Technical Components of RAM Etorque Systems

RAM Etorque systems combine advanced electronics with hydraulic components to deliver precise control over torque and pressure. At the core of these systems is the electronic control unit (ECU), which monitors various inputs such as engine speed, load, and user commands. The ECU processes this data in real time to modulate the hydraulic pressure applied by the RAM Etorque pump, optimizing performance and efficiency.

The key components include:

  • Electronic Control Unit (ECU): Acts as the brain of the system, executing control algorithms and managing sensor inputs.
  • Hydraulic Pump: Typically a variable displacement pump that adjusts fluid flow and pressure based on ECU commands.
  • Sensors: Monitor parameters like pressure, temperature, and engine speed to provide feedback to the ECU.
  • Actuators: Devices that receive signals from the ECU to adjust hydraulic components accordingly.

Together, these elements enable the RAM Etorque system to respond dynamically to changing conditions, ensuring that torque delivery is smooth, efficient, and aligned with the vehicle’s operational requirements.

Operational Principles Behind RAM Etorque

The RAM Etorque system operates by continuously adjusting hydraulic pressure to control torque output. This is achieved through a closed-loop feedback system where sensors constantly relay data to the ECU. The ECU interprets this data against set parameters and adjusts the hydraulic pump’s output accordingly.

The process includes:

  • Measuring the current torque demand and engine conditions.
  • Calculating the optimal hydraulic pressure needed.
  • Adjusting the pump displacement to increase or decrease flow.
  • Monitoring system response and making further adjustments as needed.

This method allows for precise control, reducing energy waste and mechanical wear, and enhancing overall vehicle responsiveness.

Benefits of Using RAM Etorque Technology

RAM Etorque technology offers several advantages over traditional torque control systems:

  • Improved Fuel Efficiency: By optimizing hydraulic pressure and torque delivery, the system minimizes unnecessary power consumption.
  • Enhanced Performance: Precise control allows for smoother acceleration and better traction management.
  • Reduced Wear and Tear: Dynamic adjustments reduce mechanical stress on drivetrain components.
  • Lower Emissions: Efficient torque management contributes to decreased exhaust emissions.
  • Increased Reliability: Electronic monitoring and control help prevent system overloads or failures.

Its adaptability and precision make RAM Etorque suitable for any application requiring efficient torque management under diverse operating conditions.

How RAM eTorque Technology Functions

RAM eTorque is an advanced mild hybrid system integrated into RAM trucks, designed to enhance performance, fuel efficiency, and driving smoothness by supplementing the internal combustion engine with electric power. The system primarily revolves around a belt-driven motor-generator unit (MGU) that replaces the conventional alternator.

The core operational principles of RAM eTorque involve:

  • Regenerative Braking: The MGU captures kinetic energy during deceleration and braking phases, converting it into electrical energy stored in a 48-volt lithium-ion battery pack. This process recovers energy that would otherwise be lost as heat.
  • Electric Torque Assist: During acceleration or when additional power is required, the stored electrical energy is deployed via the MGU to provide supplemental torque. This reduces the load on the internal combustion engine, improving throttle response and lowering fuel consumption.
  • Engine Start-Stop Functionality: The eTorque system enables seamless automatic engine shut-off when the vehicle is stopped, such as at traffic signals, and rapid restarts when the accelerator is pressed. This reduces idle fuel consumption and emissions without compromising driver convenience.
  • Smoother Transmission Shifts: By providing additional torque and controlled power delivery, eTorque facilitates smoother gear changes in the transmission, enhancing overall driving refinement.
Component Function Benefits
Belt-Driven Motor-Generator Unit (MGU) Replaces alternator; generates and delivers electrical power Enables regenerative braking and electric torque assist
48-Volt Lithium-Ion Battery Stores electrical energy captured during braking Provides energy for torque assist and start-stop functions
Power Electronics Controller Manages energy flow between battery, MGU, and engine Optimizes power delivery and system efficiency
Start-Stop System Automatically shuts off and restarts engine Reduces idle fuel consumption and emissions

Operationally, the eTorque system continuously monitors vehicle speed, engine load, battery state of charge, and driver inputs through the vehicle’s electronic control units (ECUs). Based on this data, the system precisely controls when to harvest energy, when to supply torque, and when to engage start-stop functionality.

For example, during light acceleration, the eTorque system can provide up to 90 lb-ft of torque to assist the engine, effectively reducing engine load and improving fuel efficiency. During braking or coasting, the MGU switches to generator mode, recharging the battery with recovered energy.

Furthermore, the integration of the eTorque system into RAM trucks requires minimal changes to the vehicle architecture. The belt-driven design allows it to be retrofitted onto existing engine setups without extensive modifications, making it an efficient mild hybrid solution.
