When you dig a little deeper into the numbers, Clifton says, you can see the importance of measuring fuel efficiency rather than simply raw gallons-per-hour fuel consumption.

0000009729 00000 n There’s efficiency in having an engine run at constant speed, of course, but the low-speed-matching system in the hybrid improves on that benefit.”If you stand next to the HB215LC-1 when it’s working, you hear the engine varying its speed.

In addition, the hybrid showed a significant advantage in working speed, which could translate into added production.For the truck-loading evaluation, Peters used each machine to 10-pass load a tandem-axle dump truck multiple times. 0000004023 00000 n

They offer equivalent performance (ie same breakout forces and operating speed) to the conventional

Under a normal workload the excavator should use approximately 12 gallons per hour. 0000007252 00000 n

0000035017 00000 n According to Nájera, some customers have used the hybrid in noise-sensitive areas where its constant-speed counterpart would have been noticeably louder.“But the different sound of the engine can work against the hybrid,” he says, “because some operators, if they don’t hear the engine lugging down, conclude that the machine lacks power.

First, as Nájera explains the system, the hybrid’s engine idles at 700 rpm, significantly below that of the PC200LC-8’s engine and another plus for fuel conservation.

P mode – Power or work priority mode has low fuel consumption, but fast equipment speed and maximum power. 0000004829 00000 n All Rights Reserved.Testing Reveals Komatsu Hybrid’s Fuel-Sipping CharacterPlease describe any special features or additional needs for your excavator, such as specific performance criteria, attachments, etc.Let's finish up! • Low fuel consumption by total control of the engine, hydraulic and electronic system.

Although rated horsepower is close, the smaller engine is significantly more fuel-efficient, says Komatsu.Controlling the overall functioning of the hybrid system is electronic intelligence that makes decisions about how the system’s electrical power is best used in the machine’s activities—whether the generator motor assists the engine or charges the capacitor, and whether the capacitor sends power to the swing motor or to the generator motor to assist engine acceleration.Komatsu has taken engine efficiency in the HB215LC-1 a step further with its “low-speed-matching” system. 0000002065 00000 n
