Dear William,

Above image is an actual photo of diesel engine fuel
combustion.
Welcome to Enertech Labs Newsletter Number 9.
This month we will discuss changes in gasoline's and the problems
associated with those changes, the truth about Winter Blended
Diesel Fuels, and Fluid Maintenance in vehicles and equipment.
As you read through this newsletter you can finish reading each

Due to the large number of recent changes to fuel, numerous
problems with gasoline powered vehicles have developed. These
problems are not always immediately identified as fuel
problems, and therefore technicians are spending a lot of time
and money on symptoms, rather than root causes. Most
technicians will tell you that they have seen a dramatic
increase in the number of complaints of performance, poor fuel
economy, or Check Engine light illumination due to the failure
of the exhaust related emissions items (EGR, Oxygen Sensors,
Catalytic Converters, etc.) in the last 2 years. Ask them the
root cause and you will hear many theories.
In order to properly understand what is happening a little
history review is helpful. In the late 1980?s emissions
standards had become more stringent making fuel injection a
necessity. These vehicles burned cleaner and ran better than
Carburetor equipped vehicles ever could. Drive-ability
concerns ...

#2 Diesel Fuel contains a significant amount of paraffin wax. On
the positive side this wax contains a lot of energy (Btu?s) and
adds viscosity and lubricity to diesel fuels. The downside of
paraffin wax is that it causes cold weather problems for users. As
the fuel gets colder the wax crystals grow in size until they
become visible (cloud point (CP)), next they begin to interfere
with each other and inhibit the movement of the fuel (cold filter
plug point (CFPP)), and finally they grow together turning into a
semi- solid (pour point (PP)).
#1 Diesel, Kerosene, and Jet Fuel are lighter versions of regular
diesel, having a different boiling point and much less paraffin
wax. There is a lot of misunderstanding about Winter Blended
Diesel Fuel, what it is, and what it can do. You can improve the
cold weather characteristics of diesel fuel ...

Fluid and fluid maintenance are one of the most important areas of
vehicle and equipment maintenance.
The need for engine oil service is fairly well known and
recognized. Oil additives that help oil perform and protect, tend
to break down or get used up over time and no longer perform their
functions. Additives include detergents to keep engines clean and
friction modifiers to prevent wear. Oil also becomes contaminated
with by products of combustion which pass by piston rings and
moisture from the air which mixes with oil to form various acids.
All these can lead to wear and sludge. Oil flush and oil additives
can remove sludge, and extend oil life. Dirty oil can easily be
observed and shown to a customer.
Transmission Fluid has four main functions ...

The Wartsila-Sulzer RTA96-C turbocharged two- stroke diesel engine
is the most powerful and most efficient prime-mover in the world
today.
It is available in 6 through 14 cylinder versions, all are inline
engines. These engines were designed primarily for very large
container ships. Ship owners like a single engine/single propeller
design and the new generation of larger container ships needed a
bigger engine to propel them.
The cylinder bore is just under 38" and the stroke is just over
98". Each cylinder displaces 111,143 cubic inches (1820 liters)
and produces 7780 horsepower.
Total displacement comes out to 1,556,002 cubic inches (25,480
liters) for the fourteen cylinder version.
Some facts on the 14 cylinder version: Total engine weight: 2300
tons (The crankshaft alone weighs 300 tons.) Length: 89 feet
Height: 44 feet Maximum power: 108,920 hp at 102 rpm Maximum
torque: 5,608,312 lb/ft at 102 rpm
Fuel consumption at maximum power is 0.278 lbs per hp per hour
(Brake Specific Fuel Consumption). Fuel consumption at maximum
economy is 0.260 lbs/hp/hour. At maximum economy the engine
exceeds 50% thermal efficiency. That is, more than 50% of the
energy in the fuel in converted to motion.
For comparison, most automotive and small aircraft engines have
BSFC figures in the 0.40-0.60 lbs/hp/hr range and 25-30% thermal
efficiency range.
Even at its most efficient power setting, the big 14 consumes
1,660 gallons of heavy fuel oil per hour.
