Testing the first Bosch diesel injection pump in a car (brand Stoewer), 1927

Around 1920, experts were vaunting the diesel engine as the powertrain of the future. Bosch realized how significant it was. The electric ignition, the most important part of the product portfolio, was not necessary in a diesel engine. Bosch faced a dangerous situation for his company and made a decision: He officially started developing diesel injection pumps in 1922. The first diesel truck was rolled out in Germany in 1924, enabling Bosch to test its new pumps under normal driving conditions. Bosch gave the go-ahead for the series production of in-line injection pumps for trucks on November 30, 1927. In the same year, Bosch started to test diesel technology for passenger cars like shown in this picture. Series launch for cars came in 1936.
