- Today, DENSO celebrated its 40th anniversary of its gasoline injection business at its Nishio Plan in Aichi, Japan. Earlier this year, the DENSO Group produced its 900 millionth injector its 250 millionth fuel pump.
“We now produce gasoline injection products in 10 countries and regions,” said Michio Adachi, senior executive director of DENSO’s Powertrain Control Systems Business Group. “The company strives to meet market demand for cleaner emissions and better fuel efficiency through the development of advanced technologies and continual improvement of monozukuri - the art of making things.”
DENSO’s History of Gasoline Injection Business:
In the early 1960s, to respond to the growing demand for cleaner emissions DENSO began researching fuel injection systems for gasoline engines. In 1972, the company began production of an electronic fuel injection system that more precisely controlled fuel injection. In that same year, the company started mass-producing injectors and fuel pumps. Since then, DENSO has reduced the size and weight of these products while improving their performance to meet stringent emissions standards and the demand for higher fuel efficiency.
In 1983, DENSO developed a fuel pump with the world’s lowest operating noise at time, which improved the driving experience for passengers. In 1999, DENSO developed the world’s first 12 nozzle orifices - when conventional injectors typically had four of them. Due to the smaller size of the nozzle holes, this injector atomization the fuel spray and therefore increased the engine combustion efficiency.
In 1996, DENSO started production of high pressure injectors and high pressure pumps for gasoline direct injection (GDI) engines. And in 2010, the company mass-produced a GDI injector with the world’s finest level of fuel spray at the time and an GDI fuel pump with the world’s highest pressure level.
About Electronic Gasoline Fuel Injection System
The electronic gasoline fuel injection system consists of injectors, fuel pumps, engine electronic control units (ECU), various sensors, and other components. DENSO started to produce engine ECUs in 1971. Since 1972, DENSO has used semiconductor devices and ICs developed and produced in-house, to increase the reliability of its engine ECUs. DENSO also introduced various sensors including air flow meters, O2 sensors, and air-fuel ratio sensors.
