Borg Warner To Supply
VTG Turbos To Deere
John Deere has selected Borg Warner to supply its
variable turbine geometry (VTG) turbochargers to
boost John Deere Power Systems Tier 4 interim/Stage
3b Power Tech PVX and Power Tech PSX 4. 5 L, 6. 8 L
and 13. 5 L diesel engines. VTG turbochargers control
EGR flow by precisely opening and closing guide
vanes to balance the exhaust pressure to intake pressure. Beginning with Tier 4 interim engines, Borg-Warner VTG turbochargers will feature a compact brushless actuator specifically designed for
heavy-duty turbochargers and EGR valves.
Horton Adds To Modular Fan Line
Horton has launched the Shogun modular
fan, available in a variety of blade counts and
configurations for first-fit applications. It is
compatible with Horton and competitive viscous fan drives, said the company. Available
fan diameters range from 406.4 to 559 mm in
configurations of six to 10 equally spaced
blades (staggered configurations are available by request) with clockwise or counterclockwise rotations. The fans can provide airflow up to 6.607 m3 and were designed to
meet the cooling requirements of reduced-emissions engines on buses, motorhomes
and off-highway equipment.

DEF Gauges
Ametek Vehicular Instruments Systems
(VIS) has introduced its C-COM and Next
Generation Instrumentation (NGI) dashboard
displays. Ametek’s CAN-Communicator (
C-COM) 2G displays the diesel exhaust fluid
(DEF) level from the SAE J1939 data bus in a
graphical chart format. In addition, Ametek
offers a module compatible with its NGI dashboard instrumentation system 2-in- 1 gauge
that combines both fuel level data in a standard needle gauge and DEF level in a four-segment bar graph.

Air-Fuel Ratio Controllers
Altronic Inc. has announced its EPC 50 air-fuel ratio controllers for low-horsepower, carbureted natural gas-fueled
engines. An oxygen sensor in the exhaust stream senses O2
content, and a thermocouple input signals when proper
exhaust temperature has been reached. The EPC 50 also incorporates a thermocouple input and a dedicated output for
implementation of catalyst over-temperature protection. The
EPC 50 has an alphanumeric LCD display, and the power
requirement is 24 ( 12 to 30) Vdc, 1 Amp.
