The warranty period for engines with ACERT Technology is 24 months or 3,000 hours, whichever comes first (with the first 12 months at unlimited hours).  A third year of warranty covers five major components:  cylinder block casting, cylinder head casting, crankshaft (excluding bearings), camshaft and connecting rods.

Announcement of the new warranty was made by Chuck Wills, marketing manager of Cat’s Industrial Power Systems. 

“Dependability and reliability, of course, are at the crux of any warranty improvement,” Wills said.  “We wouldn’t have extended our warranty coverage if we didn’t have enormous confidence in ACERT Technology, which now has proven experience both on- and off-highway.  Our customers are delighted with the performance of ACERT Technology.”
 
There are nine engines in the industrial ACERT Technology lineup, seven of which meet Tier 3/Stage IIIa emissions standards and two that meet Tier 2 requirements.  The Tier 3/Stage IIIa engines are:

• C6.6 ACERT rated from 119 to 250 hp (89 to 168 kW) @ 2200 rpm;
• C7 ACERT rated from 175 to 300 hp (131 to 224 kW) @ 2100/2500 rpm;
• C9 ACERT rated from 275 to 375 hp (205 to 280 kW) @ 1800/2200 rpm;
• C11 ACERT rated from 325 to 450 hp (243 to 336 kW) @ 1800/2100 rpm;
• C13ACERT rated from 385 to 520 hp (287 to 388 kW) @ 1800/2100 rpm;
• C15 ACERT rated from 440 to 595 hp (329 to 444 kW) @ 1800/2100 rpm; and
• C18 ACERT rated from 575 to 785 hp (429 to 585 kW) @ 1800/2100 rpm.

The Tier 2 engines with ACERT Technology are:

• C27 ACERT rated from 800 to 1150 hp (596 to 858 kW) @ 2100 rpm; and
• C32 ACERT rated from 850 to 1350 hp (634 to 1007 kW) @ 2100 rpm.

A little history:  In 2002, Caterpillar introduced ACERT Technology to the on-highway market, where emissions standards are tighter and the need more urgent than in the off-highway market.  Also in 2002 Cat introduced its first engine with ACERT Technology to the off-highway market, the C18.  Since then, an additional eight engines with ACERT Technology have been launched.

The Cat® ACERT Technology for emissions reduction revolves around precise control of the combustion cycle accomplished via a systems approach to air management, electronics, fuel systems and combustion systems. 

ACERT Technology blends both new and existing engine technology to meet the various global exhaust emissions regulations facing the diesel engine industry. While ACERT Technology is the same across all the engine families, there are differences, engine to engine, in how the technology is implemented.
