Zexel was founded in Japan by Isuzu Motors Ltd. in 1939 as Diesel Kiki Co. supplying injection pumps under licence from Robert Bosch GmbH. In 1990 the company was renamed ZEXEL and in 2000 Bosch and Valeo of France bought the company. Robert Bosch GmbH has retained use of the Zexel brand name up to this date and often Bosch parts have a Zexel equivalent
