How much oxygen does air have?
23.2% by weight
For complete combustion of gasoline, how much air is needed?
12.5kg/kg of fuel
The bore of an engine is 8cm and the stroke is 11cm. Find the piston displacement.
789.30cm^3
A prony brake test of a 4-stroke cycle 7.5cm x 10cm engine was conducted. The lever arm was 75cm at a net force of 60N and a speed of 1000rpm. Determine the BHP of the engine.
6.3
It is a special shaft that extends to the rear of the tractor and is designed to provide power to integral mounted or trailing implements such as mowers, balers, and rotavators.
PTO
It is a mixture of butane and propane and may be used to a considerable extent as engine fuel.
LPG
It is an instrument used for testing specific gravity of a liquid.
hydrometer
It is a special arrangement of gears so constructed and located in the transmission system of an automotive machine that will permit one driving member to rotate slower or faster than the other and at the same time propel its share of load.
differential
It refers to the driving force developed by a wheel or any other traction device.
traction
It is an engine part whose primary function is to maintain uniform engine speed by absorbing some energy during the power strokes and providing power during the idle strokes.
flywheel
It is the theoretical maximum percentage of kinetic energy of air which a wind rotor can convert into mechanical energy.
59.3%
The clutch is normally in this position.
engaged
In a spark ignition engine, fresh supply of air and fuel mixture enters the cylinder as the piston moves downward and the intake valve opens during this event.
intake
In order to properly stop the forward motion of the 4W tractor, the operator has to step on the:
brake and clutch pedals
The compression ignition engine is also known as:
diesel engine
