Forty years since it introduced electronic fuel injection, Bosch continues to upgrade the technology as it supplies automobile manufacturers and the aftermarket around the world with the most advanced fuel injection systems available. Bosch provides the aftermarket with a comprehensive after sales service and replacement parts program ranging from the original D-Jetronic to the latest in Bosch technology systems.
The Bosch D-Jetronic, the world's first electronically controlled gasoline injection system in a mass-produced passenger vehicle, was introduced 40 years ago in a Volkswagen 1600 at the International Motor Show in Frankfurt in 1967. The original Jetronic has progressed through the continually modernized K-Jetronic, Mono-Jetronic, and Motronic with greater electronic control, and Gasoline Direct Injection (GDI) which is the most advanced and efficient fuel injection system available.
"The key benefit of Bosch Jetronic and its successors has been to reduce fuel consumption and emissions while at the same time enhancing gasoline engine performance and vehicle driveability," said Warren Suter, Director, Engine Management Systems for Bosch.nbsp;Newer features of the injection system alongside the electronic control have been the electric fuel pumps and solenoid-operated injectors."
Bosch currently supplies nearly 10,000 replacement parts related to gasoline fuel injection systems with the broadest line of injection-related replacement parts in the aftermarket. Bosch provides early and late model electronic fuel injectors, fuel injection control units, oxygen sensors, engine control sensors, fuel pumps, and ignition coils for conventional gasoline injection, and also components for gasoline direct-injection systems.
Second Generation Bosch Fuel Injectors
Bosch has launched a broader line of gasoline fuel injectors for current and older domestic and import vehicles. The first electronic fuel injection system utilized "EV1" injectors. The modern, second generation injectors (EV6), in widespread use on new cars since 1992, are stronger, more durable and efficient.
“The EV6 is ‘over molded’ to form a one-piece injector with no internal seals or seams to leak,” Suter explained. “With fewer parts it is naturally lighter, more compact and easier to install. The injector provides a greater fuel dynamic flow range and refined spray pattern for improved fuel atomization and mixture combustion. An improved seat design yields a more positive seal, and less current draw reduces the possibility of ECU failure. Further, its increased dynamic range provides smoother performance and better fuel metering throughout a broad RPM range. Plus its outstanding hot-fuel behavior reduces the formation of bubbles in hot fuel for improved driveability.”
Bosch’s new EV6 injectors are designed for installation in domestic and imported vehicles currently equipped with them, or interchanged with older-technology OE injectors in selected older vehicles. With their superior fuel flow and spray pattern, the EV6 should improve vehicle fuel and operating efficiency when replacing older-type injectors.
"Today's wide range of Bosch parts for all aspects of electronic gasoline injection systems reflects the wealth of experience gained by the leading original-equipment fuel management system supplier in the motor-vehicle sector," Suter noted.
Additionally, Bosch can provide genuine, low-cost Bosch Exchange parts for a variety of components, such as ignition distributors, fuel distributors, air-mass meters and ECUs.
The Bosch Group is a leading global supplier of technology and services. In the areas of automotive and industrial technology, consumer goods, and building technology, some 260,000 associates generated sales of 43.7 billion euros, or $54.9 billion. In fiscal 2006. The Bosch Group comprises Robert Bosch GmbH and its roughly 300 subsidiary and regional companies in over 50 countries. This worldwide development, manufacturing, and sales network is the foundation for further growth. Bosch spends more than three billion euros each year for research and development, and in 2006 applied for over 3,000 patents worldwide. The company was set up in Stuttgart in 1886 by Robert Bosch (1861-1942) as a “Workshop for Precision Mechanics and Electrical Engineering.
The special ownership structure of Robert Bosch GmbH guarantees the entrepreneurial freedom of the Bosch Group, making it possible for the company to plan over the long term and to undertake significant up-front investments in the safeguarding of its future. Ninety-two percent of the share capital of Robert Bosch GmbH is held by Robert Bosch Stiftung GmbH, a charitable foundation. The majority of voting rights are held by Robert Bosch Industrietreuhand KG, an industrial trust. The entrepreneurial ownership functions are carried out by the trust. The remaining shares are held by the Bosch family and by Robert Bosch GmbH.
In North America, the Bosch Group manufactures and markets automotive original equipment and aftermarket products, industrial automation and mobile products, power tools and accessories, security technology, thermo-technology, packaging equipment and household appliances. Bosch employs 24,750 associates in more than 80 primary and 20 associated facilities throughout the region with reported sales of $8.8 billion in 2006.
