PRODUCT GUIDE
POWERTRAIN

Infinitely variable
transmission,
variable power divider
Marmon-Herrington's (Louisville, KY)
infinitely variable transmission (iVT) and
variable power divider (VPD) technologies are both part of the company's
HydroMech family of products for Class 6
through 8 trucks. The new HydroMechiVT
hydro-mechanical transmission maximizes the advantages of both hydrostatic
and mechanical transmission technologies, while its new HydroMechVPD eliminates the need for an auxiliary diesel engine in applications where a second power source has traditionally been required.

By combining the benefits of low-speed
hydrostatic drive and high-speed mechanical drive, Marmon-Herrington's iVT
is expected to provide fleets a reduction
in operating costs, maintenance, fuel consumption, and greenhouse gas (GHG)
emissions, as well as associated driver
benefits. By dividing the truck's diesel
engine into propulsion power and auxiliary power, the Marmon-Herrington VPD
is said to reduce operating costs, maintenance, and GHG emissions for fleet managers while providing driver-friendly benefits to equipment operators.

Corrosion resistance ranking
Federal-Mogul Powertrain's (Southfield,
MI) new process for ranking the corrosion resistance of diesel cylinder liner
materials will enable the company to
supply even more durable components
for the most challenging applications. By
enabling direct comparison of different
materials and coating processes, the
new test methodology allows material
development to be specifically targeted
at circumstances involving poor-quality

fuel and high levels of exhaust gas recirculation. According to the company, prior to this work there was no recognized
procedure for comparing the likely corrosion resistance of different materials
during engine operation; the complex
relationship between mechanical wear
and corrosion means that each must be
evaluated independently to identify the
most resistant materials. Federal-Mogul
Powertrain has accurately reproduced
the corrosive solutions of combustion
products formed inside an engine-including sulphuric, nitric and acetic acids-and used them to carry out a range
of tests. Results of this program will
guide future material selections for diesel engine manufacturers.

Oil change valve
Global Sales Group (Redmond, WA)
offers a new and improved EZ Oil Drain
Valve with optional hose connectors
that can replace an existing drain plug
for fast, clean and easy oil changes.
According to the company, there is no
need for special tools: just turn the lever
of this nickel-plated brass ball valve and
drain the engine oil. When it's time for

an oil change, the lever lifts and a quarter turn opens the valve. To close, the
lever is returned to its original locked
position. Screw in the optional hose end
(sold separately) and connect a hose to
drain the oil to a remote receptacle. For
routine oil analysis, a small sample of oil
can be drained from the valve without
shutting off the engine. The EZ Oil Drain
Valve is available for all engines with 30
different sizes to fit cars, pickup trucks,
vans, farm tractors, motor homes,
heavy-duty trucks, buses, and construction equipment.

Fan drive systems
Multi-Wing America (Burton, OH) is a
single-source provider for fan and fan
clutch systems. The viscous clutches are
either electronically-controlled or airsensing via bi-metal sensor. These fandrive systems are suitable for off-highway and stationary equipment, including
agricultural tractors, skid steers, excavators, construction equipment,
pavers, articulated dump
trucks and power generators.
Available for
small- to largequantity orders,
these products help meet stringent
emissions requirements, provide fuel
savings and significantly reduce noise.
The fan clutches have a broad modulation range, low off-speed and flexible
mounting options. This line of products
reduces cooler clogging and is maintenance-free with a long operating life.
Paired with an innovative customized
Multi-Wing fan, the electronically controlled fan clutches are available in a
wide torque range, respond quickly with
precise modulation and are suitable for
low-temperature operating conditions.
Lightweight and durable, the bi-metal
fan clutches have high temperature sensitivity and a fast response time.
