Concept l.jpg
CONCEPT

Series / Parallel system allows engine only, motor only

or engine-motor combination operation

During “motor only” operation diesel engine is at idle with clutch depressed.

Engine powers the ancillary systems & motor is used to move truck.

Engine does not shut off when stopped as hybrid autos do.


Concept6 l.jpg
CONCEPT

During deceleration, the clutch disengages the engine & the motor becomes a

Generator. The inertia of the moving truck is turned into electrons and is stored

in the battery. “Plug-In” option is available.

Gear selector l.jpg
GEAR SELECTOR

Gear displays are located in the dash of the vehicle and are supplied by Freightliner.

“Check Hybrid” and “Stop Hybrid” warning lights are also supplied by Freightliner and notify the driver of problems with the Hybrid system.

The Push Button Shift Control unit is supplied by Eaton and is available in two different configurations: City Delivery and Utility (pictured).

Braking l.jpg
BRAKING

During braking, the trucks momentum drives the pump/motor as a pump, transferring hydraulic fluid from the low-pressure reservoir to the high-pressure accumulator.


Pressurazition l.jpg
PRESSURAZITION

The hydraulic fluid compresses nitrogen gas in the accumulator and pressurizes the system to a maximum pressure of 5,000 PSI. The regenerative braking captures about 70% of the KINETIC energy produced during braking & turns it into POTENTIAL energy.


Reduced brake wear l.jpg
REDUCED BRAKE WEAR

Capturing 70% of the braking energy with the hydraulic fluid can reduce brake wear by more than 50%. The HLA system prevents service brake application till just before a complete stop.

Heavy refuse trucks may need 2 or more brake jobs per year. This system could stretch the life of one brake job to well over 1 year.

An average brake job may cost $3500.00 x twice per year X 8 years service life = $56,000.00

One brake job every year x 8 years service life = $28,000.00

$28,000.00 savings through reduced brake wear over 8 years


Launch assist l.jpg
LAUNCH ASSIST

During acceleration, fluid in the high-pressure accumulator is metered out to drive the pump/motor as a motor. The system propels the vehicle by transmitting torque to the driveshaft.

2 LAUNCH MODES AVAILABLE


Economy mode l.jpg
ECONOMY MODE

When the Hydraulic Launch Assist System is operating in Economy Mode, the energy stored in the accumulator during braking is used alone to initially accelerate the vehicle. Once the accumulator has emptied, the engine will begin to perform the acceleration. This process results in increased fuel economy.

Economy Mode Savings

Increased fuel economy of 30%

Increased acceleration of 2%

Economy mode allows for maximum fuel savings &

Maximum exhaust emission reductions of 20% to 30%


Performance mode l.jpg
PERFORMANCE MODE

In Performance Mode, acceleration is created by both the energy stored in the accumulator and the engine. Once the accumulator has emptied, the engine is completely responsible for acceleration. While fuel economy improvements are seen in Performance Mode, the greatest benefit is increased productivity

Performance Mode Savings

Increased fuel economy of 17%

Increased acceleration of 26%

Performance mode allows for faster cycle times,

More stops per day, & greater productivity
