Cummins ISB Diesel Engine Ranks At The Top

Just listen to that baby purr...doesn't it sound great? Cummins has won the "who makes the best medium diesel engine contest". These engines excel way beyond all others on the market. Caterpillar and Navistar collaborated with the MaxxForce design using HEUI injection and it could not keep up with emissions and those of us who still operate them are paying through the nose with repairs and labor to keep them on the road. Production has ceased for all MaxxForce diesel engines in the medium duty industry along with the latest shut down of the 9 and 10 models.

Mercedes MBE 900 engine manufacturing shut down years ago because of the same reason not being able to pass the emission standards. We still have several of these engines running in our fleet and are kept on our toes dealing with emission issues. They have a sturdy block and top end but could never keep the engine clean enough to run the way it should have in the first place. Soot and ash is everywhere causing constant driveability problems.

More reasons why my top pick is the Cummins ISB. It has the SCR system developed by Cummins engineers to reduce emissions down to Hydrogen and water. In other words zero levels of harmful oxides of nitrogen that pump directly out of diesel engine combustion chambers. Cummins uses diesel exhaust fluid to inject into a catalyst combined with the original diesel particulate filter design forcing bad emissions to it's knees. Our fleet will be nothing but Cummins ISB from here on in. There will be no guinea pig testing with us anymore with new diesel engine designs that salesman push with their over-enthusiastic promotions.

Sorry guys that's not going to work in our fleet. We've got our hands full trying to keep up with inferior diesel engines that fail constantly and pick away at our operating budget. It's easy to talk the talk but we are the ones that end up pulling our hair out for years. I would like to thank Cummins for designing the ISB diesel engine with the end user in mind. Everything that has to be serviced is easy to reach... your software is excellent and down time is minimal. Think red...Cummins red if you're thinking about buying a truck or a bus. You will keep a lot more cash in your wallet and you'll spend a lot more time on the road.
