leaving a warm house, getting into a cold or freezing vehicle that
is difficult to start, and making your way on wet or icy roads - peering
through misted-up windows and with only cold air to provide little
help and no comfort. Most car owners experience the additional difficulty
of negotiating busy junctions during rush hour with the engine either
racing on a rich mixture or ready to stall! Perhaps you start to see
and feel an improvement just as you pull into work, complete the school
run or arrive at the shops - and throughout fuel consumption is excessive.
starting your engine easily, without choke and feeling instant warmth
from the heater - imagine too the luxury of a warm and comfortable
interior throughout even the shortest journey, with clear vision
from instant hot air demisting and travelling on wet or icy roads
WITHOUT the engine racing away. (Perhaps a child crosses the road
on his way to school necessitating an emergency stop!) The KENLOWE
Hotstart brings you all this AND improves your fuel consumption
by up to 46% on short journeys whilst minimising engine wear caused
by running whilst cold. (Battery, starter motor and exhaust life
are also significantly improved.) KENLOWE Hotstart also ensures
easier starting on petrol and diesel engines, significantly increases
the efficiency and life of catalytic converters and reduces pollution!
Only hot air can de-ice windows, and keep them free from misting-up
- all round clear vision is not just common sense it is a legal
requirement. Peering through a small patch that you can reach to
keep free of moisture limits peripheral vision to a dangerous degree
- in addition warm breath turns into moisture on a cold screen when
the glass is below the dew point temperature of the breath from
the driver and passengers. Frosted or iced over windows due to the
vehicle being left out in the open, can now be de-frosted or de-iced
without resorting to the chilling job of scraping the windows or
using expensive chemicals, neither of which avoid the glass misting
up as soon as you are inside the vehicle.
Cold engines need a rich mixture to start and run whether carburettor
or fuel injected. The graph shows up to 46% of fuel is wasted during
the first few miles from cold and not even the most modern engine
becomes fuel efficient until the engine block has reached full working
temperature. The KENLOWE Hotstart ensures the block as well the
coolant is at running temperature before you set off, making poor
fuel consumption on short journeys a thing of the past - even on
a journey as long as 9 miles you can save 12% of your fuel. Of course,
being at full running temperature before you start means you arrive
at the end of even a short journey with more heatsoak in the engine
block than would occur without pre-heating and some residual heat
is stored for long periods in the engine block which minimises any
tendency for choke to be needed when restarting later in the day.
Eight hours of daytime winter ambient temperatures are much milder
than a sixteen hour overnight period when the engine is not run!
High fuel costs or vehicles with high fuel consumption, such as
4x4 off-road vehicles used for everyday use, turns the percentage
of fuel saved into a significant annual sum. What % saving would
you make on your journey? Graph shows fuel wasted when starting
from cold. Remember the Kenlowe engine pre-heater avoids need for
choke or enrichment if the engine in fuel injected.
COLD RUNNING DAMAGES THE ENVIRONMENT!
During the first period from a cold start up to 100% more fuel is
used - all this extra fuel passes through the engine unburned but
heated into a gas before passing into the atmosphere as ozone damaging
hydrocarbons. KENLOWE Hotstart pre-heats your engine before you
start, which eliminates the damaging eflect of these gases on the
CONVERTERS DO NOT WORK WHEN COLD!
The Daily Telegraph reported that "catalytic converters which are
made from expensive platinum and rhodium do not remove the hydrocarbons
which damage the atmosphere when the engine is started and run cold!"
They also reported that "one quarter of all travel is carried out
with a cold engine!" In addition some catalytic converters actually
incur a fuel penalty and cause more pollution when the engine is
cold than cars not fitted with a catalytic converter!
Cold running of your engine requires enrichment whether fuel injected
or carburettor. Enrichment results in unburnt fuel leaving the cylinder
which becomes trapped in the catalytic converter where it causes
significant damage. Owners who do frequent short runs (e.g. to work,
shops or school run) can damage the catalytic converter within as
little as 18 months!
Starting with a cold engine accounts for up to 80% of engine wear
owing to unburnt fuel droplets washing oil from the cylinder walls.
The life of auxiliaries, such as starter motor, exhaust, and battery,
are all significantly extended by starting a HOT engine easily.
Using the Kenlowe engine pre-heater means the starter motor is not
called on to crank the engine over and over even on the coldest
day, in addition condensation in the exhaust system is significantly
reduced. Large fleet operators running their vehicles 24 hours a
day (3 shifts) have found for many years that avoiding cold starts
extends the engine life to a minimum of 1,000,000 miles and often
as much as 1,500,000 miles with only routine servicing, fully illustrating
how much harm is done to your engine by starting and running cold.
With the M.O.T.
test requiring replacement at anything from £350 to £1,000 cold
starting can prove costly!
A cold engine can be difficult to start, whether it is diesel or
petrol, because the battery voltage drops as the weather gets colder
and to compound this little or no charge can be put back during
short winter days when lights and interior heater are in constant
use. (A particular problem on vehicles limited to short journeys.)
Cold winter nights also result in the engine oil becoming thicker
- in North America or Scandinavia thick oil alone can cause enough
viscosity to stop the engine being turned over! A KENLOWE Hotstart
assures you of starting every time however cold the weather.
STARTING AND LONGER ENGINE LIFE
Diesel engines rely entirely on the heat generated by the compression
stroke to give the required temperature to obtain spontaneous combustion
of the air/fuel mixture in the cylinders. Normally with a low mileage
engine and ambient air temperatures of +1000, and above, a gas temperature
in the cylinder of 50000, or more is achieved during the initial
compression stroke which is sufficient to give spontaneous ignition
and the engine starts. On higher mileage engines or when air temperatures
fall below +1000 (and on many mornings throughout the year they
do), the ability of a diesel engine to start is greatly impaired!
The cylinder walls, pistons and surrounding metal absorb the heat
generated by the compression stroke and the required minimum temperature
for ignition of 37500, becomes more difficult to reach. At temperatures
of zero or below starting can become almost impossible without some
form of assistance, especially if the engine is not new. With older
engines the first sign of wear is a reluctance to start on cold
mornings and the slightest loss of compression means insufficient
heat for combustion. Even with the help of various aids engine start
may not be achieved! The most logical and simple solution to this
problem is heat, increase the block temperature and cold weather
starting difficulties disappear. An engine at running temperature
before you start will minimise the tendency for fuel to wax in the
fuel filter, injectors or fuel lines. The KENLOWE Hotstart can extend
the useful working life of an engine by many years, saving the cost
of a new! reconditioned engine which, along with lost revenue during
expensive downtime, can amount to a considerable sum.
in the coldest weather (-9ÉC or colder) requires special low temperature
fuels to prevent waxing in the tank.
