I’m of the mind, “Let the truck driver decide on the actions of the truck he’s driving”.
For a bit of background, I’ve never been in favour of emission friendly engines, CARB and other such programs.
This factor was a deciding factor for me, when I retired from trucking in California. I wasn’t prepared to spend hundreds of thousands of dollars to update my truck and trailer unit, just because of the California C.A.R.B. regs.
I loved trucking in California and hauling produce but it just didn’t pay enough for me to continue. The investment was too huge to justify.
The problem with the new emission friendly engines? There was something that worked very well and was monkeyed with, in an attempt to improve it, aiming for zero emissions.
There has been so much trouble with these engines ever since they started changing with them.
I ran into a friend today, with a 2015 Peterbilt with a Cummins engine. He was travelling in the Rocky Mountains in B.C. The turbo on his truck has a gate which opens and closes in order to control the emissions.
The gate on the turbo malfunctioned, slammed shut, shut the turbo down and in return shut the engine down to the point where it was loosing serious power. There was enough power reduction, that it shut down the jake brake.
The driver was on a downhill grade on the Salmo Cresent, on an 8% grade, pulling a set of trains when this engine decided to shut down and cut off the jake.
My friend, fortunately is an excellent driver. However, this situation could have been deadly! He managed to drive his way out of the situation and get slowed down and stopped safely.
He is a heavy mechanic by trade so he had all his trailer brakes adjusted the way they should be. He was able to drive himself out of danger. However, not everyone would have been able to do this and had their brakes set up as well as he did. This could have been a big disaster.
Here lies one of the serious problems…. one of the many serious problems with these newer style emissions engines!
They are not reliable and they are making decisions for the driver. The engine in this case decided it was in trouble and shut itself down.
I say let the truck driver decide. This should have been solely the driver’s call, not the engine’s call. It would have been safer had the truck given a warning sound or signal but NOT kill the jake brake on a mountain when the truck is headed downhill with trains!
I say throw out CARB and these new style engines and go back to the engines that work and get back to trucking again.
