Just like our road vehicles, construction equipment has moved into an era of cleaner-burning power plants. Engines with more environmentally-friendly performance values. And while that’s all good for the world around us, what’s good for your business is reducing costs. New Kawasaki loaders feature the most advanced engine technology that meets new regulations and helps drive a sustainably profitable future.
The new standard for engines is Interim Tier 4, often abbreviated Tier 4i. Kawasaki loaders now feature Isuzu‘s industry-leading 6W series engines that deliver all the latest high-tech performance in a package that offers unsurpassed ruggedness and reliability. Yet they’re quieter. And, best of all, they’re more efficient. Your Kawasaki warranty covers the engine, to two years or 2000 hours.
With technology evolving lightning-fast, and ever-more-stringent regulations coming into play, it makes a lot of sense to buy new Kawasaki loaders rather than used equipment. You get a fresh machine that’s engineered to steer you straight toward greater productivity and assured compliance. With reduced fuel consumption.
With Tier 4i engines, it’s all about cleanliness.
Keeping the atmosphere cleaner starts with keeping diesel fuel clean – free of the chemicals and particulates that can turn into the kind of smelly, ugly, even toxic emissions that lower air quality and damage your public relations.
To meet Tier 4i standards, these new engines use Ultra Low Sulfur Diesel (ULSD), so called because its sulfur content is less than 15ppm. By June of next year, all refiners will be required to meet this requirement. Using any traditional LSD fuel will nullify your warranty and ultimately cause expensive engine damage, so it’s essential to carefully monitor the fuel you purchase.
New fuel requires a new approach.
Above ground storage tanks are far preferable for ULSD, because they can be installed at a slight incline. That enables condensation to collect at the lowest point, where you can easily extract it. Smaller tanks are preferable, too, to minimize condensation and microbial growth and ensure your fuel supply is always fresh.
Best practices with ULSD call for filtering the fuel as it’s dispensed into your tank and again when it’s drawn out. You’re shooting for ISO 4406 fuel cleanliness, with contamination codes 14/13/11 or better. Obviously, an above ground storage tank makes filtration more convenient. You cannot use a galvanized tank, because the zinc reacts with diesel fuel, forming compounds that will make your engine run ragged and under-powered.
And, of course, you need to keep nozzles and anything else that comes in contact with your fuel clean.
Kawasaki loaders use what’s called a diesel particulate filter, or DPF, system to continue the filtration process. The DPF works to filter out or remove particulate matter from the exhaust. It also helps chemically oxidize exhaust, converting it into harmless gases. This system functions automatically, eliminating excess build-up of particulate matter in the filter, which could cause increased exhaust back-pressure. The procedures uses engine heat to do the job, typically taking 15-20 minutes.
However, if you use your equipment under low engine or machine handling conditions, or allow it to idle excessively, it won’t attain proper temperature. You’ll have to stop work to activate the manual regeneration system, which takes about 45 minutes to cycle.Kawasaki wheel loaders feature on-board diagnostics that monitor all this, displaying engine temperature and alerting you if there’s a need for manual intervention.
So you’ll have to learn some new tricks to keep your fuel clean and your new Tier 4i engine performing at peak levels. But all that high performance will keep you in compliance and on the job for years to come.
