Kenworth is expanding its popular Engine Auto Start and Stop monitoring system capability. In addition to detecting when batteries get to a critical level, Kenworth’s Auto Start and Stop can now detect when engine oil temperature dips to a point where it could cause fuel gelling.
Initially introduced last fall as an option for its on-highway flagship Kenworth T680 in sleeper configurations, Kenworth now has added the optional Engine Auto Start and Stop for its vocational flagship Kenworth T880 with sleepers. The option may be ordered with or without the Kenworth Idle Management System, a battery-based APU system. In addition, Kenworth has added the engine monitoring system to include Kenworth T680 and T880 day cabs.
“Our system is proactive. Instead of shutting down battery draws, or letting the engine oil temperature get to a state of no return, Auto Start and Stop automatically starts the main engine to keep all systems going. Once at a designated level of charge or oil temperature, the engine shuts down,” says Jason Skoog, Kenworth Assistant General Manager for Sales and Marketing.
“This is a great feature, especially for those running in climates where fuel gelling may be an issue,” continues Skoog. “This will help ensure trucks are ready to roll regardless of winter conditions.”
The truck operator does not need to be with the truck for auto start/stop to be engaged. “The truck is in auto-pilot, so if the driver is off-site or eating dinner for example, the truck will turn on to recharge the batteries and get engine oil back to a normal operating temperature,” explains Skoog. “There are safeguards in place, so the truck cannot be moved or stolen when the auto start feature is activated.”
For added battery monitoring, the Kenworth Driver Performance Center on the Kenworth T680 and T880 provides the operator with real-time information on the battery state of charge and oil temperature. “This is very useful, especially with our Kenworth Idle Management System. When the engine comes on for recharging, the driver can watch the progression,” says Skoog. “If only an hour or two more power is needed before leaving to deliver a load, the driver can shut down the system early and use the battery power, then recharge the battery banks while on the road.”
