What is bosch EDC?
EDC (Electronic Diesel Control) is an electronic engine-management system for diesel engines. Bosch introduces the first system of this type for passenger cars in 1986. Since 1989 it has also been used in commercial vehicles, where it has now become part of today’s benchmark equipment. EDC combines all control and regulation functions in one electronic engine control unit to which the injection system and a large number of sensors and actuators are connected.
Bosch EDC ensures perfect diesel injection control at all engine operating points. It evaluates in actual time sensor data on the temperatures of coolant, fuel and charge air as well as the quick engine speed, the place of the accelerator pedal and the intake air mass. From these values the EDC calculates the best possible injection process and the correct amount of fuel to be injected.
What is bosch EDC remap?
As a manufacturer develops a new car they have to take into consideration all of the conditions it might be subjected to in all of the regions in which they aim to sell this model. This means instead of just optimising the ECU’s program or ‘map’ to deliver the best performance or the mainly fuel efficiency they have to make compromises to the map to take into account these potential differing operating conditions. These could include sub-standard fuels, extremes in temperature and altitude, differing emission laws and even the possibility that vehicle may not be serviced on a regular basis and in accordance with the manufacturers recommended instructions. Electronic control unit remapping is taking a read from the ECU’s processing chip of the vehicles standard compromised map and adjusting different parameters within the map such as fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal control amongst others to free the true performance from the engine. It is a totally safe process as it is just giving the engine the performance it should have had in the first place before all the compromises were applied to the unique programming. Every engine will have its own unique map and by adjusting this we can fine tune the characteristics of the engine; unleashing more power and in many cases reduce fuel consumption too.
Benefits of bosch EDC remap When EDC Remap has been done to your turbocharged diesel engine, you can feel and enjoy Increased horsepower, Increased torque, Better throttle response, Smoother power delivery, Improved economy, Safer overtaking.
What type of system does bosch EDC have? Bosch EDC has electronic sensors for registering operating conditions and changes. Extensive array of physical inputs is converted into electrical signal outputs. Actuators or solenoids which change the control unit’s electrical output signal into mechanical control movement.ECM (Electronic Control Module) or Engine Electronic Control Unit (ECU)with microprocessors which process information from different sensors in accordance with programmed software and outputs required electrical signals into actuators and solenoids.
What is bosch EDC 15 injection system?
Bosch HDI EDC 15 consists of an Electronic control unit which analyses the information from the different Sensors, and then operates the injectors at the right moment. It also controls a Pressure regulator, the exhaust gas recycling electro valve and the turbo charging Pressure modulating electro valve.
What is bosch EDC 16? The innovative EDC 16 (Electronic Diesel Control) engine management system from Bosch has its first appearance in the V10-TDI- and R5-TDI-engines. Bosch Electronic Diesel Control 16 engine management system is designed to be compatible as both a single and double control unit concept. The real concept used depends on the number of cylinders in the engine.
What is bosch EDC 17? The EDC 17 (Electronic Diesel Control 17) controls each parameter that is important for effective, low-emission combustion. Because of the computing power and functional scope of the new EDC 17 can be modified to match particular requirements, it can be used very flexibly in any vehicle segment on the world’s markets. In adding up to controlling the exact timing and quantity of injection, exhaust gas recirculation, and manifold pressure regulation, besides it also offers a large number of options such as the control of particulate filters or systems for reducing nitrogen oxides. The Bosch EDC 17 determines the injection parameters for every cylinder, making exact adaptations if necessary.
This improves the accuracy of injection throughout the vehicle’s entire service life. As a result the system makes an important contribution to observing future exhaust gas emission limits. The improved control functions also open up potential for employing new combustion processes, with even cleaner emissions, such as the process known as “partially homogeneous combustion.”
Experts from both the Diesel Systems and Gasoline Systems Divisions at Bosch have worked together personally to develop the new generation of electronic control units. This implicated the development of a new and improved system architecture, prepared for future standards such as Autosar (Automotive Open System Architecture). The confirmed plug and housing design of the EDC 16 has been retained. The EDC 17 therefore satisfies both the present and the future requirements of an engine management system.
Saving fuel with EDC remap
As soon as we remap a vehicle, particularly when fuel saving is the priority we focus on improving the low end torque in particular and widening the power-band as far as we can.
This raise in low end torque will mean less throttle pedal input is required to maintain cruising speeds, when fully laden or when on a gradient. It will also mean that the vehicle will be more comfy in higher gears at slower speeds as well requiring fewer gear changes overall.
If you merge these factors with adjusting your driving style to make the most of the additional low end torque you will see an improvement in fuel consumption. This is most effective on turbo-diesel engines where the savings could be as much as 20%!
