An Answer Today to the Challenges of the Cities of Tomorrow!

TMCleanStart

Public transport is essential to the economic competitiveness of a large city but also to its cultural, economic and commercial exchanges.

Urban centres are also faced with the problem of increasing traffic, the rise in noise nuisance and pollution.

Cities are often caught between the attractiveness of urban centres, the growing need for transport, the rising cost of fuel, polluting emission reductions and optimising regional and municipal budgets...

Poclain Hydraulics proposes “Stop & Start” – a solution well known in the automotive industry, simple, reliable, quick to implement and adaptable to any type of bus.

Reconciling urban development with clean transport policy:Poclain Hydraulics, a company committed to improving the lives of local residents.

The CleanStart solutionTM

IMAGINE

…You are in the heart of the city and its hustle and bustle. You are waiting for a bus so you can get to your meeting. A bus approaches and the noise of its engine clearly emerges from the flow of traffic. It stops

in front of you and instantly the noise stops when its engine turns off. You hear only the opening of its doors and laughter from a small group of people seated on the terrace of a café nearby. They savour this moment

without being inconvenienced by the exhaust gas. You board the bus. There is no vibration, passengers are conversing easily without straining their voices. Outside, passers-by are surprised by this silent and

stationary bus; nothing seems to be disturbing them anymore.

IMAGINE ...The driver exchanges a few words with a passenger while giving him his travel ticket.

Surprised by the engine being completely turned off, you take a seat and enjoy the quietness which fills this bus.

The doors close. With a glance towards the flow of traffic, the driver restarts the bus by simply pressing on the accelerator pedal, without jerking.

In a fraction of a second the engine starts to hum slowly. The bus resumes its route.You will be relaxed and on time for your meeting.

You congratulate yourself for living in a city which does all it can to improve the quality for life of its residents.

IMAGINE

You are not dreaming, this is

CleanStart by Poclain Hydraulics.TM

CleanStart : a hydraulic “Stop & Start” system enabling the engine to turn off when the bus is not moving (passengers getting on/off, traffic jams) and the instantaneous restarting of the engine (less than 0.5 seconds) as soon as the driver wants to resume his route.

A technology immediately available to your bus fleet.

Already adopted by a major manufacturer of handling equipment (MANITOU), CleanStart

is today in series production on all the latest telescopic forklift truck models.

An expert in drive solutions for over 30 years, Poclain Hydraulics is offering the urban transport sector an “original equipment” solution or one that can be adapted and retrofitted to existing bus fleets.

Installation is completed within a few hours without interruption to service.

CleanStartTM is compatible with all fuel types (NGV, diesel or green fuels) without prior modification. Furthermore, CleanStartTM will not restrict your future engine power choices.

CleanStartTM is not a substitute for the original starter; this latter remains fully operational in case of need.You are therefore putting into circulation a bus equipped with a system designed to deal with more than 2.5 million start-ups.

100% recyclable, CleanStartTM is fully neutral in terms of its environmental footprint.

Perfectly transparent in maintenance programmes, it does not require any special skill or installation for its routine maintenance.

CleanStartTM generates savings from its first day of use and ensures profitability without any particular subsidy.

In 2014, the major transportation authority of Paris has rewarded CleanStart

for its simplicity of installation as well as its results in terms of reducing CO2 emissions, saving fuel and providing comfort for both driver and passengers.

Typical case: fleet of 100 buses, active 10 hours/day, 300 days/year. Fuel consumption: 60 l/100 km and 2.3 l/hour at idle speed.

*Which is an 8% fuel saving that is to say 210,000 liters per year.

For 100 buses fitted with CleanStart :

Silent 30 % of the time

> 500 T less CO2 is released

$ 260,000 / year is saved in diesel*

CleanStart system in details.

CleanStart™ consists of a hydraulic starter (1), which directly drives the engine crankshaft. Its function is to provide instant torque higher than the resisting torque of the engine (inertia and compression ratio), that is a maximum torque of 550 Nm. The compactness of this starter allows for an original positioning, directly into the engine pulley. The power density of the hydraulic starter enables greater responsiveness and a start-up in less than 0.5 seconds, while reducing energy losses.The hydraulic pump (2) pressurises the accumulator in preparation for the next engine start-up. A sequence valve (3) directs the pump flow for the time required to pressurise the accumulator. The stored energy (volume of oil under pressure) is sufficient to power the hydraulic starter for at least one start-up sequence.

The hydraulic accumulator (4) stores the hydraulic energy necessary for starting up the engine. Since the batteries are not needed at every start-up, their life span is conserved. Fully recyclable, it furthermore presents a weight/power ratio that is very favourable when compared with batteries.The tank (5), which holds the oil.The electronic control unit (6) ensures the accumulator filling and draining sequences, provides system status updates and sends diagnostics.
