Did you know that the Engine Idle Temperature Management System (EITMS) on Harley Davidson motorcycles can reduce engine heat by up to 100 degrees Fahrenheit?
Imagine the impact of such a feature on your riding experience, especially during those long idling periods or stop-and-go traffic situations.
Curious to learn more about how EITMS functions and the benefits it offers in terms of rider comfort and control over your Harley Davidson?
You're about to uncover a whole new level of understanding and appreciation for this innovative technology.
Key Takeaways
- EITMS on Harley Davidson regulates rear cylinder temperature for optimal performance and rider comfort.
- EITMS works by deactivating the rear cylinder fuel injector during extended idling or slow-speed situations.
- Benefits of EITMS include reducing engine heat buildup and utilizing the rear cylinder as an air pump for cooling.
- Riders can manually control EITMS activation based on specific idle conditions and temperature thresholds.
Overview of EITMS on Harley Davidson
EITMS on Harley Davidson, short for Engine Idle Temperature Management System, actively regulates the rear cylinder's temperature during extended idling or slow-speed situations by disabling the rear cylinder fuel injector. This system is crucial in managing engine temperature, especially under idle conditions where heat buildup can be problematic. By temporarily turning off the fuel injector for the rear cylinder, EITMS helps prevent overheating and ensures optimal performance.
During periods of idle or slow speeds, such as in heavy traffic or when waiting at a stoplight, EITMS kicks in to cool down the rear cylinder. This is particularly beneficial in hot weather conditions or when the engine is under stress due to prolonged idling. By enabling EITMS, riders can enhance their comfort and avoid potential issues related to excessive heat buildup in the engine.
In essence, the Engine Idle Temperature Management System on Harley Davidson motorcycles plays a vital role in maintaining the engine's temperature equilibrium and ensuring a smooth riding experience, especially in challenging conditions where heat dissipation is critical.
How EITMS Works on Harley
When the Engine Idle Temperature Management System on Harley-Davidson motorcycles is activated, it cools the rear cylinder by deactivating the rear cylinder fuel injector during extended idling or traffic situations. The system kicks in when the engine temperature reaches a critical point, ensuring optimal performance and temperature regulation.
Here's how EITMS works on your Harley:
- Precise Control: EITMS is enabled at idle twist grip, vehicle speeds under 1 mph (2 km/h), and engine RPM under 1200, allowing for precise management of engine temperature.
- Customizability: Riders have the ability to enable or disable EITMS using a specific procedure involving throttle position and indicator lamp response, giving you control over your riding experience.
- Efficient Cooling: EITMS alters idle cadence, maintains idle speed, and ingeniously uses the rear cylinder as an air pump to cool the engine during idle, ensuring your bike stays green and ready for action.
Understanding how EITMS functions empowers you to optimize your Harley's performance and temperature regulation as you cruise the open roads.
Benefits of EITMS Feature
Utilizing the Engine Idle Temperature Management System (EITMS) on your Harley Davidson provides significant advantages in controlling engine heat during idle or low-speed scenarios.
The EITMS feature helps reduce heat buildup in the engine by cooling the rear cylinder when the temperature surpasses 165°C. By turning off the fuel injector in the rear cylinder, the system utilizes it as an air pump for heat dissipation, enhancing engine temperature management.
This capability is particularly useful in hot weather or heavy traffic situations, where engines are prone to overheating. Riders can manually enable or disable EITMS based on their preferences, giving them control over their riding experience.
EITMS Activation and Deactivation
During engine operation on your Harley Davidson, the system for managing idle temperatures automatically activates when specific conditions are met. Here's what you need to know:
- EITMS Activation: When the engine temperature rises above 165°C and certain idle conditions are satisfied, the EITMS kicks in. This involves shutting off the rear cylinder fuel injector to aid in cooling the engine during idle or low-speed situations.
- Deactivation Factors: EITMS deactivates when the engine temperature falls below 135°C, or if there are changes in throttle position, speed, RPM, or clutch engagement. These alterations prompt the system to cease its cooling actions and resume normal operation.
- User Control: Enabling or disabling the EITMS feature requires following a specific procedure that involves monitoring throttle position and observing the indicator lamp response. This hands-on approach gives riders the autonomy to manage the system based on their cooling needs while riding their Harley Davidson.
EITMS Compatibility and Availability
EITMS Compatibility and Availability extend across Harley-Davidson models with Twin Cam engines from 2008 to 2016 and all Milwaukee-Eight engine-equipped bikes since 2017. These systems are compatible with Harley-Davidson softails and touring models that feature fly-by-wire technology. As a rider, you have the freedom to manually activate or deactivate the EITMS based on your preferences and the specific riding conditions you encounter. Monitoring and adjusting the EITMS status is conveniently done through the bike's infotainment system or dashboard display.
To provide a clearer overview, here is a table detailing the compatibility and availability of EITMS on different Harley-Davidson models:
| Harley-Davidson Model | Engine Type | EITMS Availability |
|---|---|---|
| Touring Models | Twin Cam (2008-2016) | Yes |
| Touring Models | Milwaukee-Eight (2017+) | Yes |
| Softail Models | Milwaukee-Eight (2017+) | Yes |
With this information, you can ensure that your Harley-Davidson bike is equipped with EITMS and take full advantage of its capabilities for a more controlled and enjoyable riding experience.
Conclusion
In conclusion, the Engine Idle Temperature Management System (EITMS) on Harley Davidson motorcycles is a valuable feature that enhances rider comfort by cooling the rear cylinder during idling or slow-speed situations.
With the ability to easily enable or disable EITMS, riders have more control over managing engine temperature and overall riding experience.
So, next time you hit the road on your Harley, rest easy knowing that EITMS has your back, keeping things cool like a vintage ice cream parlor on a hot summer day.
