1. Bosch cleverly invented the use of automotive air bag pre charged gas cartridges to stop the motion of table saw blades if an operator's hand made contact with the blade.

Bosch's air bag cartridge design saved the blade, and saved the fingers.
The problem was, the flesh detection technology that Bosch utilized to sense when the fingers were about to be cut was already patented by the competitor, called Saw Stop, which introduced the entire concept of safer table saws to market. Bosch built upon that idea, and introduced an improvement to the blade braking aspect, but Bosch refused to license the flesh sensing aspect from Saw Stop.
I was the monitor in our snowbird park's wood shop when one of the other monitors trip the Saw Stop. Sounded like a shotgun was fired. I hung the blade and stop module from the beam above the saw stuck together. It is a very nice saw. We have it built into a table big enough to rip a 4x8 sheet of plywood without needing some to catch the pieces.
He was cutting small pieces of wood for wooden toy and used a carpenter's pencil to hold the small piece to the saw fence as he pushed it threw. The lead in the paint on the pencil triggered the stop.

Well if you maintain your fuel filter with a quality filter NOT the 3 dollar junk E-Bay/Amazon filters and also buy quality fuel you won't have a problem.
If you are that worried about a CP 4.2 failure than buy a gasser not a diesel. It really is that simple.

Or buy a pre 2019 Cummins 6.7L and forget about the worries......:B - Me_AgainExplorer III

The failures of the early CP4's both 1 and 2's was the piston with a roller follower getting turned sideways to the pumps cam lobe. Bosch was unwilling to pay the holder of a patent to keep the piston from turning in the bore.
This may be the Edelbrock patent that Bosch was unwilling to pay royalties to use.

Bosch unwilling to pay license fees for patents sounds like a familiar pattern with Bosch.
Examples in the power tool industry include:
1. Bosch cleverly invented the use of automotive air bag pre charged gas cartridges to stop the motion of table saw blades if an operator's hand made contact with the blade. Bosch's design was actually preferable to the competitor's blade stopping technology which destroyed the teeth of the saw blade in order to stop it.

Bosch built upon that idea, and introduced an improvement to the blade braking aspect, but Bosch refused to license the flesh sensing aspect from Saw Stop.
Bosch lost every legal appeal in the multi year court battle that ensued, and Bosch was ordered to stop sale and pull all their "Reaxx" table saws off the US market. It's too bad, because had Bosch been willing to simply pay the license fee, Bosch would likely have outsold SawStop, because the cost of the blades that some woodworkers use exceed $200, versus $49 for an air bag cartridge.
2. Another example... Bosch once again very cleverly innovated a radically new design of sliding compound miter saw, that used an articulating axial glide arm instead of friction guide rails that typical sliding compound miter saws slide upon. Bosch's glide arm literally floats the saw head above the work, like a robotic arm functions in an automotive factory. No other powered miter saw on the market comes even close to the unique utility of the Bosch design.
However, when you buy this saw, the saw head will have a plastic blank cover plate where the laser guide beam would otherwise be located, and where indeed Bosch has a laser in every similar saw sold around the world except in the United States and Canada. Why is this? Because Bosch was unwilling to pay the license fee to whoever patented the use of a laser guide beam on a sliding compound miter saw.
This seems silly to me. Even the cheapest Chinese Harbor Freight sliding compound miter saws that cost a fraction of what the Bosch model costs... have a laser guide. The Harbor Freight saw of the same cut capacity, with the laser, costs $129 on sale. Bosch's equivalent costs $700... with no laser, only a blank cover where the laser otherwise would be, and in fact is in markets other than North America.
So I believe it when I read that Bosch doesn't like paying license fees for other patents, even when Bosch has already incurred the development and manufacturing costs to incorporate the patented feature in their products already. BigToe wrote:

That may change with the new Ford 7.3L gas engine.
If 8.1 liters of gas couldn't out pull 6.6 liters of turbo diesel in the mountains, what chance does .8 liters less of naturally aspirated gas have against .1 liters more of turbo diesel?
A Ford 6.2 will outperform their V10. A high compression Direct Injected big cube V8 could be a nice option. I didn't say it will outperform a turbo diesel.
Also there's been some rumor that GM is coming out with a 6.6 gas V8.- BigToeExplorer

2020? Or 2022? I read 2022 model year, available for sale in late 2021. Huntindog wrote:

It's really not that simple for me, but it may be for you.
There just are not any gas motors with high enough capabilities

And to think all of these CP4 failures could have been avoided by not using a cheap fuel filter and buying quality fuel. Quite a revelation there. - HuntindogExplorer
