Variable geometry turbochargers have not always been the best in terms of reliability. But not all VGT’s are bad. It is a complicated problem that requires a complicated solution. Manufacturers have been handed the task of making diesel engines more efficient and produce fewer emissions. This is where components such as a variable geometry turbo come into play.
Problems with injector cups is a common issue on the Caterpillar 3406E. We know how frustrating it can be, especially if it happens soon after an injector replacement.
An EGR (exhaust gas recirculating) cooler is another way that engine manufacturers have been able to lower today’s emissions standards. Its main job is to remove as much heat out of the spent gasses as possible before re-entering the engine’s combustion chamber.
The Cat C15 ACERT engine is the pinnacle of diesel engine technology. That being said, even Caterpillar engines will come to a time where it needs to be serviced. Problems such as poor performance and excessive fuel consumption are just some of the common signs that your fuel injectors are not working within specs.
