Diesel's Dead? Bosch Think Not.

New Bosch tech drastically cuts diesel NOx emissions

This has appeared in a few articles in the motoring press. Some impressive claims being made about reduced emissions.

So it's still exactly the same technology being used, just better optimised. I used to work in the diesel engine industry and there's some very big companies out there that will continue to find solutions to the reduced emission regulations.

They will have to keep developing the technology as in my industry (heavy plant) there is no getting away from diesel so the cleaner/more efficient they make it the better.

The modern tech on our latest machines is so clean the fumes coming out the exhaust are cleaner than what was sucked into the air filter.

Mmmhm. Fully understand the principle of heat being used as a catalyst the take out the nasties. However when your exhaust manifold, turbo charger, EGR, DPF, SCR system and catalytic converter are all one component, that's going to be a fairly expensive item to replace when it goes wrong. As if they're not expensive enough on they're own

Those generally run to the 'Tier' emission regulations. I'm not sure exactly what the comparison is now, but they used to trailing that of the 'highway' emissions by something like five years.

That's not the only problem, you don't want too much heat in the engine bay as it causes other problems so it often suits the manufacturer to have them further 'downstream'. We have a Euro 5 Yeti, and the cat/dpf is bolted directly to the turbo so passive regens are easy to achieve.

Instead of "banning" new clean ish diesels , can't they just increase road taxes on the old diesel burners ........................

That may penalise those who could perhaps least afford it and persecute those who bought diesels when previous governments offered incentives to buy them.

If manufactures like Bosch claim to have the capabilities to keep cleaning the emissions from internal combustion engines, then just progressively tighten emission regs as we do now. Euro 7, Euro 8 and so on.

The increase in oil prices as the stuff becomes more scarce over time, combined with increased demand from a growing world population, will probably be sufficient to drive the development of alternative fuel and propulsion systems as it is.

DPF/DOC assembly on one of our machines are about £12000 + vat and fitting
