KAWASAKI
A brand of motorcycle produced in Japan.
KE-JETRONIC
A mechanical hydraulic injection system provides the basis for
the KE-Jetronic. This basic system is supplemented by an electronic
control unit (ECU) in order to increase flexibility and to enable
further functions.
K-JETRONIC
The K-Jetronic is a mechanically and hydraulically controlled fuel-injection
system which needs no form of drive and which meters the fuel as
a function of the intake air quantity and injects it continuously
onto the engine intake valves.
KNOCK CONTROL
The Mono-MOtronic can also be equipped with knock-control. This
utilises the signal from the knock sensor on the engine block to
adjust the ignition advacne angle in order ro take full advantage
of the avaible fuel quality. The result is a reduction in fuel
consumption while at the same time ensuring that the engine cannot
be damaged by combustion knock.
KNOCK
INHIBITORS
The most effective knock inhibitors are organic lead compounds.
These can raise the octane number by several points, with the exact
amount depending on the specific hydrocarbon structure. Both DIN
51600 and most European national standards limit lead content to
maximum of 150 mg per litre of fuel. Environmental considerations
have combined with increasingly widspread use of catalytic converters
to produce a steady reduction in the use of lead alklys.
KNOCK LIMIT
OPeration with a catalytic converter requires that the engine be
operated with unleaded gasoline with an excess-air factor of lambda=1.0.
Previously, lead was mixed into gasoline as an antiknock freeoperation
at high compression ratios E.With unleaded gasoline, a
low compression ratio and higher fuel consumption can be expected
KNOCK
PROTECTION
The octane rating defines resistance to preignition engines. Higher
octane ratings indicate a greater resistance to knock. Two different
procedures are in international use for defining octane ratings.
KNOCK
SENSOR
Sensor which, fixed to the crankcase, can detect the so-called
knocking.
KNOCKING
Metallic noise produced by a faulty combustion cycle inside the
cylinder also known as pinging.
KNOCKING TENDENCY
One further inportant interrelationships is that between ignition
point ant the engine's tendency to knock. This is demostrated by
the effect of a too early or too late ignition point on the pressure
in the combustion chamber. If the ignition point is too early,
mixture a t various points in the combustion chamber also ignites
owing to the ignition pressure wave. This means that the mixture
burns irregularly and intense pressure wave. This means that the
mixture burns irregularly and intense pressure fluctuatuions occur
with high combustion-pressure peaks. This effect, called kncoking,
cnabe heard clearly at low engine speeds. At high engine speeds,
the noise is smothered by the engine noise. But it is precisely
in this range that knocking may lead to engine damage and it must
thus be avoided by finding an optimum combination of suitable fuel
and ignition point.
KNUCKLEHEAD
The name of the Harley-Davidson engine used from 1936-1947. If
you sit on the seat of a knucklehead machine and look down
to the right side of the engine, the rocker box looks like
the knuckles on your fist.
KW
The kw refers to a multiple of the watt (w) i.e. the unit of
measure of power.
