Although lowering
engine speed normally means lowered output, this new system is able to generate higher output as the engine's piston stroke is approximately 20 percent extended from the conventional system.
Working with this system is a "one touch" idle control feature, which reduces
engine speed to low idle with the touch of a button; a second touch or joystick movement puts the engine back into high speed, allowing the machine to go right back to work.
The objective of the study is to analyze how well the currently working tractor is adapted to the provided work and optimal
engine speed as well as what load and fuel consumption are chosen during the operational work of the tractor.
IT sounds too good to be true; sizzling performance, strong throttle response at almost any
engine speed and reduced fuel consumption.
Operators, remember to reduce the dozer's
engine speed every time you shift in and out of reverse.
The operator chooses either field or transport mode, and the APM system reduces
engine speed whenever the implement load allows, automatically reducing fuel consumption and leaving the operator to concentrate on the work in progress instead of having to manually shift gears at just the right time and adjust the engine rpm with the throttle.
The drive unit powers the supercharger's low-inertia compressor independent of
engine speed, and can accelerate it from its idle speed of 5,000 rpm to 70,000 rpm in less than 0.
Fuel injection system must be able to meter the desired amount of fuel, depending on
engine speed and load, and to inject that fuel at the correct time and with the desired rate.
5-litre V6 engine power has risen to 313bhp at 6,800rpm and torque is now rated at 358Nm at 4,800rpm, while the maximum
engine speed has increased by 500rpm to 7,500rpm.
The belt-driven supercharger operates at low
engine speeds, with the exhaust-driven turbocharger coming in as the
engine speed increases.
It automatically accelerates the feed system when the engine load is light, slows when the load is high and reverses
engine speed drops.
Costing pounds 760 the performance pack boosts power from about 130bhp to around 155bhp at the same
engine speed.
