FLEXIBLE POWER SOLUTION FOR BUSES, COACHES, AND SPECIALIST VEHICLES

28 March 2018
Cummins ISL is one of the most popular engines in the transit market due to its high reliability, low maintenance, and fuel efficiency. This provides a highly flexible power choice with a fuel-efficient 8.9 litre configuration. With a lighter weight than competitive engines, operators benefit from high performance, strong acceleration, and lower operating costs, all with the reliability and durability expected from Cummins.

Designed for medium and heavy duty, inner and intercity transit operations, Cummins ISL features targeted piston cooling, roller followers, and articulated pistons to increase durability. A combination full-flow and bypass oil filter extends piston ring and bearing life. Together with mid-stop cylinder liners, this also means that the Cummins ISL is easier to rebuild.

The ISL has been designed for medium and heavy-duty structural strength. It incorporates design features associated normally with larger Cummins engines, notes Cummins Sales and Business Development Manager Bo Fu (Bob). An enhanced camshaft and roller cam followers, a viscous damper, and high-capacity lube system enable Cummins to maintain high durability and reliability, in addition to a high power-to-weight ratio.

A high-efficiency lube cooler lowers oil temperatures for longer life, while Six Sigma design practices have resulted in enhanced reliability for individual components and total engine design. A crankcase ventilation system with a coalescing filter practically eliminates oil carryover. Coolant flow has been optimised and balanced, thereby effectively reducing cylinder temperatures.

 

Weighing in at just over 800 kg, the Cummins ISL offers significant benefits for payload-critical and high-bulk volume operations. With unrivalled levels of torque for an engine of this size, the Cummins ISL provides a flexible power solution for premium rigids, lightweight tractor units, higher-powered buses and coaches, and specialist vehicle applications.

Cummins ISL incorporates proven technologies and subsystems such as a cooled EGR, a patented VG Turbo, a high-pressure common rail fuel injection system, and a Cummins diesel particulate filter. These technologies have been used in Cummins transit bus engines for years. The VG Turbo, for example, adjusts airflow constantly to reduce turbo lag, in addition to providing for smooth acceleration.

The fact that there is only a single moving part in the hot exhaust stream means that the Cummins ISL is vastly more reliable and durable than competitive turbos. “We have produced more engines with particulate filters than any other manufacturer, earning a reputation for low maintenance and trouble-free operation,” Fu notes.

Cummins ISL also reduces both operating and maintenance budgets. Based on one of the most fuel-efficient engines available on the transit market today, it helps keep fuel bills low, while the long service and maintenance intervals translate into the lowest total cost of ownership for fleet owners.

Ratings from 250 hp to 330 hp provide cater for any transit bus, from 8.8 m through to 18 m articulated buses. Cummins ISL is also available in conventional driveline and hybrid-ready configurations. “Regardless of your specific requirements, the Cummins ISL is the right engine for every bus, every route,” Fu concludes.
