From heavy-oil pumps to

Bosch diesel injection systems
In around 1920, experts were vaunting the diesel engine as the drive system
of the future. Bosch was quick to latch on to this trend, and 1922 marked
the official start of diesel injection pump development. Bosch started series
production of in-line pumps for trucks on November 30, 1927. Production for
passenger cars started in 1936. In the 1970s, Bosch solutions made the diesel
engine a firm feature of the “Golf class.” From the end of the 1990s, highpressure
injection systems such as common rail made the diesel into a highperformance,
eco-friendly engine, as a result of which its market share in
Europe rose to as much as 50 percent.
