|The Gates Electro-Mechanical Drive (EMD) stop/start system.|
Gates Corporation, a provider of belts, hoses hydraulics and related products for the auto industry, has introduced the first systems in its new Energy Saving product line targeted at both heavy-duty and light-duty vehicles.
The new line includes a stop/start system, a two-speed drive system for passenger subsystems, and an idle-reduction system for heavy-duty trucks.
The Gates Electro-Mechanical Drive (EMD) starter-generator belt drive systems allow the engine to stop when the vehicle is stationary, then restarts the engine almost instantaneously. EMD spins the engine to a very high cranking speed enabling a rapid, silent and fuel-efficient start.
Both emissions and fuel consumption are reduced with the EMD stop/start operating strategy. Independent studies have shown fuel savings of 6-10%, depending on the application, and even more than 20% savings in urban traffic.
The EMD system offers the potential to recover braking energy and to use stored electricity to boost acceleration. The system can schedule the generation of electric energy to times when it is cheap to produce, i.e. usually events of vehicle deceleration when no fuel is injected and the engine brakes the vehicle.
EMD is applicable with either 14 or 42 volt systems. The EMD system will be used in the 2007 Saturn Vue and 2007 Chevrolet Malibu, according to Gates.
The Gates E3 Drive is a two-speed drive system that allows accessories such as the air conditioning compressor and alternator to operate at idling speed, where fuel is used most efficiently by these accessories, while the engine still operates at drive speed.
The driver will not notice a difference in the vehicle operation but will see their fuel consumption reduced by 5% or more, according to Gates. The system is compatible with other fuel consumption reduction technologies and Gates is working with truck and auto manufacturers to implement the E3 Drive. It is also a simple aftermarket solution.
The CabRunner Integrated Power System reduces fuel use and emissions by eliminating the need for semi-truck drivers to idle their engine while sleeping during a long-haul trip in order to power cab accessories such as air conditioning, heat and lights. The CabRunner IPS powers all the truck’s accessories when the truck engine is not running.
CabRunner IPS consists of a small, two-cylinder diesel, a reconfigured Accessory Belt Drive System (ABDS) and a pulley system design that allows either the CabRunner IPS or the truck engine to operate the ABDS. On the highway, the truck engine is in control. In the parking lot, the CabRunner IPS diesel takes over.
The CabRunner can reduce idling fuel consumption by 60% and greatly reduce the idling emissions.
Gates also highlighted other technologies and products to meet new fuels and emissions standards, such as Gates Hybrid Hydraulic technology and Gates diesel hose product line.
We recognize the importance of energy consumption reduction and are looking to do our part to help. We plan to continue developing energy saving and pollution reduction technologies for today’s vehicle designs and equipment so they can be deployed now.—Marco Moran, President, Gates Worldwide Power Transmission Division
