Fuel injector solenoid driver


















The common-rail system with pressure-compensated solenoid injectors by Bosch enables the flexible injection of fuel at pressures up to 2, bar. Even greater economy and precision The “Digital Rate Shaping” strategy (DRS) contributes to a very small delay between pre-injection and main www.doorway.ru: Common-Rail System With Solenoid Injectors. excellent control of fuel injector drive circuitry in • 22 mA Output Drive Current modern automotive systems.

A fuel injector is just an electric solenoid that opens a valve. A solenoid is a coil with a lot of inductance. When power was removed a reverse polarity, inductive spike is created by the collapsing magnetic field. This spike could be a relatively high voltage which induced noise into wires of close proximity. “No biggee,” I said.

Solenoids are used to activate four-wheel drive system, fuel injection systems, locking the doors of the car and controlling the air flow in the vehicles air conditioning system. The vast number of valves in the vehicle are also controlled by solenoids. 2. Solenoid operating principles.


Fuel pumps and fuel injectors are two essential parts of cars today. Both components have similar characteristics. However, they perform very different functions during an engine's normal operating cycle. Fuel pumps and fuel injectors are t. Experts suggest that finding the best diesel fuel additive for your diesel engine depends on several factors, including your vehicle’s make and model and the type of additive. If you’re looking for a good diesel fuel additive, then use this. If you’re wondering where to buy kerosene fuel, you’re probably heading out on a camping trip, using kerosene as an alternative to natural gas in your heater or setting up your emergency lamps for bad weather. Kerosene fuel is versatile and.
