JCB aims high with six-cylinder Dieselmax 672 engine

• In just over eight years, JCB has gone from being new to the field of engine manufacturing to a major global engine producer with a reputation for fuel efficiency and innovation.

JCB has announced plans to begin production of six-cylinder engines with the addition of the JCB Dieselmax 672 to its world-leading engine line-up.

The introduction of the engine represents an investment of around $68.5 million. By the time the engine goes into full production later this year, its launch will have created more than 50 new jobs.

In just over eight years, JCB has gone from being new to the field of engine manufacturing to a major global engine producer with a reputation for fuel efficiency and innovation.

The first engine rolled off JCB’s UK production line in November 2004. In 2011, JCB began producing engines at its Indian headquarters in Ballabgarh. To date, JCB has produced more than 250,000 engines globally.

“In a relatively short space of time we have become a major producer of engines and today more than 70 percent of JCB’s machines are powered by the engines we manufacture,” said JCB Chairman Sir Anthony Bamford. “The move into six-cylinder engine production is a historic moment for our business and a natural step to take. We look forward to setting new standards in performance and fuel efficiency.”

The JCB Dieselmax 672 is based on the company’s successful four-cylinder 4.8-liter Dieselmax engine, with a high degree of parts commonality across the two engine platforms.

The Dieselmax engine has been in production for more than eight years, with many engines worldwide running reliably after more than 20,000 hours of service. Today’s Dieselmax features electronic control, Delphi common rail fuel injection and fixed geometry turbocharging.

Initially, the Dieselmax 672 will be produced to meet Stage II emissions standards for growth markets including Russia, Brazil and China.

The engine will be seen first in JCB’s JS360 crawler excavator for those territories, but will also be used in additional machines as time progresses.

The six-cylinder engine will be offered with ratings of 188hp, 221hp, 255hp and with a maximum output of 302hp. Maximum torque is an impressive 885 lbf-ft. More impressive still, JCB has managed to produce an incredibly efficient engine in the Dieselmax 672, promising up to an 8 percent increase in fuel efficiency compared to previous engines in the JS excavator line.

In testing, the 7.2-liter engine has recorded a specific fuel consumption of just 189g/kWh while delivering excellent performance and rapid response.
