IC Bus (Lisle, Ill.) said Feb. 23 that its CE Series school bus powered by Power Solutions International’s (PSI; Wood Dale, Ill.) 8.8-liter propane engine is available for order. The CE Series PSI heavy-duty propane engine is said to offer a cleaner, quieter, and more user-friendly alternative to diesel that won’t sacrifice power, torque, or durability.

“The CE Series bus was purpose-built for the school bus industry and we’re proud of the advancements we continue to make in order to meet our high standards and those of our customers for safety, quality, and envi­ronmental impact,” said Trish Reed, vice president and general manager of IC Bus. “Each IC Bus is built to meet the needs of the customer, providing superior performance, outstanding durability, remarkable fuel economy, and a national network of dealers for service and support.”

The PSI 8.8-liter propane engine is engineered to deliver the highest torque at the lowest speed. The design benefits stop-and-start applications to allow immediate acceleration after stops and greater hill-climbing capabil­ity. This also eliminates excessive noise, heat, and vibration associated with constant engine revving. Minimal revving reduces engine wear, oil usage, and maintenance, while increasing durability and efficiency.

The CE Series school bus was designed based on the needs of customers, focusing on passenger safety, driver comfort, vehicle durability, and serviceability. CE Series school buses are built with 16-gauge steel side rails and an 18,500-lb rear steel spring suspension. Safety features include a Leave No Student Behind alarm system that requires the driver to disable an alarm at the rear of the bus before existing the vehicle, ensuring no student onboard is overlooked.
