JCB has announced that it will produce a six-cylinder, 7.2 litre Dieselmax engine, following a $70 million (£45m) development investment, at its JCB Power Systems’ engine plant in Derbyshire, UK.

The Dieselmax 672 six-cylinder engine will be offered with ratings of 140kW, 165kW, 190kW and with a maximum output of 225kW. The engine features electronic control, Delphi common rail fuel injection and fixed geometry turbo charging. Maximum torque is 1,200Nm.

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

The engine will be seen first in JCB’s JS360 crawler excavator, currently built with a 6-cylinder Isuzu engine, but will be rolled out in additional machines over time.

The 672's architecture is based on the company’s four-cylinder 4.8-litre Dieselmax engine, boasting a high degree of parts commonality across the two engine platforms.

With a development phase stretching across two years, the 672 has completed more than 50,000 hours of testing, 30,000 of which have been in machines working in the field.

The Dieselmax engines have 500-hour service intervals, and will also be offered as part of the company’s OEM product line, for use in non-JCB machinery.

JCB Chairman Sir Anthony Bamford praised the process, which will see up to 50 new jobs created at the Derbyshire factory.

"In a relatively short space of time we have become a major producer of engines and today more than 70% of JCB’s machines are powered by the engines we manufacture. The move into 6 cylinder engine production is a historic moment for our business and a natural step to take and we look forward to setting new standards in performance and fuel efficiency.”

JCB began producing engines in 2004, and in 2011 began production at its India headquarters in Ballabgarh. To date it has built more than 250,000 engines globally.
