Land Based L2 Engineering Quiz

Engine power and torque are measured in?

• KW and Nm

• BP and KW

• KW and CC

• CC and Nm

Answer explanation

Engine power is measured in kilowatts (KW) and torque is measured in Newton-meters (Nm), making KW and Nm the correct units for engine power and torque measurements.

An engine with one cylinder has a power stroke for every other revolution of the crankshaft, this cycle of operation is:

• Two Stroke

• Three Stroke

Which component stores the energy produced?

• Flywheel

• Piston

• Connecting Rod

• Crankshaft

The engine component used to control the crankshaft end float is known as a:

• Shell bearing

• Thrust washer

• Chain tensioner

• Coil spring

An engine induction system is not fitted with a pressure charger, it is referred to as being:

• A four-stroke engine

Four stroke, four cylinder in-line engine has a firing order of 1,3,4,2. If cylinder number 3 is on the induction stroke.

• 2 will be on the compression stroke

• 2 will be on the exhaust stroke

• 4 will be on the power stroke

• 2 will be on the power stroke
