Chap 2 Flashcards
is a device that produces
power by burning normally liquid fuel inside the combustion
chamber of an engine.
INTERNAL COMBUSTION ENGINE
- Uses spark to ignite the fuel.
- Uses gasoline as fuel.
- Has a carburetor to mix fuel and air.
Spark-Ignition Engine
- Uses high compression to raise the
temperature of the air in a chamber and
ignites the injected fuel without a spark. - Uses diesel as fuel.
- Uses an atomizer to spray the fuel inside
the combustion chamber of the engine.
Compression-Ignition Engine
- Produces power in one revolution of the
crankshaft. - Fuel and oil is mixed in the combustion
chamber. - Usually high in speed and light in weight.
Two-Stroke-Cycle Engine
- Produces power in two revolutions of the
crankshaft. - Fuel is burned inside the combustion
chamber. - Relatively low in speed and heavy in
weight.
Four-Stroke-Cycle Engine
- One piston
- Appropriate for small engines
commonly used in the farm,
Single-Cylinder Engine
- More than one piston (2, 3, 4, 6, 8,
12) - Appropriate for high-powered
engines for driving tractors and
self-propelled equipment.
Multiple-Cylinder Engine

ENGINE PERFORMANCE CURVE
is an engineering vehicle specifically designed to deliver a
high tractive effort (or torque) at slow speeds for the purpose of
hauling a trailer or a machinery used in agriculture.
TRACTOR
A four-wheel
tractor of less than 20hp. It is used
for landscaping and gardening
rather than for massive agricultural
tasks. It is equipped with single
12in. moldboard plow and is
capable to plow 1 hectare within 11
to 14 hours.
COMPACT TRACTOR
A four-wheel
tractor with no less than 20
brake horsepower. It is used
for massive agricultural tasks
such as plowing, harrowing,
seeding and planting, and
other operations.
