IFPE 2005 - John Deere
More than 124,300 industry professionals from around the world attended the co-located IFPE 2005 and CONEXPO-CON/AGG 2005 trade expositions in Las Vegas, USA during the shows' five-day run March 15-19 at the Las Vegas Convention Center. The shows featured the latest equipment, product innovations and technological advances of the construction, construction materials and power transmission industries. In addition to breaking the all-time record attendance number and setting a new record for international attendance, IFPE 2005 was also the largest in the shows history in terms of exhibit space.
PowerTech Plus Engines
To accomplish this while meeting Tier 3/Stage III A challenges, we applied a number of proven technologies to the new engines, including cooled exhaust gas recirculation (EGR), a variable geometry turbocharger (VGT), high-pressure common rail fuel systems, and more. As a result, PowerTech Plus engines are the models of Tier 3/Stage III A efficiency and performance.
Cooled EGR is a highly effective method of reducing peak combustion temperature, which reduces the amount of oxides of nitrogen (NOx) in the exhaust and as a result helps the engine comply with Tier 3/Stage III A regulations. During certain conditions of engine operation, the EGR valve opens and measured amounts of cooled exhaust gas are routed back into the intake manifold and mixed with the incoming fresh air. Since this process removes some oxygen from the air, the exhaust temps are lowered and the NOx levels reduced.
The variable geometry turbocharger tailors the amount of cooled exhaust gas that mixes with the fresh air, thanks to an electronic control unit that changes the pitch of the VGT vanes. The control unit adjusts the vanes to correspond with any changes in engine load.
To offset the increase in particulate matter caused by the reduction of NOx, John Deere has taken the following steps in our PowerTech Plus engines:
Increased fuel injection pressure for more complete combustion
Adopted improved valve guide seals and new piston ring design to reduce oil consumption
Adopted VGT to control transient smoke
Improved the shape of the combustion bowl to maximize air/fuel mixing and burn all available fuel.
All this technology has combined to help us achieve the following goals for the PowerTech Plus engines:
Same or better power ratings for each level of displacement
Same or better peak torque levels
Same low-speed torque
Same or better fuel economy
Same or better transient response time
Same or better cold weather starting
For high-performance markets, count on John Deere PowerTech Plus engines to deliver efficient power while meeting Tier 3/Stage III A emission regulations.

Power Systems introduced the new PowerTech 2.4L and 3.0L engines as a more
cost-effective solution to power various equipment requiring 36 to 74 kW
(49 to 99 hp). With these new engines, John Deere achieves their
objective of making significant improvements in noise, vibration,
packaging, and cost, while ensuring that the 2.4L and 3.0L engines are
Tier 2/Stage II compliant with an eye toward Tier 3/Stage III A.

The 2-valve 4.5L and 6.8L engines
are equipped with electronic fuel systems, providing an array of standard
performance benefits: higher injection pressures, variable timing control,
precise control of fuel injection, improved cold weather starting, engine
isochronous or droop governor selection, and key start/stop. The 2-valve,
electronic 4.5L engine models provide power ranging from 82 to 104 kW (110
to 140 hp), while the 2-valve, electronic 6.8L engine models provide a
power range of 101 to 186 kW (135 to 250 hp).
In addition to the electronic model, the 4.5L, 2-valve is available with a mechanical rotary fuel injection system. Both turbocharged and naturally aspirated versions are offered. The mechanical 4.5L models range in power from 55 to 74 kW (74 to 99 hp).

Engineered with 4 valves per cylinder, the 16-valve 4.5L and 24-valve 6.8L
engines offer enhanced airflow, improved efficiency, and increased power
and torque. With an increase of up to 25 hp, these engines allow OEMs and
end-users to avoid buying engines in a larger displacement class, saving
them significant costs. Higher peak torque delivers power in the tough
spots, while the increase in low speed torque allows for improved load
starting.
The 4-valve 4.5L and 6.8L engines are both air-to-air cooled. Standard power ratings for the 4.5L are 119 kW (160 hp) and 129 kW (173 hp); for the 6.8L, power ratings are186 kW (250 hp) and 205 kW (275 hp).
