Over 200,000 Dieselmax engines have now been produced by UK manufacturer JCB.
Following years of development and an £80 million investment, the first JCB engine rolled off the line in November 2004 at JCB Power Systems in Foston, Derbyshire.
Now 170,000 have been produced at Foston and another 30,000 in India, where manufacturing began in April last year.
JCB director of engine programmes Alan Tolley said: “Since 2004, the JCB Dieselmax engine has earned an unrivalled reputation for reliability and durability in the off-highway sector. It has also given JCB complete control over its destiny in powertrain technology.”
