The JCB Engine Timeline: 1871 – 2024

Bamfords Ltd. started diesel engine manufacture in 1932 with three models of 6, 8 and 10hp. These engines were an immediate success and gained top honours at shows in the UK and Ireland. Meanwhile, Joseph Cyril Bamford, who had been in the family business since 1935, left to start his own successful manufacturing company J. C. Bamford Excavators Ltd in 1945.




This JCB 4000 engine uses a mechanical fuel injection
system, rated at 55kW, as shown in this early prototype
built in 1986.

This rapid prototype JCB DIESELMAX engine was
to be the start of the DIESELMAX project.

“The JCB diesel engine is a project very close to my heart”,
Lord Bamford said in 2005. “My father always wanted to
manufacture his own engine and he developed a number of
prototypes. However, the high costs ruled it out – until now.”system, rated at 55kW, as shown in this early prototype
built in 1986.


The racing engines generated
more than five times the power
of the production version and at
150bhp/litre, were the world’s
highest specific power diesel
car engines. The photographs
above show part of the engine,
including the immense fuel rail,
and Anthony Bamford directing
the design of the car.
