REV: 04-29-25 LF ENGINE PROGRAMMING HIGH IDLE SPEED The engine high idle control shall maintain the engine idle at approximately 1250 RPM when engaged. ENGINE HIGH IDLE CONTROL The vehicle shall be equipped with an automatic high-idle speed control which shall be pre-set to operate the engine at a specified RPM to increase alternator output if the system voltage drops to 12.5 volts with multi-plex wired chassis and 12.8 volts using load manager with conventional wiring. This device shall automatically operate only when the engine is running, the transmission is in neutral, and with the parking brake set. The automatic high idle will stay engaged for a minimum of ten (10) minutes and until the system, voltage has reached 13.0 volts. Application of the service brake will override the automatic high idle and reset timer. The vehicle shall be equipped with a high-idle speed rocker switch. It shall be pre-set so when activated, it will operate the engine at the specified RPM to increase alternator output. This device shall operate only when the engine is running, the transmission is in neutral, and with the parking brake set. When automatically engaged the high idle shall disengage when the operator depresses the brake pedal, or the transmission is placed in gear, and shall be available to manually or automatically re-engage when the brake pedal is released, or when the transmission is placed in neutral. Switch shall not override automatic high idle between voltage parameters during timed cycle. ENGINE PROGRAMMING ROAD SPEED GOVERNOR The engine shall include programming which will govern the top speed of the vehicle. AUXILIARY ENGINE BRAKE A compression brake, for the six (6) cylinder engine shall be provided. A cutout relay shall be installed to disable the compression brake when in pump mode or when an ABS event occurs. The engine compression brake shall activate upon 0% accelerator when in operation mode and actuate the vehicle’s brake lights. The engine shall utilize a variable geometry turbo (VGT) as an integrated auxiliary engine brake to offer a variable rate of exhaust flow, which when activated in conjunction with the compression brake shall enhance the engine's compression braking capabilities. AUXILIARY ENGINE BRAKE CONTROL An engine compression brake control device shall be included. The electronic control device shall monitor various conditions and shall activate the engine brake only if all of the following conditions are simultaneously detected: •A valid gear ratio is detected. •The driver has requested or enabled engine compression brake operation. •The throttle is at a minimum engine speed position. •The electronic controller is not presently attempting to execute an electronically controlled final drive gear shift. •There is no active ABS event.
