.

A turbocharger boosts engine power by using exhaust gases to spin a turbine, compressing intake air for better combustion.

• Turbochargers consist of two main components: a turbine and a compressor.

• The turbine is driven by exhaust gases, which spin it at high speeds.

• As the turbine spins, it drives the compressor, which draws in and compresses air.

• Compressed air increases the amount of oxygen available for combustion,...read more

Salary depends on various factors like experience, role, and industry standards.

• Experience Level: More experienced professionals typically earn higher salaries.

• Industry Standards: Salaries can vary significantly between industries; tech jobs often pay more than education.

• Location: Salaries may differ based on geographical location; urban areas usually offer higher pay.
