Innovative Thermal Management Module Reduces CO2 Emissions by up to 4 Percent

The Schaeffler Group has developed a new temperature control system for automotive engine and transmissions. The system plays a key role in reducing CO2 emissions by up to 4 per cent for both internal combustion engines and hybrid electric components and batteries. The system is also ideal for use on engines with start-stop functionality.

Launched at this year’s IAA Frankfurt Motor Show, Schaeffler’s new Thermal Management Module is an innovative temperature control unit for the entire vehicle drive train. The module combines numerous functions into a single compact, integrated unit housed in a high-strength plastic enclosure.

Up to now, the temperature of almost all internal combustion engine-driven vehicles has been controlled by a thermostat mounted on the engine block. The engine is typically cooled by circulating water from a pump. The water pump operates continuously regardless of engine load. Even on engine start up when the engine is cold, the pump continues to operate – which is inefficient.

Schaeffler’s Thermal Management Module precisely maintains the temperature of all drive train components according to requirements by electronically controlling cooling water distribution. This enables the engine to operate at the optimum temperature in response to changing engine load and driving conditions. For example, the cold running phase can be significantly reduced by switching off the water pump at engine start up. Individual components can also be run at higher temperatures than is possible in a thermostat-controlled engine. Engine temperature can be reduced under full load and the tendency for ‘knocking’ or having to enrich the fuel mixture under full load is also reduced using the Thermal Management Module.

By using a rotary slide valve, the Thermal Management Module is able to quickly reach the optimum temperature range for the engine and transmission. This has a positive effect on both the energy efficiency and life expectancy of components in the drive train. Turbocharger temperature can also be individually controlled by the module, ensuring after cooling of the thermally stressed, exhaust gas turbine.

The sensor-controlled Thermal Management Module enables the speed of the electronic water pump to be increased or decreased depending on the driving conditions. At full speed, the temperature of the engine can be decreased by the control module so that the fuel mixture doesn’t need enriching, which in turn reduces fuel consumption. Driving at part-load means the temperature of the engine can be increased by the control module, enabling the optimum fuel mixture to be achieved.

The new module opens up a raft of opportunities for vehicle designers to improve the energy efficiency of both engines and heating & cooling systems for transmission and turbocharger units. For example, the module can be used to precisely control the temperature of alternators, hybrid modules and batteries, efficiently cooling or heating these systems according to individual engine requirements.

“The performance of the thermal management module makes this component particularly suitable for use in engines for start-stop operation,” commented Prof. Peter Pleus, President of Schaeffler Group Automotive.

Like all Schaeffler-manufactured engine components and bearings, the individual components of the Thermal Management Module are friction-optimised for increased energy efficiency. Due to its low power consumption, the module can be fitted directly to the engine control unit without having to introduce additional power stages.

The Thermal Management Module releases the shackles from vehicle developers, who were previously constrained to fitting the temperature control unit or thermostat close to the engine block. Standard, interchangeable hoses ensure that assembly times for the module are minimised, as well as ensuring high sealing integrity.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin
