Auto repair for cars with electronic diesel controlled systems

The diesel engine was developed by Rudolf Diesel who made this invention back in 1887. Rudolf’s diesel engine used the compression pressure-ignition principle that resulted in more heat generation. His engine was bulky with an inefficient injection pumps. This created the need to improve this engine to increase its efficiency and reduce its size. In 1922 Robert Bosch improved on diesel injection systems thus creating the prerequisites for the high speed diesel engines used in motor vehicles leading to the production of the first diesel car in 1936.1964 and the distributor pump is introduced with the first electronic diesel control (EDC) system been installed in 1983.

Currently, garages are confronted with advanced diesel injection systems, thus calling for a need for diesel specialists to invest in systems for diagnostic on diesel engines, besides acquiring or developing the know-how required for the efficient use of diagnostic systems.Previously, all the repair work performed on the diesel engine focused on one unit— the injection pump. If it was faulty, it would be removed, then the part dismantled, replaced any wear parts repaired, tested and calibrated before being returned to the workshop for installation.

Today, with the introduction of complex high-pressure diesel systems which are been used increasingly in car and truck engines, all the components in the engine are electronically networked by an electronic control unit making the conventional pump repair a thing of the past. The diesel injection system is now rapidly and efficiently tested through the use of the diagnosis tester in accordance with a defined software package program. These systems allow for the flexible matching through electronically stored maps. With the availability of full electronic control, the injection event is separated completely from the control of any mechanical device. The Timing, duration, quantity and rate are no longer dictated solely by mechanical means, but programmed into a computer. This way, only the faulty parts are detected and following the diagnosis, the system informs the mechanic of any repair works required. Electronically-controlled diesel injection systems can establish an exact calibration of the particular components and the finest mechanical tolerances in order to guarantee low consumption and emissions together with high performance while maintaining and matching the manufacturer's specifications. This can in effect increase fuel efficiency and lower consumption of all internal combustion engines of up to 15 per cent with improved cold-starting and reduce harmful emissions. Since all its data is stored in digitized form, the diesel injection system can also be easily interconnected with other vehicle systems. For example: exchange data with the anti-lock braking system (ABS) and traction control (ASR) and between the engine and the automatic transmission. The result, more flexibility in the parameter settings such as the start of injection, injection rate, direction of injection, injection pressure leading to more efficiency over a wide range of engine loads and speeds from cranking and start up all the way to full power.

It is therefore advisable that if you have a diesel engine car with an electronic diesel controlled system, to take it to a garage with a diagnostic equipment to detect and treat common diesel engine problems such as smoking, hard start, lack of power and heavy fuel consumption. You could be thinking of driving for a bargain quick fix to a jua kali garage, but trust me, cheap is not just expensive—it's detrimental to your car in the long run. And with just paying a little extra for a thoroughly and professionally done job from a larger garage with diagnostic equipment, you will end up saving a lot more for every mileage you travel. This is especially true for modern diesel cars that include Toyotas, Mitsubishis and Land Rovers
