The structure of the circuit differs in vehicles with automatic transmission and gear change. To avoid accidental shifting in vehicles with automatic transmission, a fail-safe component – also known as Brake Transmission Shift Interlock or BTSI – must be integrated into the circuit.
For many years, ETO has been a competent development partner of valves and sensors used in air suspension systems.
Air suspension is a market that is constantly growing: More than 1 million systems are built worldwide every year. The main focus is on safety, comfort and dynamics.
We develop individual solutions for our customers for stand-alone pressure sensors and valve modules with integrated actuators and sensors, which are characterised by the highest quality, service life and performance.
Variable valve timing is part of the variable valve train and serves to increase the efficiency of a combustion engine. This enables us to achieve a higher performance and torque whilst at the same time reducing CO2.
Proportional solenoids by the ETO GRUPPE ensure optimum control and regulation of a hydraulic cam phaser, also known as a variator.
Canister vent valves are used in evaporative emission control systems and play an important part in meeting the OBD-II requirements in the USA and Korea.
Our solenoid valve has been successfully in use for over 15 years. We are always developing the design even further so that we are able to offer a product in the highest quality, with the best performance and at competitive prices.
In the field of gear and clutch systems, ETO offers fully integrated modules from solenoid valves and sensors (speed, pressure and displacement sensors). With our holistic solutions tailored to your individual needs, we reduce the interfaces for our customers of automated commercial vehicle gear and clutch systems and thus also the costs.
3/2 stand-alone valves and stand-alone speed and pressure sensors are used in every medium and heavy-duty commercial vehicle, as well as in virtually all semitrailers and trailers. Thanks to a high level of flexibility, ETO products can be used for a variety of applications.
ETO pressure sensors for pneumatic and electronically controlled air suspension systems (air suspension systems for level control) are used in towing vehicles, semitrailers and trailers. The sensors record the bellows and system pressures of the vehicles. In accordance with the vehicle load, the deflection height of the air suspension can be controlled using supply and exhaust air through the ETO solenoid valves. Tractors and trailers can thus be regulated on all axes and driven with a high level of comfort. As well as this, the combination and tuning of the air suspension with the braking systems creates a substantial safety advantage compared to vehicles without air suspension.
ETO pressure sensors are sustainable and environmentally friendly solutions: The aerodynamically optimised settings reduce the fuel consumption and the emission of exhaust gases.
One of our core competencies within commercial vehicle applications is solenoid valves and pressure sensors for ABS (anti-lock braking systems) and EBS (electronic braking systems), which can be used as individual systems or fully integrated modules. Our solutions are used in truck and trailer applications and enable safe breaking within the customer’s systems.
When it comes to valve stroke and phase switching, significant reductions in consumption and emissions are obtained in modern petrol and diesel engines, whilst at the same time maintaining an advantageous system complexity. This includes using cylinder deactivation as an important downsizing measure, switching the combustion process or internal exhaust gas recirculation, to name just a few methods.
We supply electromagnetic actuators that are perfectly tailored to the customer application, are extremely robust and have been proven with millions of units.
Ten years of experience in development and series production makes us a passionate world market leader for valve stroke actuators.
