What was the Detroit Diesel Electronic Control System?
What was the Detroit Diesel Electronic Control System?
This innovative system, the Detroit Diesel Electronic Control system, or DDEC, allowed for greater control of injection timing and maintenance monitoring. It also allowed for advancements that helped engines keep up with emission regulations put forth by the EPA.
Are there any problems with the Detroit Diesel 14L?
Another common complaint, especially with the 14L, is poor fuel economy. As the engine got bigger and was designed for more horsepower, fuel usage seemed to increase as well. Some argue that this lowering of fuel economy is not due to engine design, but to poor operating practices.
When did the Detroit Diesel engine come out?
Debuting in 1986, these engines were the first diesel engines to feature an electronic control system. This innovative system, the Detroit Diesel Electronic Control system, or DDEC, allowed for greater control of injection timing and maintenance monitoring.
When did Detroit stop using the DDEC system?
More changes have been made to the DDEC systems recently, in order to increase engine efficiency and power, and as is the case with the DDEC VI, to meet new emission standards. These ECUs can be found in the later Series 60 14L applications, before the line was discontinued in 2011.
What kind of electronic control does Detroit use?
Despite its initial development for the Series 60, DDEC units are still being used in Detroit’s DD line of engines. And Detroit no longer has the the only engines on the market with ECU’s. Electronic control is the standard of modern diesel engines.
What happens when a cruise control switch fails?
If the cruise control switch fails, it will not be able to deactivate the cruise control system when the brake pedal is depressed. This will cause the vehicle to continue to accelerate as the brakes are being applied, which can cause them to overheat and damage the components.
Where is the fuse on the cruise control?
Figure 1. A good fuse (on the left) compared to blown fuses (on the right). This switch is located on the brake pedal assembly and allows current to flow to the cruise control module to signal cruise deactivation.
How does cruise control work in a car?
The cruise control feature works to maintain the vehicle at a constant speed without the need to step on the accelerator pedal. Once activated, the cruise control system will keep the vehicle at a constant speed or rate of acceleration until it is switched off manually or the brake pedal is stepped on.
